I named mine Making child rooms is an advanced and powerful feature, but outside the scope of this tutorial, so just drag it into the position above the room "rm_game", as shown in the animation above for now. Like Unity and Unreal, GameMaker Studio, is a game engine that incorporates a powerful IDE (integrated development environment) for easy development. Now let's add some code to the player object. We turn the gravity off when we hit another object but we also need to set the vertical speed back to 0 to get rid of any lingering momentum. Note that because we already have the action Room Restartin the player object when they die, then when the player dies the title screen will be shown again, so the player can prepare before each game after dying. We actually need to use a functionto get the angle that we want to set the sprite to, and then we'll store the value it returns in a variable ready to set the rotation of the instance. This is where we will be working on the art and code for our project, among other things. So, if you want something to appear above or below something else, it should be placed on an explicit layer. Once you have named the resource and added the file, you can use the audio preview buttons in the editor to listen to the sound and set its volume: The rest of the options here we can leave at their default values, but if you want to find out more about them then hit to open the manual and go to the section on the Sound Editor. We want the bullet to shoot off in the direction of the mouse, so we need to add the following actions: Adding these into the Create Eventof the bullet object should give you this: Go ahead and hit Run now to see what happens: That's starting to resemble something that could be called a game, but there is an issue because we are creating the bullets on the same layer as the player, they are being drawn on top of the player which doesn't look right. Using that we are telling GameMaker Studio 2that the following action blocks are to be run as if they were part of the otherinstance in the collisions actions - in this case the obj_enemy. section All instances of objects have a number of built in variables that are related to how the assigned sprite will be drawn. By default, this will be set to Automatic, and you can see that in the preview window GameMaker Studio 2has added a darker rectangle to show the area of the sprite that will be used for collisions by default. Objects To do that, let's first change the Step Eventaction Instance Createof the object "obj_player" by simply changing it to use the player position (x / y) instead of the mouse position (mouse_x / mouse_y): Once you have made that change, we need to switch to our object "obj_bullet" (double click it in the resource tree, or use / + to bring up the Workspace Switcher). Now, create a new object (Ive named mine Now that we can move, lets make something that can hurt us, to provide a bit of a challenge for our players. The collisions are solid and look better, and there is a certain skill required by the player to avoid the enemies while shooting. section. and set the width and height to 6464 pixels under To get our score to go up as we play, we need to add some extra actions into the Step Eventof the object obj_enemy, so open that now if it is not open already. Tile Sets are always comprised of a single sprite image, and must always be based on a grid, although the grid does not have to be square, just regular, ie: you can have 24x96 tiles, or 32x32, etc as long as each part of the tile set image is on a grid it can be used in GameMaker Studio 2as a tile set. Once youre in the Instances layer, you can simply drag and drop your character into the scene wherever you want it. A game in GameMaker Studio 2is simply a selection of code within events that are performed a number of times every second. , and make sure the Game frames per second is set to 60. We are going to use the following image: You can get the above tile set from the TutorialResourcesfolder that the tutorial made automatically, in the "Images" sub-folder, when you click the Import button (if you have any issues, you can also find the images here). section This layer will be used to show the background tile sprite that we added previously. The With this sprite we need to change the origin. This area is the actual room, which is currently a blank canvas on which you can place resources to create your game level. Create If they are, the player moves one step in that direction: Do the same thing for the other direction. This means that it is created when you use the action and then discarded again at the end of the event or script that created it. on resource name and call the room "rm_game". To open it for editing you need to double-click This is a bit of forward thinking on our part, as we will eventually have the player "die" in our game, removing its instance from the room, and if we try to access the variables of an instance that. Its fortunate then that there are many other options available, such as the excellent GameMaker Studio 2. Espaol - Latinoamrica (Spanish - Latin America), https://www.youtube.com/playlist?list=PLhIbBGhnxj5IF9saL3KNqeJqHKGHHeLFh, https://www.youtube.com/playlist?list=PLhIbBGhnxj5IcGWhJQNF5hScmCCn4M3xg. The actions will be like this: Let's just go through the actions here one at a time so you can see what is happening: So, if there is an instance of the player, we then tell the enemy to move at the speed of the "spd" variable towards it. You'll notice that our object has another window chainedto it, the Event Editor. section You can click the New Sprite button to create this empty image, then define the size of the empty image and its collision box. The only resource that is created for you by default when you create a new project is the Room Resource. we have added yet another object to our game, the enemy, and got things feeling a bit more like how an arcade game should feel. This . That was a good start, but it still wasn't a game, so in this tutorial we're going to add a shooting mechanic to the project. The final game will look something like this: We will be keeping the tutorial as simple as possible, with the idea being to give enough of an overview of how things work for you to get stuck in and making your own games as quick as possible. x=x-5 The new room will be added after the current one: We'll call this new room "rm_titles". . Objects This is because all games require at least one room to run, and so GameMaker Studio 2makes this room for you. In this case we are going to change the alpha to make the sprite "invisible" at the start of the room. are as follows: That might not seem like much, but with this knowledge you can start to set up more complex displays for your player to include any number of written details, and format it to follow the view camera at the position you want. Note that we are not setting the "speed" value directly, but instead will be using this custom variable to set the speed. Since it doesn't have a sprite it will be shown with a question mark icon . The All instances have some built-in variables, of which "x" and "y" are perhaps the most important as they set the position of the instance in the game room. Here's many tutorials on the internet and amazing manual. GameMaker Language Welcome to the GameMaker user manual! If you click on the Play button at the top of the screen, you can test out what youve built. Now, we can attach the sprite to our character object, and put that object into our room. This means that changing an instance's properties will not change the properties of the object it was made from, however changing an object will change all subsequent instances created from it. Read tutorials from experienced game developers and GameMaker experts. The idea behind an object is to create a kind of blueprint of behaviours that can then be used within a game. Go back to the controller object obj_scoreand make sure you have the general Draw Event open as we need to edit it. , you created a sprite, assigned it to an object and placed an instance of that object in a room. Creating a sound resource is exactly the same as creating any other resource. we will change that by making it more attractive to the player using tilesand also expand the play area using cameras. In the next You can delete it, and you can edit it, and you can create further rooms using the right button Change the dropdown menu right above the preview of the sprite from You can do this by clicking on the tile layer icon in the Room Editor window this looks like an isometric grid. The layer has been created abovethe player layer, which means that anything assigned to it will be drawn afterthe player, which we don't want. Simply click on the Background layer in the Room Editor window, then select a sprite underneath. This means that should we want to change it, we onlyneed to change it in this one event, and all the rest of the actions will "just work". However we want to edit this as it is too large for what we need, which means you have to click the Modebutton and select Manual. In this event, the code is pretty easy, just put in the following: Ill let you guess what this code does. Throughout this tutorial we will build a small "arena shooter" - a top down action game with a player, some enemies and lots of bullets. First you would open GameMaker Studio 2 , and then click on the New Project button shown on the main Start Page:. We are going to expand on the current actions to include a check to see if the "hp" variable we initialised previously is less than or equal to 0, and if it is we are going to destroy the instance (remove it from the game room). Before continuing to add these spawner objects, we first of all need to remove the enemies that are currently in the room and prepare a new instance layer, so open the room "rm_game" now. These are the default layers created for any new room, where the background layer permits you to use a colour or a sprite for a single background image, and instances permits you to add instances in to the room. Create Object. section Were going to create another object, too. That aspect of the program won't be discussed in this tutorial and we'll be using the default layout, but you can find more information on customisation in the manual (press By default GameMaker Studio 2will use a draw colour of white for everything, but at various points in your game you may wish to change this, and it's good practice to explicitly set the draw colour before drawing anything, so that is what we are going to do now as well as draw the text itself. Call this object Player and select the sprite you made earlier. on it, which will open the Room Editorin its own workspace: Rooms can be used for just about anything. With help from Career Karma, you can find a training program that meets your needs and will set you up for a long-term, well-paid career in tech.

Now add a Create Event: We are going to have our object draw its sprite fading in gradually, just to create a slightly nicer looking title screen. The game Frames per Second setting can be changed in the Game Optionswhich you can open from the button at the top of the IDE, or by going to the Resource TreeMainoptions item: As you can see from the image above, here you can change a few things that will affect how your project will run, including the game FPS value. There are different types of workspace too, but we'll cover that a bit more later. which will be a completely empty object with physics once again disabled. In this case we have named the variable "dir" and in future actions that will be what we use to refer to it. under We are going to place this action into the enemy object obj_enemy, specifically in the Step Event, just before we destroy the instance. But you can change it to Drag & drop is meh but you can use it anyway. dropdown in the Heres what our logic is going to look like: So, if there is an object at position Y + 2 (two beneath the player) then set the gravity to 0 and set the vertical speed to 0. Click the Add Eventbutton now and select the Draw Eventcategory: As you can see, there are multiple draw events to choose from, but for this we simply need the general draw event, which is the one at the top of the category list (highlighted in the image above). This name will be the uniqueidentifier for the sprite throughout your game and can be anything you wish, although we recommend that you use some kind of identifier prefix like "spr" or simply "s", as, when you get multiple resource types in your game code, it makes everything far easier to read. For this tutorial we are going to use Drag & Drop so you would click that button and then choose a project name to go with the game you want to make. We wont make a sprite for this one; we dont want to see it. We now need to add an image to the sprite to use as our player. we are going to dedicate to adding some sound to our game. section, we are going to show you how to set up a basic title screen for your game using a new room and with some extra graphics. Thats about all you need before entering the prototype phaseno design document, no multi-step plans (yet). Right now, its a little small. This will open the Tile Set Editor: The tile set window is comprised of two parts to start with: the main Tile Set Editorwindow which has the Tile Set Propertieswindow chained to it. . For now, we will just leave it set at default with the room taking up the whole game window. However, Ive found that visual coding languages like Drag and Drop tend to hold back developers that would be better off just buckling down and learning code. GameMaker Studio 2 If you need to change this, you can select the Collision Mask drop-down menu on the left, and then select Manual under mode. All this will do is stretch the background image used to fill the whole room area, which with a small image like the one we are using doesn't look right, which is why we tile it instead. Execute BAPI module in SAP GUI system. Clicking this will animate the whole room such that any backgrounds that are set to move, or tile sets that are set to animate, or any sprite assets that have sub-images will be shown as they would appear in the game: With the horizontal background speed now set to -2, this will add interest to our title screen, we can continue on to make our title object. Im using a pretty starfield. However "other" in that context onlyworks for the collision event, and we want to apply an action to an instance in the Step Event, so we need to change the scopeof the action we are going to use. Resource Tree The general draw event is the one that GameMaker Studio 2uses when it default drawsyour instance sprite. So, in our actions we are setting the alarm[0] to 60, meaning that it will subtract 1 from 60 every game frame until it reaches 0 at which point any code in the alarm[0] event will run. By default this is set to 30 by GameMaker Studio 2for any new project, which is fine for puzzle games, or games that don't require fast response times or even for mobile games, but for arcade style games like ours a preferred value would be 60. We then need to get the position of the view camera within the room space, so we use the Declare Tempaction two more times: There is no action available for getting the position of a view and so we have to use a function in the "value" argument. to begin making your first game. That action will also draw the assigned sprite along with any applied transforms, just like the default drawing for an instance when it has no Draw Event. We are going to make a new object and call it So, still in the obj_enemyStep Event, and before the action for playing the sound, we need to add the action Set Audio Pitch: When you use a sound effect or music in GameMaker Studio 2it is played with a pitch value of 1. Our tile set is now set up and ready to add to a room We need to go back to the Room Editorworkspace now, as we want to create a new layer called the Tilemap Layer. This score will then be displayed prominently at the top of the screen To keep things clear and easy to manage in our arena shooter project, we need to make a new object to act as our main "controller" object for the score. You can resize these objects by simply grabbing an edge and pulling. Learn about the CK publication. . We have no need to change any of the properties for this sprite so you can close it now and then create another one and call it "spr_titlescreen". If you wish to play around with what you have learned so far, we recommend that you save the project in its current state - so that you can continue from the same point later - then save it again with a different name and edit the renamed project so as not to lose or change anything that is important to future If The next step in our GameMaker Studio 2 tutorial is where things start getting really fun. Getting started with GameMaker. Instance variables are valid for any event in an instance and can be changed or read in other action blocks. We could, for example, have created a "BulletsLayer" in the room editor, and then used that to explicitly say we want the bullets on a unique layer - the action for that would have been simply: You can see there that if a layer has been created in the room editor, we can use its name as an identifier to target it within this action (and a few others). Before we end this tutorial, let's quickly add in a collision for the player colliding with the enemy. Click on the Rooms folder in your Asset Browser, and youll see that you already have an asset called Room 1 in here. The bullet instance we are creating is created using the Instance Createaction , which creates the instance and assigns it to the layer ID that you give, - in this case the default Room Editor layer for instances. Its easy to read and type in, and it functions very similar to other languages. We need to style the text on the screen to make it more readable and nicer to look at and for that we'll start by adding a new Font Resource. You can change this value if you wish, but by default it's locked and handled by GameMaker Studio 2automatically. Basically, some tile set images may be created with "empty" areas around each tile and so you can set the pixels or cells between each individual part of the image here. Quick tip: if ever youre looking for information or help online, make sure you search for GameMaker Studio DND. This short hand will ensure you get information relating to the drag and drop version, rather than GameMaker Language (GML). we now have a nicer introduction to the game. We want to now make the player instance move when the user presses the Arrow Keyson the keyboard. is also accompanied by a short video that takes you through each of the steps outlined in text, and you can close GameMaker Studio 2at any time in the progress of this tutorial (saving your project) and when you next load the project you will be taken to the place where you left off. We are now going to use this variable in the Step Eventof the player object to control how often the shooting occurs, like this: What we have done is "nest" an if variableaction within the mouse down action, so it now reads "if the mouse is held down, and if the variable cooldown is less than 1 {do something}". Essentially, the general Draw Event defaults to using the Draw Selfaction . section The image itself is a large translucent PNG that has a 3232 pixel square in it. The first thing to do is tell GameMaker Studio 2that we want to draw with new font resource, so before the Draw Value action we need to add a Set Fontaction like this: As the action name implies, this will set the font for drawing any text. You can get quite far using the drag and drop system, but really it depends on what you want to do and how complex you want to design your project. In this short While this isnt a full game, its enough to get a good feel for how GameMaker Studio works, and whether it clicks for you. was equal to the number of pixels on the screen, our object would be at the far left. Anywhere is fine. We have covered all the basics that you need to know to get yourself started making games, and we've given you a base game to work on and try to change or add to. For this we need to add a Create Eventfor the object "obj_player", and in it add the following action: All we are doing here is preparing a variable called "cooldown" for use later on in the game - remember, the Create Event is only run oncewhen the instance is first created, so this variable is being initialised to 0 once only. In this case we use view port[0] since that is the one we set up in the room editor in the last section. (for the object) and How to make Android games for complete beginners, How to create a simple 2D platformer in Unity Party One. This will compile and run your game. You can have multiple camera views in a room, and they can all be enabled and displayed at different positions (permitting, for example, a two player split screen game, with a camera view for each player), however for our game we only need one, and that's the camera View 0. In this case, Im using green semi-transparent squares. Lets make sure it all worked and press section Valve Corporation. automatic The Sprite Editor will now look like this: The top part of the editor will show a single image, and the main window will have a larger preview. and then add it to the player object. Now that its the right size, lets draw on it. By default this is set to 0 for every instance in the room, but it can be changed at any time using the Set Instance Rotationaction . When you start a game, you aren't normally just dropped straight into the action, but instead you are usually presented with some kind of title screen. With this action, we check to see if there is an instance of the player object in the game room because later we want to access certain variables from that instance. on the "obj_player" object in the resource tree. Right-click the to zoom it in and out. We have our enemy spawn object now, but we don't have anything to re-spawn the enemies when there are none left, so for that we are going to create a controller object called obj_spawner. A GameMaker Studio 2bases all the scale on factors, where a factor of 1 is 1:1 with the original sprite image, so a factor of 1.5 is 150% bigger and a factor of 0.5 would be 50% smaller. Step The Key Up Event detects when a key has been releasedand won't trigger until that happens. It has everything you need to take your i. For more developer tutorials and news from Android Authority, sign up below! Let's go ahead and create our first sprite resource. They are special events that will count down every game frame until they reach 0, at which time they will perform the action code added into the event in the object. I know thats a very small number, but remember that this will happen 60 times a second. While normally proprietary languages are a bad thing, GML is really close to JavaScript as its dynamically typed and high level. While you've been testing your game, you may have noticed that the bullets don't often actually appear to hit the enemies when they disappear yet the hit is being registered, and the bullet is disappearing and the enemy "hp" is being affected. Click on the layer and drag it into the position between the Instancesand BulletsLayer. When you import the image, you'll see that it is covered in a grid that is 16x16px per cell. You don't need to assign a sprite to it, but you will need to open up the Create Event. Learn about GameMaker Studio and make your first platform game! so dont make it black section We've seen built-in variables already, but this is one you are creating and it's called an instance variable. The final thing we need to do is set the Object Following. This is a drag-and-drop tool with relatively less cording involved than many of its rivals. We're going to create a score for the player to use as a measure of how well they are doing in the game, and not only will we be keeping score, but we'll be using the different functions for drawing text to show it to the player as well. However they are also unique to each instance, so if you have 100 instances of "obj_player" in your game, they will all have an instance variable "cooldown" since you defined it in the base object, but each one could have it set to a different value throughout the time the game runs. With that done, the full action list for the general Draw Event should now look like this: You can now run the game again and you should see that the score is much more visible, maintains it's position and goes up when an enemy is destroyed: In this section . This tutorial has created a TutorialResourcesfolder for you within the project files, and when you open the file explorer to choose a sprite, it should open on that folder where you can find the sprites used in the "Images" sub-folder. With that done, you can go back to the game room and on the new EnemyLayerlayer add five or six instances of the object (click on the obj_enemyspawnobject in the resource tree and then drag it into the editor window and release the mouse button). Its also useful if you want to name two different things the same name, like Obviously the first thing we are going to need is a new sprite to represent a bullet. In this If you run the game at this point, you will find that you now get a massivegame window that is way to big for most people to actually play in, so we need to sort that out using cameras. We currently have the following actions in that event: We need the enemy to add a value to the score object variable "thescore" and so for that we will use the Applies Tooption in an action. Drag & drop is meh but you can use it anyway. But, for now, lets keep it at the section There are a lot of options here, but the first thing we need to do is switch the view "on". Keep in mind that instance variables need to be initialised before use, and so that is why we have them in the Create Event, as that event is run for every instance the moment it is created in a room and the event only runs onceso the variable is only set once at the start. Unlike the Step Eventthat we used in the player object, the Create Event will be called only oncewhen an instance of the object is first created in a room. That brings us to the end of the Shooting Section of the "My First Game" tutorial. On the left is the space where we can assign the object a name and a sprite, along with some other options. Next choose the "Drag and Drop" option, which we will be using for this GameMaker Studio .
