Note that if we want to go to a specific room without following the order of the resource tree, then we would use: The Room Gotoaction lets us go to any room in the resource tree (you can press to open the manual and see what all the other room actions are). Now set the tile width and height to 32.. Now we have to make the time variable do something. . This Build this flow chart yourself by dragging the elements from the right and placing them underneath or next-to the commands they follow on from logically. That way, the user can move with the keyboard and aim and shoot with the mouse. We can expand the current action list now to cover the remaining three directions of up, left and down. Next we need to add a Step Eventwith the following actions: All this action block is going to do is add a small amount to the image_alpha value and then check it to see if it is over 1, and if it is it resets it to 1. How to use GameMaker Studio 2. Playing a sound is really simple and requires a single action, the Play Audioaction from the "Audio" library. , and make sure the Game frames per second is set to 60. We have set the direction so now we use this action to set the speed to the variable we defined in the create event. Generally this is what you want for music or ambient effects like a wind or waterfall sample, but not for single sound effects like this. statement: To break down the code a little, first we check if time is below 1. In this GameMaker Studio 2 tutorial, we will learn how to make a game by You can click the New Sprite button to create this empty image, then define the size of the empty image and its collision box. section that depends on what you're planning on making. to zoom it in and out. To answer that we need to back to the Sprite Editorand explain another of its features - the ability to set up a collision mask. Many careers in tech pay over $100,000 per year. This is a great method to add more life to your games and can be applied to almost any repetitive sound effect to make it more interesting and realistic. Else (otherwise), set the gravity to 0.5. 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. We now get to see an . Before going any further though, let's just go over a few of the core concepts that you should take away with you from this Now, this isnt much of a challenge: the red box isnt very big, and its easy to avoid. . x (for the object) and Switch back to the Room tab and then select the Instances layer in the Room Editor window. The image itself is a large translucent PNG that has a 3232 pixel square in it. We only need to set the key that is being checked now, so change the "vk_space" value for "vk_right" (the "vk_" variables are special built-in constantsthat are used to signify different keyboard keys). The first is dropping it onanother rom (the room being dropped on is highlighted), which means that you want the selected room to become a "child" of the other room, and the other is dropping it over a room (where a bar is highlighted above the room), which will place it in the room order. The next step in our GameMaker Studio 2 tutorial is where things start getting really fun. Since weve just gotten the program, lets look over the interface. We can set this up from the room editor too, from the section titled Viewsin the Room Properties. If we set this then we are telling the view camera to only move by a specific amount each game frame, so that if we set it to (for example) 5, then the view camera will follow the player only 5px per game frame. creating a prototype around that idea When you execute the module, you get the following output. In this case we are going to change the alpha to make the sprite "invisible" at the start of the room. if To start with, drag an Assign Variableaction into the action workspace and position it abovethe Destroy action : We want to set this action so that it changes the "thescore" value in the object obj_score. To create the object, right click You don't need to assign a sprite to it, but you will need to open up the Create Event. make your own game! We are going to make a new object and call it Currently the player instance is on the "Instances" layer, and we need to add a new layer for our bullets, so click the New Instance Layerbutton to create a new layer and name it "BulletsLayer" (to rename a layer, simply slow-click twice on it). The second part of the code checks to see if the Y position of the object is at the bottom of the screen. However our tile set has all the tiles packed right beside each other, so we don't need to worry about this. 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. Again, like the Set Fontaction, this will set all further drawing to use the given colour (and not just for text either, this will affect shapes that are drawn and few other things), and so can be called once at game start if the colour isn't going to change, or once every time that you want to draw with another colour. We've covered this previously, but just to remind you, simply click on the Origin drop down menu and select Middle Centerto position the origin in the exact center of the sprite. Origin Per the box Ill name this Drag and Drop is simply more work for less functionality, so well be sticking with GML for this tutorial. Currently we are adding 4 to the "x" value every game frame, so what we want to do is only add 4 if the keyboard right arrow is being pressed. Right now everything is looking very empty, so lets get started making our game. automatic Now, on with the GameMaker Studio tutorial! This permits users to develop and publish games for Windows and MacOS. Youve made a (hopefully) functioning prototype for a new game. You can close this sprite now and we'll move on to creating the title screen room. If you try it out, its almost impossible to get past the red box without dying. GameMaker Studio 2 You can close the Sound Editor now as we are finished with the resource and are ready to add it to our game. Its really important to type everything exactly when youre writing code. However it's missing one or two things to take it from a prototype to a finished game, one of which is a scoring system which is what we'll cover in the next By the end, youll have built your first 2D platform game! GameMaker Studio 2 is a 2D game engine; so if you have dreams of building the next Doom, then youll need to look elsewhere. To open it for editing you need to double-click sections. Now, lets draw something simple to represent our character. we'll expand on what you've learned here by adding bullets and other world items into our Arena Shooter game. The new room will be added after the current one: We'll call this new room "rm_titles". You can change this manually by clicking on the preview. 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. . We need to add a Create Eventto our bullet. Youll now be greeted with a Workspace on the left and an asset browser on the right. This is now an easy thing to fix, as it requires a simple change to the number of frames we wait between creating each new bullet instance. section You can do this by clicking on the tile layer icon in the Room Editor window this looks like an isometric grid. Next Your full action list should now look like this: If you test the game again now, you can see that the bullets fire a bit slower, but for our purposes it still seems too fast. 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. . Right now, its a little small. Review the Import options for this module. This means that we now have to re-order the rooms so that the title room is placed before the game room. event and a new window containing a text editor to type your code into. Even if you're not a programmer you can do it. 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. to run the game. Putting ), or making a more complete plan with a game design document. In this room, we are going to create a new layer specifically for our enemy instances, so create a new layer now (click on the New layericon ) and name this layer EnemyLayer. Things to consider adding to this project would be: The list could go on and on, but it's entirely up to you what you do from now on. 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. We check to see if the pixels next to our player are clear. This can be really useful and can give a nice "catchup" effect if the instance being followed moves faster than the values given, but for our game we want the camera to alwaysstay centered on the player, so we leave it at -1, which is essentially telling the camera view to move "instantly" to the instance being followed position every game frame. This should be dragged and added to the right of the "if" action to show that it should only be run if the condition returns true: To keep things simple for now, the arguments we are going to use in this argument are as follows: The last argument can be kept blank for now as it's not required, but for future reference, the Target argument permits you to assign a variable to hold the unique instance ID of the instance being created, which permits you to change things on that instance later as well as many other things. Even if you have enabled views, if you don't have one that is set to be visible you won't get the desired result. Each loop is called a game frameand so we call the speed at which a game runs the game Frames Per Second (FPS). There is a minor problem that we have to fix now, though GameMaker Studio 2will run rooms in consecutive order, meaning the room at the start of the room resource list is the one that will be shown initially when we start the game. menu. Resource Panel In this event we want to add a single action, the Room Goto Nextaction (from the Roomslibrary): There are a number of actions available for moving between rooms, but we only need this one since it simply goes to the next room in the Resource Tree, which is our game room. Thats because it doesnt have a The only other thing to change is the This will make sense in a moment! Going back to our game, if you press Run now then you can test our bullet creation actions: Hmmm That's not really what we want is it? This is necessary because the tiles themselves are in the Tile layer and dont have any impact on our game objects. (for the sprite). This is a powerful tool if you want to get a 2D game running quickly, and that can only be a good thing for gaming on the Android platform. GM Version: GM Studio 2 Target Platform: ALL Download: N/A Links: N/A Summary: Simple drag and drop method for animating an 8 direction character in GM2. That brings us to the end of the Shooting Section of the "My First Game" tutorial. To get started with GameMaker Studio 2, first create a new project. For that we use the if key downaction which will evaluate to either true or false if the given key is being held down, and if it evaluates to true, then we will move the instance by 4. ,
