In this case we want to use local variables to store some return values from functions that we will use in the code. When you drop the sprite in, you should see it automatically open up in a separate window for closer inspection. However note that in generalyou want all sound effects to be *.wav format and all music to be *.mp3, and *.ogg can be either, but is generally preferred for longer sound effects and music too. However, if you have zero coding experience, you should still be able to follow along. Switch back to the Room tab and then select the Instances layer in the Room Editor window. By the end, youll have built your first 2D platform game! , youll see we have a default starting room for our game. Read tutorials from experienced game developers and GameMaker experts. This post will serve as a GameMaker Studio tutorial to get you started, and an overview of the tool. 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. While I really enjoy using GameMaker Studio 2, there are a plethora of paid and With this action we will set the built in direction variable to the direction from the (x / y) position to the (mouse_x / mouse_y) position. Go ahead and run your game again. In this case we are going to make a sprite to represent our player. By default this is set to 30, meaning that our game will perform a game frame (loop through all the game code) 30 times every second and in each single frame of the game code you have Events. and rapid development: section Make Your Own . By continuing you agree to our I named mine An event is simply an action or change that occurs within the room. After you change it you will see that the room in the editor has now expanded to twice its width (you can use the zoom controls to expand the viewable area if you can't see the changes, or alternatively hold down / and then use the mouse wheel to zoom in/out). Collision Detection If the game detects that youre pressing left on the keyboard, it will run the code in the curly braces. The only other thing to change is the By default a view camera is static, ie: it won't move unless you code it to, but we can set it to follow an instance of an object automatically and without code using this button: Once you've set it to follow the player object, we also need to set the Horizontal Borderand Vertical Bordervalues. For example, Undertale, Hyperlight Drifter, and Hotline Miami were all made using GameMaker Studio. The logic that goes here is pretty self-explanatory. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. statement: To break down the code a little, first we check if time is below 1. If you have used your own sprite then click the image where you think would be best place to put the origin for the image. . On the right of the workspace we have the Resource Tree, which lists all the different elements your project can use, like sprites, or objects, or rooms. However for our game we are keeping things simple and all those values can be left at their default settings. we will change that by making it more attractive to the player using tilesand also expand the play area using cameras. Using / like this will group all the instances together so that you can do things with them like move or, as is the case here, delete them. If it isnt, we check if the player is pressing A on the keyboard. Step For now, lets put the Even if you're not a programmer you can do it. This code makes sure time stays between 0.1 and 1. section Go back to your damage object and change the code so it looks like this: I know we said we would be controlling time, but controlling the speed at which the box moves is much like controlling time, and its a lot easier. Lets make sure it all worked and press Explore your training options in 10 minutesGet Matched, Resource Center > Software Engineering > GameMaker Studio 2 Tutorial: A Simple 5 Step Guide to GMS 2, Ethan Scully With this sprite we need to change the origin. Our GameMaker Studio 2 tutorial is almost done! Debugging is no fun, so try to copy the code exactly. With that done you should have a full set of actions that looks like this: You could drop this instance into the game room, but all you'd see would be a "0" on the screen since we don't actually add to the score value yet, so let's do that now. The Key Up Event detects when a key has been releasedand won't trigger until that happens. spr_damage 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. 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. Normally you'd have a mix of both things, with some rooms fulfilling multiple purposes (like one room for all your different menus) and other rooms for a single purpose, like an overworld room, or a level room. 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. In this GameMaker Studio 2 tutorial, . is the exact point that the game considers your player to be. 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. You can now select the Instanceslayer and then in the actual room editor workspace, use / + to select all the enemy instances one at a time. ). are what they sound like: places for you to put your sprites and game objects. There are a lot of options here, but the first thing we need to do is switch the view "on". variable 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. In the main editor window, you have a bunch of tools in the top right corner: The one we are interested in here is the Play Animationbutton . There are different types of workspace too, but we'll cover that a bit more later. Obviously the first thing we are going to need is a new sprite to represent a bullet. Once youve finished, return to the main workspace. 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. You can test the game now and kill a few enemies to hear the sound play. To make this easier we are going to use a couple of local (temporary) variables. In this Objects section make your own game! So you can have a camera view that is 480x320 (for example) but make the camera port 960x640 and the camera view will be scaled up to fit. Every game needs sprites, so take yours and drop them into the Sprites folder. 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. Edit Image Call this object Player and select the sprite you made earlier. We want to now make the player instance move when the user presses the Arrow Keyson the keyboard. View Tutorial. . With a simple idea in mind, its time to So with that in mind, call this sprite "spr_player". Open the action editor in the Step Event(double click the event if it's not open already). This is the equivalent of a scene in Unity. One of the benefits of GMS 2 is that it doesnt require a bunch of scattered dependencies to make it work. 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. 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. Every engine is different or powerful in its own way, and if youre still searching for the best engine for you, my advice is to keep trying different ones until you land on one you enjoy using. left off. Execute BAPI module in SAP GUI system. GameMaker Studio 2will always use the first tile of a tile set as a "blank" tile, which is what is placed by default as an empty tile. This provides you with something you can actually see: real results. Note: These functions will return the (x/y) position of the view and store each one in the temporary variables "cx" and "cy", and note how we use the previously declared temporary variable here. 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. + the mouse wheel Instance variables are valid for any event in an instance and can be changed or read in other action blocks. This is called the "game loop" and a single game loop is called a game frame. : Hopefully when you look at that list you can feel proud of yourself. At the moment, our bullets are created 1 per game frame (every time the game loops round and performs the Step Event again), which is a bit too fast for what we require. 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. Basic sound is incredibly easy to do and so this You can then simply draw onto your grid to create your level layout! We want to add a tilemap layer between the background layer and the bullet layer so click the Add Tilemapbutton to add the layer first, then click on it and drag it to position it between those two. On the left is the space where we can assign the object a name and a sprite, along with some other options. near the size button. . As mentioned briefly in a previous tutorial, all games run at a speed which is defined by the number of times the game loop runs in a second. To achieve this we are going to use another Room Resource, so right click on the Room resource folder and select Create Roomto make one. Since weve just gotten the program, lets look over the interface. To move from one room - the title room - to the next one - the game room - we will need a new object, so go ahead and make one now (Right click on the object resource folder and select Create). GameMaker Language vs Drag and Drop GML, or GameMaker Language, is GameMaker's proprietary programming language. , go to 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. GameMaker Studio 2has given you the tools, so use them to the make the games that you have always wanted to make. 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}". This will make sense in a moment! What's happening? So we can't write: That code will subtract 1 from ANY of the instances of "obj_enemy" in the room, and so is best used when we know that there is only one unique instance to be accessed. This grid shows the way that the image will be split to create the final tile set cells, and if you have used the tutorial image you can probably tell that the current settings are way to small for the image we are using. For this we add the Set Instance Alphaaction into the Create Eventand set it to 0: We also want to make sure that the sprite will be drawn in the exact centre of the screen, so we need to add the Jump To Pointaction, from the Movementlibrary, like this: This action will set the instance to the position specified, and in this case we are using the globalvariables, room_width and room_height to get the middle of the room (half width and half height) for the instance when created. Note that we are not setting the "speed" value directly, but instead will be using this custom variable to set the speed. Dont worry too much about the origin, and the bounding box should be all of the image now (which we want). The smart thing is that there is an Auto Tiling option that will automatically make that judgement call for you. This then, is where we want our gravity to go! Here, you are multiplying the boxs speed by the time variable. Resource Tree Now, this isnt much of a challenge: the red box isnt very big, and its easy to avoid. This should be set to 3232. 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. at the top left of the IDE. While normally proprietary languages are a bad thing, GML is really close to JavaScript as its dynamically typed and high level. or tutorial_game_files.zip Assign the object the enemy sprite too (spr_enemy), as what we are going to do is make our enemies "grow" in size and then spawn, so that the player has a visual cue that the spawner is there and that an enemy is coming and they can move out of the way and prepare. . The next step in our GameMaker Studio 2 tutorial is where things start getting really fun. In this case we are telling GameMaker Studio 2to take the x position value and then add 4 to it. Create In a later tutorial in this series we'll look at creating a "wall" around the arena so the player can't leave the room area, but for now we have what we wanted. You should be able to move freely around the screen. . This will be your players starting position. section GameMaker Language vs Drag and Drop . We need to add a Collision Eventhere to detect the collision between the bullet (the calling instance) and "obj_enemy" (the colliding instance): Now, in this event we will need to affect the "hp" variable of the colliding instance, and we saw that we could do this using the "point" method previously. We are going to use the rectangularcollision mask, but we need to change it's size. section section Its fortunate then that there are many other options available, such as the excellent GameMaker Studio 2. ) and move the instance with the arrow keys: We are almost finished this tutorial, but there is one final thing we want to happen with our player instance We need to make it rotate to always face the mouse while it is being moved around the screen.
