Right now, unfortunately, our player object looks like nothing. Otherwise the G-forces would prevent our player from being able to move! . This is a simple way to animate your character while moving. Edit Image However for our game we are keeping things simple and all those values can be left at their default settings. The next step in our GameMaker Studio 2 tutorial is where things start getting really fun. From here, you can move on in the development process to more game logic, doing some pixel art (although, how could you improve on my masterpiece here? Once the level has been drawn, we need a character to explore it. By the end, youll have built your first 2D platform game! , you created a sprite, assigned it to an object and placed an instance of that object in a room. By doing this we are adding -1 relative to the current value, ie: subtracting 1 from the current value. One of the benefits of GMS 2 is that it doesnt require a bunch of scattered dependencies to make it work. The videos that accompany each 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. While this isnt a full game, its enough to get a good feel for how GameMaker Studio works, and whether it clicks for you. 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. This sprite will hold the title screen text graphic, so open the tutorial assets folder and load the sprite "titlescreen.png". Now drag an instance of the controller object obj_spawnerinto the room and run the game. Youre also going to drag and drop your invisible ground layer a few times and resize it to perfectly match wherever you drew your tiles. 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). GML, or GameMaker Language, is GameMakers proprietary programming language. GameMaker Studio 2 Tutorial: A Simple 5 Step Guide to GMS 2 We have set the direction so now we use this action to set the speed to the variable we defined in the create event. Add Event Terms of Service and rapid development: The If this was not checked then we would be simply setting the cooldown variable to -1. You can name this sprite now, something like "spr_background", and close the sprite editor before continuing (we don't need to set the origin of this sprite nor any of the collision properties as they are not relevant for tiles). Happy developing! You should run the game again now, and you'll see that the experience is quite different to what it was before. x To so this we need to use the built invariable image_alpha. Resource Tree section. Well, most games have some form of goal to achieve and more often than not this involves shooting something, so in this tutorial our goal is to add in some enemies for the player to shoot. Now we can go ahead and create our spawner object. They can be any size you like, and GMS 2 has a camera/viewport system, so our room doesnt have to be the same size as our screen. In the previous Now, lets draw something simple to represent our character. . Many careers in tech pay over $100,000 per year. So what we need to do is draw the score text relativeto the view camera. Sprites are the game dev word for images. We are going to edit this now to dynamically create instances of the bullet object as the game is being played. The general Draw Event (and all other draw events) will be performed once for every game frame, much like the Step Event will, and note that you can have unrelated actions in the draw event as well as draw actions (but it is recommended that you keep this to a minimum and use the Step Events instead where possible). section Click on the Rooms folder in your Asset Browser, and youll see that you already have an asset called Room 1 in here. 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. Where GameMaker differs, however, is in its relative simplicity and target audience. Events event Here, you are multiplying the boxs speed by the time variable. We want to set the colour that the font is drawn in too, so now add the action Set Draw Colourlike this: The default colour is white, so we don't need to change anything there (although you could set the colour to anything you want by clicking the colour swatch in the action which will open a colour picker for you or by giving a hexadecimal colour value), but we need to un-tick the "Use alpha from colour" option, as we want the text to be drawn solid white regardless. The main points you should have picked up while working through this section 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. Powerful. How to use multiple "if" to check different conditions, How to create a new instance using an action, How to create new layers and change layer order in the Room Editor, How to create an instance variable and use it in other actions, Import an image (remember, while following this tutorial the file explorer should take you to the, Set the origin of the sprite to the middle (use the drop down menu), Assign the enemy sprite we just added to the new object, How to access variables in other instances using the "point" method or using the, How to edit the collision mask for a sprite and what effect it will have on the game, How to add collision events and the keyword other, Tiles will always be added to a grid the same size as the tile set assigned to the tilemap layer, You can select the empty tile to paint with and remove existing tiles, but you can also use the right mouse button, You can move around the room using the middle mouse button, How to make a view camera follow an object instance, How to set a font and a colour for drawing, How to add and re-order rooms in the resource tree, How to change the built-in properties (like image alpha) for drawing a sprite, How to change rooms using the Room actions, How to select multiple assets placed in a room, How to use image_xscale and image_yscale to change the scale of a sprite, How to use instance_change to switch objects, How to use an alarm in a controller to create timed events, A high score feature where the highest score ever is saved and shown to the user, Background music and better/more sound effects. In this case we use view port[0] since that is the one we set up in the room editor in the last section. of this tutorial You've made it to the Scoring Section of the "My First Game" tutorial and in this F5 obj_player . In this case we want to use local variables to store some return values from functions that we will use in the code. Next we add in the Assign Variableaction just as shown above, only we chain it to the right of the Assign toaction, as we did for an "if": Finally we want to destroy the bullet instance by dropping an Instance Destroyaction after (and outside of) the Applies toaction, so the final Collision Event looks like this: After we take the point of off the "hp" variable, we then call the action to destroy the calling instance (the bullet). We need an idea before we start prototyping, so lets come up with one now: Id like to make a top-down adventure game where you can slow down time to solve puzzles. Some of the best advice Ive ever received as an indie developer is to start your project right away. Its fortunate then that there are many other options available, such as the excellent GameMaker Studio 2. spr_player on it, which will open the Room Editorin its own workspace: Rooms can be used for just about anything. "Career Karma entered my life when I needed it most and quickly helped me match with a bootcamp. 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. Right now, nothing happens; weve got a bit further to go before this GameMaker Studio tutorial is through! This layer will be used to show the background tile sprite that we added previously. Adding the spawner objects has made the gameplay more dynamic and enables the user to play again and again and try to beat their own highscores. You'll see that we have the option to Stretchthe background image too. and set the width and height to 6464 pixels under Note that we are not setting the "speed" value directly, but instead will be using this custom variable to set the speed. Our workspace now has two boxes. You then made it move around with the arrow keys, and always rotate to point at the mouse position. 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? Essentially, the general Draw Event defaults to using the Draw Selfaction . 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). 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. sections then you've already got the beginnings of a small arena shooter game. Playing a sound is really simple and requires a single action, the Play Audioaction from the "Audio" library. We'll leave the shooting for the next tutorial in the series and simply add the rotation for now. So, here we are setting the scaling factor to be 0.1 (10%) and then we are going to scale the image up to 1 (100%) before spawning the enemy. Remember, everything that goes in a game room gets placed on a layer, and in the room editor we can name our layers to anything we require. 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". After completing this This is where we will be working on the art and code for our project, among other things. obj_somthing You can click the New Sprite button to create this empty image, then define the size of the empty image and its collision box. Thats because we havent given them anything to do, so they just stand where weve placed them. Name your project as you please and save it somewhere safe. There are a lot of options here, but the first thing we need to do is switch the view "on". While normally proprietary languages are a bad thing, GML is really close to JavaScript as its dynamically typed and high level. 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 For now, we can just use a static character that glides around the screen. Return to our player object and add a new event; but this time, go to The other options in the Font Editor are outside of the scope of this tutorial, but you can read up on them by pressing to open the manual and going to the section on the Font Editor. They will automatically be pasted after the previous actions, so you can go ahead and do this three times so that we have a total of four "if" checks: You can now edit the actions so that you have: As you can see, we subtractfrom x to go left this time, and we have also changed the last two conditionals to change the "y" position instead of the x position, where subtracting from "y" moves up, and adding to "y" moves down. 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. We couldhave created a tilemap layer for this and added the background as single tile, but with the background layer it's a lot simpler: just tick the Vertical tileand Horizontal Tilecheck-boxes: Before continuing let's just look at a couple of the other options for backgrounds. x Right now, its a little small. Step is essentially one lap of the gameloop. Being able to access variables in other instances is incredibly useful and very powerful, and it's important to know how and when it can be done. event for the world object. 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. Every time we shoot the enemy, we will deduct 1 from this value until it reaches 0 and it is removed from the game.
