So when we talk about something affecting or changing an instance, that you see in the game are actually all considered as being instances.Īn instance is essentially a "copy" of an object that is found in the Asset Browser and then placed in a room (think of objects as templates for instances). In a game made with GameMaker Studio 2, the characters, monsters, balls, walls, etc. Now, we can't talk about Objects without talking about Instances. Objects can be given behaviours and they can react to certain events as well as to each other, and most of the things you see inĪ game are based on objects and their interactions with the user and each other. Scenes" controller objects to do things like track stats, or set timings for cut-scenes, etc. Most of the time they have a sprite associated with them so that you can see them in the game rooms, but sometimes they are used as a "behind the Objects are a special asset that we use to control aspects of a game and to do specific things. Come up with a list of all of the different pieces of information that you have used to control how these shapes are drawn.With the assets you have seen so far you can add some nice images and sounds to the game asset browser, but they don't do anything in the game itself yet! For that we need the most important assets of all in GameMaker Studio 2, the Object asset. Think, Pair, Share: So far we've only written programs that put simple shapes on the screen. What if you wanted to change any of those values during your program, or control other things like rotation? How Much Information? How do you tell a shape what color it should be? What about its outline? How do you tell a shape what size it needs to be? How do you tell a shape where to go on the screen? If students are struggling to come up with ideas, you might use some of the following prompts: The goal here is to get students thinking about all of the different values that go into drawing a single shape on the screen, and how many more values they may need to control a more detailed character in a program.
Later on, these sprites will become a useful tool for creating animations, as their properties can be changed and updated throughout the course of a program. Using the Animation Tab, students can create or import images to be used with their sprites. You can access them through dot notation. Properties are the variables that are attached to a sprite. A sprite is just a rectangle with properties for controlling its look. In Game Lab we use a certain type of object called a sprite. Instead computer scientists created something called an object which allows for one variable name to control both the shape and all its aspects. There will be lots of variables with different variable names. Keeping track of many shapes and the different variables that control aspects of those shapes can get very complex. Every sprite can be assigned an image to show, and sprites also keep track of multiple values about themselves, which will prove useful down the road when making animations. In order to create more interesting and detailed images, students are introduced to the sprite object.
