Show_message(string(example)) //output: 3 We can obtain the value at any time: var example = states.attack Note that we don’t have to explicitly set the value of each entry the enum automatically assigns the value 0 to “normal” and increments each entry after that. I prefer using enums as they are much easier to manage and to keep track of than Macros.Ĭreate a script and name it enum_init. If you are familiar with Macros in GameMaker, enums are sort of like that. The easiest way to do this is with an enum (short for Enumeration), which is a collection of constants held under a custom variable type. Since this example is all about character actions, let’s define what those actions are and give each one an integer id. In order to set up our state machine, we first decide which states will be possible and how we’ll identify them in our code. Make sure the origin of each sprite is (16, 32). Go ahead and add all of the sprites-even the enemy sprites-since we’ll need those in a later blog entry. I’ve named the files appropriately, so just make sure the name of the sprite matches the name of the file once you’ve added it to GameMaker.

Download the sprites from this link and add them to your project. This entry requires a few more animations than the previous entry, so before we get started you will want to add those to your project. Note that even though this example uses GameMaker and some GameMaker-specific code, state machines can be used in any dev environment. In this article, we’ll use a state machine to control what player actions are available at any given time, allowing us to set up a character and define what that character can do. It’s up to us to define the states that make sense for our situation, and the relationships between them.

For example, our game may have three states: “Game Running,” “Game Paused,” and “Game Over.” We might use a state machine to remember which one is active, and define how to transition from one to another (see image above).īy design, state machines can only ever be in one state at a time. A state machine is a data structure that, as the name implies, keeps track of different states. Today I want to show you how to set up a simple state machine. If you are following along from the previous entry, great! We will be picking up right where we left off.

Otherwise it will run the function from the calling scope, which will not result in a new struct being created.Hello everyone and welcome to the second entry in this series on GameMaker basics. This is because GML needs to know to transfer the scope over to the new struct that is being created. You can call a constructor function without “new” but it will not return a struct. However, this also means GML needs to know that this function is expected to return a struct, which makes use of the “new” keyword. All the variables and logic we run takes place in the newly created struct. It may be easiest to think of it like the create event for an object. What this means is they behave like a function, allowing us to call other functions, perform logical operations, and assign variables as expected, but upon completion will return a struct. Since all scripts get updated to use this format, we should take a look at the new function syntax: function subtract( a, b ) Ĭonstructors are functions that return structs.
In short, what we traditionally think of as a “script”: a function we can call from anywhere in the program. I will not delve into the technical specifics here, but a script function is just a method defined to a global scope that reserves its name. However, I should clarify a couple of details before we start: first the difference between a script function and a method.

They can now contain any number of script functions, methods, or code to run before the game starts! Scripts still contain code, but are no longer limited to a single function per script. GML 2.3 now distinguishes between a “script” as a resource, and the new method/script function. Script Functions/Methodsįor users familiar with GML, one of the first, and most noticeable, changes in 2.3 will be to “scripts.” He enjoys coding, playing video games, and answering code and design-related questions. Guest written by Devon Mullane, aka Hyomoto, who you can find on the Game M aker Helpers Discord. In this post, we’re going to have an in-depth look at all the new GML features, from script functions/methods to structs and try-catch blocks. GameMaker Studio 2.3 came out recently, with a lot of updates ranging from an animation editor, to new GML features.
