Question: How many global variables can you have in GameMaker?


In GameMaker, there isn't a predefined limit to the number of global variables you can use. However, it's important to manage them effectively as excessive use of global variables can lead to code that is hard to maintain and debug.

Global variables are accessible from anywhere in the game, which means they can be modified by any part of the code, potentially leading to unpredictable behavior if not managed carefully.

Here's how you might define a global variable in GameMaker:

global.myVariable = 0;

And here's how you would access or modify it anywhere else in your code:

// To access var value = global.myVariable; // To modify global.myVariable = 100;

Best practices suggest using global variables sparingly and considering alternative approaches such as instance variables, local variables, or data structures that better encapsulate your game's state.
