Is game maker drag and drop good?
Drag and drop can be a good starting point, but you’ll quickly find that as you become more knowledgeable about GameMaker it’ll be faster and easier to just write gml code. They work just fine together. You don’t even have to pick one over the other, you can use them together as well.
How do you code gravity in Game Maker?

What does VAR do in GML?
Like any programming language GML uses variables as the basic unit for most programming operations. Variables are used to store information in the devices memory for later (or instant) use, and they are given a name so that you can refer to them in runtime and script functions.
When to use global variable in GameMaker Studio?
So GameMaker: Studio will create the variable, use it for the duration of the event and then “forget” it again, meaning that if you try to use it later you will get an “unknown variable” error. global: a global variable is one that belongs to the game world itself and not to any one instance.
Do you have to declare global variables in YoYo Games?
Just like local variables, global variables must be declared, but unlike a local variable, a global variable remains in memory until the end of the game. So, you can create a global variable to keep track of (for example) the number of bullets that the player has and then just update this variable at different points in the game.
How is a global variable different from a local variable?
A basic description of a global variable is one that, once declared, belongs to no instance in particular and yet can be accessed by all. Just like local variables, global variables must be declared, but unlike a local variable, a global variable remains in memory until the end of the game.
What is the definition of a variable in GML?
A variable in GML can store either a real number (like 100, 2.456575, -56 etc…) or a string (like “Hello world!”). A variable is something that we use to store a value for use in one or more operations or functions. Think of “pi”, for example… it is a real world variable that holds the value 3.14159265(etc…).
