Local variables are temporary storage that improves performance and readability. Compare these two blocks:
Runs once when the object is born (use for setting variables).
gravity / gravity_direction : Automatic acceleration downward or toward an angle. Custom Grid-Aligned Movement (Recommended)
// Create event shake_magnitude = 0;
Do not place heavy calculations in the Step event if they don't need to run every frame.
// Direct coordinates x += 5; // Move right y -= 4; // Move up
// Scopes global.playerScore = 0; // Global variable (accessible anywhere) local_temp = 5; // Local variable (only in this event) instance.damage = 20; // Instance variable gamemaker studio 2 gml
If you are just starting out with GameMaker Studio 2 and GML, what specific type of game (e.g., RPG, platformer) are you hoping to create? Knowing this, I can provide more tailored examples or point you toward helpful, specific resources.
GML uses standard programming structures to control code flow.
Curiosity getting the better of her, Elara whispered a forbidden script: instance_create_layer(x, y, "Instances", obj_ancient_one); . GML uses standard programming structures to control code

Complex logic, state machines, and mathematical algorithms are easier to implement in text.
