Creating 2D screen loopback more efficiently

lambchop

So I'm doing the "Your first game" tutorial and I wanted to create loopback for the player. So like if they went off one side they appeared on the other side. My problem is I don't really know how to use modulo so I created an if statement. Is there a way I could use mod to make this cleaner

position.x = fmod(position.x, screen_size.x)
position.y = fmod(position.y, screen_size.y)
if position.x < 0:
	position.x = screen_size.x
if position.y < 0:
	position.y = screen_size.y

Don't understand modulus in general?

https://en.wikipedia.org/wiki/Modular_arithmetic

or just fmod(), fposmod() for floats(Real numbers) in GDScript?

https://docs.godotengine.org/en/stable/classes/class@gdscript.html#class-gdscript-method-fmod https://docs.godotengine.org/en/stable/classes/class@gdscript.html#class-gdscript-method-fposmod

Note that what you get back out of there is the remainder of your input values.

You'll basically want to keep a reference value of level bounds/size and use that in your modulus together with player position.
