Thank you. I’m a beginner so learning to simplify code will be really good.

I tried placing it self.update, but then it wouldn’t work.

width, height = ui.get_screen_size()
I think this is right. I did a seperate script where I print it out inside the console, and it worked.

Only the wrapping.

Here you go:

def handle_button_presses(self):
        rotationAdd = math.pi/180
        self.Player.location = self.Player.position
        for touch in self.touches.values():
            if touch.location in self.LeftCrtl.bbox:
                actions = [A.rotate_by(math.pi/180)]
                self.Player.rotation = self.Player.rotation + rotationAdd
                self.Player.run_action(A.sequence(actions))
                
            if touch.location in self.RightCrtl.bbox:
                actions = [A.rotate_by(math.pi/-180)]
                self.Player.rotation = self.Player.rotation - rotationAdd
                self.Player.run_action(A.sequence(actions))
                

            if touch.location in self.UpCrtl.bbox:
                direction = Vector2(-math.sin(self.Player.rotation), math.cos(self.Player.rotation))
                self.Player.position += direction*3
                if self.Player.position.x <= 0 or self.Player.position.x >= 1112:
                    self.Player.position.x %= width
                if self.Player.position.y <= 0 or self.Player.position.y >= 834:
                    self.Player.position.y %= height

I did change the movement code a little.

Whenever the Players position.x is equal to or smaller than 0 or whenever the position.x is equal to or greater than 1112, you do the remainder of the division of the screen height.

I have added this:
width, height = ui.get_screen_size()
And then added this later:
if self.Player.position.x <= 0 or self.Player.position.x >= 1112:
self.Player.position.x %= width
if self.Player.position.y <= 0 or self.Player.position.y >= 834:
self.Player.position.y %= height
This didn’t work. I checked if I had gotten the width and height variables in a seperate script, and I did. I am now stumped.

@cvp And what about location?

Wait, how do find the screen width and height? And what about location?

Oh, thanks.
