Player movement laggy

Processing.py

Where I move player:

    def keyPressed(self):
        if keyPressed:
            if key == 'a' or key == 'A':
                self.state = "LEFT"
            elif key == 'd' or key == 'D':
                self.state = "RIGHT"
            else:
                self.state = "STOP"
    def move(self):
        if self.state =="RIGHT":
            self.vec.x = constrain(self.vec.x + 10,40,width - 40)
        elif self.state == "LEFT":
            self.vec.x = constrain(self.vec.x - 10 ,40,width - 40)
        self.state = "STOP"   
        


def draw():
    background(0)
    ball.show()
    paddle.show()
    paddle.keyPressed()
    paddle.move()
    ball.move()

eg I keep going left and when I change the direction to right the paddle continues going left for 1/2 secs.
Its because keyPressed() has a delay where it cant read any key?

Inspired by my old Java Mode “Player Move”: :coffee:

I’ve made a Python Mode version “Paddle Move”::snake:
