Meu oponente ou nunca erra ou nunca acerta, dependendo da subtração.

Meu oponente nunca erra a bolinha quando uso a função dessa forma:

function movePaddle1(){
  speedPaddle1 = yBall - yPaddle1 - hPaddle1 / 2 - 50;
  yPaddle1 += speedPaddle1
}

Se eu aumento o valor para "2 - 55", ai ele nunca mais acerta a bolinha.
