如何使用C＃和XNA進行雙跳？

Question

這是我目前單跳的代碼，來自用戶的輸入設置跳轉為true並且單跳轉沒有錯誤，但是我不能為我的游戲產生第二次空中跳躍。 我不得不在沒有團結的情況下這樣做，所以它只適用於矩形。

if (jumping) //only run when jump has been initiated by space or A
{
    rect.Y = centreY - (int)(Math.Sin(angle) * range); //move player up to a maximum of range's value

    angle += speedY; //gradually reduce player's y by reducing angle's value

    newCentreY = rect.Y;

    if (angle > Math.PI) //reset player to not jumping when angle is greater than 3.14
    {
        angle = 0;
        jumping = false;
    }
}

這是跳轉的輸入處理程序：

if (userControl.Buttons.A == ButtonState.Pressed || keystate.IsKeyDown(Keys.Space)) //jump when A or space is pressed 
{ 
    jumping = true; 
} 
Jump(userControl, keystate); //jump method

我認為你應該讓你的angle為0才能繼續跳躍。

if (doubleJumping)
{
    angle = 0;
    doubleJumping = false;
}
if (jumping) //only run when jump has been initiated by space or A
{
    rect.Y = centreY - (int)(Math.Sin(angle) * range); //move player up to a maximum of range's value

    angle += speedY; //gradually reduce player's y by reducing angle's value

    newCentreY = rect.Y;

    if (angle > Math.PI) //reset player to not jumping when angle is greater than 3.14
    {
        angle = 0;
        jumping = false;
    }
 }
