為什么我的播放器在跳躍后不下來?

[英]Why is my player not coming down after jumping?

我目前正在嘗試編寫我的第一個 GUI 游戲,其中玩家從一個障礙跳到另一個障礙。 當按下空格鍵時,玩家應該做一個簡單的跳躍(實際上並沒有在 x 軸上移動),但是當按下空格鍵時,玩家只會上升而不會下降。

這是我的代碼中的變量:

private int playerY = 415, playerX = 100, score=0, maxHeight = 350;
private float speed=3, jumpStrength, weight=1;

這是我讓玩家跳躍的代碼:

    public void keyPressed(KeyEvent e) {
    int key = e.getKeyCode();

    if (key == KeyEvent.VK_SPACE && playerY>=maxHeight) {
        jumpStrength = 24;
        playerY -= jumpStrength;
        jumpStrength -= weight;
    }
    if (playerY>=maxHeight){
        playerY = maxHeight;
    }
}

public void keyTyped( KeyEvent e )   {}

public void keyReleased( KeyEvent e ){}

有沒有人知道為什么它不起作用以及我如何解決它?

我不知道你的其余代碼看起來如何或你的游戲如何工作,但這是我的一個想法。

public void keyPressed(KeyEvent e) {
    int key = e.getKeyCode();

    if (key == KeyEvent.VK_SPACE) {
        jumpStrength = 24;
        jumpStrength += weight;
        playerY -= jumpStrength;
    }
    if (playerY>=maxHeight){
        playerY = maxHeight;
    }
}

public void keyTyped( KeyEvent e )   {}

public void keyReleased( KeyEvent e ){
    int key = e.getKeyCode();
    if (key == KeyEvent.VK_SPACE) {
        jumpStrength = 24;
        jumpStrength += weight;
        playerY -= jumpStrength;
    }
    if (playerY<=0){
        playerY = 0;
    }
}
