품목 픽업을위한 카운트 다운?

Question

내 폭탄 범이 아이템을 가져 오면 좋겠다. 그러나이 항목은 5 초 동안 만 작동합니다. 따라서 부울 collisionWithTiles 메서드에서 카운트 다운과 같은 것이 필요합니다.

제안 사항?

우리는

protected boolean collisionWithTile(int x, int y) 
{  
    neueZeit = System.currentTimeMillis(); 
    differenzZeit = (int) ((neueZeit - alteZeit)/1000f); 

    // Prüft ob der Stein vorhanden ist und ob eine kollision mit dem Tile 
    // Star besteht 
    if (handler.getWorld().getTile(x, y) == Tile.star && Stone.isStone == false) 
    { 
     alteZeit = System.currentTimeMillis(); 

     handler.getWorld().setTile(x, y, Tile.grassTile); 
     return false; 
    } 

    if(differenzZeit <= dauer) 
    { 
     this.speed = (float)speedboot;//speedboost hat die geschwindigkeit von 0.7f statt 0.3f 
    } 
    else 
    { 
     this.speed = DEFAULT_SPEED; 
    } 
    return handler.getWorld().getTile(x, y).isSolid(); 
}
