所以这就是发生了什么，游戏一直停止，因为两个圆圈相互碰撞，我试图通过确保ID是方形ID来防止这种情况，即时尝试让圆圈碰撞在一起只是忽略了碰撞，但没有做到这一点，我不知道如何阻止碰撞，只允许它与广场相撞。与精灵碰撞
基本上我想阻止圆与另一个圆碰撞，并允许它与广场相撞。
任何帮助将是巨大的谢谢
game.engine.engine类
//collision detection class
iter = p_group.listIterator();
Sprite spr = null;
while (iter.hasNext()) {
spr = (Sprite)iter.next();
//remove from list if flagged
if (!spr.getAlive()) {
iter.remove();
continue;
}
//is collision enabled for this sprite?
if (spr.getCollidable()) {
//has this sprite collided with anything?
if (spr.getCollided()) {
//is the target a valid object?
if (spr.getOffender() != null) {
/*
* External func call: notify game of collision
* (with validated offender)
*/
collision(spr);
//reset offender
spr.setOffender(null);
}
//reset collided state
spr.setCollided(false);
}
}
}
这是我为您在延伸game.engine.engine包中的游戏类碰撞。
