body.isBullet
Description:
A boolean for whether the body should be treated as a “bullet”. Bullets are subject to continuous collision detection, rather than periodic collision detection at world timesteps. This is more computationally expensive, but it prevents fast-moving objects from passing through solid barriers. The default is false.
一個布爾該機構是否應被視為一個“子彈頭”。子彈都受到連續碰撞檢測,碰撞檢測,而不是定期在世界時間步。這是更昂貴的計算,但它可以防止快速移動的物體從穿過堅實屏障。默認為 false。
在body碰撞判斷時,如果速度很的碰撞,會有無法判斷碰撞的現象發生,如果把body.isBullet設定為true,那就可以很精密的判斷碰判,這可能會降低效能,因為cpu一直在計算。
