碰撞帮助，多个Class'继承 [英] Collision Help, multiple Class' with inheritance

问题描述

为了我的生命 我似乎无法弄清楚我做错了什么，我已经设法制造一个玩家并让它拍摄。还设法让敌人在图片框中以随机位置/速度生成。

for the life of me  i just cant seem to be working out what i am doing wrong, i have managed to make a player and make it shoot. also managed to make enemy spawn in at random locations/speeds in the picture box.

我似乎无法使任何碰撞工作，我试图将所有敌人都留在图片框中然后反弹并互相反弹，然后在射击时摧毁它们。

i just cant seem to get any Collision to work, i am trying to keep all enemies in the picture box and bounce back and also bounce off each other, and then destroy them when shot.

我一直试图使用  "Ball .Bounds.IntersectsWith（ pictureBox2.Bounds）"但似乎Ball.bounds是错误的。

i have been trying to use  "Ball.Bounds.IntersectsWith(pictureBox2.Bounds)" but it seems that Ball.bounds is wrong.

推荐答案

Ball没有属性边界。

Ball does not have a property bounds.
