获取其他车辆位置

[izvvv]

如果我随机放置障碍物，为了防止障碍物与其他车辆重合，我想要用预防碰撞一样方法来解决，则需要获取其他车辆的位置，请问我应该怎么做？

If I place an obstacle at random, and I want to solve it in the same way as collision prevention in order to prevent the obstacle from colliding with other vehicles, I need to get the position of the other vehicle, what should I do?

I've found a solution, but there's a problem with it. When I run the running code, I get an error like this, but sometimes it works successfully and doesn't seem to be regular.

it's because you've found a collision at index i, so you remove obstacle x from the list, but you dont break out of the loop, so at index i+1 you may try to remove the obstacle x from the road objects again when it has been removed already. I think just adding a break statement after the a+=1 would be fine.
