libgdx，如何检查随机生成的actor的冲突？

Question

I have two groups of randomly generated actors, one is bullets second is enemies. And as of now I have no idea how to check collision of randomly genrated actors and remove the overlaped actors. I'm newby.

At least provide some pseudocode! Thanx in advance!!!

Answer 1

1. Using a physics engine

   Libgdx has built-in support for following.

   1. Box2d for 2D physics
   2. Bullet for 3D physics.

   
   Physics engine can handle collision detection and you can provide callbacks to specify what to do when a collision occurs.
   
   You can find many tutorials on the internet.

2. Implement collision yourself

   It is a bit work but may be suitable for small applications.

   1. You will have to perform an^2 intersection check for all objects in each frame.
   2. For this, you will have to write intersection test logic for all your shape pairs.
   3. Then you can deal with detected collisions as per your wish.

Hope this helps.
Good luck.
