The collision of game objects are often fail and occasionally success

Questions & Answers

In my project, The collision of game objects are often fail but occasionally success.

I did some research which tells that if game objects move too fast, or the game object is too small, this will happen.
The solution is to set “collision detection” of Rigidbody to “Continuous Dynamic”, set a slower moving speed, and set the game object bigger.

I have done all of these, I believe my game objects are not too small and fast, but it still happen. What could I do?

(I did try to slow my bullet’s moving speed to “5” and the collision success rate is higher, but still not 100%. )

Hi @EZ_Sherab, in your video it looks to me like all the objects your bullets hit are getting destroyed. It is hard to tell from your video, but looks like all of your objects are not falling in the same plane, and yes, some of the smaller ones are missed because of that - they are slightly off to the side. And some of the smaller ones are pretty small… but other than those issues, if they are true, try the Continuous Speculative mode, and make sure your bullet and bubble’s colliders are aligned to their meshes the way you think they should be.
