Title: I need some help, My bullet speed is too fast to detect collision.
Post by: wangcai on August 11, 2023, 02:40:18 AM

I need some help, I'm making a shooter game. When the bullet is flying very fast. rigid body often fail to detect collisions. How can I set them up so that bullets can still be detected when they are very fast.what do i need to do.I used Add Force to apply a force to the bullet,Or Translate was used to give the bullet a direction.I don't want to use raycast. I want the bullet to fly.Bullet has a trajectory.Excuse me, how can I make the bullet be detected when the speed is very fast.
Thank you all for your help, I used Google Translate. I don't know if you can understand it.

Hi
on rigid bodies you need to set the collision detection to 'Continious'
if the bullet is still passing through, try to increase the collider size.

You might need to use a raycast to do the hit detection.

with a raycast do the raycast first, then use the hit point to move to bullet to (for example with a tween position.
the bullet then does not need any collider (as the raycast is handling hit)

here is a raycast tutorial :
