Question by ffff1111 · Dec 04, 2012 at 02:55 AM · raycasttriggerperformancefaster

Which is faster? Raycast or trigger?

I need to check if ONLY ONE SIDE of a mesh touches any collider.

So, what would be faster?:

  • A raycast with hitInfo, very short distance and layermask.

  • A raycast without hitInfo and very short distance.

  • A sphere trigger with OntriggerEnter with colliderInfo.

  • A sphere collider with OnCollisionEnter without collisionInfo.

I read sphere triggers have very good performance...but are they faster than a simple raycast?

Setting a short distance on a raycast (compared to infinite) does give a large speed-up. Could also use a spherecast to get the same shape as the sphere trigger would have been.

Raycast: if your character's gravity more then 15 down Raycast not work properly ...

Trigger: While your character in trigger it work good...

Raycast is batter when you are not use for gravity, raycast tell you coming things at front/back/up/down etc.. but trigger you know by the time it not work while it not collide others..

hope this is helpful.
