OnTriggerEvent doesn't detect some objects

Question

I have object (ball) that is prefab initialized on game start. On that prefab i have Script, Mesh renderer and Sphere collider. Now when i cast my Spell, it is normally colliding with me and OnTriggerEvent detect character (me) but not the ball. Why is that?

If you need any part of code or something ask me.

Answer 1

For Trigger, you have to keep in mind this table

Ensure that isTriggerEnter is checked on ball. ref

Answer 2

maybe your ball is on a different layer that does not collide with your default layer? check your layer settings
