OnTriggerEnter conflict

Question

So I have a 2 Agents. Agent 1 is shooting at agent 2. The bullet is a trigger and the agent has a collider. I have a bulletController script and a AgentController.

My problem:

If one agent hits the other with a bullet I get NullReferenceException, because in the agents script I have a OnTriggerEnter and I look there if the bullet hits. But the agent doesn't have a trigger. So would it work if I set the method to onCollisionEnter, even if the bullet is a trigger? How can I solve this? But I do not want to place the Ontriggerenter to the bullet script.

Hello!

You are little bit copnfused :D (its normal collides are confusing sometimes)

First, i recommend you to spend 30 minutes reading the Unity Manuals

https://docs.unity3d.com/ScriptReference/Collider.OnTriggerEnter.html

And all its variants (enter, stay, exit, trigger, collision....)

I'm sure you will find some sentence that will make you realize something you didnt know or didnt understood.

Then, i think best solution is to make the bullet a trigger collider, and only detect from inside the bullet if the triigerEnters some collider with tag enemy or player or something like this.

Bye!
