OnTriggerEnter alternative which works with out physics system?

Unity Engine
1

  • I´ve got 10k+ object in my scene. Each object has a rigidbody (iskinematic) and a sphere collider on it. Object can be shot at.

  • Rigidbody collider are there only so i´m able to access it´s components via an external raycast/broadcastmessage.

  • For performance reasons, i´m trying to get rid of all rigidbodies/colliders but OnTriggerEnter/Raycast only to works with a collider.

  • Now i´m trying to find a way to access a specific gameObject´s component, with out relaying on the physics system.

Any ideas? Thanks in advance!
