Hello there i’m currently working on a project where i want to detect collision with 2 box colliders and perform an action on the if statement.

Can someone help me?

Whats the code showing? You can just implement onCollisionEnter on a component that is on the box collider.

There are some samples in here using that (for e.g. changing the color on collision: GitHub - needle-tools/needle-engine-samples: Live: https://engine.needle.tools/samples 🌵 Needle Engine sample scenes - use as examples and as a reference for learning 😊)

That’s a callback function and invoked by the physics engine

you dont invoke it with a box collider component
