i have two almost identical game objects but my trigger collider only picks up collisions with one of them. Any ideas about why this is happening?
The trigger collider is a circle collider 2d
The two objects have circle colliders2d and rigid bodies.
Is only fist one collected or just one type ? Did you checked name or tag from other ?
Please provide some useful information rather than just a vague description. You should try to provide at least the script that is handling the callback so we can see any potential logic errors.
