How to make objects not pass through the trigger?

Question

Unity

I'm making a simple toy, I ran into a problem that the Player object passes through the Enemy object which is a trigger (this is necessary in order to handle bullet collisions), I don't need it, but I need a trigger. Prompt as it is possible to make that objects did not pass through the trigger?

Answer 1

You can check by tag, if an object with the "Player" tag collides with Enemy, then Enemy turns off isTriggered.

Answer 2

put a second trigger on Enemy.
