Having Multiple Colliders do diffrent things

Hello,

i have a GameObeject (Enemy) with 2 Colliders. When the Player enters/leaves Collider 1 it should do sth. and when the Player enters/leaves Collider 2 it should to sth. different.

is there a way to tell OnTriggerEnter2D on what collider it should execute?

yes, but only if you attach them to different game objects.That should not be an issue, since you can create as many children game objects as you like.
