Make Bullet prefab ignore 1 collider

Hello guys ,i am new to Unity , i was trying to make my Enemy AI with a trigger Collider to follow the player when the player in the trigger zone , but the problem is my bullets now effected by this trigger zone also , so how do i ignore this trigger zone so my bullet can hit the enemy
I tried to set the collider enable = false when ever the player press "LeftMouse" but it was not good enough,
u guys have any suggestions ? thanks.

 

good question

 

You need to put your bullet and your trigger zone in different layers. See the right side of the screenshot below where you can set the layer.
Make sure that in the PlayerSettings your two layers unchecked, so they don't affect each other. (see the settings portion of the screen shot). Be careful, you will need to set up in a way when the bullet still can collide with the other colliders.

Thank you so much , follow your instruction i created another gameobject and put my enemy object in it so i can put the trigger collider to the gameobject and have the layer different with the children (Enemy) object and it worked
