Player on trigger not working!

jamesfootlight

Hi,

I have been through all similar forum posts but nothing seems to help me understand why my triggers are not working.

PLAN: to have a camera switch to another camera that is zoomed in closer to the player when the player walks through a trigger in the scene.

PROBLEM: nothing happens when the player walks through the trigger

I can attach screen shots of the scene, the player, trigger and camera inspector if it helps

Thanks!

The most common cause of this problem is that the player doesn't have a Rigidbody / Rigidbody 2D component attached.  Check that this is the case, and post screenshots of Player's Inspector if that doesn't help.

Thanks, will give it a shot. Would this be on the child or root?

On the root - you can always look to the demo player characters for reference.

Hi, player root has a rigidbody, but the camera is still not being triggered?

I have sorted this, my player did not have a box collider 2d on it!

Thanks!

The screenshots don't show a rigidbody on the root - only the sprite child.  "Is Kinematic" will likely need to be left unchecked, too.

To dismiss any red herrings, temporarily change the Trigger's Action to an "Action: End game".  That will cause the game to exit as soon as the trigger occurs.

Hi, when i remove the 'Is Kinematic' checkbox, strange things happen with gravity.... my player falls through the floor. it is working with the is Kinematic check ticked, but what i have trouble with now is that my triggers do not seem to cover the whole path in front of the player and the player has to be to specific to find/touch the trigger, i have tried expanding the size and scale of the trigger but that doesn't seem to do anything - any ideas?

Thanks

You'll have to post visuals to explain what you mean.  The Trigger has to connect with the Player's collider.

Hi, please see screenshots in link below:

My player should instantly turn and run and the seaguill should animate when entering the trigger, but as you can see from the in play shot, I am standing next to the seagull and nothing has happened. I want my player to run away the second he is in the area, my trigger is on continuous, and I have tried it on On Enter too. The box collider on my player is on the root.

Did you link to the wrong screenshots?  I don't see a trigger nor a seagull.

Sorry!

The trigger area seems to be to small on the horizontal plane, and the player has to be so specific to get the trigger to work, stretching the trigger area has not helped.

Does your Player prefab have a circle collider at his base?  "Is Trigger?" should be unchecked - this is separate to the box collider around his whole body.

Alternatively, try removing the BoxCollider2D from the Trigger itself, and replace with a PolygonCollider2D.  Reset the Trigger's scale, and position the nodes of the polygon collider exactly how you want it - does that make a difference?

It was the circle collider, added it and worked like a charm, thanks!
