problem - collision with trees ?

Hi I'm new with unity .

I'm trying to make a shooter game , so I use the terrain map then I put some trees and rocks , but the problem that I across the trees . is there away to stop the player when it collide with the trees

notes : The "Create tree collides" is enable

thanks

Yea, that little check box doesn't do anything I've found...

What you're going to have to do is get the prefab of the tree, make a duplicate, then add a collider to it, then use THAT model for the tree...

Setting up Tree Collisions

If you'd like your trees to make use of colliders, it's very easy. When you've imported your Tree asset file, all you need to do is instantiate it in the Scene View, add a Capsule Collider and tweak it, and make the GameObject into a new Prefab. Then when you're adding trees to your Terrain, you add the tree Prefab with the Capsule Collider attached. You can only use Capsule Colliders when adding collisions with trees.

Good luck!

I create a separate scene for doing this. That is, create a new scene and place all of your trees, bushes, etc. in there (evenly spaced) so you can work on them individually. As long as they are Prefabs then anything you do to them and apply will be available throughout your project.

Doing this de-clutters you game scene and gives you an uncluttered scene (that will not be part of the game build) where you can tweak and adjust your terrain elements. I have additional scenes for building, props, characters, etc.
