Terrain Flow

I am being in a confusion and searching internet for a week, The Problem is i making 3d Semi top down camera game. What i want is how to make terrain, that explores and spawn objects as hero moves around. i mean how to trigger different terrain planes as my hero moves........or something like that..

 

Checking player position and spawning objects will be covered in the many tutorials in the Unity Learn area. Go there first.

General advice: Think of the absolute simplest solution and try that first. An example:

Terrain has a collider. Character controller has a collider. Colliders can be be set to trigger events. So you've got two colliders, then you need an event for spawning objects. And what calls the event? The two colliders colliding.

 

Thanks buddy
i got Idea....
