Basic Collision, Object + First Person

Questions & Answers
1

Alright, So I have a door that I’ve made in blender and I want the character to stop when it hits it, I.E not have the ability to pass through, I have a whole town and map set up that I’ve created in blender and I can walk through all of it. If I add box-colliders the objects just dissapear, I’ve also set them all to gameObjects. If anyone is going to direct me towards scripting I understand C# the most, although I can convert from javascript. I just want basic collision and I’m not understanding how to get it. I’m not looking for some high-grade physics, but not walking through houses/walls would be nice. Having a script for opening and unlocking doors is useless if you just pass through them.

EDIT: I’ve set mesh coliders and rigidbodies, but still nothing. I just walk straight through.

When importing your models Unity offer an option to “Generate Colliders”. Enable that and check what happens.
Also don’t forget to hit “Apply” at the bottom of the menu

I’m just getting back into Unity, so take this answer with a grain of salt, but can’t you convert your whole level mesh into a big collision mesh? Then you’ll collide with all of it…
