Preventing player from going through walls (maze)?

Hi,
first of all, I didn't know where exactly to put this thread but I figured it has something to do with scripting.

i built a maze in cinema 4d and unified every wall into one game object. So the whole maze is now one object.

I imported it into unity and i don't want my character to walk through the walls. This worked the first time through fixedUpdate while putting BoxColliders on individual Walls. But now I got this biiig maze and using a boxcollider is not possible now.

I was thinking of using an if-method kinda like this. So it looks if it touches a wall and then doesn't move farther but this would require the maze to have a collider, right?

if(collision.gameObject.CompareTag("Walls"))
{
....
}

I'm now thinking of putting a box collider on every single wall but this would take forever. Is there a simpler method?

Sry I'm new to scripting and unity and I'm feeling a little lost.

 

There's lots of different kinds of colliders in Unity. One you have discovered is BoxCollider.

Another is MeshCollider, which lets you use any arbitrarily shaped mesh as a collider, as its name would imply.

Have you tried just adding a MeshCollider to your maze object in the scene? It might just work.

Also, for this:

You MUST spell and capitalize these words correctly, otherwise Unity doesn't know them.

The correct capitalization in this case is

FixedUpdate()

If you ever doubt the capitalization, go STRAIGHT to the documentation.

 

Ahh it worked! Thank you!
Yes I did look out for correct spelling, I just didn't write it correctly in this thread.
