Angled Walls Allow Clipping/ Jitter

As displayed in the following video when I set up walls at angles and collide into them (player movement excerpt)

Code (CSharp):

1. float h = Input.GetAxis("Horizontal")/drag;
2.         float v = Input.GetAxis("Vertical")/drag;
3.         transform.Translate(h,0,v);

I am able to clip right through.
Do i need to revert to a velocity driven system?

 

Modifying the player's transform overrides any physics or collisions. I'm not expert here, but I think you should use the available components and scripts in Unity for controlling the character.

 

That means you bypass the physics engine and "teleport" the object from its viewpoint.

You need MovePosition() instead. https://docs.unity3d.com/ScriptReference/Rigidbody.MovePosition.html

Also check if your objects even have colliders as well as rigidbodies. (colliders are definitely needed, rigidbody depends on what you actually want to do)

 

Rigidbody.MovePosition also bypass the physics engine. The difference with modifying transform.position is that MovePosition applies interpolation for displaying intermediate steps.

Without having experience here, it seems that using a CharacterController component and its Move or SimpleMove methods is a better approach for this case. From:
https://docs.unity3d.com/ScriptReference/CharacterController.html

"A CharacterController allows you to easily do movement constrained by collisions without having to deal with a rigidbody."
