Collision Sliding

I’m currently working on a simple FPS engine and I must say I’m quite proud of it, but I’m having a problem with the collision. When I go against a wall and let go of the forward button, I slide away from the wall. I tried increasing the mass of the cube that is used as the body, but it didn’t do anything.

Extra Question:How would you go about making a fade in or fade out effect?

Change the friction of your object to 7.5

Go to Shading (F5)
Add a material if needed
On the “Material” Menu at the bottom there is a tab called “DYN”
Click on that and change the friction from .5 to 7.5 or higher
