This platforming base contains velocity, friction, jumping, gravity, wall jumping/sliding, maximum velocities, and is made to be easily customizable! It also includes a simple collision sensor for basic games, and an advanced sensor for more detailed collision sensing. All nearly completely glitch-free!

Please try it out, and tell me what you think (and feel free to use it for any game).
