Source Engine Movement in Unity

A minimalist extension to Unity's Character Controller that enables Source and Quake style movement, such as bhopping and surfing.

This character controller only works properly with the new input system.

Features supported by this character controller:

• Bunny hopping
• Surfing
• Quake and Source/GoldSrc style velocity calculations
• Step offset
• Ladders

Features not supported by this character controller (for now):

• Water movement
• Ladder movement strats
• GoldSrc movement strats such as MCJ

Setup

Create an instance of MoveVars

1. Under Assets/Resources, right click > Create > Scriptable Objects > MoveVars.

3. Now you can tweak and test out different values for the movement variables in the editor using this MoveVars asset.

Input System Setup

1. Make sure the new Input System Package is installed.
