Effects

Effects are cool visuals that may be generated at the end of a SENT, when firing a SWEP, and/or when using a tool. Team Garry has created one very unique example, of the wheel. He made a custom material, and then used scripts to flip, rotate, and set rotation loops of this. they are generated by the wheel entities created by the wheel tool.
