The Hover-Ball is a tool in Garry's Mod. It is used to create a ball which can be attached to most props. These balls have configurable keys in the menu which, when pressed, make the ball (and as such the object) move up or down. They are commonly used to create a hovercraft of some sort. Hover-Balls have adjustable;
- Strength which defines how much weight a hoverball can hold
- Speed which defines how fast the hoverball moves up and down
- Air Resistance which defines how fast the hoverball will slow down once the key has been un-pressed
Hover-Balls will attempt to stay at the height specified, and if knocked away will immediatly pull the object back up to the desired height.
