Speed Zone
"Speed Zone" is the internal name for areas which boost your slide while doing an on-foot manual.
The Speed Zone can be scaled to any size. Team Reptile uses multiple speed zones of differing sizes to build curves and corners.
Speed Zones are a trigger volume, so they are invisible in-game, unless you use the Debug UI to make them visible. They should be paired with art or level geometry so the player understands where they can slide.
