## rex_physics_speedclamp

**Upper or lower bound**

Set upper bound and lower bound of speed in properties table "Upper bound", "Lower bound", or set by "Action:Set upper bound", "Action:Set lower bound".

Read back these values by "Expression:UpperBound" or "Expression:LowerBound".

**Speed clamp**

Speed will be clamped in a range if upper bound is not equal to lower bound. In this case, "Condition:On hit upper bound" or "Condition:On hit lower bound" will be triggered while current speed is larger than upper bound, or smaller than lower bound.

If upper bound is equal to lower bound, speed will be fixed in upper bound, no triggered event will be fired.

Get current speed by "Expression:CurSpeed".

**Activated**

Set property "Activated" to "No", or set by "Action:Set activated" to disable this behavior.
