|
||||
General purpose area detection for 3D physics. Areas can be used for detection of objects that enter/exit them, as well as overriding space parameters (changing gravity, damping, etc). For this, use any space override different from AREA_SPACE_OVERRIDE_DISABLE and point gravity at the center of mass.

Set the rate at which objects stop spinning in this area, if there are not any other forces making it spin. The value is a fraction of its current speed, lost per second. Thus, a value of 1.0 should mean stopping immediately, and 0.0 means the object never stops.
|
||||
In practice, as the fraction of speed lost gets smaller with each frame, a value of 1.0 does not mean the object will stop in exactly one second. Only when the physics calculations are done at 1 frame per second, it does stop in a second.

Set the order in which the area is processed. Greater values mean the area gets processed first. This is useful for areas which have an space override different from AREA_SPACE_OVERRIDE_DISABLED or AREA_SPACE_OVERRIDE_COMBINE, as they replace values, and are thus order-dependent.
|

Areas with the same priority value get evaluated in an unpredictable order, and should be differentiated if evaluation order is to be important.

A contact is detected if object A is in any of the layers that object B scans, or object B is in any layer scanned by object A.
