Auto-disable hints | |
The reason for auto-disable override hints is that some geoms need different parameters.
For exemple, when the body has remained a disable candidate for a certain number of steps (AutoDisableSteps), it is disabled. This is almost completely for boxes, which like to land and bounce up on two points, and teeter motionless for a few steps before falling back down. Round items generally need a much lower (like 1) AutoDisableSteps than boxes do (10+), 10 is the default. | |
| virtual UINT | getADOverrideFlag () |
| Gets the auto-disable override flag (default is no override - can be overloaded in derivates). The method returns which parameters can be overriden by the geometry. | |
| virtual bool | getADFlag () |
Returns true if the geometry can be auto-disabled. | |

Detailed Description
Abstract class for creation and manipulation of physical geometries (Spheres, boxes, etc.) Geometry handlers are responsible for the geom creation (create() method), not their destruction ! They're a kind of factory. They also contain hints for body auto-disable feature (when a geom is attached to a body).

Constructor & Destructor Documentation
| Physics::GeometryHandler::GeometryHandler | ( | ) | [inline] |
Definition at line 90 of file GeometryHandlers.h.
| virtual Physics::GeometryHandler::~GeometryHandler | ( | ) | [inline, protected, virtual] |
Protected destructor forces the object to be deleted by being dereferenced.
Also avoids the object from beeing created on the stack.
