Detailed Description

Similar to vtTerrainFlyer, but a velocity (with damping) is maintained. Viewpoint moves even after mouse button is released.

Member Function Documentation

void VFlyer::Eval ( )

virtual

Virtual handler, will be called every frame to do the work of the engine. You must override this if you want your engine to be useful.

Reimplemented from vtTerrainFlyer.

void VFlyer::SetDamping ( float  factor )

inline

Set the damping of the velocity, per second. A typical range is from 1 (very little damping) to 10 (a lot of damping).

void VFlyer::SetGravity ( float  grav )

inline

Set the downward acceleration, in meter per second squared. For example, a value of 9.81 would be normal gravity at the earth's surface.

void VFlyer::SetGroundTester ( vtHeightConstrain *  pEng )

inline

In order for gravity to cease when the target is prevented from falling, e.g. when it is sitting on the ground, supply the engine you are using to keep the target above the ground.
