Member Function Documentation

void vtFlyer::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 vtEngine.

float vtFlyer::GetSpeed ( )

inline

Get the speed of navigation. This is the speed at which the target will more at maximum mouse displacement.

void vtFlyer::SetSpeed ( float fSpeed )

inline

Set the speed of navigation, in meters per second, at maximum mouse displacement.
