Detailed Description

class HBhvInterpolatorTrail : public HBhvInterpolatorPosition 

The HBhvInterpolatorTrail class draws a line trail from one keyframe position to the next.

HBhvInterpolatorTrail honors all modifiers from HBhvInterpolatorPosition.

Public Functions

HBhvInterpolatorTrail(HBhvAnimation *animation = 0, char const *name = 0)

Constructs an HBhvInterpolatorTrail object.

Parameters:

animation – The animation that this interpolator belongs to.
name – The name of the interpolator.

~HBhvInterpolatorTrail()

virtual char const *GetType()

Returns:: Type of the interpolator is ‘Trail’.

virtual HBhvInterpolator *CreateInstance(HBhvAnimation *ainst)

In special cases, you may want an interpolator that references this interpolator without changing it. Use this method to create the new interpolator passing a pointer to the animation that you want it to be associated with.

Parameters:: ainst – The animation instance that this interpolator is associated with.
Returns:: The newly created interpolator that references this interpolator.

virtual void Serialize(HUtilityXMLGenerator *xmlgen): Writes XML data to a buffer using the passed XML generator.

virtual void Interpolate(int keyframe, float fraction)

Performs an interpolation on the animation target.

Parameters:

keyframe – The reference keyframe for this interpolation.
fraction – The fraction value from the specified keyframe to the next keyframe. The value is from 0 to 1.

virtual void Reset(): Resets interpolator instance.

void Init(): Sets up the Trail

inline void SetTrailType(TrailInterpolatorType tt)

inline void SetTrailColor(char const *color)

inline void SetTrailWeight(int weight)

inline void SetTrailStyle(char const *style)

Public Static Functions

static void *XMLCallback(HUtilityXMLTag *xt, bool open, void *m_pExtraData): This is XML read callback which parses XML data and then populates the member variables with the associated values.
