njDrawMotionLink

Links motions

FORMAT

void njDrawMotionLink( *object, *motionlink, frame )
NJS_OBJECT *object
NJS_MOTION_LINK *motionlink
Float frame

PARAMETER

 *object  Pointer to object structure 
 *motionlink  Pointer to motion link structure 
 frame  Frame number (from 0 to 1) 

RETURN

None

DESCRIPTION

Links two motion structures.

The motion link structure contains two motion frames, from the link source and link target. When the parameter frame is 0, the motion is of the source frame, and when it is 1, the motion is of the link target frame. Other frames (0 < ff < 1) are interpolated.


EXAMPLE

#include <Shinobi.h>
#define	OBJECT	object_sample
#define	MOTION1	motion_sample1 /* Entered in NAM file */
#define	MOTION2	motion_sample2 /* Entered in NAM file */
#define	STEPS	60
extern NJS_MOTION	MOTION1[];
extern NJS_MOTION	MOTION2[];
NJS_MOTION_LINK	motionlink;
	:
motionlink.motion[0] = MOTION1;/* Link source */
motionlink.motion[1] = MOTION2;/* Link target */
/* Interpolate from last frame of MOTION1 to 1.5 frames of MOTION2 */
motionlink.frame[0] = MOTION1->nbFrame-1;
motionlink.frame[1] = 1.5;
	:
njDrawMotionLink( OBJECT, &motionlink, ff/STEPS ); /* Frame specifies 0 - 1 */
ff+=0.2f;
if( ff >= STEPS - 1 ) ff=0.f;
	:

NOTE

The drawing performed by this function is identical to model drawing, except that motion has been added. In other words, all of the njControl3D() settings are identical. This function corresponds to the model drawing function njDrawObject(), so the light source is normal light.
