Ninja Library - Motion Function

njCnkSimpleDrawShapeMotion

Executes motion with shape

FORMAT

void njCnkSimpleShapeDrawMotion( *object, *motion, *shape, frame )
NJS_CNK_OBJECT *object
NJS_MOTION *motion
NJS_MOTION *shape
Float frame

PARAMETER

 *object  Pointer to chunk object structure 
 *motion  Pointer to motion structure 
 *shape  Pointer to motion structure (apex animation) 
 frame  Frame number 

RETURN

None

DESCRIPTION

Draws a motion according to motion data.

Because floating-point notation is possible for frame numbers, interpolation of motion data is possible. For motions where the number of frames is 10, the frame number range is 0 to less than 10 (9.9999). For example, when the frame number is set to 0.5, the values for the mean between frame 0 and frame 1 are interpolated and drawn. Interpolation for frames between 9 and less than 10 (9.9999) is carried out between the last frame and the first frame.

Apex types suitable for apex animation are listed below.

 Apex  NJD_CV,NJD_CV_D8 
 Apex/normal vector  NJD_CV_VN,NJD_CV_VN_D8 

(Spline interpolation only for apex)


EXAMPLE

#define	OBJECT	object_sample	/* Entered in NJA (NAM) file */
#define	MOTION	motion_sample	/* Entered in NAM file */
#define	SHAPE	shape_sample	/* Entered in NAS file */
extern NJS_CNK_OBJECT	OBJECT[];
extern NJS_MOTION	MOTION[];
extern NJS_MOTION	SHAPE[];
float	buf[10000];
float	ff=0.f;
	:
InitShape(buf);
	:
njCnkSimpleDrawShapeMotion( OBJECT,MOTION,SHAPE,ff );
ff+=0.2f;
if( ff > (MOTION->nbFrame-1) ) ff=0.f;
	:

NOTE

This is motion for the chunk object structure. The drawing function is exactly the same as model drawing, except for the fact that motion and shape (apex animation) have been added.
