Ninja Library - Motion Function

njFastDrawShapeMotion

Draws motion with shapes

FORMAT

void njFastDrawMotion( *object, *motion, *shape, frame )
NJS_OBJECT *object
NJS_MOTION *motion
NJS_MOTION *shape
Float frame

PARAMETER

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

RETURN

None

DESCRIPTION

Draws motion according to the 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. The same applies for apex animation.

EXAMPLE

#include <Shinobi.h>
#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_OBJECT	OBJECT[];
extern NJS_MOTION	MOTION[];
extern NJS_MOTION	SHAPE[];
float	buf[10000];
float	ff=0.f;
	:
InitShape(buf);
	:
njFastDrawShapeMotion( OBJECT,MOTION,SHAPE,ff );
ff+=0.2f;
if( ff >= (MOTION->nbFrame-1) ) ff=0.f;
	:

NOTE

This drawing function is exactly the same as model drawing, except for the fact that motion and shape (apex animation) have been added. In other words, all of the njControl3D() settings are identical. Because the model functions correspond to njFastDrawObject() function, the light source is a bright light.
