Ninja Library - Motion Function

njCameraAction

Executes camera motion

FORMAT

void njCameraAction( *caction, frame )
NJS_CACTION *caction
Float frame

PARAMETER

 *caction  Pointer to camera action structure 
 frame  Frame number 

RETURN

None

DESCRIPTION

Draws the camera 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.


EXAMPLE

#include <Shinobi.h>
#define	OBJECT	object_sample
#define	CACTION	caction_sample
extern NJS_CACTION	CACTION[];
	:
njCameraAction( CACTION,ff );
ff+=0.2f;
if( ff >= (CACTION->motion->nbFrame-1) ) ff=0.f;
	:

NOTE

This function is designed for use in NAC and NAM files.
