##### 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.
