njSetCurrentMotion | Japanese
    겂|INDEX|겈
Set parameters of the node motion function.

### Syntax

      #include <Ninja.h>
      void  njSetCurrentMotion(NJS_MOTION *motion, Float frame );
      NJS_MOTION  *motion
      Float       frame

### Arguments

motion
  Pointer to motion structure
frame
  Frame number

### Return Value

  None

### Error

  None

### Description

  Set motion parameters at each node.

### Usage Example

      #include <NINJA.H>

      #define  OBJECT    object_sample
      #define  MOTION    motion_sample
      #define LINEAR    0
      #define SPLINE    1

      extern NJS_MOTION  MOTION[];
      extern NJS_OBJECT  OBJECT[];

      Float  ff = 0.f;
      Int  spline_flg = SPLINE;

      ...........

      Sint32 njUserMain(void)
      {
        ...........

        njSetCurrentMotion(MOTION, ff );
        PushPopMotion( OBJECT );

        ff+=0.2f;
        if( ff >= (MOTION->nbFrame-1) ) ff=0.f;
        ...........
      }

      PushPopMotion(NJS_OBJECT *obj)
      {
        njPushMatrix( NULL );

        /* Execute motion function */
        njMotionTranslate( NULL, obj, spline_flg );
        njMotionRotateXYZ( NULL, obj, spline_flg );
        njMotionScale( NULL, obj, spline_flg );
        njSetNextMotionNode();

        /* Draw picture of model */
        if( obj->model != NULL )
          njDrawModel( obj->model );

        if( obj->child != NULL )
          PushPopMotion( (NJS_OBJECT*)obj->child );

        njPopMatrix( 1 );

        if( obj->sibling != NULL )
          PushPopMotion( (NJS_OBJECT*)obj->sibling );
      }

      ...........

### Remark

  This function is used as one of the functions for navigating the parent-child hierarchy (push/pop).
  These functions (motion of each node) are similar, with exception of the 3D control,
  to the njAction and njDrawMotion groups.
