# njCnkSetSimpleMultiLightRange

Sets the effective light range of the light source for the chunk SimpleMulti light (point light source)

### FORMAT

`

  void njCnkSetSimpleMultiLightRange( light, nrange, frange )
  Int light
  Float nrange
  Float frange

`

### PARAMETER

  `light` | Light number
  `nrange` | Range that the maximum intensity of the light reaches (upper limit clamp)
  `frange` | Range reach of the position light (cut-off)

### RETURN

  None

### DESCRIPTION

  Sets the effective range of the point light source for the njCnkSimpleMultiDrawObject (njCnkSimpleMultiDrawModel).

  Enter the light number and the maximum intensity range (uniform value) and range reach (the light is cut off at this value) to be used in the parameters.

### EXAMPLE

      sbInitSystem( NJD_RESOLUTION_640x240_NTSCNI, NJD_FRAMEBUFFER_MODE_RGB565, 1 );
      njInitVertexBuffer( 1000000, 0, 1000, 0, 0 );
      njInitMatrix( matrix, 8 , 0);
      njInit3D( vbuf, 4096 );
      njInitView( &view );
      njSetView( &view );
      /* Set chunk light as 4 */
      njCnkSetSimpleMultiLight( 4 );
      /* Set direction of chunk light's parallel light source (first light source) */
      njCnkSetSimpleMultiLightVector(0.f, 0.f, -1.f);
      /* Set chunk light's point light source position */
      /* Set second light source (point light source) */
      njCnkSetSimpleMultiLightPoint(NJD_CNK_EASY_MULTILIGHT_2, 0.f, 0.f, -12.f);
      /* Set third light source (point light source) */
      njCnkSetSimpleMultiLightPoint(NJD_CNK_EASY_MULTILIGHT_3, 0.f, 0.f, -12.f);
      /* Set chunk light's point light source range (distance) */
      njCnkSetSimpleMultiLightRange(NJD_CNK_EASY_MULTILIGHT_2, 6.f, 40.f);
      njCnkSetSimpleMultiLightRange(NJD_CNK_EASY_MULTILIGHT_3, 6.f, 40.f);
      njCnkSetSimpleMultiLightRange(NJD_CNK_EASY_MULTILIGHT_4, 6.f, 40.f);
      /* Set chunk light's ambient color */
      njCnkSetSimpleMultiAmbient(0.1f, 0.1f, 0.1f);
      /* Set the chunk light's light source color */
      njCnkSetSimpleMultiLightColor(NJD_CNK_EASY_MULTILIGHT_1, 0.6f, 0.5f, 0.3f);
      njCnkSetSimpleMultiLightColor(NJD_CNK_EASY_MULTILIGHT_2, 1.f, 0.5f, 0.5f);
      njCnkSetSimpleMultiLightColor(NJD_CNK_EASY_MULTILIGHT_3, 0.5f, 1.f, 0.5f);
      njCnkSetSimpleMultiLightColor(NJD_CNK_EASY_MULTILIGHT_4, 0.5f, 0.5f, 1.f);
      	:
      njClearMatrix();
      /* Set chunk light direction-position reflection */
      njCnkSetSimpleMultiLightMatrices();
      njTranslate( NULL, 0.f, 0.f, -10.f );
      njRotateXYZ( NULL, rx,ry,rz );
      njCnkSimpleMultiDrawObject;
