nn::gd::CTR::Light::SetDirection Member Function

void SetDirection(
     f32 X,
     f32 Y,
     f32 Z
);

	Name	Description
in	X	Sets the x-coordinate of the light source.
in	Y	Sets the y-coordinate of the light source.
in	Z	Sets the z-coordinate of the light source.

None.

This is an immediate function. Sets the light direction. SOURCE_TYPE_DIRECTIONAL must be specified for the light type to be set using SetLightType. (The resulting command from the immediate function is inserted into the command buffer.)
Note: This function sets the same registers as the Light::SetDirection function.

The format of commands that can be put in the command buffer:
0x00000000 (Y << 16) | X
0x00000004 [Reserved]
0x00000008 Z
0x0000000c [Reserved]
X, Y, and Z each have 16-bit floating point values. This function converts from a 32-bit floating point format to a 16-bit floating point format.
