     f32 X,
     f32 Y,
     f32 Z
);

None.

This is an immediate function. It sets the light position. You must use SetLightType to set the light type to SOURCE_TYPE_POINT. This function is an immediate function. (Immediate functions directly generate commands and insert them into the command buffer.)
Note: This function sets the same registers as the Light::SetDirection function.

The format of the data inserted into the command buffer is:
0x00000000 (Y << 16) | X
0x00000004 [Reserved]
0x00000008 Z
0x0000000c [Reserved]

X, Y, and Z are each 16-bit floating point values. This function converts from a 32-bit floating point format to a 16-bit floating point format.

The default value is all 0.0f.
