Returns: N/A
To use lighting you obviously need to define lights. In
GameMaker: Studio two different lights exist: directional
lights (like the sun), and positional lights. This function is for
a positional light, where you can define the x, y and z position of
the light, the light range and the colour of the light (which will
also affect the perceived intensity of the light as certain colours
appear "darker" than others). You must also give the light an index
number which what will be used in other functions to reference
it.
Note: There are only 8 hardware lights available, so you
should use these functions to define and manage "active" lights,
not all lights in the scene.
d3d_set_lighting(true);
d3d_light_define_point(1, 200, 123, 50, 2000, c_white);
d3d_light_enable(1, true);
The above code will enable lighting for the whole scene, then define a white light at a specific point in the room space, and finally turn that light on.
