Sim/graphics/animation/lights/wigwag
From X-Plane SDK
INPUTS:
Red and green are used for normal vector rescaling - see PluginsAndObjects for more info. Blue level controls the flash speed. Alpha provides a time offset to flashing.
OUTPUTS:
RGB color is set to white. Alpha is set to brightness or 0 for off.
SPECIAL BEHAVIOR:
This light turns off when runway lights are inoperative.
The object sequence number can change the phase of this light.
DESCRIPTION:
The wigwag light modulates its brightness based on the angle the user looks at it -- it will go dim if viewed too far off angle above, below, left or right. The RG components rescale the normal. The "direction" of this light is always along the Z axis (subject to animation).
The wigwag light also pulses on and off - the color controls the timing.
