The "ChainLight" Class has a parameter in its constructor which is called "rayDirection":
ChainLight(rayHandler, rays, Color, distance, rayDirection, float[] vertices)
Apparently, if it is set to "1", the light direction is left and if it is "-1", the light direction is right.
Question: Is there a way to make it emit light in ALL directions (including up and down) without creating new instances?
The ChainLight is intended to allow you to build arbitrary shapes with light emitting out from them.
The direction of left or right ( 1 or -1 ) will be determined by which direction you define your vertices in, So you could define a chain like so:
v2(0,1)______________v3(1,1)
| |
| |
| |
v1(0,0)v5(0,0)_______v4(1,0)
Hopefully my ascii art is clear enough. We have a chain made up of 4 lines defined by 5 coordinates (1 and 5 are the same coordinates to create a closed shape). And because the vertices wind around in a clockwise direction, the direction of the light should be left - I think - to make the light shine outwards rather than inwards. Give it a try.
This hopefully gives you the left, right, up and down kind of thing you are looking for.
