This is a VX resource script that automatically creates an eye candy effect for “Tile C” RTP window tiles. It lets light stream in from the outside, like the screenshot shown above. Many people use “picture” type events for the same type of effect.

The instructions for this one are more complex than most scripts, but it’s also plug & play. If you can’t figure out what to change from looking below & at the script itself - don’t edit it!

AutoLightTiles[id] = [x-off,y-off,width,height]
AutoLightStart[id] = starting opacity
AutoLightColors[id] = color hash, alpha’s above
AutoLightOpac = opacity of ALL lights. can use as variable instead with “$game_variables[#]“. it’s an evaluated string
AutoLightZ = z layer for ALL lights
