I may be blind, however I find myself unable to pick color and opacity values at the given location. Therefore I am requesting the following:
An expression or object that allows reading the color and opacity values of a given object at specific coordinates.
GetRGB(TiledBackground,200x100) would return the color of pixel at 200x100 within the TiledBackground texture.
GetOpacity, etc. would be helpful as well.
The uses are many! In my specific case, height mapping. Make characters appear bigger on darker (higher) places and smaller on lighter (lower) places. But that is not the only use. There is Line of Sight etc.
If this is an unrealistic feature request, however, my world won't be crushed. There is always another way.
