So what I want to do is add some lights/fake lights.
Simple put once a light is placed in an area it illuminates so far out. I do this by jus drawing a filter that shades over the whole area making the illusion of light where I am actully just making parts darker. My problem is adding more than 1 light. Since GM only lets you darken and not lighten areas I have to draw 8 other squares that are full dark around the one that has the ellipse imitating the light. Adding more than one light when these can collide with each other or even moving light say with a flash light become more difficult.
Can anyone give me an example of a way to make this work? Thank you.
