A fast, easy to use, free, and community supported 2D game engine
Hi,
My Game features a night mode in which I add a black overlay on top of the artwork to make it appear dark. now I need to add a torch/candle sort of thing which user can use to navigate around. The idea is a certain area around the torch (say in 50 pixels radius) would be illuminated so that user can actually see what's in there. I know I can do it through texture blending but don't know how exactly should I start with implementation. ny ideas will be appreciated.

Also search for the Touch Copter game, there was some discussion in the announcement thread for that game.
Hi Steve,
I have gone through the links you suggested, can you please be a little more elaborate (I am sorry if this is dumb, I haven't had any coffee in 36 hours ;-) ).
here's what I'm doing:
- I am using the RenderTexture class from jason (yeah, being lazy), and BlendSprite. I have followed the approach he suggested on google groups. I am using a background as the burn-layer and quickly made gradient as brush/light/torch. However, when I draw it over the burn-able layer, it doesn't make any changes to it. (I know it's something very basic).

It sounds like you are getting the draw order wrong. You use the blend sprite to punch holes in the burn-able layer by setting the masking so only alpha is applied. You draw the burn-able layer over the top of the background and where you have punched holes in the render texture the background should show through.
If you post your code it is much easier to explain.
