Extremely simple lighting techniques?

[Jungletoe]

Hi,

At the moment, my lighting system is extremely basic. I simply lay a VertexArray over the whole screen and slowly modify its alpha channel to simulate a day/night system. However, I need to add campfires and torches, both which require a simple circular lighting radius where there is more transparency in the filter.

At the moment, I just put a yellow alpha image over where the campfire is. The only problem is that this can end up happening if there are too many fires in one area:



Is there any way to do a simple lighting system WITHOUT shadows and WITHOUT rendertextures? I want to support as many machines as possible (not to mention that my own computer can't handle rendertextures).

This is what I'm going for:

It will be hard without a render-texture.

But render-textures should work everywhere: there's a fallback in case FBOs are not supported, and all FBOs that have been reported so far have been fixed.

Could you please report your problems with render-textures so that I can investigate?

Sure. How recently have they been fixed? I'm running SFML 2.0 from the latest build last October.

I'm running SFML 2.0 from the latest build last October.

What does "latest build" mean?
SFML 2.0 was released in april. And it's the latest version.

I meant that I downloaded "the latest build" that was available last October. I haven't downloaded it since then, so my SFML2 version is from a while ago, which is why I was wondering when you fixed these problems.

I don't remember, but you should definitely use the official release now.
