Hi,
For my game I need a few lights. Not a full light system with wall detection, etc.. No, just some points that "glow".
I found two solutions to do it, but I don't know wich is the best :
1) I just use a sf::CircleShape with a texture of a circular gradient from white to black (transparent), I can use setColor to color it and I draw it each frame with an additive blend mode => simple
2) I use a class to store a vextex array of triangles, my color, my position etc... I calculate the color of each verticle before to add them in the array. I can draw the vextex array with additive blend mode (inspired from Gregouar light system). I haven't tested this solution yet
As it is for a very simple light system, I'm tempted by the first solution, however I wonder if there are any advice or warnings about each solution (like the rendering speed, ...) ?
I haven't spoken about shaders because I can't figure how the hell they work :p
