I just started working with canvas in HTML5 and with javascript. I'm pretty satisfied with my game so far: http://xenopal.dk/game-v1.1/. But I'd like to implement lighting as well in the style of Terraria or Minecraft http://www.nerd-age.com/wp-content/uploads/2011/09/Terraria-New-Torches.png where you can have multiple light sources, even with color, without it being like realistic shadows that gets casted by the light.
I've tried to do per-pixel lighting, but that didn't go so well since it made my whole game lag like crazy and unplayable. I might have done the per-pixel lighting wrong since I'm fairly new to creating games in canvas.
I hope that you're able to help me or maybe pass on some links to other places that might be able to help. Thank you :)
// Edit - Probably forgot to mention that it should of course be a 2D lighting. I've read somewhere that even with three.js and pixi.js I might be able to create this kind of lighting, but I have no idea on how to do it.
