design and characters September 23 2012


I am designing sprites for characters at the moment and really like the semi-transparency look when I use the photoshop brushes in my sprite/pixel art.

However, I AM worried about performance related to all of those semi transparency "pixels" in C2.

The game is being made to be played on PC (not phones) should I limit/not use/be concerned about using this kind of feathering effect? Will it dramatically effect performance?

Should I be using PNG 24 to get that softened look?Awakening2012-09-23 08:01:44

Unless I'm somehow horribly mistaken, I don't think you'll notice any effect on performance using this on a PC. It's possible there could be a SLIGHT effect on really really bad computers or on mobile, but I really can't see this being a problem!

It will have zero effect on performance. GPUs are so fast they can effectively draw images the same speed regardless of size, rotation and content. You should worry about other things!

I use PNG24 transparency to make Black to Transparent gradients and use them all the time.

What other things should I worry about? Is there an article on PC performance issues?
