I’m optimizing the videogame I’m currently working on. It has several animations, and wanted to optimize it as much as possible. Right now, the sprite sheets are a 1024x1024 png, but would like to use a 512x512 jpg, but then I wouldn’t have the alpha channel, so I wondered if Corona provides a color key property. I’ve been looking for it and found the display.setDefault(), it’s not what I was looking for…
Any idea?
Maybe this is a basic question, but what’s a color key?
color keying is used to remove the background color and set an alpha channel to a jpg. In lots of 2D games, the sprite sheets used in animations have a background color [usually a pink one, (255, 0, 255)] to avoid using png’s
There is no color key property in Corona. Sorry.
What a shame… Well, thanks anyway 
I should add that it may be supported in our upcoming Graphics 2.0 update.
Wow, that would be nice! Do you know when will it be released, more or less?
