I’d like to be able to change the alpha channel for a sprite so that the whole sprite can appear transparent when certain things happen, I’d prefer not to create a bunch of new PNGs with the alpha baked in as I’d like to be able to animate the level and don’t want to incur the cost of having dozens of images. I’ve hunted around and can’t find an obvious way of controlling this, what’s the simplest way of achieving this?
Thanks in advance.
