Continued Development of Jack be Jumping

Say hello to Jill, a new playable character in Jack Be Jumping! Her addition to the play store version of the game was included in the 2021 Halloween update for the game. Unfortunately Jack Be Jumping’s Christmas update was delayed, but sometime soon players will be able to jump their way through the rather unsafe Workshop area.

I’ll make sure to update every platform this time instead of just the one on Google Play.

Some things I’ve picked up:

• If you’re using modulated grayscale textures, you can import the texture as Luma + Alpha and save VRAM, but to do so the pixel format of the PNG file must be in GrayA and the texture must be imported uncompressed – which results in a much larger file so it’s best to use for a singular Atlas.
• UV mapping a texture Atlas to a polygon is much more performant than a sprite with a region when there is a lot of fully transparent space around sprite content on mobile.
