# Objective This adds support for using texture atlas sprites in UI. From discussions today in the ui-dev discord it seems this is a much wanted feature. This was previously attempted in #5070 by @ManevilleF however that was blocked #5103. This work can be easily modified to support #5103 changes after that merges. ## Solution I created a new UI bundle that reuses the existing texture atlas infrastructure. I create a new atlas image component to prevent it from being drawn by the existing non-UI systems and to remove unused parameters. In extract I added new system to calculate the required values for the texture atlas image, this extracts into the same resource as the existing UI Image and Text components. This should have minimal performance impact because if texture atlas is not present then the exact same code path is followed. Also there should be no unintended behavior changes because without the new components the existing systems write the extract same resulting data. I also added an example showing the sprite working and a system to advance the animation on space bar presses. Naming is hard and I would accept any feedback on the bundle name! --- ## Changelog > Added TextureAtlasImageBundle --------- Co-authored-by: ickshonpe <david.curthoys@googlemail.com> |
