# Objective - Bevy 0.15 added support for custom cursor images in https://github.com/bevyengine/bevy/pull/14284. - However, to do animated cursors using the initial support shipped in 0.15 means you'd have to animate the `Handle<Image>`: You can't use a `TextureAtlas` like you can with sprites and UI images. - For my use case, my cursors are spritesheets. To animate them, I'd have to break them down into multiple `Image` assets, but that seems less than ideal. ## Solution - Allow users to specify a `TextureAtlas` field when creating a custom cursor image. - To create parity with Bevy's `TextureAtlas` support on `Sprite`s and `ImageNode`s, this also allows users to specify `rect`, `flip_x` and `flip_y`. In fact, for my own use case, I need to `flip_y`. ## Testing - I added unit tests for `calculate_effective_rect` and `extract_and_transform_rgba_pixels`. - I added a brand new example for custom cursor images. It has controls to toggle fields on and off. I opted to add a new example because the existing cursor example (`window_settings`) would be far too messy for showcasing these custom cursor features (I did start down that path but decided to stop and make a brand new example). - The new example uses a [Kenny cursor icon] sprite sheet. I included the licence even though it's not required (and it's CC0). - I decided to make the example just loop through all cursor icons for its animation even though it's not a _realistic_ in-game animation sequence. - I ran the PNG through https://tinypng.com. Looks like it's about 35KB. - I'm open to adjusting the example spritesheet if required, but if it's fine as is, great.

Update your code to set them. Before: ```rust CustomCursor::Image { handle: asset_server.load("branding/icon.png"), hotspot: (128, 128), } ``` After: ```rust CustomCursor::Image { handle: asset_server.load("branding/icon.png"), texture_atlas: None, flip_x: false, flip_y: false, rect: None, hotspot: (128, 128), } ``` ## References - Feature request [originally raised in Discord].
