v0.3.0

Breaking changes

• 43% performance improvement from reducing allocation in the theme calculations (see Migration guide)
• On renamed to OnColor in the sickle_ui_scaffold::theme::theme_colors package to avoid collision with the upstreamed bevy_mod_picking

New features

• Allow loading theme colors from a material theme json file: #93
• Observable input events
• Documentation for ui_utils, ui_commands, and main ui_style file (NOTE: docs.rs build for the scaffold is still broken, will be fixed next release)

Fixes

• docs.rs build for the main crate and linux builds that don't specify the windowing environment for bevy
• Floating panel resize handles
• System ordering
• Flux interaction animation frame delay
• Missing default font

Migration

• All occurrence of On (sickle_ui_scaffold::theme::theme_colors) needs to be changed to OnColor
• UiContext implementations need to be updated to provide iterators instead of Vec. See: #94

Old:

impl UiContext for SizedZone {
    fn get(&self, target: &str) -> Result<Entity, String> {
        match target {
            SizedZone::RESIZE_HANDLES => Ok(self.resize_handles),
            _ => Err(format!(
                "{} doesn't exist for SizedZone. Possible contexts: {:?}",
                target,
                self.contexts()
            )),
        }
    }

    fn cleared_contexts(&self) -> Vec<&'static str> {
        vec![]
    }

    fn contexts(&self) -> Vec<&'static str> {
        vec![SizedZone::RESIZE_HANDLES]
    }
}

New:

impl UiContext for SizedZone {
    fn get(&self, target: &str) -> Result<Entity, String> {
        match target {
            SizedZone::RESIZE_HANDLES => Ok(self.resize_handles),
            _ => Err(format!(
                "{} doesn't exist for SizedZone. Possible contexts: {:?}",
                target,
                Vec::from_iter(self.contexts())
            )),
        }
    }

    fn cleared_contexts(&self) -> impl Iterator<Item = &str> + '_ {
        [].into_iter()
    }

    fn contexts(&self) -> impl Iterator<Item = &str> + '_ {
        [SizedZone::RESIZE_HANDLES].into_iter()
    }
}
