Enum HighlightKind

pub enum HighlightKind<T>
where
    T: Asset,
{
    Fixed(Handle<T>),
    Dynamic {
        function: fn(&T) -> T,
        cache: Option<Handle<T>>,
    },
}

Used to override each highlighting state in Highlight.

Variants

Fixed(Handle<T>)

A fixed override for this entity. For example, to change a material to a specific color.

Dynamic

A function that takes the base asset of the entity, and outputs a new, modified asset. This can be used to make “tinted” materials.

Fields

function: fn(&T) -> T

The function to set.

cache: Option<Handle<T>>

The function will be run when the entity’s Handle changes, and the output will be stored here.

Implementations

impl<T> HighlightKind<T>

where T: Asset,

pub fn get_handle(&self) -> Option<Handle<T>>

Get a handle to the override Asset.

pub fn get_dynamic(&mut self) -> Option<(&fn(&T) -> T, &mut Option<Handle<T>>)>

Get the dynamic override function and cache if it exists.

pub const fn new_dynamic(function: fn(&T) -> T) -> HighlightKind<T>

Create a HighlightKind::Dynamic with the supplied function. Useful when you want to tweak the initial Asset when highlighting, e.g. tinting StandardMaterial blue.
