Expand description

The result of a World handling an event

Variants

`ClickedFreeSpace(Pt2D)`

Tuple Fields

0: Pt2D

A left click occurred while not hovering on any object

`Dragging`

Fields

obj: ID

dx: f64

dy: f64

cursor: Pt2D

An object is being dragged. The given offsets are relative to the previous dragging event. The current position of the cursor is included.

`Keypress(&'static str, ID)`

Tuple Fields

0: &'static str

1: ID

While hovering on an object with a defined hotkey, that key was pressed.

`ClickedObject(ID)`

Tuple Fields

0: ID

A hoverable object was clicked

`Nothing`

Nothing interesting happened

Implementations

[src]

impl<I: ObjectID> WorldOutcome

[src]

pub fn map_id<O: ObjectID, F: Fn(I) -> O>(self, f: F) -> WorldOutcome<O>

If the outcome references some ID, transform it to another type. This is useful when some component owns a World that contains a few different types of objects, some of which are managed by another component that only cares about its IDs.

[src]

pub fn maybe_map_id<O: ObjectID, F: Fn(I) -> Option<O>>(
self,
f: F
) -> Option<WorldOutcome<O>>

Like map_id, but the transformation may fail.

impl<T> Downcast for T where
T: Any,

pub fn into_any(self: Box<T, Global>) -> Box<dyn Any + 'static, Global>
