Struct Mouse 

Source 
pub struct Mouse {
    pub position: Vector2<f32>,
    pub speed: Vector2<f32>,
    pub buttons_state: FxHashMap<ButtonId, ElementState>,
    pub pressed_buttons: FxHashSet<ButtonId>,
    pub released_buttons: FxHashSet<ButtonId>,
}
Expand description

Represents the mouse state in the current frame. The contents of this structure is a simplified version of event-based approach. Important: this structure does not track from which mouse the corresponding event has come from, if you have more than one mouse use event-based approach instead!

Fields§

§position: Vector2<f32>

Coordinates in pixels relative to the top-left corner of the window.

§speed: Vector2<f32>

Speed of the mouse in some units.

§buttons_state: FxHashMap<ButtonId, ElementState>

Physical state of mouse buttons. Usually, the button indices are the following:

  • 0 - left mouse button
  • 1 - right mouse button
  • 2 - middle mouse button
  • 3 - additional mouse button (could back or forward)
  • 4 - additional mouse button (could back or forward)
  • 5 and higher - device-specific buttons

There are named constants for the tree most used ones - Mouse::LEFT_BUTTON, Mouse::RIGHT_BUTTON, Mouse::MIDDLE_BUTTON.

§pressed_buttons: FxHashSet<ButtonId>

A hash set that contains all the buttons that were pressed in the current frame. If a button is still pressed in the next frame, this hash map will not contain it. This is useful to check if a button was pressed and some action, but do not repeat the same action over and over until the button is released.

§released_buttons: FxHashSet<ButtonId>

A hash set that contains all the buttons that were released in the current frame. If a button is still released in the next frame, this hash map will not contain it. This is useful to check if a button was released and some action, but do not repeat the same action over and over until the button is pressed.
