Struct bevy::ui::RelativeCursorPosition

pub struct RelativeCursorPosition {
    pub normalized_visible_node_rect: Rect,
    pub normalized: Option<Vec2>,
}

A component storing the position of the mouse relative to the node, (0., 0.) being the top-left corner and (1., 1.) being the bottom-right If the mouse is not over the node, the value will go beyond the range of (0., 0.) to (1., 1.)

It can be used alongside Interaction to get the position of the press.

The component is updated when it is in the same entity with Node.

Fields

normalized_visible_node_rect: Rect

Visible area of the Node relative to the size of the entire Node.

normalized: Option<Vec2>

Cursor position relative to the size and position of the Node. A None value indicates that the cursor position is unknown.

Implementations
