Struct bevy_retrograde_epaint::emath::Pos2 [−]
Expand description
A position on screen.
Normally given in points (logical pixels).
Mathematically this is known as a “point”, but the term position was chosen so not to conflict with the unit (one point = X physical pixels).
Fields
x: f32
y: f32
Implementations
impl Pos2
impl Pos2
The zero position, the origin.
The top left corner in a GUI.
Same as Pos2::default()
.
Use Pos2::ZERO instead
The vector from origin to this position.
p.to_vec2()
is equivalent to p - Pos2::default()
.
pub fn distance_sq(self, other: Pos2) -> f32
