Expand description
A SystemParam
for drawing gizmos.
They are drawn in immediate mode, which means they will be rendered only for
the frames in which they are spawned.
Gizmos should be spawned before the Last
schedule to ensure they are drawn.
Fields§
§config: &'w GizmoConfig
The currently used GizmoConfig
config_ext: &'w T
The currently used GizmoConfigGroup

pub fn arc_2d( &mut self, position: Vec2, direction_angle: f32, arc_angle: f32, radius: f32, color: Color ) -> Arc2dBuilder<'_, 'w, 's, T>
Draw an arc, which is a part of the circumference of a circle, in 2D.
This should be called for each frame the arc needs to be rendered.
§Arguments
position
sets the center of this circle.radius
controls the distance fromposition
to this arc, and thus its curvature.direction_angle
sets the clockwise angle in radians betweenVec2::Y
and the vector fromposition
to the midpoint of the arc.arc_angle
sets the length of this arc, in radians.
§Example
fn system(mut gizmos: Gizmos) {
gizmos.arc_2d(Vec2::ZERO, 0., PI / 4., 1., Color::GREEN);
// Arcs have 32 line-segments by default.
// You may want to increase this for larger arcs.
gizmos
.arc_2d(Vec2::ZERO, 0., PI / 4., 5., Color::RED)
.segments(64);

pub fn arc_3d( &mut self, angle: f32, radius: f32, position: Vec3, rotation: Quat, color: Color ) -> Arc3dBuilder<'_, 'w, 's, T>
Draw an arc, which is a part of the circumference of a circle, in 3D. For default values this is drawing a standard arc. A standard arc is defined as
- an arc with a center at
Vec3::ZERO
- starting at
Vec3::X
- embedded in the XZ plane
- rotates counterclockwise
This should be called for each frame the arc needs to be rendered.
§Arguments
angle
: sets how much of a circle circumference is passed, e.g. PI is half a circle. This value should be in the range (-2 * PI..=2 * PI)radius
: distance between the arc and it’s center pointposition
: position of the arcs center pointrotation
: defines orientation of the arc, by default we assume the arc is contained in a plane parallel to the XZ plane and the default starting point is (position + Vec3::X
)color
: color of the arc
§Builder methods
The number of segments of the arc (i.e. the level of detail) can be adjusted with the
.segments(...)
method.
§Example
fn system(mut gizmos: Gizmos) {
// rotation rotates normal to point in the direction of `Vec3::NEG_ONE`
let rotation = Quat::from_rotation_arc(Vec3::Y, Vec3::NEG_ONE.normalize());

pub fn short_arc_3d_between( &mut self, center: Vec3, from: Vec3, to: Vec3, color: Color ) -> Arc3dBuilder<'_, 'w, 's, T>
Draws the shortest arc between two points (from

point.
§Arguments
center
: The center point around which the arc is drawn.from
: The starting point of the arc.to
: The ending point of the arc.color
: color of the arc

is not equal to the radius, then the results will behave as if this were the case
