Gizmos 2D Utilities

The Gizmos2D class provides helper methods for drawing 2D shapes in the Unity Editor using Gizmos. These utilities simplify visual debugging by allowing you to easily draw shapes such as circles, squares, and cones on the XY plane.

DrawWireCircle(Vector3 position, float radius)

Draws a wireframe circle at the given position.

• position: Center of the circle.
• radius: Radius of the circle.

Gizmos2D.DrawWireCircle(transform.position, 2f);

This uses Gizmos.DrawWireSphere, restricted to the XY plane.

DrawCircle(Vector3 position, float radius)

Draws a circle using line segments.

• position: Center of the circle.
• radius: Radius of the circle.

Gizmos2D.DrawCircle(Vector3.zero, 1.5f);

Constructed with 64 vertices for smoothness.

DrawSquare(Vector3 position, Vector2 size)

Draws a square centered at the specified position.

• position: Center of the square.
• size: Width and height of the square.

Gizmos2D.DrawSquare(transform.position, new Vector2(2f, 2f));

The corners are automatically calculated and connected in order.

DrawCone(Vector3 position, float radius, float angle)

Draws a cone originating from the specified position.

• position: Cone's origin.
• radius: Length of the cone's reach.
• angle: Cone's angle in degrees (clamped to 360).

Gizmos2D.DrawCone(Vector3.zero, 5f, 90f);

This method draws the cone using line segments and includes outer edge lines to visualize the angle spread.
