Class Shape3D

Abstract base class for 3D shapes used for physics collision.

Inheritance
Shape3D
Derived

Remarks

Abstract base class for all 3D shapes, intended for use in physics.

Performance: Primitive shapes, especially SphereShape3D, are fast to check collisions against. ConvexPolygonShape3D and HeightMapShape3D are slower, and ConcavePolygonShape3D is the slowest.

Properties

custom_solver_bias

The shape's custom solver bias. Defines how much bodies react to enforce contact separation when this shape is involved.

When set to 0, the default value from physics/3d/solver/default_contact_bias is used.

var custom_solver_bias : float = 0.0

Property Value

float

Remarks

  • void set_custom_solver_bias(float value)
  • float get_custom_solver_bias

margin

The collision margin for the shape. This is not used in Godot Physics.

Collision margins allow collision detection to be more efficient by adding an extra shell around shapes. Collision algorithms are more expensive when objects overlap by more than their margin, so a higher value for margins is better for performance, at the cost of accuracy around edges as it makes them less sharp.

var margin : float = 0.04

Property Value

float

Remarks

Methods

get_debug_mesh

Returns the ArrayMesh used to draw the debug collision for this Shape3D.
