<description>
|
|
Abstract base class for all 3D shapes, intended for use in physics.
|
|
[b]Performance:[/b] Primitive shapes, especially [SphereShape3D], are fast to check collisions against. [ConvexPolygonShape3D] and [HeightMapShape3D] are slower, and [ConcavePolygonShape3D] is the slowest.

<member name="custom_solver_bias" type="float" setter="set_custom_solver_bias" getter="get_custom_solver_bias" default="0.0">
|
|
The shape's custom solver bias. Defines how much bodies react to enforce contact separation when this shape is involved.
|
|
When set to [code]0[/code], the default value from [member ProjectSettings.physics/3d/solver/default_contact_bias] is used.

<member name="margin" type="float" setter="set_margin" getter="get_margin" default="0.04">
|
|
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.
