Description

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

Performance: Primitive shapes, especiallySphereShape3D, are fast to check collisions against.ConvexPolygonShape3D andHeightMapShape3D are slower, andConcavePolygonShape3D is the slowest.

floatcustom_solver_bias =0.0🔗

• voidset_custom_solver_bias(value:float)

• floatget_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 to0, the default value fromProjectSettings.physics/3d/solver/default_contact_bias is used.

floatmargin =0.04🔗

• voidset_margin(value:float)

• floatget_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.
