CollisionShape3D — C# API

class CollisionShape3DReckfellSharpInherits Entity3D

CollisionShape3D must be a direct child of a suitable CollisionObject. Shape is shared: resizing a common resource affects every instance using it. Assign a Duplicate before editing independent geometry.

Change resource dimensions with unit scale in the physics branch, including inherited scale checks. Disabled removes the shape from physics participation after application. Use SetDeferred inside a physics signal rather than immediate restructuring. Hiding the visible model does not disable collision.

CollisionShape3DConstructor

# CollisionShape3D

C#
public CollisionShape3D();

Properties4

DebugColorProperty

# DebugColor

C#
public Color DebugColor { get; set; }

The collision shape color that is displayed in the editor, or in the running project if Debug > Visible Collision Shapes is checked at the top of the editor. Note: The default value is ProjectSettings.debug/shapes/collision/shape_color. The Color(0, 0, 0, 0) value documented here is a placeholder, and not the actual default debug color.

DebugFillProperty

# DebugFill

C#
public bool DebugFill { get; set; }

If true, when the shape is displayed, it will show a solid fill color in addition to its wireframe.

DisabledProperty

# Disabled

C#
public bool Disabled { get; set; }

Excludes the shape from physics participation after application. Use SetDeferred from a physics callback; hiding artwork does not substitute for this flag.

ShapeProperty

# Shape

C#
public Shape3D Shape { get; set; }

A geometry resource that can be shared across instances. Resizing affects all users; assign a Duplicate first for an independent collider.
