Overview

A node that provides a thickened polygon shape (a prism) to a CollisionObject3D parent and allows to edit it. The polygon can be concave or convex. This can give a detection shape to an Area3D or turn PhysicsBody3D into a solid object.

Warning: A non-uniformly scaled CollisionShape3D will likely not behave as expected. Make sure to keep its scale the same on all axes and adjust its shape resource instead.

Types

type Advanced

type Advanced = class

Advanced exposes a 1:1 low-level instance of the class, undocumented, for those who know what they are doing.

type Any

type Any interface {
	gd.IsClass
	AsCollisionPolygon3D() Instance
}

type Extension

type Extension[T gdclass.Interface] struct{ gdclass.Extension[T, Instance] }

Extension can be embedded in a new struct to create an extension of this class. T should be the type that is embedding this Extension

func (*Extension[T]) AsCollisionPolygon3D

func (self *Extension[T]) AsCollisionPolygon3D() Instance

func (*Extension[T]) AsNode

func (self *Extension[T]) AsNode() Node.Instance

func (*Extension[T]) AsNode3D

func (self *Extension[T]) AsNode3D() Node3D.Instance

func (*Extension[T]) AsObject

func (self *Extension[T]) AsObject() [1]gd.Object

type ID

type ID Object.ID

ID is a typed object ID (reference) to an instance of this class, use it to store references to objects with unknown lifetimes, as an ID will not panic on use if the underlying object has been destroyed.

func (ID) Instance

func (id ID) Instance() (Instance, bool)

type Instance

type Instance [1]gdclass.CollisionPolygon3D

Instance of the class with convieniently typed arguments and results.

var Nil Instance

Nil is a nil/null instance of the class. Equivalent to the zero value.

func New

func New() Instance

func (Instance) AsCollisionPolygon3D

func (self Instance) AsCollisionPolygon3D() Instance

func (Instance) AsNode

func (self Instance) AsNode() Node.Instance

func (Instance) AsNode3D

func (self Instance) AsNode3D() Node3D.Instance

func (Instance) AsObject

func (self Instance) AsObject() [1]gd.Object

func (Instance) DebugColor

func (self Instance) DebugColor() Color.RGBA

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.

func (Instance) DebugFill

func (self Instance) DebugFill() bool

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

func (Instance) Depth

func (self Instance) Depth() Float.X

Length that the resulting collision extends in either direction perpendicular to its 2D polygon.

func (Instance) Disabled

func (self Instance) Disabled() bool

If true, no collision will be produced. This property should be changed with Object.SetDeferred.

func (Instance) ID

func (self Instance) ID() ID

func (Instance) Margin

func (self Instance) Margin() Float.X

The collision margin for the generated Shape3D. See Shape3D.Margin for more details.

func (Instance) Polygon

func (self Instance) Polygon() []Vector2.XY

Array of vertices which define the 2D polygon in the local XY plane.

func (Instance) SetDebugColor

func (self Instance) SetDebugColor(value Color.RGBA)

SetDebugColor sets the property returned by [GetDebugColor].

func (Instance) SetDebugFill

func (self Instance) SetDebugFill(value bool)

SetDebugFill sets the property returned by [GetEnableDebugFill].

func (Instance) SetDepth

func (self Instance) SetDepth(value Float.X)

SetDepth sets the property returned by [GetDepth].

func (Instance) SetDisabled

func (self Instance) SetDisabled(value bool)

SetDisabled sets the property returned by [IsDisabled].

func (Instance) SetMargin

func (self Instance) SetMargin(value Float.X)

SetMargin sets the property returned by [GetMargin].

func (*Instance) SetObject

func (self *Instance) SetObject(obj [1]gd.Object) bool

func (Instance) SetPolygon

func (self Instance) SetPolygon(value []Vector2.XY)

SetPolygon sets the property returned by [GetPolygon].

func (Instance) Virtual

func (self Instance) Virtual(name string) reflect.Value
