Member Details

CurrentScene

Kind: Property

public Electron2D.Node CurrentScene { get; }

Summary

Gets or sets the current scene value.

Remarks

This property follows the validation and lifetime rules of its declaring type.

Value

The current current scene value.

Thread Safety

This member is not synchronized. Call it from the thread that owns the related object unless the declaring type states otherwise.

Since

This API is available since Electron2D 0.1.0 Preview.

DebugCollisionsHint

Kind: Property

public System.Boolean DebugCollisionsHint { get; set; }

Summary

Gets or sets whether collision shapes should be exposed to debug visualization.

Remarks

This property does not draw anything by itself. It enables the internal managed snapshot used by the editor viewport and automated diagnostics.

The snapshot intentionally contains scene nodes and geometry data only; it does not expose backend handles or native pointers.

Value

true to enable internal collision shape snapshots for editor and diagnostics tools; otherwise, false.

Thread Safety

This property is not synchronized. Mutate it on the main scene thread.

Since

This property is available since Electron2D 0.1.0 Preview.

Root

Kind: Property

public Electron2D.Node Root { get; }

Summary

Gets the root value.

Remarks

This property follows the validation and lifetime rules of its declaring type.

Value

The current root value.

Thread Safety

Electron2D.SceneTree()

Kind: Constructor

public Electron2D.SceneTree()

Summary

CallGroup(System.String, System.String, System.Object[])

Kind: Method

public System.Void CallGroup(System.String, System.String, System.Object[])(System.String group, System.String method, System.Object[] args)

Summary

Executes the call group operation.

Remarks

This method follows the validation and lifetime rules of its declaring type.

Parameters

• group: The group value.
• method: The method value.
• args: The args value.

ChangeSceneToPacked(Electron2D.PackedScene)

Kind: Method

public Electron2D.Error ChangeSceneToPacked(Electron2D.PackedScene)(Electron2D.PackedScene packedScene)

Summary

Executes the change scene to packed operation.

Remarks

This method follows the validation and lifetime rules of its declaring type.

Parameters

• packedScene: The packed scene value.

Returns

The result of the operation.

CreateTween()

Kind: Method

public Electron2D.Tween CreateTween()()

Summary

Creates a tween processed by this scene tree.

Remarks

The returned tween is advanced during Electron2D.SceneTree.ProcessFrame(System.Double) after node process callbacks and before draw callbacks. Add tweeners to it with Electron2D.Tween.TweenProperty(Electron2D.Object,Electron2D.NodePath,Electron2D.Variant,System.Double), Electron2D.Tween.TweenInterval(System.Double) or Electron2D.Tween.TweenCallback(Electron2D.Callable).

A tween created this way remains valid until it completes, Electron2D.Tween.Kill is called, or the tween is otherwise removed from the scene tree processing list.

Returns

A valid Electron2D.Tween instance that starts in the running state.

Thread Safety

This method is not synchronized. Call it on the main scene thread.

Since

This method is available since Electron2D 0.1.0 Preview.
