Class CellGridPreviewWidget

Reusable editor widget for rendering a live cell grid preview in the inspector. Uses a hybrid approach: Texture2D for background colors, IMGUI labels for characters. Caches textures per owner instance ID to avoid recreating them every frame.

Syntax

[InitializeOnLoad]
public static class CellGridPreviewWidget

Remarks

Character rendering uses one rich-text GUI.Label per row for efficiency. Because character spacing is controlled by the font's glyph metrics rather than pixel-perfect cell boundaries, slight horizontal drift may occur in wide grids. This is an accepted limitation that keeps draw call count manageable.

Methods

ClearCache(EntityId)

Clears the cached preview texture for the specified owner. Call when the editor is disabled or destroyed.

Declaration

public static void ClearCache(EntityId ownerID)

Parameters

Type	Name	Description
EntityId	ownerID	Instance ID of the owning editor.

CreateForInspector(Func<ITextModeGridProvider>, Func<bool>, EntityId)

Creates an IMGUIContainer that renders the live cell grid preview using the existing IMGUI drawing code. Suitable for embedding in UI Toolkit inspectors.

Declaration

public static IMGUIContainer CreateForInspector(Func<ITextModeGridProvider> providerGetter, Func<bool> isInitializedGetter, EntityId ownerID)

Parameters

Type	Name	Description
Func<ITextModeGridProvider>	providerGetter	Delegate that returns the current grid provider.
Func<bool>	isInitializedGetter	Delegate that returns whether the view is initialized.
EntityId	ownerID	Instance ID of the owning editor, used to cache the preview texture.

Returns

Type	Description
IMGUIContainer

Draw(ITextModeGridProvider, EntityId)

Draws a live cell grid preview for the specified grid provider.

Declaration

public static void Draw(ITextModeGridProvider provider, EntityId ownerID)

Parameters

Type	Name	Description
ITextModeGridProvider	provider	The grid provider to preview.
EntityId	ownerID	Instance ID of the owning editor, used to cache the preview texture.
