Module custom/shared_actions

Shared Actions is a system in Blockbench to allow actions (including in toolbars, menus, via action control, or keybinding) to run different code in different cases, such as in different modes or different panels. As an example, the "Duplicate" action runs code to duplicate elements when used in the outliner, and duplicates textures when used in the textures panel.

Handlers can be added for existing actions like this:

Example:

// Duplicate layers when using "Duplicate" in the layers panel
SharedActions.add('duplicate', {
	subject: 'layer',
	condition: () => Prop.active_panel == 'layers' && TextureLayer.selected,
	run() {
		let texture = Texture.selected;
		let original = texture.getActiveLayer();
		let copy = original.getUndoCopy(true);
		copy.name += '-copy';
		Undo.initEdit({textures: [texture]});
		let layer = new TextureLayer(copy, texture);
		layer.addForEditing();
		Undo.finishEdit('Duplicate layer');
	}
})
