The hierarchy panel is located on the far left side of the editor. It displays all the nodes in the current scene in a tree structure. The scene node is the parent node of all other nodes, including cameras, lights, meshes, etc.

In the hierarchy panel, you can:

• Add, delete, or clone a node
• Copy the path information of a node
• Adjust the hierarchy of nodes by dragging
• Fuzzy search for nodes in the scene
• Temporarily hide a node

Adding, Deleting, and Copying Nodes

Adding Nodes

You can add empty nodes or quickly add nodes with corresponding functional components, such as nodes with camera components, light source components, and basic 3D/2D rendering components.

You can click the "+" button in the hierarchy tree panel to add a node. Note that if you have a node selected, the added node will become a child node of the selected node; otherwise, it will default to being a child node of the scene:

After adding, you can edit the properties of the new node in the Inspector Panel.

Deleting Nodes

To delete a node, you can use the following methods:

• Select the node to be deleted -> Click the delete button
• Select the node to be deleted -> Press the Delete key
• Right-click a node -> Delete

Copying Nodes

Copying a node will copy the selected node and all its child nodes, essentially calling the engine's clone capability.

After selecting a node, you can quickly clone the node at the same level by using Duplicated.

You can also choose copy and paste separately to achieve cross-level copying.

Additionally, you can quickly copy the selected node using the shortcut key ⌘ + D.

Node Sorting

To better organize nodes, you can sort nodes by dragging. After selecting a node, you can change its position in the hierarchy tree by dragging it with the left mouse button.

Node Search

There is a search box at the top of the hierarchy panel where users can enter the name of a node to search for nodes in the scene. The search box supports fuzzy search, allowing you to enter part of the node's name to find it.

Node Hiding

Each entity node has an eye button on the right side. Clicking it toggles the node's visibility in the scene.

Note that adjusting the node's visibility here only affects the workspace and not the isActive property in the Inspector Panel.

Shortcuts

The following operations are effective only after selecting a node.
