The Inspector is important for viewing and editing the properties of nodes or assets. You can edit the location of a node, components, pictures, materials, models and other assets of a node.
The Inspector features many details and can seem complicated. To get started, aselect the node in Scene panel, Hierarchy panel, or select the asset in Assets panel. Properties can now be displayed or edited.
The two arrows on the left are the historical records, click to switch the editing items. The lock icon on the right can lock the panel, fix the edited object, and prevent the panel from changing with the new selected item.
Editing a Node
Nodes correspond to the nodes in the tree structure in the Hierarchy panel and display the same name.
- The check box in the upper left corner indicates the activation state of the node. By default, the check box indicates that the node is in an inactive state. The node will be suspended from rendering, and the entire node, including child nodes, will be hidden when running.
- In the input box is the name of the node. The name can be empty.
- Next are several general properties of the node: position, rotation, scale, and layer.
The node menu on the right, the menu inside can be copied, paste the value of the node attribute, or you can paste a new component.
Use the Add component button, after clicking, a list of components will appear, including components provided by the system and custom script components.
The list of added components has a search box that supports the up and down arrows on the keyboard, or Enter can be used to confirm the selection.
Editing Node Components
This panel can display node components and component properties. Like the general properties of nodes, each component has a foldable or expandable header.
When multiple components are attached to a node, the scrolling range can be reduced by folding components that are not frequently modified, and improve editing efficiency.
To the right of the component name is a help document and a component menu button. The help document button can jump to the API document of the component. The component menu can be operated on: removed, moved up, moved down, copied, pasted as a value, or pasted as a new component.
The component created by the user through a script, when editing a node, can be directly dragged into the Inspector panel to generate a component.
The different properties in the script component are declared by the user in the script code. When the different types of properties are edited, the editor will automatically recognize the appropriate UI component.
The definition of properties is explained, in detail, in the Declaring Properties documentation.
How to use UI components
Properties are divided into value types and reference types.
Value type properties
Value type includes simple variable types that take up very little memory, such as numbers, strings, booleans, and enumerations:
- Number: the keyboard is used to enter digits. The up and down arrows next to the input box can gradually increase or decrease the attributes value.
- Vector (Vec2): The vector control is a combination of two numeric inputs, and the input box will identify the sub-property name corresponding to each numeric value with x and y.
- String: the keyboard is used to input strings directly in a text box. The string input control is divided into single line and multi-line. The multi-line text box can be changed by pressing Enter.
- Boolean: edited in the form of a check box. The selected state indicates that the attribute value is true, and the non-selected state indicates false.
- Enum: edited in the form of a pull-down menu. Click the enumeration menu, and then select an item from the pop-up menu list to complete the modification of the enumeration value.
Color: click the color attribute preview box, and a color picker window will pop up. In this window, you can directly click the desired color with the mouse, or directly enter the designation in the RGBA color input box below s color. Click Color Picker anywhere outside the window to close the window and use the last selected color as the attribute value. For example, the color picker component:
Reference type properties
Reference types include objects, such as nodes, components, or assets. You can select and assign values by dragging or popping up the Assets panel.
Multi-selectable nodes, inconsistent properties cannot be modified, and
-in the input component indicates that they cannot be modified.
Batch assign materials, pictures, animations and other assets, which can be dragged multiple times.
Editing Prefab Nodes
When editing a Prefab Node, the header area buttons are: disassociate, associate, locate assets, restore from assets, and update to assets.
- Disassociation refers to disconnecting the prefab node from the asset and turning it into a normal node, the color is no longer green.
Association means that a Prefab asset is selected first and then associated with the current Prefab node. The new association between common nodes and Prefab assets can be found in the top menu of the editor Edit:
Locating assets refers to locating the Prefab asset on the assets panel and making it flash.
- Restore from asset means to return an edited Prefab node, along with its child nodes, to the initial state.
- Update to asset refers to updating the Prefab node data that has been edited to the Prefab asset.
When editing assets, please pay attention to the last click to save, the green tick icon in the figure below is the save button.
