Basic Operations

Displaying Fusion Editor

In the initial Scene Composer layout, Fusion appears next to the Scene Editor in the center of the window. If Fusion is not visible, go to View > Fusion > Fusion from the menu bar and check Fusion to display it.

Diagram Display Operations

See Fusion Editor UI for basic operations related to the diagrams displayed within Fusion panel.

Diagram Bird's Eye feature

The Diagram Bird's Eye panel can be displayed by selecting [ View > Fusion > Diagram Bird's Eye ] from the menu bar. This panel provides a bird's eye view of the entire Fusion diagram. For details on how to display the panel and basic operations, please refer to Diagram Bird's Eye.

Adding a Fusion node

New fusion nodes can be added to any fusion node by the following operations. The added Fusion nodes are connected via links from connectors.

Use a connector
1. Drag a connector of any Fusion node and move a mouse.
2. A link will appear following a mouse operation, and release a mouse button anywhere.
3. "Select Fusion Node" dialog box will appear, so select Fusion node you need to add.

Entering the behavior name you want to connect to in the search box at the top of [ Choose Behavior ] dialog box narrows down the items displayed in the dialog box.

Fusion Node collapsing and expanding

Each Fusion Node has an expand/collapse button at the upper right corner. Clicking it will toggle between collapsing and expanding the Fusion node.

Reference Fusion Node

You can create a reference to behaviors available in the solution. For more information about this operation, see Behaviors: Deep Copy/Paste Operation. A reference icon appears in the upper left corner of the Fusion node corresponding to that reference behavior. This is the same icon that appears for the behavior in the Extra Scenes tree. Click this icon to navigate to the referenced Fusion node.

Fusion Group (Behavior Group)

Fusion Group (behavior group) is a way to group multiple Fusion nodes in a scene tree or Fusion diagram to make them easier to manage or to simplify diagram organization. Once created, the groups can be renamed to anything desired or duplicated for other uses. It is easier and faster to use because it does not require the creation of templates like a Behavior Building Block.

To create a Fusion group, select the target Fusion nodes and then select [ Create Group ] from the context menu.

Double-clicking on the created Fusion group will display a diagram of the grouped Fusion nodes (Figure 1 below).
Click the arrow in the upper right corner of the Fusion Group diagram or double-click the top node in the group to return to the diagram one level up (Figure 2).

Moving Fusion nodes

Drag a Fusion node to move it to any location in Fusion panel. If multiple fusion nodes are selected by either of the following operations, all Fusion nodes will be moved.

Ctrl-click to select multiple fusion nodes.
Select multiple Fusion nodes with a rectangular selection after dragging with a mouse left button.

Copy and Paste a Fusion node

A Selected Node can be copied by pressing Ctrl + C. A copied Node can be pasted by pressing Ctrl + V. If multiple fusion nodes are selected by either of the following operations, all Fusion nodes will be copied.

Ctrl-click to select multiple fusion nodes.
Select multiple Fusion nodes with a rectangular selection after dragging with a mouse left button.

Delete a Fusion node

The delete operation can be executed by selecting the target Fusion node and pressing the Delete button on the keyboard or by selecting the context menu [ Delete ]. The deletion flow after the deletion operation is executed depends on the status of the target Fusion node.

The target Fusion node has no reference
After performing the delete operation, the target Fusion node is connected to the top node. By performing the delete operation again, the [ Delete Items ] dialog box will appear. After confirming the contents, the target Fusion node is deleted by pressing the OK button.
The target Fusion node has reference
After performing the delete operation, the [ Delete Items ] dialog box appears. After confirming the contents, the target Fusion node is deleted by pressing the OK button. Fusion nodes (as reference) connected to the target Fusion node will be directly connected to the top node.

Connect via Link

If a connection between Fusion nodes are enabled, you can drag a connector to connect a link to another Fusion node.

Delete Link

By right-clicking on a connector of Fusion node, delete a link already connected (However, a link of Fusion nodes connected to the top node cannot be deleted.) If a connector is connected to multiple links, all links will be deleted. The Fusion node that deletes its link is then automatically linked to the top node.

Undo/Redo operation

Undo/Redo operations can be performed by using the Undo/Redo icon in the toolbar. And, keyboard shortcut keys of Undo/Redo is also supported.

After selecting any Fusion node, the following context menu is displayed by right-clicking the mouse.

Save as Behavior Building Block	Save the currently selected Fusion node as a Behavior Building Block.
Suppress All Warning	Hides behavior-related warnings in Problems Browser panel.
Create Group	This menu is displayed when multiple Fusion nodes are selected. Groups the currently selected Fusion nodes.
Lock	Performs an edit lock on the Fusion node. The connector of a locked Fusion node will be grayed out and no additional Fusion node operations can be performed. Note that locking the top node will lock all connected Fusion nodes.
Unlock	This menu is displayed when the currently selected Fusion node is locked (When multiple Fusion nodes are selected, this option is displayed if all selected Fusion nodes are locked.) Unlock the currently selected Fusion node.
Force Unlock	This menu is displayed when Top node is locked and Fusion nodes connected to it are selected. Force all locks to be released.
Clone	Fusion nodes can be cloned. The cloned Fusion node will have the same name as the selected Fusion node with a number.
Copy	Copy a Fusion node. This is the same as the key command operation, Ctrl+C.
Cut	Cut the Fusion node. This is the same as the key command Ctrl+V.
Delete	Performs a delete operation on a selected Fusion node.
Paste	This menu is displayed after performing copy/cut operation. Paste the copied/cut Fusion node to the specified location.
Rename	Rename a selected Fusion node.
Change Header Color	Change the header color of the Fusion node to any color.
Restore Default Header Color	Restore the default header color specified in [ Preferences > Fusion ].

Double Click operation

Double-clicking on a Fusion node switches the display screen.

If the top node is a state machine element, display its State Machine Editor screen.
If you click on Behavior BuildingBlock Fusion node, the Fusion diagram of the target Behavior BuildingBlock's template is displayed.
If you double-click on a behavior group, its internal structure will be displayed.
