Basic Operations

Diagram Display Operations

Refer to Fusion Editor UI for an overview of the basic operations associated with the diagrams displayed in Fusion.

Diagram Bird's Eye

The Diagram Bird's Eye panel is a separate panel that provides a comprehensive overview of the entire Fusion diagram. It also highlights the section currently visible in Fusion panel, making it particularly useful when working with large diagrams. 

To open this panel from the menu, navigate to View > Fusion > Diagram Bird's Eye.

A complete documentation is available in Diagram Bird's Eye.

 

Adding a Fusion Node

New Fusion nodes can be added to any existing Fusion node that has a connector on its right side. All Fusion nodes are interconnected through links.

 

To add a new Fusion node, follow the steps below:

1. Drag the Fusion node's connector to the right and hold the mouse button
   • While dragging, a link will appear, following the mouse movement.
2. Release the mouse button at any position.
   • The Select Behavior dialog opens, displaying a list of available behaviors.
     
3. Click into the input field at the top of the dialog and start typing the name of the desired behavior.
   • As you type, the list will be filtered to help you locate the behavior more easily.
     
     
4. When you find the desired behavior double-click it to select.
   • A new Fusion node will be created and linked to the Fusion node whose connector you dragged in step 1.

Alternatively, you can browse through the list of behaviors without using the input field. The behaviors are organized in the same way as they appear in the toolbox.

Collapsing and Expanding a Fusion Node

Each Fusion Node has an expand/collapse button located in  the upper-right corner. Clicking this button toggles the node between expanded and collapsed.

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 top-left corner of the Fusion node that corresponding to that reference behavior. This icon is identical to the one displayed for the behavior in the Extra Scene tree. Click the reference icon to navigate directly to the referenced Fusion node.

Fusion Group (Behavior Group)

Fusion Nodes can be grouped together into a Fusion Group, providing an effective way to optimize and simplify the management and organization of Fusion diagrams. Groups can be renamed as desired or duplicated for reuse. Unlike a Behavior Building Block, creating a Fusion Group is faster and doesn't require template creation.

Creating a Fusion Group

• Select the target Fusion nodes
• Open the the context menu and choose [Create Group].
  
  

Navigating Fusion Groups

• Double-click the created Fusion Group to display a diagram of the grouped Fusion nodes.
• To return to the previous diagram level, either
  • Click the arrow in the upper-right corner of the Fusion Group diagram or
  • Double-click the top node in the group 

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.

1. 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.
   

   

   
   
   
2. 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.

Context Menu

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.
