From the toolbar, you can also open up the Graph Console, the Graph Explorer, as well as the Graph Refactor windows with the relevant buttons each.
The selected node’s options/settings and parameters will show up into this popup panel if a node is selected. This panel is not shown if no node is selected. At the top, the node help will show if the relevant preference is turned on, as well as common options for the node’s name, tag and comments. Clicking on the header of the panel will minimize/maximize it. Furthermore, clicking on the small icon on the top left of the panel, will open the panel on an external separate window.
If a node has a task assigned, the task inspector is also shown here.
The variables of the GameObject Blackboard as well as the Graph local Blackboard will show here. Clicking Add Variable will open up the relevant context menu for adding a new variable. Clicking on the header of the panel will minimize/maximize it.
This is where everything takes shape. Right-clicking in the canvas will show a popup for adding new nodes. Either behaviour tree nodes, FSM nodes, or Dialogue Tree nodes depending on what you are working with now.
All nodes have a title name or icon and show some information as of what they will do. One node is always marked as “START”. This is the first node to execute when the graph is strated. You can change the start node by right-clicking on the node and select “Make Start”.
