The FlowScript Controller

The most important component of FlowCanvas, is the FlowScriptController component. As the name suggests, this component is responsible for controlling a flowscript and you have to add it on a game object that you wish to be controlled by a flowscript. Although this is not really mandatory, it’s the easiest and the most suggested way to get started quickly. Once you have added the FlowScriptController component on a game object, you will notice that another component named “Blackboard” is also added. This is the place you will be creating variables, but more on these variables will be explained later on.


The FlowScriptController needs to be assigned a FlowScript, or alternatively, you can click the “Create New” button to create and assign one now. An option will pop up, asking you if you want to create a Bound or an Asset graph.

  • A Bound graph, is one that is bound to the gameobject on which the FlowScriptController is attached on. As such, this allows you to have and assign scene object references within the various nodes of the flowscript directly.
  • An Asset graph, is one saved as a .asset file within your project. The benefit of doing this is that it can be used and assigned amongst any number of different FlowScriptControllers if you so require, but the downside is that because it is an asset, you can’t have scene object references within the nodes of the flowscript.

Creating a Bound graph is the recommended type in most case, but don’t worry about it too much because you are able to convert between the two at any time you wish.


Once you have created a flowscript through the button, the editor will show up immediately.
