Binding variables to properties is a great way to speed up your workflow. In practice, a variable bound to a property means that the variable represents that property and acts as a “bridge” to it. As such, whenever you get the variable value you will instead get the bound property value and when you set the variable value you will instead set the bound property value.
A blackboard variable can be bound to any property of any component on the same gameobject where the blackboard component is attached on. To bind a variable to a property, you simply have to click the variable options button, and select the property you want to bind it to!
Alternatively, if you don’t already have a created variable, you can directly create a bound variable through the “Add Variable” button menu.
