Understand what Attributes are.
Understand how Attributes are consumed / recovered in PAT.
Attributes are the stats a character can have, such as health, resistance, attack and stamina.
Each of them is stored in an Attribute Component under the Character object or under its children.
At runtime, Character component will automatically collect all the Attribute Component under it.
Obviously, we don't want the attribute to stay at the initial amount forever. We want to modify the value during gameplay. How can we make that happen?
In the previous articles we talked about how are used to trigger and validate Action States. Apart from that, there is another usage of Tags.
We use Resource Tags to label attributes. For example, the Stamina Attribute on the penguin has a resource tag of Stamina.
With a resource tag set, an Action State can use the tag to find its attribute.
Let's look at the locomotion move set of the penguin.
In the inspector of Roll, we can see another modifier: Use Attribute Mod.
You can see it also has a Resource Tag field, and it is pointing to Stamina. This makes Roll Dodge costing Stamina every time it gets triggered. You can control the amount being cost in the mod as well. If you set the number to be negative, you will find it recovering attributes instead of consuming it.
