Attributes
Attributes are key-value pairs that can be assigned to individual Marble items to represent any kind of numerical value associated with an item. Since attributes are attached to individual items they will travel with changes in ownership.
Below are a few sample Attributes and their associated point values.
Attribute Name | Attribute Points |
level | 5 |
experience | 750 |
strength | 18 |
height | 74 |
bananas | 3 |
modifier | -5 |
Note that Attributes have specific actions that allow the point values to be manipulated directly, as opposed to Tags that can only be overwritten.
The Attributes layer also includes Shared Attributes that are assigned to a group rather than an individual item. Use Shared Attributes to apply attributes to all items in a group or to save RAM costs.
