How to add "Properties" to items?
Say I have an item class, and I'd like to add properties to each item. For example, one item could have the "sharp" attribute, another could have the "blunt" attribute, say a water bottle could have the attribute "water" and etc.
If you have played the STALKER CoP misery mod, you will know what I am talking about. Say I want to clean my weapon, and there is an item that has the "cloth" attribute. I can use said item to add a small repair bonus.
What would be the best way to go about doing this?
Write a script and attach it to all items which should have attributes.
In that script, define a public static enum with your desired attributes. I call it 'Types'. Each script should have a public variable of that enum type to identify a certain instance. I call it 'attribute'.
So you can check like this:
var attributeScript = item.GetComponent<Attribute>();
if (attributeScript != null & attributeScript.attribute == Attribute.Types.SHARP) {
// sharp item found
}
Additionally, you could make Attributes contain a list or an array of those enum values so you can have multiple attributes per item without having to attach many scripts to a prefab.
If you are familiar with bit masks or willing to learn bitwise operations you have more options and can make this super performant. You could use the [Flags] attribute on that enum and store the attributes as bits of an integer. Or if you have more attributes than can fit in an int, use the BitArray class
