How do you Set and Get variable and their values of any Game Object?

Unity Engine
1

I’ve been trying to find examples of this and i find nothing.

I"m a beginner so i don’t even know how to use those and most examples out there just have difficult code.

Anyway

Say i have a C# Class for some enemy and in it it has a enemyEnergy variable.

Then
I have another C# Class for the player…and it wants to check the enemyEnergy and even modify it.

Would something like this work? i dont’ know the exact unity and c# code but i’ll just make something like i’ve used in other languages.

i would do this inside one of the Player script
→ if enemy.getEnergy( ) > 10 Then enemy.setEnergy( enemy.getEnergy( ) - 1) )

i kinda did it how it’s done in Java.

is that how it works???

So in unity what are the mehtods for this

how do you do this in Unity?

Don’t stress over it since it’s not a big deal, but it’s a good idea to use C#'s best practices for this kind of thing. Instead of using getter/setter methods, C# provides access via “properties”. These look like variables, but accessing or changing them is actually a function call.

Using a property looks something like this:

private int IntValue
public int IntValue {
    get {
        return intValue;
    }
    set {
        intValue = value;
    }
}

In the example, “get” and “set” are keywords used to define the getter and setter parts of the property, respectively. If you don’t want a setter you can leave it out, or you can also make it as private (really handy - you can use this so that you’ve got a variable which is publicly accessible but can only be set internally, making for clean interfaces but elegantly minimalist code). Also, “value” is used to access the input value in a setter. Finally, you can of course do more than return or assign - for instance, in a setter it’s a good idea to sanity-check the value if relevant - but since other coders are expected to treat properties the same as they would a variable it’s best practice to put only trivial code in there.

One last note is that the example above shows what I think is considered best practice for naming style. Variables are named starting with lower case letters. If a variable is accessed via a property, then that property has exactly the same name but starting with a capital letter.
