basically need to explain this line by line

[quiet sinew]

it makes sense in my head but dk how to explain it

the highlighted bits

[molten grove]

public static public makes it accessible from other scripts, static makes it so you can directly get it with myClass.myVariable, Action is the type, OnTargetHit is the name

[molten grove]

OnTargetHit?.Invoke(); i think this checks if its null with the ? if its not then it invokes the action

[quiet sinew]

I've said Action is an interface for any method which has no return and no input parameters, is that ok?

[peak haven]

Action is not an interface, atleast not in the literal form

[molten grove]

Score is a property, the variable itself is static, but you can only set it privately in this script

[molten grove]

Target.OnTargetHit just subscribes and unsubscribes from the Action

[quiet sinew]

ahhh, that makes a lot more sense

[quiet sinew]

wait so is OnTargetHit? basically a bool?

[molten grove]

its an Action

[quiet sinew]

so would I even need that line of code, since when the object gets hit it should immediately invoke the action anyway

so it shouldn't have to check if it's null

[peak haven]

It is fine to have the null check there

Just to be sure

This 🙂

[quiet sinew]

just out of curiosity how would I actually get it work without the null check?

[peak haven]

You could just remove it

[quiet sinew]

oh

[peak haven]

But then you risk getting null

[quiet sinew]

u mean the "?"

[peak haven]

Yes but why do you want to remove it?

[quiet sinew]

not for this object

but was just curious

i need to deliberately create errors

[peak haven]

It doesn't hurt to have it there 😛

[quiet sinew]

for my project cuz its expected of me

xd

[quiet sinew]

so if let's say if I was creating a timer, I'd have to make sure the score isn't incremented after the timer which I can do by unsubscribing from the action right?

i think that's correctly worded

yeah, so I won't be invoking this particular action to increment the score

once it's unsubscribed

correct?

[peak haven]

Correct

[quiet sinew]

ye

[peak haven]

The method with Invoke would get called, but since you unsubbed the other method it would not increment

[quiet sinew]

ah, I guess it works that way for now

but I appreciate it y'all 🙏 thanks so much for ur time

[peak haven]

Np, good luck!
