SyncedVar hooks

[angusmf]

One of the handy things in HLAPI syncvars is that you can define a hook for them to invoke. Can we get the same?

Easy to add. Will get around to it shortly.

Thank you

I'll be busy during the weekend. Don't expect it within the next few hours.

[angusmf]

:) Have a great weekend. No rush from me. I'm starting a long trip across the US and will be working slower than ever.

Is the old value required? Or is it enough for a simple callback to be invoked when the value is updated. Going to be a bit tricky I think without a weaver to do that. Might be able to get it to work with reflection.

[angusmf]

Not sure what you mean about the old value. What the HLAPI does is invoke a callback that takes a variable of the synced variable's type. Everything else is up to you. I don't believe there's a check to make sure you actually synced the value, but I could be wrong.

[TwoTenPvP]

SyncVarHooks in the HLAPI gives the previous new value as a parameter that you manually have to set the SyncVar to. Is this needed?

[angusmf]

I don't need anything like that. My HLAPI code looks like:
[SyncVar(hook="OnSomeInt")]
int someInt;

void OnSomeInt(int newInt) {
someInt = newInt;
}

[TwoTenPvP]

Right, I understand that's the HLAPI way. But would this be alright:

[SyncVar(hook="OnSomeInt")]
int someInt;
int oldInt;

void OnSomeInt() {
//My int has changed? If I want to know the old value. I manually have to do it. Like this:
// .. code that checks someInt vs oldInt
oldInt = someInt;
}

If so, I'll get it done fairly quikcly. After I've finished https://github.com/TwoTenPvP/MLAPI/issues/3

[angusmf]

Oh, sorry I didn't understand. So it'll set the value then call the hook essentially. I can work with that.
