How to convert "const String:var[]" to new syntax
 
Just started using smlib, following function:

Code:
stock Client_HasWeapon(client, const String:className[])
When adding it to my methodmap (which uses the new syntax), I try the following:

Code:
        public bool has_weapon(const char[] weapon) {
                return Client_HasWeapon(that, weapon);
        }
However, the compiler complains of "tag mismatch". What is the right want to represent it with the new syntax?

const char[] className should work fine unless you have a mistake some where else in the code that you're not posting.

What's the declaration of "that"

Code:
return Client_HasWeapon(view_as<int>(that), weapon);
?

WildCard65's and my replies are just okay for that purpose.
WildCard65's advice would make OP realize that that is in fact not an int therefore throw a "tag mismatch" warning, and mine was to reference to that as in int.

While, your advice is helpful and could potentially be the solution to the warning, I was just asking out of curiosity more so then as a "hey, maybe you should check". By having the declaration of "that" posted would help us determine the TRUE and appropriate solution as here's the list of potential reasons:
  • "that" is not an int
  • Compiler bug

Looks like smlib's function isn't returning a bool while your method is.

Hmm however it does return a boolean. Could old syntax do that without the right return type?

Re: How to convert "const String:var[]" to new syntax
 
For reference, I had the following code:

Code:
#define that view_as<int>(this)
Since I somewhat dislike the `view_as<int>(this)` line and I'm used to using `that` a lot in JavaScript (at least, until arrow functions become more widespread). I imagine it is a bug with `smlib` where it doesn't include the return type `boolean`, but it does seem to return anyway.
