Operator overloading - Dabombber - 21.07.2009

I can't seem to get this to work correctly,

[code=pawn]#include <a_samp>

stock Somethingperator--(Somethingper)
return Something_per - 1);

stock Somethingperator++(Somethingper)
return Something_per + 1);

public OnFilterScriptInit()
{
new Something:a = Something:5, Something:b = Something:5;
a++;
b--;
printf("a = %i, b = %i", _:a, _:b);
return 1;
}[/code]

gives

but if I just have the decrement operator and not the increment operator it gives the expected value. Am I doing something wrong or is this a compiler problem?

I don't see any sense in here, ++, -- operators are already done in float.inc include.

For floats, this is for a different type.

Re: Operator overloading - Correlli - 21.07.2009

They can be used for integers, too.

Re: Operator overloading - Dabombber - 21.07.2009

Everything in pawn is an integer . The only reason floats work at all is because the operators are overloaded to use functions instead of the default operators. You can make your own type with your own operators which is what I'm trying to do but it doesn't seem to work properly.

Does it?

Edited: seems +(-)= need to overload, too.
Edited2:You don't need to overload if using operator as integer does

You should know more about PAWN

I'm sure i know more than you probably, no need to tell me this.

Re: Operator overloading - Correlli - 21.07.2009

You started it, but i don't want to argue with anyone, so quit it.

Re: Operator overloading - Dabombber - 21.07.2009

I was wondering why floats worked and mine didn't so I tried

[code=pawn]#include <a_samp>

public OnFilterScriptInit()
{
new Float:a = 5, Float:b = 5;
a++;
b--;
printf("a = %.0f, b = %.0f", a, b);
return 1;
}[/code]

and got

so there's a pretty massive bug somewhere in the compiler.
