New SA-MP Functions

These functions aren't rocket science code. Just adds some functions which new coders might find difficult to write.

Nice, some functions are interesting.

Re: functions.inc - Adds new natives for scripters. - OneDay - 28.12.2017

They are not natives only plugins add natives. and this is wrong: 0<=plaerid<=MAX_PLAYERS

why not:

PHP код:





stock bool:IsPlayerPassengerAiming(playerid)

{    

    return GetPlayerCameraMode(playerid) == 55 && 22 <= GetPlayerWeapon(playerid) <= 38 && GetPlayerState(playerid) == PLAYER_STATE_PASSENGER;

}

}

What's wrong with the current method, though?

Anyway I don't think natives are just added by plugins.

I'm also not sure why this is wrong -

Yes:

PHP код:



native IsPlayerPassengerAiming(playerid);

Код:

Script[gamemodes/aiming.amx]: Run time error 19: "File or function is not found"

pawn Код:

0 <= playerid < MAX_PLAYERS

EDIT: OneDay beat me to it, damn!

Alright thanks, didn't knew that.

Just as OneDay says, you're not truly creating native functions. As the PAWN Language Guide says:

Код:

The only means that a pawn program has to manipulate objects in the host application is by calling subroutines, so called “native functions”, that the host application provides.

Plugins allow you to register "subroutines" to the host application (the samp server). A PAWN script cannot create native functions. It needs native functions that the host application provides to it.

Yes, thanks. Fixed the title.

PAWN has short-circuiting. Your code calls 3 functions then checks. My code calls 1 function then checks then may not call another.

Thanks for that, Optimized the code.
Thanks again.
