I converted my script from DCMD to ZCMD and now i've gotten this wierd bug, when i type a command like /Flip [ID] For example, and i leave the id field blank, it picks ID 0 automatically.

use sscanf instead of strlen..
i will give a quick example remove strlen(params)
and define player1 before this and add

pawn Код:

if (sscanf(params, "ud", player1))

I have a ton of commands how do i replace them in the easiest way?

Update your SSCANF! Inc and plugins

[RedFusion]

Why would that help? I dont even have Sscanf yet.

[LaGrande]

download it, or else you will suffer from this bug

[RedFusion]

But why would i download it when i have STRLEN and i dont know how to convert?
I need to know how to convert to Sscanf, not a quick example, im not familiar with this.

Because of a bug in CallLocalFunction, you can't pass empty strings. Therefore, ZCMD passes "\1" instead of an empty string.
A macro is provided to check if the params are empty:

pawn Код:

// WRONG:
is (!strlen(params)) {
    // no params..
}
// CORRECT:
is (isnull(params)) {
    // no params..
}

Alternatively, you could make a macro and add it on the top of all commands:

pawn Код:

#define NULL_PARAMS(); \
    if (!isnull(params)){}else{params[0]='\0';}

// Usage:
CMD:blabla(playerid, params[]) {
    NULL_PARAMS();

    // code..
}

CMD:blabla(playerid, params[]) {
    NULL_PARAMS();

    // code..
}

CMD:blabla(playerid, params[]) {
    NULL_PARAMS();

    // code..
}

What if i have 3 parameters in a command, and the first 2 are critical, the third one fills up automatic if nothing is entered. For example: /Weapon <Playerid> <WeaponID/Name> <Ammo> Does that method work for this?

"isnull" will only return true if the string is empty, i.e. no params. Everything else should work as it did before.
