error 008: must be a constant expression; assumed zero - 3417512908 - 29.07.2018

Don't ask me such as question:"Why don't you direct use 'cmdtext' ?"
I have own reason.

Code:

public OnPlayerCommandReceived(playerid,cmdtext [])
{
	new cmd[] = cmdtext;//error 008: must be a constant expression; assumed zero
	strdel(cmd, 0, 0);
    for(new i = 1; i < MAX_TELEPORT; i++)
	{
	    if(!strcmp(cmd, TeleportData[i][CMD], false) && !isnull(TeleportData[i][CMD]) && !isnull(cmd))
    	{
    	SetPlayerPos(playerid,TeleportData[i][PosY],TeleportData[i][PosX],TeleportData[i][PosZ]);
    	break;
    	}
	}
	return 1;
}

Help,please.

You can not initiliaze a variable with another variable unless it's a constant and cmdtext isn't a constant variable.

Declare a size for your cmd array like this

Code:

new cmd[20];

Change the size to fit your needs.

And what's wrong now:

Code:

new cmd[20];
	cmd = cmdtext; //error 047: array sizes do not match, or destination array is too small

The array size you've defined is too small for cmdtext to fit, cmd's size is 20, therefore cmdtext must be defined as 20 or below. As we don't have a size for cmdtext, you can't tell PAWN that cmd is equal to cmdtext, it just won't work.

You need to use format.

Also, I don't recommend using 20 for CMD, it was just an example to tell you how it works.
