error 033: array must be indexed (variable "-unknown-") - quagga - 23.04.2012
I'm getting the following error message on each if(tgate line:
error 033: array must be indexed (variable "-unknown-")
The command and what I'm trying to do is pretty self explanatory. This is the first time I haven't been able to debug something by myself so any help is greatly appreciated. I've tried using format() too with no luck.

You can't compare strings in PAWN with ==. Use strcmp(), it returns 0 if both strings are the same:
pawn Код:
//Returns 0, success:
strcmp("something", "something");
pawn Код:
//Treated as a integer/char:
new tgate;
//Treated as an integer/char array, we can store strings in there:
new tgate[32];
pawn Код:
CMD:agate(playerid, params[]) {
new tgate[32];
if(PlayerIsL3A(playerid) == 1) {
if(sscanf(params, "s[32]", tgate)) return SendClientMessage(playerid, -1, "USAGE: /agate [gate]");
if( !strcmp(tgate, "a") ) {
if(GateO[0] == false) {
MoveObject(Gate[0], 120.81, 1942.33, 21.63, 2.00);
GateO[0] = true;
} else if (GateO[0] == true) {
MoveObject(Gate[0], 134.67, 1942.33, 21.63, 2.00);
GateO[0] = false;
}
} else if ( !strcmp(tgate, "b") ) {
if(GateO[1] == false) {
MoveObject(Gate[1], 96.93, 1925.09, 18.22, 2.00);
GateO[1] = true;
} else if (GateO[1] == true) {
MoveObject(Gate[1], 96.93, 1922.42, 18.22, 2.00);
GateO[1] = false;
}
} else if ( !strcmp(tgate, "c") ) {
if(GateO[2] == false) {
MoveObject(Gate[2], 286.00, 1834.60, 19.99, 2.00);
GateO[2] = true;
} else if (GateO[2] == true) {
MoveObject(Gate[2], 286.00, 1821.38, 19.99, 2.00);
GateO[2] = false;

if you only intend to use a single letter to name the gates, you could use sscanf's c (character) specifier.
pawn Код:
new tgate; // not an array
if(sscanf(params, "c", tgate)) ...
switch(tgate)
{
case 'a', 'A': {} // Note: single quotes!
case 'b', 'B': {}
case 'c', 'C': {}
}

Ah, okay. Thanks guys! Appreciate the help... I've haven't run into string comparison in pawn yet and I'm used to PHP.
Thanks again!
