/Buybeer amount - Sal_Kings - 13.10.2009

Код:
if(strcmp(cmdtext, "/buybeer", true) == 0)
{
	new tmp[5], index;

	new length = strlen(cmdtext);
	while ((index < length) && (cmdtext[index] <= ' '))
	{
		index++;
	}

	new offset = index;
	while ((index < length) && (cmdtext[index] > ' ') && ((index - offset) < (sizeof(tmp) - 1)))
	{
		tmp[index - offset] = cmdtext[index];
		index++;
	}
	tmp[index - offset] = EOS;

	if( ! strlen(tmp) ) return SendClientMessage(playerid, 0xFFFFFFAA, "Usage: /buybeer [amount]");
	new amount = strval(tmp);

	if ( GetPlayerMoney(playerid) < (amount*50) ) return SendClientMessage(playerid, 0xFFFFFFAA, "You don't have enough money to buy that amount of beer.");

	GivePlayerMoney( playerid, (50*amount) );

	BEER[playerid] += amount;

	return 1;
}
Ok so, this is a script to type /buybeer amount.

So if you type /buybeer 3 you will get 3 beers, and you will loose 150$.
This is for my RPG script btw.
The problem is when i type /buybeer ingame it does not say "Usage : /buybeer amount". Nothing happens.
When i type /buybeer 3, it says "unkown command".

Re: /Buybeer amount - _CHoz - 13.10.2009

then try this
Код:
if(strcmp(cmdtext, "/buybeer", true) == 0)
{
	new tmp[5], index;

	new length = strlen(cmdtext);
	while ((index < length) && (cmdtext[index] <= ' '))
	{
		index++;
	}

	new offset = index;
	while ((index < length) && (cmdtext[index] > ' ') && ((index - offset) < (sizeof(tmp) - 1)))
	{
		tmp[index - offset] = cmdtext[index];
		index++;
	}
	tmp[index - offset] = EOS;

	if( ! strlen(tmp) ) return SendClientMessage(playerid, 0xFFFFFFAA, "Usage: /buybeer [amount]");
	new amount = strval(tmp);

	if ( GetPlayerMoney(playerid) < (amount*50) ) return SendClientMessage(playerid, 0xFFFFFFAA, "You don't have enough money to buy that amount of beer.");

	GivePlayerMoney( playerid, (50*amount) );

	BEER[playerid] += amount;

	return 1;
}


Re: /Buybeer amount - Correlli - 13.10.2009

That will give the warning about variable shadowing with the same name because you defined 'tmp' two times. First time with 5 cells and second time with 15 cells.

You should make a beers variable and everytime when one is purchased just do -1 to the beers.
