Couldnt you just use defines for it?
Код:
// top
new
pCash[MAX_PLAYERS];
#define GiveUserMoney(%1,%2) pCash[%1] += %2
#define GetUserMoney(%1) pCash[%1]
#define ResetUserMoney(%1) pCash[%1] = 0
Then you are able to use those functions
instead of "GivePlayerMoney(playerid, amount)", use "GiveUserMoney(playerid, amount)"
Instead of "GetPlayerMoney(playerid)", use "GetUserMoney(playerid)"
instead of "ResetPlayerMoney(playerid)" user "ResetUserMoney(playerid)"
So you could for example use
Код:
if(GetUserMoney(playerid) < 200) return SendClientMessage(playerid, COLOR, "You dont have the cash");
GiveUserMoney(playerid, -200); // Remove 200 from the cash of the player
The item System should be easy, it could for example look like ( just an example you need to change it for your needs)
Код:
// top
#define ITEM_NONE 0
#define ITEM_CONDOM 1
#define ITEM_DRUGS 2
#define ITEM_DRINKS 3
#define ITEM_PHONE 4
// more items here
#define MAX_ITEMS 5 // increase if you use more items
#define MAX_ITEMSLOT 3 // amount of items player can carry, remember you need to save each item
#define MAX_ITEMAMOUNT 20 // the max amount of an item a player can carry
new
pItem[MAX_PLAYERS][MAX_ITEMSLOT],
pItemAmount[MAX_PLAYERS][MAX_ITEMSLOT];
stock GiveUserItem(playerid, item, amount)
{
/*
returns 0 if NOT successfull
returns 1 if successfull
*/
new
slot = MAX_ITEMSLOT;
for(new i = 0; i < MAX_ITEMSLOT; i++)
{
if(pItem[playerid][i] == ITEM_NONE || pItem[playerid][i] == item)
{
slot = i;
break;
}
}
if(slot == MAX_ITEMSLOT) return 0;
if((pItemAmount[playerid][slot]+amount) > MAX_ITEMAMOUNT) return 0;
pItem[playerid][slot] = item;
pItemAmount[playerid][slot] += amount;
if(pItemAmount[playerid][slot] <= 0) pItem[playerid][slot] = ITEM_NONE;
return 1;
}
stock GetUserItem(playerid, item)
{
/*
returns the amount of an item
*/
for(new i = 0; i < MAX_ITEMSLOT; i++)
{
if(pItem[playerid][i] == item) return pItemAmount[playerid][i];
}
return 0;
}
stock GetItem(item)
{
new
string[30];
switch(item)
{
case ITEM_CONDOM: format(string, sizeof(string), "Condom");
case ITEM_DRUGS: format(string, sizeof(string), "Drogen");
case ITEM_DRINKS: format(string, sizeof(string), "Drinks");
case ITEM_PHONE: format(string, sizeof(string), "Phone");
// Add more items here
default: format(string, sizeof(string), "Nothing");
}
return string;
}
So you can use different functions with it:
Quote:
GiveUserItem(playerid, item, amount): Give or Remove an item of a player ( returns 1 if successfull and 0 if not)
GetUserItem(playerid, item): Amount of the item in the bag ( returns the amount of the item in the bag of the player)
GetItem(item); returns the name of the item
|
So an basic exmaple could be a shop which sells Phones and Condoms:
Код:
// buy command
new
item,
amount,
string[80];
if(sscanf(params, "dd", item,amount)) // check the parameters with sscanf or strtok
{
SendClientMessage(playerid, COLOR, "USAGE: /buy [item] [amount]");
format(string, sizeof(string), "Available Items -> Phone:%d | Condom:%d ", ITEM_PHONE, ITEM_CONDOM);
SendClientMessage(playerid, COLOR, string);
return 1;
}
if(amount <= 0) return SendClientMessage(playerid, COLOR, " Wrong amount");
if(item != ITEM_PHONE && item != ITEM_CONDOM) return SendClientMessage(playerid, COLOR, "You cant bought this here");
new
bool:success = GiveUserItem(playerid, item, amount);
if(!success) return SendClientMessage(playerid, COLOR, "Check your bag, you cant put this item in the bag right now");
format(string, sizeof(string), "You bought %d %s", amount, GetItem(item));
SendClientMessage(playerid, COLOR, string);
// in the call command you could then check
if(GetUserItem(playerid, ITEM_PHONE) == 0) return SendClientMessage(playerid, COLOR, "You dont have a phone");
You could also do everything dynamic and save the stuff of the shop in other Arrays, so the things the shop sells are set in a database. Of course you need to save both the Player Items and the Shop Items in a Database and load them in order to create a Item System
