ok im making a shop in my game and i have it so when you move your curser on the item the shop info actor says how much the item is, and i also got it so when you click on item it goes i your iventory, and where it subtracts that amount, but if you don't have enuph money it still goes in your inventory and the your money amount goes negative, the thing i need to know is how to make it so it doesn't go negative and the shop info actor says somthing like,"you don't have enuph money!"

you need to setup some "if" statements, such as:
on the "buy" event (keydown/mouse button down/etc.)

if (money >= 250)
{
insert your item stuff and money subtraction stuff here;
}
else if (money <= 250)
{
insert your "you don't have enough money for that!" stuff here;
}

d, that little snippet of code would display both messages if you had exactly 250 money.

but the thing is idk how to make the "you don' have enuf money" actor

and fuzzy what wuld you put?

Whoops, good catch Fuzzy...

on the "buy" event (keydown/mouse button down/etc.)

if (money >= 250)
{
insert your item stuff and money subtraction stuff here;
}
else if (money <= 249)
{
insert your "you don't have enough money for that!" stuff here;
}
