I need help making shops for buying things I already have the money established.

Have the items people can buy in the shop as sprites, and call them up using a broadcast when the person enters the shop. You will need to make a variable, but I assume you have, if you have the money.

When [Potion_Red] clicked
change [money v] by [-1]
say [You bought potion!]

In that example, the person would lose 1 of their money for buying the "potion" and then it tells them they have bought it successfully.

Inversely, you could have the person sell their "Red Potion" by making it change money by 1.

Or:

When [potion] clicked
change [money v] by [-1]
add [potion] to [items v]

that way, the game remembers that you have bought it. When you need to use it, do something like:

forever
if <action happens>
if <[items v] contains [potion]>
do action involving potion
end
end
end

You also have to take into account that you can only buy someting if you have enough money, so try this:

When [potion v] clicked
if < (money) < (1) >
  say [you don't have enough money!] for (2) secs
else
  change [money v] by (-1)
  add [potion] to [items v]
end

that should work. smile
