I looked at the other post about skill shops with its own currency but didnt find my answer.
What I'm looking for is a sepearate shop from the default that sells armor and weapons to sell but instead of using gold (the default currency) I want to use a new currency to pay for the items called reward points. (If any of you played world of warcraft; I'm talking like honor points and Pvp reward shops.)
EDIT: I figured out how to get around this, I instead developed a ranking system and each rank will allow acess to different shops, you gain ranks by killing monsters that originally would have given reward points.
Can't you do this workaround...?
Make a variable that stores your "Reward Points".
Make a variable that stores your current gold.
Make the gold that the player has all the way 0, then give the player your "Reward Points" gold.
Now you can simply do a regular store business...but then the items would be dirt cheap when selling...:/
Unless you can make some items non-sellable? o_o
Just pointing out ideas.
