here's some real help, not people saying figure it out for yourself:but i won't give you a full script
try something that has playersaysnumber
like this:
if(strcontains(#c,donate)){rupees=rupees+playersay snumber}
you would have to add A LOT, but i can't give you a full script =\ sorry. try making it so the player has more than 0 rupees, and they lose rupees when they say it you also might want something to display the rupees:
while(rupees>-1){message #v(rupees)}
would work
not a full script though, sorry, you should learn from this, not copy it and paste it, even though you will
