To make a coin system there is 3 key bits of code you need
Setup
Under options -> Init Script
You would want to add this
Start coins at 0. Will reset each time you load the tease
To give coins
add an "Eval" action
Note that the number is how much to add. It could be any number
Check for coins
To react to how many coins you have add a "If" action
This will do the "then" actions only if you have 10+ coins
It will do the "else" actions if have 9 or less coins
Show how many coins you have
In a "Say" action
Press the "<>" button
Put in "coins"
This will be replaced with the number of coins
In a "Choice" action
at the bottom if you tick "Visible"
You can show a button only if you have coins
EG only show if you have 3+ coins
Also
> < >= <= all work.
So you can check you have less then a number of coins if needed
I have made a quick demo project with a coin system added
