String operations - passcode puzzle

andiliddell

I'm building a numberpad passcode puzzle, and wondered if there's a way within the actions to append a string global variable (so as you press a number button it adds that number to the current code, rather than replacing the whole string?

I'm using an AC menu to display the global string, but can;t seem to add to the global string only replace it completely?

Alternatively, having a hotspot for each number button call a custom C# script to collect the value, add it to the string and then passs this back to the AC menu element?

Any advice would be great.

In the Variable: Set Action, you can use the variable's token to combine it's value with new text. For example, if the variable's ID is 2, and current value is X, then:

[var:2]Y

Becomes:
XY
