Keypad Input simulation - 8th digit glitch

That actually appears to be a bug in how Storyline is adding to values over 7 digits. With multiplication alone, the number can extend to 17 digits. If you add anything to a number over 7 digits however, even adding 0, the number gets truncated and just increases by a factor of 10. Probably some kind of rounding error in the internal math. I'm kind of suprised that this would still exist after this long.

I tried some variations on the calculation, but they all ended up with the same result. The fix for this would be to use a JavaScript trigger to add the values. Create another numeric variable called keypress. Use it to hold the key value clicked by the user (0 to 10). Then, create one more true/false variable called triggerAdd.

Now instead of using the multiply by 10 and add 1 triggers for each key click, add the following JavaScript triggers for each:

Finally, create the following Execute JavaScript trigger:

Using this code:

let kp = Number(GetPlayer().GetVar("keypress"));
let val = Number(GetPlayer().GetVar("INPUT_DRIVER_ID"));
val = val * 10 + kp;
GetPlayer().SetVar("INPUT_DRIVER_ID", val);

The remaining triggers should be OK.

Hi Diarmaid! I ended up using JavaScript to create my numeric keypad interaction. It was helpful to see how other people approached it, and that led me to trying a few things (including my JavaScript solution!). I'll add a demo Storyline file here so you can check it out!
