Increment an array using an event structure

[Liddy]

Hello,

I would like to increment a numeric indicator on the front panel using an event structure ("Key Down" and "Key Up") when the space bar is pressed. I have the event structure set up, however, I'm stuck on how to show the total number of key presses in real time.

You need to accumulate the count in a shift register or feedback node, then connect the indicator to its wire.

Please attach a simplified version of your code so we can give more targeted advice.

It would look something like this.

Where does the array from the title ("Increment an array using an event structure") come in?

If you want to increment the count for key down and key up (which lets you even determine if it is currently up or down by looking at even/odd of the count ;)), I would probably do something like the following.
