How do I…

What is the expected result

there’s a scene variable Turn that i need to toggle between 1 and 2 using a button, and a text box that displays current value of Turn.

What is the actual result

nothing happens.

What’s happening is that the first variable sets the variable from 1 to 2. However, this meets the second event’s conditions and subsequently subtracts 1 from the variable, setting it back to 1.

To fix this, get rid of the 2 subevents, and add the following action to the “Button_EndTurn” event:

“Change the variable Turn: set to mod(Turn + 1, 2) + 1”

This uses the modulus operator to flip between 1 & 2.

Thank you for replying, but that didn’t work either, counter still stuck at 1. I see what you mean about my original post. shouldn’t this work then? what am I missing? (it also doesn’t)

Nope. It’s creating exactly the same scenario as before. All that’s required is 1 event with 1 condition and 1 action. The only condition you need is:

And the only action will be

“Change the variable Turn: set to mod(Turn + 1, 2) + 1”

There’s no need for anything else.

I tested it and it doesn’t work.

mod(Turn + 1, 2) + 1

(Turn=1)
mod(Turn + 1, 2) + 1
mod(1 + 1, 2) + 1
mod(2, 2) + 1
0+1

I had to Google it bc mod() drives me crazy.
This works.

Turn = mod(Turn, 2) +1
