Counter moved by card but only for a side

I want a counter is moved by a card when this counter show his frontal side, not when the reverse side is showed.

Is this possible?

Yes you would have the card send a Global Key Command (to be picked up by a trait in the counter, causing it to move), and you could use the GKC’s matching expression to only match counters that are face-up. How to check if a counter is face-up depends on how you have the counter configured – either checking the built-in level property of the counter or checking the same thing its “level follows expression” field checks.

Thanks, this works :smiley:
