Hi all, in my module (under construction), I have a map and 2 sigle pieces P1 & P2 in my [Game piece palette]. Each [single piece] have a [Property Sheet] called with a menu xxxx (CTRL+A). I set 2 [Definition of Player Sides] : SIDE1, SIDE2. My need : > > if I play SIDE1 : - I can see P1 and his [Property Sheet]. I can modify the [Property Sheet]. - I can see P2 but not his [Property Sheet]. I can’t modify the [Property Sheet]. I can move P1 and P2 on the map. > > on the other hand, if I play SIDE2 : - I can see P1 but not his [Property Sheet]. I can’t modify the [Property Sheet]. - I can see P2 and his [Property Sheet]. I can modify the [Property Sheet]. I can move P1 and P2 on the map. Thank you for help ! ---

That’s OK, i find the [Restricted Access] ! But, now, how a NEUTRAL single piece could change to SIDE1 or SIDE2 (mercenaries for example) ? How can I associate a “Player Side” with a [Global Property] ? \>\> if I switch a this global property, the side change for this piece… How can I manage that ?
