It's a map from a popular licence in france. The problem would come from the fact that the tokens will go into a wall or into a secret room rather than stay in the corridor, I have already tried. That's why I ask if it's possible without snap to grid.
If it's not possible I push "ctr+I" every time I move token.
Check posts by myself and/or talk to Wolph42. It's really sad that I wrote the java code for onTokenMove 4-5 years ago, but really don't know much about how the darned macro parts work together. Basically, I did the java code in a test build and Wolph42(and AliasMask and perhaps 1-2 others game me some feedback as I tweaked the java code and rebuilt).
In theory, it should be possible, it will reveal at (using another macro command for revealVBL.... no sure of the name of the macro!) inside the onTokenMove "event" ONLY at the end point of the movement and POSSIBLY at each waypoint created(but I am not 100% sure). I seem to think I originally said "snap to grid is required", but I might have changed that along the way during the feature development.
