@JulesV The problem is that the different positions the event object holds are related to the node when you hover it, and the whole tile when not on a node...
This makes the tracking impossible. There might be another solution that would allow to discriminate if on a node or not, but I am not aware of...
Or do the same as for the y position, using the frequency from the module that you convert to a 0-1 position then multiply with the FoaltingTile witdth
