Hello davmac, please check out this scenario. You might not understand what it is about but that doesn't really matter. If you compare the applet and html 5 version, you will immediately see the difference. The lines do not match. They should connect the circles which they do in the applet version, but in the html 5 version they don't... instead, I can't even see a pattern... The source code is available, the code of the lines is in the "Verbindung" class. They are added to the world after the circles (= Towns = "Siedlung") are added. Thanks, Hippo Related to this discussion, too bad I can't just write it there...
