Will B. said: Hi all, Started using the Combat Master script last night, I think it's great. Just a couple of questions, as I'm still getting to grips with Roll20: Do you "start" combat master, then get your players to roll initiative? It won't let me start it, unless I have a token selected. And doesn't always seem to add my players' initiative rolls Also, I've worked out how to add concentration to a token, but my understanding is, that it should automatically flag up a concentration check, when a token takes damage, but it isn't doing that. Any thoughts? CM needs a token selected to start combat. My typical practice is to let players roll their own initiative (using a custom macro, but you could use the GroupInitiative script if you prefer), then select at least one monster and hit that play button to start CM. You should be able to select monsters and use GroupInit to start combat too (if you've selected GroupInit as your method of initiative in CM), but there are currently some issues with turn ordering when doing that, which is why I recommend the play button at the moment. I have to go back and check the con check thing, because you're not the first user to report this recently. It may be a bug with the current version of CM.
