Roll20 macros

Better automation through macros

So I’ve spent the best part of a day unlearning some bad habits when I set up the Roll20 sheets for my players.  I wish I’d spent some more time getting to grips with the documentation before I set down to create but I realise the campaign was based upon one of my first fumbling attempts at getting Roll20 to behave how I wanted.

Why Macros?

A macro is a statement that tells Roll20 to execute a string and in my case I had defined attack macros, dodge macros and damage macros.  What I forgot is that you can create a central pool of macros for all to use rather than creating them individually in each characters journal.  When I set the journals up I used the former method rather then the latter.  The downside was that as I read the documentation I learned more about how to write an effective macro and I was faced with the realisation that I would have to change it for each character that had a journal entry.

Why Change?

I changed because my players deserved better than me saying “Ah, I haven’t set that macro up yet on that character” and since I had some free time this weekend I did just that.  I scrapped the individual macros and harnessing the power of the language I re-wrote the macros while taking the time to improve them into something more functional.


So I present to you an example macro from the library that my players have access to, a simple ranged combat macro:

/em @{selected|token_name} fires my handgun!
/roll 1d10 +@{selected|Dexterity} + @{selected|Guns (Handgun)}  
+ ?{Additional Attack Bonus/Penalty?|0}
!ammo Pistol ammo

I also created them as token specific which means that you have to have a token highlighted before it will correctly execute.

The first line has the token announce the name of the token and what its doing.  The second line rolls a d10, adds the values of Dexterity and the handgun skill together before popping up a dialogue box asking if there are any other miscellaneous modifiers to add to the roll; say a situational modifier for someone that has been aiming long enough to obtain a bonus or if they are using a scope.

The final line calls a script which decreases the value of an attribute called Pistol ammo by one.  This way the player can see how much ammo they are going through as I used one of Roll20s radial buttons for this task.

There are more things to be done, but I hope that my players will see the benefits of a well written macro.

Old habits

So for the first time in a while I find myself playing in a game and its pretty good to roll the dice as a player. The game is Call of Cthulhu using the Achtung Cthulhu books and set in the early stages of the war.

Something has been playing on my mind though, despite having reasonably competent skill ratings  I seem to be failing to make skill checks; perhaps this is to be expected or maybe I have failed to live up to my tradition when starting a new game.  So I have taken steps to rectify this situation by buying a new set of dice; this time I’m going old school and have ordered a set of white inked red Gamescience precision dice.  I know its a silly superstition but you never know these dice may live up to the hype.

I shall let you know in due course if my new dice do indeed roll true and are better luck than the ones I’m currently using.
