I just went pro so I could program my way around some of the clunkiness of trying to run a Cortex Prime game via Roll20. I haven't worked with the api yet. I recently discovered rollable tables, which do a fantastic job of providing a means to add or remove dice tokens from a pool area on a map, then allow the player to multiselect and roll them--at first I thought I wouldn't need to program anything. What doesn't work out of the box is stepping up or stepping down a die-type (like from d6 to either d4 or d8, for instance). I was envisioning setting up assets and complications as visibly labeled dice to be pulled into a die pool, but some character abilities allow the dice to be stepped up/down for a particular roll. If I could swap out what rollable table the token represents, that would be ideal. It doesn't seem like I can delete a token at all, so deleting it and then replacing it with a rollable table token from a different die table (but keeping the nameplate value) doesn't seem likely. Can I actually swap out the underlying rollable table? Re: Cortex Prime: this RPG represents different abilities and gear/situational aspects relevant to a character via dice from 4-12 sided, the bigger the better. A given check will have a minimum of three dice in it from traits found on a character sheet, but there will be more as stuff happens in a scene, like the character adding beneficial modifiers such as carefully aiming, or finding a gun (each is a die they add to their pool) or taking penalties from negative mods (dice the opposition gets to roll). Assets and Complications stick around across rolls in a given scene, so stepping them up/down to either intensify them or get rid of them is very likely.
