Sup everyone, I try to implement macro buttons on the character sheet to make the rolls easier. The problem is the current macro's options in Roll20 canot make it. The roll system is a bit similar to Earth Dawn. Carac = 2 -> Roll 1d4 Carac = 5-> Roll 1d10 Carac = 8 -> Roll 1d20 Carac = 3 -> Roll 1d6 Carac = 6 -> Roll 1d12 Carac = 8 -> Roll 1d20+1d4 Carac = 4 -> Roll 1d8 Carac = 7 -> Roll 2d8 Etc. (Carrac = 1 no dice) after that, you just add your skill level. For exemple, If you want to fire with a weapon : you have 4 in agility and 3 in firing ability. Roll 1d8 + 3 So my actual (in work) macro : /roll @{selected|AGILITY}d???+ @{selected|FireAbility} (I try with basics macros, i'll make the buttons later) Do you see my problem ? I need to find a way to take the carac value and roll a dice in function of that value. I have basis in JS, but not enough apprently to merge it with Roll20 API system. So, Thanks to any help
