Reroll just once?

I'm updating my pathfinder macros and I'd really like to have 1d20r>18 only reroll ONCE, no matter what the next number is. I'm using HoneyBadger's powercards script if that means something can be shoved in there to help.

At this time there is no way to reroll once without using the API. What some people are doing is to put in a "Crit: [[18+modifiers]]" section and then reroll manually if the attack roll equals or exceeds the crit value.

Yeah. I've been doing a second 'crit confirm' section and I was hoping to do something more elegant. Since I *am* using API....

I don't know the API'language, but logically couldn't you do a basic if/then/else? assign the initial roll to a variable if variable is greater than 17, assign that variable a new 1d20 roll else variable doesn't change return the value of variable, whether it changed or not #pseudo BS code, DEFINITELY not correct syntax function (CritThreat) ; { varRoll = 1d20 If (varRoll > 17) Then ( varRoll = 1d20) Return (varRoll); }

You definitely can. The real question is how you want to interact with it. // Mark G's pseudo code in javascript: var rerollThreats = function (critThreat) { var theRoll = randomInteger(20); theRoll = (theRoll >= critThreat) ? randomInteger(20) : theRoll; return theRoll; };

Wow on this note for D&D 5e, I need one for rerolling 1s and 2s once. (Takes in a # for number of die, and takes in a # for number of sides to each die) Then I also need one which turns 1s into 2s. (Takes in a # for number of die, and takes in a # for number of sides to each die) Totals it up, called by a command !, and bam, two minor issues (very minor) issues I have remaining for 5e.

Right. That's leaving out the whole "how you want to interact with it" part. If you want to pass it as a die mechanic to any existing scripts, it's not going to work correctly. For example, it would be easy to write an api script for: !rollWithRerollThreatOnce 20 17 which would roll a d20, then reroll it once if it was 17 or greater. It would be hard to fit that into an HB Powercard because the dice system for HB Powercards don't understand a syntax for this.

Ah, I see, oddly enough the first one is just a display as a roll, the latter (1 -> 2s) is eventually going to be merged with the 5e Powercard system once it is done.

It's possible to add dice syntax of a sort to the powercard script, as shown by the highlighting of high/low numbers. I just need to expand on that system and figure out how to make it more robust, but as I've said elsewhere... I'm a little burnt out on scripting right now and have other things occupying my attention.

If you roll 20, 10 and only display the 10, it would be pretty useless for crits.

If you roll 20, 10 and only display the 10, it would be pretty useless for crits. Good point. I was just translating the pseudo code, but you're absolutely right. Maybe something like: // Mark G's pseudo code in javascript: var rerollThreats = function (critThreat) { var roll = randomInteger(20), res = { first: roll, second: (roll >= critThreat) ? randomInteger(20) : NaN, value: 0, rerolled: false }; res.value = (res.rerolled = !_.isNaN(res.second) ) ? res.second : res.first; return res; };

You have a typo in your ternary condition =P

Thanks! Fixed. =D
