[nWoD] Is there a way to subtract dice from a roll in the Dice Engine?

i t may seem like an odd request, but hear me out. =) in nWod, dice rolls are modified by adding and subtracting dice.  so, a good gun may give you +2 to the roll, adding two dice.  but foggy weather may make aiming hard and give you -3, subtracting 3 dice.  the overall result would be a -1 die to the roll. is there a way to represent that in the dice engine? right now i can simulate bonuses quite well.  i give every character an Attribute called "Mod."  the character gets a token, and one of the token bars is associated with the Mod attribute.  so if i need do adjust the bonus on the fly, i can quite easily, and the character Ability macros all include rolling Mod. the problem is, this only works for bonuses, or positive numbers.  it doesn't work for 0 (which it treats as 1) and doesn't work for negative numbers, or penalties. it would be great if i could subtract dice from macros somehow. thanks!

The 0 bug should be fixed now. If you are currently in a game hit refresh. Regarding the number of dice you can do that by grouping modifiers. Example: /roll (@base+@gun-@weather)d10  If @base is defined as 5, @gun is defined as 2 and @weather is defined as 3 you get: /roll (5+2-3)d10 4d10 will be rolled. - Gauss

oh! interesting!  thanks, i'll have to give that a go! =D *edit* nice! i played around with this and it works great.  it would be nice, though, if it could handle negative numbers. now what i do is have two additional Attributes, PosMod and NegMod. so my formula looks like: (@Att1+@Att2+@PosMod-@NegMod)d10 this way i can add both positive and negative modifiers to a roll. and since both accept 0 value i can still use it for a base roll. if it could handle negative numbers, though, i could do it with just one modifier, like so: (@Att1+@Att2+(@Mod))d10 and it would add the negative number, and hence subtract the appropriate amount of dice. just a thought, though. the current system, while requiring a couple of additional steps, does allow for better bookkeeping and lets the engine do more of the math. =) thanks again! =D

We noticed the negative number issue (thanks to your earlier post and when I went to test things) and Eric should be fixing it. I will find out if and when the fix will be in. - Gauss
