This module adds logic functions to the roll formulas.
All functions operate based on the assumption that zero is false and non-zero is true. All functions return 1 for true and 0 for false. This is convenient for multiplication.
The functions include
eq(a, b) (equals)
ne(a, b) (not equal),
gt(a, b) (a greater than b),
gte(a, b) (a greater than or equal to b),
lt(a, b) (a less than b),
lte(a, b) (a less than or equal to b),
and(a, b, ...) (all arguments are non-zero),
or(a, b, ...) some arguments are non-zero.
pick(condition, then, otherwise). The second and third parameter can be omitted, they will default to 1 and 0. The inverse is
unless(condition, then, otherwise) that inverts the condition, i.e. picks
then if the condition is false.
These can be used wherever rolls can be made/evaluated. If you give a dagger this damage formula
1d4 + @mod + pick(gt(@abilities.int.mod, 1), 1d12), the dagger will include an extra 1d12 in the damage if the user's intelligence modifier is greater than 1.
Note that the functions do not change dice rolled. All dice in the statement are always rolled, the conditionals just change which numbers are included in the final calculation. This limits their usefulness in some cases, while they are useful elsewhere.
