Editing Mano a Mano:Hack and Slash (section)

==Numbers==

;None: Some modifiers can have the value "None", which is different from the number 0.  A character with 0 flight ability can barely fly, but a character with no flight ability cannot, and has a flight ability modifier of "None".  A natural weapon which is not a hand has a dexterity modifier of "None", meaning it cannot be used as a hand, while a natural weapon with 0 dexterity is a very good hand.  A sharpness of "None" means a weapon always does stun, while a sharpness of 0 means a weapon always does damage.

;Fractions: A computer game can use the same whole number and simple fractions for levels and modifiers that are used in Mano a Mano. However, if you want smaller increments, any fraction between the minimum and maximum values will usually work.

;Success Levels: If fractions of modifiers to success rolls are allowed: an action whose success level is at least 0.5 is successful; an action whose success level is between -0.5 and 0.5 is half-successful; and an action whose success level is no more than -0.5 is unsuccessful.

;Linear Interpolation
:CP values for fractions are interpolated linearly. To interpolate the CP of a modifier in the modifier range (mod1, mod2) with the CP range (cp1, cp2):
::<code>CP = ((modifer-mod1) / (mod2-mod1)) (cp2 - cp1) + cp1</code>
:To find the modifier for a CP value:
::<code>modifier = ((CP - cp1) / (cp2 - cp1)) * (mod2 - mod1) + mod1</code>

;Geometric Sequence: Many CP values are based on a geometric sequence.  The n<sup>th</sup> term of the sequence is the previous term plus n, which collapses down to: term = n * (n + 1) / 2.  To find n for a given term of the sequence: n = (sqrt(8 * term + 1) - 1) / 2.  A computer game might use these formulas or a table of CP values that are already calculated.

The default CP scale for non-negative modifiers is 100 times the geometric sequence, using the modifier as n.  For negative modifiers, the default CP scale is -100 times the geometric sequence, using -1 times the modifier as n.  The double and triple CP scale are 2 and 3 times the default CP scale respectively.

The CP of sharpness levels up to 4 is 1000 - 200 * sharpness.  If you allow sharpness over 4, (increasnigly blunt weapons unlikely to cause lasting damage) you could use the CP formula 800 / sharpness.
