 |
|
does anyone know how to simulate the log function in integer math like the ohrrpgce uses? for example, would something like this work?
script, log, value, base
(
# RETURNS THE INTEGER LOG 'value' IN BASE 'base'.
# DEFAULT BASE IS 10.
if ((n / base) >> 1) then (return (1))
if (((n / base) / base) >> 1) then (return (2))
if ((((n / base) / base) / base) >> 1) then (return (3))
# etc.
)

My 'math.hss' file is getting so large.
| Code: | define script (-1, log, 2, 0, 10)
script, log, value, base, begin
variable (result)
while (value >= 1) do (
value := value / base
result += 1
)
return (result -- 1)
end |
Always rounds down. What use is this script, you ask? log of a number to base 10 + 1 returns its length in digits, possibly useful when displaying numbers.
(rinku, ignore the difference in scripts) |

that should work.
btw, you should release math.hss with quaternion!
better: we should have a public place to post general-use scripts, and they'd be auto-added to new versions of the ohrrpgce. i could include the best script ever, maybe. here's the simplest version of it.
script, maybe
(
if (random (0,1) then (return (1)) else (return (0))
)
it's amazingly useful! you can do things like
maybe + maybe + maybe and get a weighted random number between 0 and 3, but it'd much more often be 1 or 2 than 0 or 3.
also useful for if (maybe) then (do something) for something that should happen half of the time. every game should have a maybe!

Hmm, that might be an interesting new addition to the CP update (The script uploading idea, that is). I thought about it before in the past, but totally forgot until now  . It'd be nice if there was a library that the community can freely contribute to.
But also, a while back I created a chance script that's used in a similar way as that maybe script. It's actually part of that library I have posted as a sticky. But instead of just being true or false, it would return true based on a percentage. I dunno if you'd use it or not, but you never know:
| Code: |
script, Chance, CPercent, begin
if ((random (1, 100)) <= CPercent, and, CPercent <> 0) then (
return (true)
) else (
return (false)
)
end
|
So you could have something happen 67% of the time if you wanted it to.
For that maybe script too, you could just shorten it to simply this:
| Code: |
script, maybe
(
return(random(0, 1))
)
|
Since you're just returning the numbers created by the random function in the first place 
But yeah, I'll talk to IM about adding a plotscripting section itself to CP somewhere. Script sharing is always fun  . |

i do have a percent-based version of maybe, which works much like the one you posted (the default value for the percent is 50). it's pretty useful too.
