# Library...

I was just wondering if someone put up a library (.mod) of useful stuff... Like some missing math and such.

I've checked quickly on battle.net and found nothing.

Since I'm building my own (Hate to work without a normalize function around), I was wondering if there isn't an already existing solution, and if not, some people would be interrested?

Well, please indulge me, what kinds of math functions are in SC2 and what ones are missing that would be useful to add?

Normalize, Cross product, Dot Product, rotation, clamp/min/max...
Couple of constant like Pi, VectorI-J-K.

I also use Global To Local and Local To Global which is sometime useful to find a vector (point) relative to a specific object orientation instead of world orientation.

Since I'm a noob with Galaxy, they might be all there already and I haven't found them yet. Wouldn't be the first time it happens.

Well, Pi is just 3.14159265(...). So, it's not really needed to put it in. But I can see where it'd be helpful. I suppose you'd also want to put e(uler's constant) in there as well.

Yup, exactly.
But you know, not everybody remember the Pi as precisly as you.

As myself, I got for 3.14159. Can't manage to remember beyond that.

IIRC, I can remember 12ish digits. 3.1415926535897

"pi to 100 digits"

3.1415926535 8979323846 2643383279 5028841971 6939937510 5820974944 5923078164 0628620899 8628034825 3421170679

Alternatively you can just use the formulae for pi if you can find one that suits your needs.

However i'd love a library if anyone does one please make a big shout about it.

It'd be also nice if the simple stuff that alot of people might use was added.

I.e. Timers that count up which is simply create timer 0:00 then loop pause wait 1 second +1 unpause.

Move Players to Team 1/2/3

I'm actually out of ideas but you know which ones I mean.

Actually, I could make something for teams An in-game team selection via dialogs...

I thought of that but it might lead to the problem of people all trying to be on the same team.

So maybe have a have a option do you want to be on a team with.

"Don't care", "Player 1,2,3,4,5,6,7,8,9,10..."

It's a bit more complex but allows friends to play together.

Or a draft system where 2 team captains could pick who is on their team. lol

Well, it would be really nice to have something like this because in some games, even if I move my friend (from my party) up to my "team" we still end up playing against each other. And I think this is because Player 2 is actually the SECOND player to join the game. Which makes no sense >_<

The old shoutbox wasn't supported anymore. We updated xenForo, so it had to be replaced.
