gravity you say, I did that in 3d a while back
you can do something like this: (pseudocode)
[code]
//object is the thing being affected by gravity
difference = normalisedVector2(gravitySource.origin - object.origin);
distance = distancev2(gravitySource.origin, object.origin);
distance *= distance; //square it
object.momentum += difference * (arbitraryValue / distance);
[/code]
then add the objects momentum to its origin

Okay, I don't get that...
In a 2D space, what's the difference between... well, an objects origin subtracted from another, and their distance apart?
'distancev2' sounds like a function which returns the difference between two objects' origins as it is...
Also, is this point gravity? I was going for 'fall to the floor' gravity, but then I changed my mind and decided I wanted it to be point gravity 'cause I could develop on it...

origin minus origin gives a two-part vector showing the x/y difference, and the distance between two origins gives a single number.
distancev2 just calculates the single number for a distance between them

Scavenger has better tactics, it scavenges for health and then ammo until it has full of both, then uses all of its ammo at once on the other bot so it doesn't have time to heal.

Make a fancy screensaver.
[QUOTE=noctune9;18099656]Make a fancy screensaver.[/QUOTE]
I've always gone for the blank screensavers.
It seems the opposite of sensible to use a 3D or somehow processing intensive screensaver since it's the thing that shows when you aren't using your computer. It wastes power and produces heat :/
But I don't have a better idea :(

That is really awesome!
Robert64: Very nice, it's like we're working on two twin projects!
Scavenger is canny!
I noticed your scripting language is a bit unusual, Had I noticed your post earlier, I would've advised you to use something like [url=http://code.google.com/p/as3scriptinglib/]this[/url] instead, you can have a generic bot class and pass it as the "this" object to the bot's code, which would run as standard ECMA Script.
Great work, I'd write some kickass AI right now, but I'm a little busy with my own project. :eng99:

Jesus, can't you assign some more things in a single line? Those first couple are a bit short.
You're also doing a lot of pattern matching, that can be done much simpler.
In processdata you're calling lower on the same strings over and over, seems awfully redundant.
For a supposed highly modular bot, you've got a lot of hard coded responses in that parsing method of yours.
And finally, a single file for the whole parser / bot control thing is insane, write your IRC library separately as a module.

You can abuse "move: forward;" to create faster bots :).
[code]
move: forward;
move: forward;
move: forward;
[/code]
[QUOTE=Aertz;18103141]You can abuse "move: forward;" to create faster bots :).[/QUOTE]
The game runs 4 commands per frame, so you can put four "move: forward;"s or "shoot;"s in a row for maximum speed. This is a valid tactic (my bot #3 uses this for shooting).
But if you do that you're sacrificing if statements etc, so your bot isn't as smart. You have to balance speed and intelligence to make the best bot.

Ahhh nice.
Is there a way to get the closest distance of a health or ammo?
[QUOTE=Jawalt;18103487]Is there a way to get the closest distance of a health or ammo?[/QUOTE]
[code]health_x // x position of closest health
health_y // y position to nearest health
health_dir // relative direction to direction of bot to nearest health
health_dist // distance to nearest health[/code]
And same for enemy_ and ammo_
Be careful, if statements are very strict. Separate each part with a space like this:
[code]if: health_dist + 16 < ammo_dist * 2;[/code]
And you can only have one operator in the middle out of:
[code]> = <[/code]
edit:
And valid colours are as follows ;)
[code]white, grey, black, red, orange, yellow, green, blue, purple, brown, pink[/code]
[QUOTE=Jawalt;18103487]Is there a way to get the closest distance of a health or ammo?[/QUOTE]
Without knowing exactly what you want can I suggest the following.
Check all of the items within a range of co-ordinates to see if they match what you want (maybe a range of two or three rooms if doing a roguelike for example). If there is more than one then find which is closer, if there aren't any then make the range slightly larger and repeat until you have the closest desired item.
Or you could simply go through every item of the desired type and calculate the distance to it and take the one with the shortest distance.
That's the best I can suggest though having never done anything similar and not knowing what your making (haven't really been reading all the posts recently).

My latest robot stands still on start and dies.
I made what I believe to be a completely unbeatable robot (like 90% of the time) it's code is as small as possible with as little logic as possible, and it's only goal is to collect ammo then kill. It's called ScavangerAdvanced.
