SentinelBot

Bot development has been slow for a bit so I'd thought I contribute.

I give you: SentinelBot - the twisted offspring of s_bot, clonebot and orbitbot!

Usage:
/addbot sentinel [team index] [player name]

Example:
/addbot sentinel 0 raptor

Behavior:
SentinelBot does the following:
  • Find the designated player *anywhere* on the map (not just within sight) and will proceed to orbit that player
  • Shoot any hostile targets nearby while orbiting. It will shield itself, too.

Yes, this bot makes sure you know how to spell 'sentinel' correctly.

And yes, this bot can be transformed into a terror-bot: just specify your team with an opposing team's player :twisted:

Enjoy!

Update: SentinelBot now changes its name if used for evil
Update 2 : Updated to work with 018 scripting enginel
Update 3 : Really make it work with 018 this time
Update 4 : Really, really make it work with 018
Update 5 : Requires 019+ now

Re: SentinelBot

Cool! I never thought sentinel was hard to spell, its spelled how it sounds. I'll have to try it out later :)

Re: SentinelBot

**ROBOT ERROR*** in /Users/mycomputer/Library/Application Support/Bitfighter/robots/sentinelbot.bot ::: Script error: ...mycomputer/Library/Application Support/Bitfighter/robots/sentinelbot.bot:11: unexpected symbol near '�' -- Aborting.


EDIT: Restarted bitfighter, it worked... No clue why that error occurred.

A few comments; it uses shields if you shoot close enough to it, it should know your its friend! When you stop it should cease to circle you, in narrow passages it can be quite a nuisance, always bumping into you. Not to mention trying to destroy a mine.
