scalatron / Example Bot 2 - The Tag Team
Created April 23, 2012 04:54
Rough draft of a framework for simpler, more elegant Scalatron bot coding
// Example Bot #2: The Tag Team
/** This bot spawns a collection of companion mini-bots which strive to remain at a configurable
* offset relative to their master bot. The master bot runs in large circles.
*
* The master bot uses the following state parameters:
* - heading = direction it is currently traveling
* - lastRotationTime = simulation the time when the bot last rotated its heading
* - lastSpawnTime = simulation time when the last mini-bot was spawned
* The mini-bots use the following state parameters:

Beautiful Validation... Why have I never thought of this before?!
var user = {

return (
(!(username += '') || username === '') ? { error: "No Username Given.", field: 'name' }
: (!(username += '') || password === '') ? { error: "No Password Given.", field: 'pass' }
: (username.length < 3) ? { error: "Username is less than 3 Characters.", field: 'name' }
: (password.length < 4) ? { error: "Password is less than 4 Characters.", field: 'pass' }
: (!/^([a-z0-9_-]+)$/i.test(username)) ? { error: "Username contains invalid characters.", field: 'name' }
: false
