Seek and Flee steering behaviors using OpenSteer ("orbiting" result)

	// function init()
	seekVehicle = new SimpleVehicle();
	seekVehicle.setPosition(Math.random() * displayWidth, 0, Math.random() * displayHeight);
	seekVehicle.radius = 10;
	seekVehicle.maxForce = 800.0; //steering force
	seekVehicle.maxSpeed = 300.0; //velocity
	seekVehicle.speed = 100;
	seekBoid = this.addBoid(seekVehicle, 0x00CC00);

	// function update(currentTime:Number, elapsedTime:Number)

Their bracket placement and indentation is like some sick, twisted joke meant to confuse and torment me. (from http://opensteer.svn.sourceforge.net/viewvc/opensteer/trunk/plugins/Soccer.cpp?revision=181&view=markup ) It looks like the only problem is the "else" on line 14. Wrong, keep looking and it will start hurting your eyes.

	if(collisionAvoidance != Vec3::zero)
	applySteeringForce (collisionAvoidance, elapsedTime);
	else
	{
	float distHomeToBall = Vec3::distance (m_home, m_Ball->position());
	if( distHomeToBall < 12.0f)
	{
	// go for ball if I'm on the 'right' side of the ball
	if( b_ImTeamA ? position().x > m_Ball->position().x : position().x < m_Ball->position().x)
	{

IQAndreas / require-clean-git-index.sh

Created February 16, 2013 21:22

Shell function that requires that a GIT index is clean before running a command. The script allows modified or untracked files to exist in the repository, so long as the index is empty.

	function require_clean_index()
	{
	# TODO: Allow to manually set which git directory

	git diff-index --quiet --cached HEAD
	if [ $? -ne 0 ]; then
	echo "This command requires a clean index. Please reset or commit changes and try again.";
	exit 2;
	fi
	}

IQAndreas / EntityFishHook.java

Created February 14, 2013 15:48

Partial from MineCraft decompiled source - `EntityFishHook::onUpdate()`

	if (this.ticksCatchable > 0)
	{
	--this.ticksCatchable;
	}
	else
	{
	short var28 = 500;

	if (this.worldObj.canLightningStrikeAt(MathHelper.floor_double(this.posX), MathHelper.floor_double(this.posY) + 1, MathHelper.floor_double(this.posZ)))

Created January 20, 2013 15:01

Odd but valid syntax for retrieving keys or values from an object

	// Originally by @pleclech
	// via http://pastebin.com/1MDyFVJA

	var o:Object = { foo:"bar", hello:"world", one:"one", two:"two" };

	var values:Array = [];
	for each (values[values.length] in o);
	trace(values); // world,one,two,bar

	var keys:Array = [];
