AngryAnt / DependencyInstall.cs

Last active December 30, 2015 04:29

A quick example demonstrating how unpacking logic for an asset store package could be set up to be contingent on the presence of a specific code dependency.

	foreach (Assembly assembly in AppDomain.CurrentDomain.GetAssemblies ())
	{
	string location = Path.GetDirectoryName (assembly.CodeBase).Replace (Path.DirectorySeparatorChar, '/');

	if (location.StartsWith ("file:"))
	{
	location = location.Substring ("file:".Length);
	}

	if (!location.BeginsWith (Application.dataPath.Substring (0, Application.dataPath.Length - "Assets".Length)))

Silly workaround for easy alpha scaling on the Unity Color type.

	public static Color A (this Color color, float alphaScale)
	{
	return new Color (color.r, color.g, color.b, color.a * alphaScale);
	}

	// Gizmos.color = Color.red.A (0.3f);

AngryAnt / TerriblyHackyLog.cs

Created August 7, 2013 18:04

Abusing reflection and the internal Unity player build error function to get stacktrace-less error logs. Not recommended for anything sane.

	using UnityEngine;
	using System.Reflection;

	public class TerriblyHackyLog : MonoBehaviour
	{
	void Start ()
	{
	Log ("Aaaaarrrrgh!");
	}

	public static void AddAxis (AxisDefinition axis)
	{
	if (AxisDefined (axis.name))
	{
	throw new System.ArgumentException (string.Format ("Specified axis \"{0}\" already exists", axis.name));
	}

	SerializedObject serializedObject = new SerializedObject (AssetDatabase.LoadAllAssetsAtPath ("ProjectSettings/InputManager.asset")[0]);
	SerializedProperty axesProperty = serializedObject.FindProperty ("m_Axes");

AngryAnt / Digits.cs

	{
	if (value >= Mathf.Pow (10, m_Digits.Length))
	{
	Debug.LogError ("Value overflow: Unable to display value: " + value);
	}

	if (Vector2.Dot (gesture.direction, new Vector2 (1.0f, 0.0f)) > 0.8f)
