HilariousCow / AnimatorExtensions.cs

Last active January 30, 2017 17:05

Some Animator extensions I use to reduce the clutter involved in setting up a hashed call to an animator parameter

	using System;
	using UnityEngine;
	using System.Collections;

	[Serializable]
	public class AnimParam
	{
	private readonly int _hashed;//a cached off version of the hashed string
	private readonly string _paramName;//don't really need but good for debug?
	private readonly Animator _anim;

HilariousCow / CopyAssetPathContextMenu.cs

Last active November 22, 2016 15:15

Unity3d utility thing. Right Click an asset-> Copy Asset Path. - ideal for use with AssetDatabase.LoadAssetAtPath<>

	using UnityEngine;
	using UnityEditor;

	public static class CopyAssetPathContextMenu
	{

	[MenuItem("Assets/Copy Asset Path")]
	public static void CopyAssetPath()
	{
	if (Selection.activeObject != null)

HilariousCow / InteractionRaycaster.cs

Last active October 15, 2023 23:29

If you are finding that PhysicsRaycaster isn't working when you use Cursor.lockstate (i.e. an FPS game), use this instead.

	using System;
	using UnityEngine;
	using System.Collections;
	using System.Collections.Generic;
	using UnityEngine.EventSystems;

	//I used ILSpy on the Unity UI dll to copy out the Physicsraycaster code and fix where the ray eminates from (in this case, always the center of the screen)
	public class InteractionRaycaster : PhysicsRaycaster {

	[Range(0.0f, 0.5f)]

HilariousCow / Example use

Last active August 12, 2021 23:39

AnimParam TidyUp code - so that your controller scripts aren't dripping in hashed versions of Animator parameters.

	class MyControllerComponent : MonoBehaviour{
	Animator _anim;
	AnimParam _myTrigger;
	void Awake()
	{
	_anim = GetComponent<Animator>();
	_playbackDurations = GetComponent<PlaybackDurationManager>();
	_myTrigger = _anim.AnimParam("StartThings");
	}

HilariousCow / VertexAlphaPlusColor

Last active December 16, 2015 13:14

So, blender doesn't do vertex alpha, annoyingly, which would be great, as it's a good way to mask out edges of meshs when you have other groovey effects going on the surface (think skyrim's wind gusts). This shader will just take blender's RGB values (i.e. luminescance) and use THAT as the alpha mask. It's otherwise a bog standard Texture * colo…

	Shader "Unlit/VertexAlphaPlusColour"
	{
	Properties
	{
	_MainTex ("Texture", 2D) = "white" {}
	_Color("Color", Color) = (1,1,1,1)
	}
	SubShader
	{
	Tags { "Queue"="Transparent" "RenderType"="Opaque" }

Load All Prefabs In Directory

	using System.Collections.Generic;
	using UnityEngine;
	using UnityEditor;
	using System.IO;

	public static class PrefabLoader
	{
	//So, there's no "load all assets in directory" function in unity.
	//I guess this is to avoid people using Prefabs as "data blobs".
	//They'd rather you use ScriptableObjects... which is fine in some cases,

HilariousCow / OneOneOneTwoThreeRules

Created February 28, 2015 21:33

OneOneOneTwoThree. A game for two brains. https://docs.google.com/document/d/1cR4QzCghzDRCYyJYZBySY56WjbQycyBFWEOraZJKW5k/edit

	public class OneOneOneTwoThree
	{
	bool[] Null(bool[] t)
	{
	return t;// lol
	}

	bool[] Swap(bool[] t)
	{
	bool[] s = new bool[4];

HilariousCow / Vector3Extensions

Last active July 5, 2018 15:21

Just some handy vector3 extensions I use a lot. I like using "FlatY" a lot for games on 2D planes.

	using UnityEngine;
	using System.Collections;

	public static class Vector3Extensions {


	public static Vector3 Flattened(this Vector3 vec, Vector3 planeNormal)
	{
	return Vector3.ProjectOnPlane(vec, planeNormal);
	}

HilariousCow / BoundsHelperExtensions

Created February 24, 2015 10:19

A few helpful extensions to get the render bounds (world space) of a game object, including all its children. Handy for placement at the edges of groups of meshes/text, or finding dead center.

	using UnityEngine;
	using System.Collections;
	using System.Collections.Generic;

	public static class BoundsHelperExtensions
	{
	public static Bounds WorldBounds<T>(this List<T> listOfThings) where T : MonoBehaviour
	{
	Bounds bounds = new Bounds(listOfThings[0].transform.position, Vector3.zero);
	foreach (T thing in listOfThings)

HilariousCow / IntRangeDrawer

Last active September 26, 2021 13:57

A random int range unity data type with property drawer. FloatRange version here: https://gist.github.com/HilariousCow/1d056da2e3324670a087. Adapted from http://www.grapefruitgames.com/blog/2013/11/a-min-max-range-for-unity/

	using UnityEngine;
	using UnityEditor;
	using System.Collections;
	using System.Collections.Generic;

	[CustomPropertyDrawer(typeof(IntRangeAttribute))]
	public class IntRangeDrawer : PropertyDrawer
	{
	public override float GetPropertyHeight(SerializedProperty property, GUIContent label)
	{
