Fewes / PixelDot.shader

Last active May 12, 2021 04:38

Renders a screen-aligned, distance-independent, resolution-independent, pixel-perfect quad in Unity. Use it with the built-in quad mesh. You don't have to rotate or scale the mesh renderer, the shader will take care of it.

	Shader "FX/PixelDot"
	{
	Properties
	{
	[NoScaleOffset] _MainTex ("Texture", 2D) = "white" {}
	_Color ("Color", Color) = (1, 1, 1, 1)
	_Size ("Pixel Size", Range(1, 64)) = 1
	}
	SubShader

	_Power ("Power", Range (1.00, 10.0)) = 1.0
	_AlphaPower ("Vertex Alpha Power", Range (1.00, 10.0)) = 1.0

	_Cull ( "Face Culling", Int ) = 2

Fewes / ScrollableEditorCameraSpeed.cs

Last active April 11, 2017 17:00

Allows you to control the scene camera speed using the scroll wheel in the Unity editor (much like UE4).

	using UnityEngine;
	using UnityEditor;
	using System.Reflection;

	[InitializeOnLoad]
	public static class ScrollableEditorCameraSpeed
	{
	static ScrollableEditorCameraSpeed()
	{
	float cameraSpeed = 10.0f;
