Small tool to generate gradient Texture2D from array of colors. (Note: maximum colors is 8, since it uses unity Gradient internally ( https://docs.unity3d.com/ScriptReference/Gradient.html ) Source:https://github.com/UnityCommunity/UnityLibrary/blob/master/Assets/Scripts/Texture/GradientTextureMaker.cs Example usage script: (attach script to some 3d object)https://gist.github.com/unitycoder/f7ea9019bb67b7042efbd08f0f4fa785

Saw interesting question here https://forum.unity.com/threads/animated-outline-effects-using-shader.600028/ and unity sprite outline https://github.com/wlgys8/Sprites-Outline + stackoverflow https://stackoverflow.com/a/16856878/5452781 to the rescue! (although this is for 2D sprite..) Results: TODO – Test how this would look with screenspace values (to keep same size even if zoomed) – Maybe could check neighbor pixel […]

Had to make an UI button clickable by multiple different keyboard keys (like enter, space, left/right shift etc.) And almost started writing custom script to handle extra keys when selecting UI button.. but then realized that you can duplicate Input Manager keys, and sure enough […]

Briefly tested https://nuitrack.com/ in unity, and had this error when trying to run examples: DllNotFoundException: libnuitrack nuitrack.NativeNuitrack.Init (System.String config) nuitrack.Nuitrack.Init (System.String config, NuitrackMode mode) NuitrackManager.NuitrackInit () (at Assets/NuitrackSDK/Nuitrack/NuitrackManager.cs:218) NuitrackManager.Awake () (at Assets/NuitrackSDK/Nuitrack/NuitrackManager.cs:117) There is a thread about it in nuitrack forums, https://community.nuitrack.com/t/dllnotfoundexception-libnuitrack/562/23 and the solution […]

Converted this old animated sprite sheet script into shader, its useful for animating sprites from sprite sheet. (when Animator is too heavy for simple sprite animation) Could be extended to have billboard option. Shader source: *Updated: 30/11/18 to fix index wrapping and UV direction https://github.com/UnityCommunity/UnityLibrary/blob/master/Assets/Shaders/2D/Sprites/FlipBook.shader […]

Had problems finding some Debug.LogError messages in the android logcat output, so googled around and sure enough you can enable output colors easily! Just add -v color parameter: adb logcat -s Unity ActivityManager PackageManager dalvikvm DEBUG -v color Note: Default windows Command Prompt doesn’t support […]

Saw this tip at #UniteKL18, fast way to get nearby objects using CullingGroup! (main image with 5000 gameobjects, searching objects within 3m radius) example source code: https://github.com/UnityCommunity/UnityLibrary/blob/master/Assets/Scripts/Docs/UnityEngine/CullingGroupExample.cs my example project: https://github.com/unitycoder/GetNearestObjectsWithCullingGroup Some notes on that: – You need to have MainCamera in the scene (as […]

Quick test for color matching using shader, by converting colors into HSV and comparing target color with h-s-v threshold values. See Shader source at the bottom. (main image: Changing target color, shows inverted color for the texture in that matching hue position) Shader has different […]

I couldn’t find a simple free tool for searching text in files.. so had to make one : / Seems to work well enough already, main just using it for searching unity builtin shader sources 🙂 Still few features to be added.. Sources & Download […]

Quick test for simple convolution filter with unity Texture2D (using c# script, not shader) Source project: https://github.com/unitycoder/ConvolutionFilter
