Unity Ripple or Shock Wave Effect

by Devon O.· September 24, 2017· in Shaders, Unity3D· 20 comments tags: shaders
So, here’s another quick Unity3D tip. Incidentally, speaking of Unity, for anyone wondering what happened to the multi part endless runner posts I started, I decided to quit that since the folks at Unity released their own endless runner game which is much more fully featured. You can check it out here – it’s a great source. Anyway, here’s a little image effect shader that can create a nice ripple or shockwave or etc type of effect: [crayon-6046d26dcbb7b036297744/] Apply that shader to a material then add that material to this post processor script (which should be added as a component of the Main Camera). [crayon-6046d26dcbb8c541259500/] You can play around with the public properties of the material and the RipplePostProcessor component in the inspector, but here’s an example of what it can do – just click around the scene (again, using the fantastic Blacksmith’s Forge package). Hope it may help out.

Spritesheet Scene Transitions in Unity3D

by Devon O.· September 16, 2017· in Shaders, Unity3D· 0 comments tags: shaders
Over the past couple weeks I’ve been working on  a number of transition effects for use with the Starling Framework. One of my favorites involved using a Starling MovieClip of a greyscale sprite sheet animation to hide or reveal a DisplayObject instance. For example, you could take a black and white frame sequence of something burning or a spreading ink splotch and use it to transition an image in or out. After completing the Starling work, I got to wondering if I could do the same thing in Unity3D with the same spritesheet and texture atlas assets. Of course with a little finagling it turns out I could so I thought I’d share this little tip for anyone looking to do something similar. What It Is Before going any further it would probably help to present a visual idea of what the heck I’m talking about. Click here for a WebGL example of the type of effect this technique can create. Just to make the example scene more interesting, I used a fantastic Blacksmith’s Forge interior from 3DForge available for free on the Unity Asset Store. So what’s happening? Essentially, there is a spritesheet animation of a spreading blob of […]
