Collisions with energy shield

Hello, I need advice on how to do one thing. I doing Stargate game, in which I want to add energy shields for ships. I need a shader or another principle, which makes me the effect of a collision shield like this:

This is in Asset “Force Field” but i cant buy this asset. How can I do this? These instructions do not work to me:http://answers.unity3d.com/questions/605306/shader-change-alpha-around-collision.htmlhttp://forum.unity3d.com/threads/energy-shield-hit-effect.220018/

Already using Unity 5

What do you mean by “do not work for me” ? Is the shader not compiling properly? does the script don’t work? (the 1st link you post have a unityscript script, not a c# one, you will need to convert it if you’re using C#)

There were no errors. Scripts and shader works. But at the collision point showed nothing.
So what i did you more? I can not write shaders
