Shaders that react to objects. How is this created?

Question

Game development

Understanding shaders is very difficult, everything that is on the Internet is just the basics. Could you tell me where to find some information or video (preferably in Russian, preferably) that will show me how this happens.
I'm talking about shaders that interact with different objects, whether it's a bank, something like this ( https://www.assetstore.unity3d.com/en/#!/content/24707) or something like this ( https://www. assetstore.unity3d.com/en/#!/content/24707) , or I won’t show an example, but shields are energy shields, when it hits some place, a wave occurs that diverges through the shader. I hope I explained what I need clearly.

Answer 1

Well, firstly - since you have links to the asset store - buy / download those shaders and disassemble them.
Secondly. I could be wrong here, but still. The shader itself does not interact with objects in any way. There is simply an opportunity to transfer some data from the code to the shader in runtime. Here, for example, at the moment of a hit, the coordinates of the collision are transferred to the shader, and it already draws waves.
