displace each vertex of an object with different amounts using shader?
Hi I'm very new to creating shaders
I have currently an outline shader that extrudes by a specific amount
v.vertex.xyz += v.normal.xyz * _ExtrudeAmount *0.01;
Is it possible to make the _ExtrudeAmount value random between 0 and 1 so that the extruded amount of each vertex is different making the outline look like waves?

Making random in shader is quite computational heavy, but you can have some kind of random : https://answers.unity.com/questions/399751/randomity-in-cg-shaders-beginner.html
If you want wavy lines, you could use for exemple:
v.vertex.xyz += v.normal.xyz * _ExtrudeAmount *0.01 * sin( v.vertex.y * 5 );
This should make vertical waves.
