Hello guys,
 

I need a shader that would follow the cursor. Where to find ? or how to create?

What kind of effect are you looking for?

Honestly I do not know where you can get a shader like that, maybe I have other alternatives but I can not think of anything.

@AncienT

what alternatives do you have?

I was gonna say you could try dxDrawPrimitive for this, but it's no good if you want curved edges, so you probably want a mask shader, perhaps using dxDrawPrimitive to generate the part which follows the cursor. You'll need to use either trianglestrip or trianglefan.

Just get the cursor position with getCursorPosition, and if it's inside the image, change the image color to pink and you will have that effect.

I just have no idea how to implement it in my head. the arrow repeats the cursor

A simple mask shader should help you. Just create an arrow texture and use it along with the mask shader. An example of this shader you can find at Shader_examples
