How to get flat lighting in Unity and C#?

Question

I'm pretty new to lighting in Unity, but I've asked on Unity forums and pored over questions like http://answers.unity3d.com/questions/955346/flat-lighting-for-3d-game-with-orthographic-camera.html but I can't achieve the same lighting as Crossy Road - flat, vibrant colors but with shadows .

From tutorials I know I need a directional light, but all my directional lights wash out my colors and don't evenly distribute. Right now I have an ambient light, only problem is no shadows:

What can I do here? Are there specific settings to try?

Answer 1

The shading is "flat" because the objects are:

• composed of faces that are generally at right angles to one another
• no curved surfaces
• shader should treat light sources as being at infinity
• shader should not vary colour as a function of a point on the face and light angle
• max diffuse shading
• zero specular shading
