Adding point light support to shader?

Unity Engine
1

Hey, currently got this toon shader, but it only uses the directional light right now, which isnt great. I’d like to add point light support too. How could I do this?

You can use #if defined(POINT), #if defined(SPOT) and #if defined(DIRECTIONAL) to check the type of the current light.

For point lights, you then get the light direction by doing something like lightDir = normalize(_WorldSpaceLightPos0.xyz - worldPos);

Lastly, the UNITY_LIGHT_ATTENUATION macro can be used to calculate the point light’s distance attenuation.

Beyond that it’s the same as directional lights I think?
