Ah thanks for trying to help me out!
and also thanks for the tutorial videos! I've seed this videos before and they have helped me a lot
Since it is inconvenient for you to see the videos, I brought an image to explain what I want to achieve.
So the image I've attached is what I want to make with playmaker.
This is an free asset named '2D Dynamic Lights and Shadows' (the link:https://www.assetstore.unity3d.com/kr/#!/content/24083)
and what I want to understand are how to get the points the light hits, color specific areas, and the changes of radians and segments of the light.
Sorry if I'm bothering you. I am just working on this for quite long time and frustrated because I still couldn't find the answer..
If you cannot answer me right now. It's ok!
Thank you for reading all this
