Object on illuminated by ligth component
Hello everyone, I'm getting a problem whit scripting. I dont have any idea how to detect when an object has been illuminated by a specific ligth component.
I search in google but can't find a working awnser.
I hope than i can find the rigth awnser here. Have nice day. PS: Sorry, I dont speak english as well.
Best Answer
depends on the light type.
spot light
check if angle between light forward direction and light-to-object direction is less then half spot light angle check if distance to object is less then max distance of light * check if raycast to object hits object and not other geometry that can hide objectpoint light
* same as above but skip first item with angledirection light
just raycast check from (object-position - light-direction K) to object-position, where K is big enough to be outside from whole scene, to hit any geometry that can cover object
Thanks, it is really helpful but How i check "check if raycast to object hits object and not other geometry that can hide object"?
