/* Explanation of values added to struct entity_s
|
|
*
|
|
* formula:
|
|
* takes a value 0-3 (default 0)
|
|
* 0 - Standard lighting formula like original light
|
|
* 1 - light fades as 1/x
|
|
* 2 - light fades as 1/(x^2)
|
|
* 3 - Light stays same brightness reguardless of distance
|
|
*
|
|
* atten:
|
|
* Takes a float as a value (default 1.0).
|
|
* This reflects how fast a light fades with distance.
|
|
* For example a value of 2 will fade twice as fast, and a value of 0.5
|
|
* will fade half as fast. (Just like arghlite)
|
|
*
|
|
* mangle:
|
|
* If the entity is a light, then point the spotlight in this direction.
|
|
* If it is the worldspawn, then this is the sunlight mangle
|
|
*
|
|
* lightcolor:
|
|
* Stores the RGB values to determine the light color
