[SOLVED] [QUESTION] [DBC] Different skies in the same map

[Kiun]

I'm looking for someone who can help me to figure out how Light.dbc works. Specifically columns 3-5 which are float values of position.

I want different entries in Light.dbc for the same map but with different coordinates so the sky/light/fog would change depending of the zone.
E.g. Outland map (entry 530 in Map.dbc) have multiple entries in Light.dbc to use different skies in its different zones (Hellfire Peninsula, Shadowmoon Valley...)

The problem is that I can't figure out how coordinates work, those columns 3-5 maybe are a bounding box? Are the coordinates the same as in ingame? :?

At Light.dbc wiki (http://www.wowdev.wiki/index.php?title=Light.dbc) I can see a footer: 'LightRec::ConvertDBToGameCoords()'
but I don't understand what means '36.0f;'.  :?

Thanks in advance.

They are the center of the light, where each coordinate is multiplied by 36.

Ok, if they are the center of the light I assume columns 6 and 7 are radius, but still don't understand how the formule works.

pos.x (1) = 17066.666 - pos.x (2) / 36.0f;

pos.x (1) is the DBT coordinate or the ingame coordinate?
pos.x (2) will be which is not the pos.x (1), right?

[schlumpf]

That function is called on the dbc entries, thus

Code: [Select]

pos.x(1) = 17066.666 - pos.x(2) / 36.0f; will convert the db coordinate (2) to the world coordinate (1) by dividing by 36, and subtracting from 17066.666.

Solved, I was doing the function right but the columns 3, 4 and 5 are Y Z X respectively and I was assuming it was X Y Z.

Thanks again schlumpf.
