Is any way to make pointer to an object in DGDK C++? For example, pointer to a box or a mesh loaded? I tried to find something like dbPointerToObject* ptrob, but it seems there is not such a thing, or something like that. Could be:
dbPointerToMesh
dbPointerToBox
...
While dbPointerToObject is more friendly for lazy people like me

Nope, object system works the same was as DBPro, being referred to by their index. You could make your own class if you wanted to, though.

Edit: Or not. Didn't know about that, Apex

Give or take a few bugs (though a lot more give than take).

May I make a correction... There is a function that gives you direct access to the object data, it's called dbGetObject. It needs to be uncommented in your DarkSDKBasic3D.h file as it's not actually available by default. You will also need to add the line #include <DBO Format/dbodata.h> to the top of that header file as well, otherwise the compiler will moan because it cannot find sObject*.

But APEXnow, that needs global.h in dbodata.h which doesn't exists. Actually, dbodata.h is not usefull now as it needs other definitions in global.h.

Paul, well, the pointer works but it seems that using pointer-to-object is not yet supported for other APIs. I think I have to leave it right here. DB engine is for avoiding low level annoyances in the first place.

Apex, you should have told that dbGetObject fixing at your ghost object workaround thread, I had problems compiling it.
[EDIT Forget about last comment, my fault.

By the way, in the worst situation, I'll be glad to have a dbObjectSize workaround, maybe there is a door somewhere with this pointer-to-object?

if anyone can find a way to get the size of limb I will be able to finish my dbLimbInScreen() command - as it is my command works... but its totally inaccurate as all i can do is calculate the center position of the limb using dbLimbPosition() and cannot calculate the edges to make a proper bounding box :/

Sephnroth,

you can try:

dbMakeObjectFromLimb

and the get the size of the limb with

dbObjectSize

applied to the new object (at least with 1.1.1)

You could have precalculated limb sizes using dbMakeObjectFromLimb/dbObjectSize for all limbs before any loop, store the values, and it will work faster.

I guess that should work...

it is possiable - but we are talking a LARGE increase in loading time for that. The routine needs to run on the world geometry and the world object is made up of over 400 limbs on a /small/ test map. Quite ungh :/

Maybe then you can pre-calculate the data with an auxiliar program and use the results in the final project. Not at run-time.

That is, 2 separated sources or functions, one for calculating sizes before run-time, and the other for knowing if the limb is on screen (dbLimbInScreen command itself).

it is of course a possibility - maybe the only one. But it is working around a lack of functionality that is quite shocking not to be there :x such a simple thing, lol

I will continue investigating. I've worked extensivly with dbGetObject in the past for various things and never found any limb sizes in there, but maybe theres something i;ve overlooked or something
