Hi all,

I make 9 indipendent objects as an airplane parts.
Some of these objects are DB primitive objects and some are X objects.

obj 9000 ---> left wing
obj 9001 ---> right wing
obj 9002 ---> aircraft main body
obj 9003 ---> tail cone
etc etc

Ok when I finished to build my objects so I started to position them in right coordinates,right angles and right scale size to obtain a 3D airplane.
Ok, so If I start my program I can see an airplane made by my 9 indipendent objects.

Nothing in this plane is linked or limbed, is a 3d airplane made by 9 objects.

Now the troubles..
I try to make all my objects limbs linked to the "aircraft main body" object... (see attached pic!)
Here the steps :

1) I set my "aircraft main body" object (numb 9002) as MAIN AIRCRAFT OBJECT

+ Code Snippet

 Offset Limb 9002,0,0,0,0 
 Fix Object Pivot 9002

2) I make a mesh for each objects (except "aircraft main body" obj)

+ Code Snippet

 MAKE MESH FROM OBJECT 1,9000 rem LEFT WINDG MESH
 DELETE OBJECT 9000

MAKE MESH FROM OBJECT 2,9001 rem RIGHT WINDG MESH
 DELETE OBJECT 9001

MAKE MESH FROM OBJECT 3,9003 rem TAIL CONE MESH
 DELETE OBJECT 9003

etc etc

3) I build my airplane limbs!
All my old and deleted objects has become mesh! (EXCEPT THE "aircraft main body" OBJECT!)

+ Code Snippet

 ADD LIMB 9002 ,1,1 rem    Creo limb 1 con mesh left wing
 ADD LIMB 9002 ,2,2 rem    Creo limb 2 con mesh right wing
 ADD LIMB 9002 ,3,3 rem    Creo limb 3 con mesh tail cone

etc etc

FINISH! I made all my old airplane parts become limbs linked to the "aircraft main body"!
So now I have my object number 9002 as my complete airplane!
BUT you can see the result of that process in the attached pic... some objects had lost their scale size too.. as well as thier coords and angles..

I tried to use a code like that:

+ Code Snippet

 OFFSET LIMB 9002,1,0,0,0
 OFFSET LIMB 9002,2,0,0,0
 OFFSET LIMB 9002,3,0,0,0
...
Fix Object Pivot 9002

but I got nothing...

Where I am in error??

I don't think MAKE MESH takes the model view matrix into account, so the output mesh resembles the constituent parts in their original
unrotated \ unscaled form.

But I've never used MAKE MESH so I could be talking out my #?*

you have to offset each limb and rotate/scale them

mmm I need to offset each limb and rotate/scale them...

So I need to use :

+ Code Snippet

OFFSET LIMB 9002,1,0,0,0
OFFSET LIMB 9002,2,0,0,0
OFFSET LIMB 9002,3,0,0,0

but what I need to put instead 0,0,0 ?? The original xyz position of the airplane parts?
I am in real confusion here..

We have encountered this problem in our own projects and were able to solve the problem of
positioning limbs. If you could post your code we can provide you with an example to solve this.

At this point I get what you can see in the picture I previously attached.

I get all my aircraft parts joined to the "MAIN AIRCRAFT BODY" loosing all correct coordinates, angles and scale size

I avoid to use "Fix Object Pivot" command in this code.. If I using it or not the result is the same..

Could you attach your ".x" objects so I don't have to create new objects.
Yes I saw your pic and I understand what is happening.

Hi there.
As you commented, we have to make mesh from every object you want to add as limb, then when we add them, we have to offset every limb to the real x,y,z position of every object and last delet those objects.

for example, if we want to add 10 limbs to the our object:

+ Code Snippet

for i= 1 to 10
   make mesh from object i,i
   add limb my_object,i,i
   offset limb my_object,i,object position x(i),object position y(i),object position z(i)
   delete object i
next i

We have to make sure how many limbs has the object that we load....so if our object has two limbs, the next to add will be limb three....so in the FOR NEXT, we have to increase a variable .

Cheers.

Why not use a system where you glue objects to limbs. You could then swap out parts easily to simulate upgrades, payload, and damage.

In game you could say an engine is out and replace that section with a ripped up and burnt version. Etc.

It's not all that efficient baking into the object during runtime meshes like missiles and things that detach from the aircraft. I think it's better to "glue" that stuff instead. Taking that approach further and gluing everything makes things every interesting.

If you don't have any intention of doing stuff like that then I'd recommend assembling the plane completely in a model editor. You can still use limbs and you would save yourself some trouble.

@Stab in the Dark software:
Hi dude and thxs for your help! here attached the X objects!

@chafari:
Now I am using a PC without DBPro but your code seems pretty good the reach my goal! Later I will try for sure!

@Mage
Interesting! and I think about some of the features you talking about! Some tests soon about!

PS: THANK YOU GUYS!
