Getting bodies joined together

[PJani]

I have pointer to one body how can i get full tree of joined bodies. So i can set position of full object not only of one body.

Example what i mean. If i want to move vehicle then i need to know which bodies are joined to that body chassy or else i will get exploded vehicle when setting position.

NewtonJointGetBody0
NewtonJointGetBody1

Sometimes it really is that simple

These two function are helpful when i have joint pointer. but i dont!! I have only base body pointer!.

you will need to use a tree walk using the functions GetFirstJoint() GetNextJoint() something like this

Code: Select all

void GetJointForest (newtonBody* root, containet bodyList)
{
      MyUserData = NewtwonGetUserData(body)
      if (! MyUserData->FourestFlag()) {
            bopdyList.Push (body)
   
           // set a f;ag in teh user data of you body
            MyUserData->SetFlag (1);

          for (joint =  NetwopnGetFirstJoint(body); joint;  joint = NetwonGetNextJoint (body, joint)) 
           {
                 if (joint->GetBody0() != body)  {
                      GetJointForest (joint->GetBody0() , containet bodyList)
                 } else {
                     GetJointForest (joint->GetBody1() , containet bodyList)
                }
           }
     }
}

I hope you get the idea
