NewtonWorldGetNextBody give only nil...

[TreantBG]

Code: Select all

Body := NewtonWorldGetFirstBody(NewtonWorld);
  while Body <> nil do begin
    ExplosionCallBack(Body,@Explosion);
    Body := NewtonWorldGetNextBody(NewtonWorld, Body);
  end;

That is my code for looping trough all the world body's.
But ExplosionCallBack is called just oce.

And the interesting thing is when i did the experiment:

Code: Select all

Body := NewtonWorldGetFirstBody(NewtonWorld);
    ExplosionCallBack(Body,@Explosion);
    Body := NewtonWorldGetNextBody(NewtonWorld, NewtonWorldGetFirstBody(NewtonWorld));
ExplosionCallBack(Body,@Explosion);
Body :=  NewtonWorldGetNextBody(NewtonWorld,NewtonWorldGetNextBody(NewtonWorld, NewtonWorldGetFirstBody(NewtonWorld)));
ExplosionCallBack(Body,@Explosion);
  end;

then it worked with no problems...

How can i use NewtonWorldForEachBodyInAABBDo?
What are the second and third parameters?

Code: Select all

 const dFloat* p0 - Start AABB point
const dFloat* p1 - End AABB point

[Stucuk]

They are 3 floats.

Code: Select all

type
TVec3f = Record
 X,Y,Z : Float;
end;

... i know but that want what i asked...

I Ask WHAT the represent?
The body bounds (Left,Right);
The body position (X,Y,Z)

Ok listen now... i want to get the body's in radius X around point P how to do it with NewtonWorldForEachBodyInAABBDo??

p0 and p1 is the min/max bounds of the AABB.

For example p0 = -100,-100,-100 & p1 = 100,100,100 which is an AABB 200 units in each axis centered around point 0, 0, 0.

Obviously this function will only return the bodies within an Axis Aligned Bounding Box but if you want to check bodies within a specific radius instead simply make the AABB bounds as large as the bounding sphere you want to check and measure the distance to each body that NewtonWorldForEachBodyInAABBDo return.
