Any idea?

ok... so this code works...
NxOgre::NxString test;

for(int counter =0;counter<4;++counter)
{
test="rope" + counter;
m_Body = m_Scene->createBody(test +"; RopeCap.mesh",new CapsuleShape(2,5),NxOgre::Pose(Vector3(-50,200-counter*10,200)),"mass: 10");

if(counter>=1)
{
m_RevoluteJoint = m_Scene->createRevoluteJoint(m_Scene->getActor("rope"+(counter-1)),m_Scene->getActor("rope"+counter),Vector3(1,1,1),Vector3(-50,195-(counter-1)*10,200));
}

}


but if i set for loop to for(int counter =0;counter<5;++counter)
(only difference being <4 to <5)
suddenly i get this exception when running the program... any ideas???

I think you don't have the + operator in NxString class.
May be it's for this reason.

yeah but it would then fail all the time surely and not when i go above 4 iterations... ?

If the operator + doesn't exist then it behaviour may be unpredictable but i'm not sure.
Print the string every loop to see if it's correct.

It cant find file called "; RopeCap.mesh" so the error is with strings.
Try to use Ogre::String!

NxOgre has built in protection for Actors with duplicate names, it will call it Test, Test1, Test2, Test3 and so on. So you don't even need to use that integer with the string.

So it goes:

m_Body = m_Scene->createBody("test;RopeCap.mesh", ... );

hmm.. you sure thats exact syntax.. it stops working completely if i do

m_Scene->getActor("rope"),m_Scene->getActor("rope"+counter)

m_Scene->getActor("rope"+counter)

Is causing the problem. Use m_Scene->getActor("rope" + Ogre::StringConverter::toString(counter));

Cool thanks that converter thing worked perfectly /thumbs up
