To Optimize cloth

[arvin.mittal]

Hi,
I have drawn the cloth ( soft body) and made it fall on ball. It falls very slowly due to calculations which make it slow, how can I optimize my code and make the cloth fall fast.

Hi!

How large is your cloth? Do you use selfcollision?

Hey thanks for your reply.....but i have solved that......I was doing it wrong earlier
Help me in optimizing this...

foreach (RigidBody body in world.RigidBodies)
{
if(body.Position.y< -10)
{
world.removebody(body);///////it crashes at this point.....i want to remove the body which is not in my view....plz tell
}
if (body.Shape is SphereShape)
{
if ((string)body.Tag == "mySphere" )
{
//SphereShape shape = body.Shape as SphereShape;
GLES1.glColor4f(0.0f, 1.0f, 1.0f, 1.0f);
dsDrawSphere(body.Position, body.Orientation, radius);
}
}
}

What's the error message you get?

error comes when sphere body falls below -10units.(ie. body.position.Y < -10)

foreach (RigidBody body in world.RigidBodies)

//invalid Operation exceptionwas handled
Collection was modified; enumeration operation may not execute.

please reply..
Thanks

That error comes from the foreach loop.
you often cant write in the variable you are iterating throught, only reading is allowed.
If you use a for or while loop it should work.
