Looking for some guidance on my game engine task manager.

Hi community,

I'm looking for some solutions for threading my game engine.

Currently this is how I have my system setup.

I have a main loop, like this

loop()

{

update();

renderAll();

}

In update, it essentialy goes through the node list and calls update for every node.

for (NodeIter it = NodeList.begin();

it != NodeList.end();

++it)

{

(*it)->Update(fTick); // This handles AI and other updates

}

In renderAll(), it basically checks that objects are in view and renders them.

Now the reason I want to thread this game engine is because I have recently started implementing a heavy AI system and it's starting to slow down my game a bit.

Physics is handled by Havok and already multithreaded.

I can have thousands of objects on the screen, but when I start to do intensive AI it slows down a little.

Anyway, I have looked through Smoke, Nulstein andTaskingGameEngineAnimation material. They all have a different way of doing the threading.

Anyone have any recomondations on how to use TBB for threading.

Sorry this post looks a little messy, I'm in a rush to post it and I'll be back later to update it.

Thanks all!

I know this is a pretty old thread, but...
For your mode updating, try something like this:

[cpp]#include <...> // Other includes
#include 
using namespace ... // Other namespaces
using namespace tbb;

// ...
 update()
{
   parallel_for(Nodelist.begin(), NodeList.end(), [=](ModeIter it) {(*it)->Update(fTick); });
}

//...[/cpp]
