Hey Folks,

I'm trying to adapt tutorial #14 for MFC but am only getting a blank black window. I know the Irrlicht device is drawing something because it turns black. But there are no shapes. I basically made a new MFC project and added some of the code from tutorial 14 to the CMainFrame class in a ...

Wait a minute! I'm getting a psychic transmission from the mystics! They tell me... this 'snake game'... is for a ... school project!

(Look about ten posts down from yours in the forum, homee).

FYI: I create only one instance of an IrrlichtDevice and extern it (global) for other classes to use. Totally lame use of globals, I'm sure. But it's easy and I really haven't had any problems with it yet.

What do you mean by "goes in loops"? Is it rotating too fast? Is it only rotating in one direction? Does it not stop spinning?

That book looks pretty interesting. Amazon reviews are pretty high. How about this one though? http://www.amazon.com/Game-Programming- ... im_b_img_5 Has anyone ready it or heard any positive/negative reviews?

That sounds like about five different questions in one. It sounds like what you want to know is how to make something your character has bought appear on the screen. Is this what you really want to know? If so then here is a quick (and very simplified ) series of steps:

1) make the mesh in a 3D ...

I think hash<int, list<obj_reference>> would make it a little quicker to remove items from a bucket.

Also, in terms of a spatial grid, would an R-Tree be too costly to maintain? (http://en.wikipedia.org/wiki/R-tree)

Ah, I see. Sounds like I'm heading for a single axis search algorithm. Thanks guys!

In fact, it *is* a 3d space-based RTS and I am considering a unit count on par with Supreme Commander. So, ~5000 units max (all teams) would be about right. I'm thinking that the unit positions will tend to be very "clumpy" - that is many units will tend to be clustered around resources or bases ...

Hi folks, I am making an RTS and need a quick way to allow units to "see each other" by search through all scene nodes and determining who is within a certain proximity - like radar. I was thinking something along the lines of the octtree as defined by wikipedia (http://en.wikipedia.org/wiki/Octtree ...

Forget it and please don't vote me off the island for being stupid. I'm going to continue using getSceneNodeFromScreenCoordinatesBB() for when the meshes are close to the camera then I'll use a GUI element like a button or something similar for when the mesh is far from the camera.

sfncook

Exactly, keless, this an RTS (perhaps I should have mentioned that in the first post, duh). So there will be potentially many hundred if not a couple thousand game pieces. I assume that getSceneNodeFromScreenCoordinatesBB does this in a more efficient manner than just checking every mesh with a for ...

Hi folks,

I have a scene in which I may zoom far out and wish to still be able to easily determine which game piece the mouse is currently over. Currently I'm using this method:

irr::scene::ISceneNode* selectedSceneNode = smgr->getSceneCollisionManager()->getSceneNodeFromScreenCoordinatesBB(irr ...

Hehe, thanks for the help thus far, folks. The irrlicht community is truly the best (most polite and helpful) I've ever encountered. I think i was a little confused by the threading situation. I had a thread for RakNet functionality and have now moved that functionality into the main thread. I ...

Poorly. hehe. Here's the code:

Code: Select all

bool Lock(void)
	{
		if(!lock) {
			lock=true;
			return true;
		}
		else {
			return false;
		}
	};

Irrlicht Drawing a Blank MFC Window

Does Irrlicht provide spatial indexing (searching) utility?

I need a better way to mouse pick.
