Displaying Irrlicht in a c# picture box

Has anyone successfully displayed irrilicht within a c# picture box control? How to do it?

I get an error "Color is an ambigous reference" with the following code that is inserted in the main loop:

while(device.Run())
{
if (device.WindowActive)
{
device.VideoDriver.BeginScene(true, true, new Color(0,100,100,100));
device.SceneManager.DrawAll();
// draw the logo
device.VideoDriver.Draw2DImage(
texLogo, new Position2D(10,10),
new Rect(0,0,88,31),
new Rect(new Position2D(0,0),device.VideoDriver.ScreenSize),
new Color(0xffffff), false);
device.VideoDriver.EndScene();
//display frames per second value
if (fps != device.VideoDriver.FPS)
{
fps = device.VideoDriver.FPS;
device.WindowCaption = "Scalper 2005 ["+ device.VideoDriver.Name + "] fps:" + fps;
}
}

You have to write the following when you create your device

if your picture box is named picturebox1

Code: Select all

IrrlichtDevice device = new IrrlichtDevice(DriverType.DIRECTX9, new Dimension2D(picturebox1.Width, picturebox1.Height), 16, false, false, false, true, picturebox1.Handle

Sorry, was not logged in.

That's the device creation you have to use at start of your Init function.

Use code tags from now on, ok?

"Color is an ambigous reference" is because there is a Color class/struct in Irrlicht.Video AND System.Drawing. You need to qualify the reference with the full namespace. ie:

Code: Select all

device.VideoDriver.BeginScene(true, true, new Irrlicht.Video.Color(0,100,100,100));

Code: Select all

		[STAThread]
		static void Main() 
		{
			Application.Run(new Form1());
			IrrlichtDevice device = new IrrlichtDevice(DriverType.DIRECTX9, new Dimension2D(pictureBox1.Width, pictureBox1.Height), 16, false, false, false, true, pictureBox1.Handle);
			while(device.Run())
			{
				device.VideoDriver.BeginScene(true,true,Irrlicht.Video.Color(128,128,0,255));
				device.SceneManager.DrawAll();
				device.VideoDriver.EndScene();
			}
		}
	}
}

You are trying to access pictureBox1 control (that is non-static) from a static function (main)

create a Form1 method like this

Code: Select all

public void Init()
{
			IrrlichtDevice device = new IrrlichtDevice(DriverType.DIRECTX9, new Dimension2D(pictureBox1.Width, pictureBox1.Height), 16, false, false, false, true, pictureBox1.Handle);
			while(device.Run())
			{
				device.VideoDriver.BeginScene(true,true,Irrlicht.Video.Color(128,128,0,255));
				device.SceneManager.DrawAll();
				device.VideoDriver.EndScene();
			}

}

and then call it from Form1 load using this code

Code: Select all

irrThread = new System.Threading.Thread(new System.Threading.ThreadStart(Init)); 
irrThread.Start();

Using .NET 1.1 w/ VS.NET 2003

I am using my own loop, and each iteration I call the following:

Code: Select all

device.Timer.Tick();
device.VideoDriver.BeginScene(true,true, new Irrlicht.Video.Color(128,128,128,128)); 
device.SceneManager.DrawAll(); 
device.VideoDriver.EndScene();

When running this in a picturebox, the cursor is stuck to the center of the picturebox, I noticed that keyboard events aren't being processed any longer, along with that setting the cursor to invisible does not work (this is irrelevant for me, but it still doesn't work nonetheless)

I was wondering if there was a way to release the cursor from the control or Irrlicht so that the user can use the cursor to navigate controls in the program, switch windows without having to alt+tab... all the things you can do with a mouse thats not stuck in the middle of the window.

I've looked through the source code, found the mouse message processing, checked icursorcontrol etc.. but I can't seem to find anything that would release the mouse cursor from the clutches of irrlicht. I'd rather not have to make my own irrlicht fork and have to update the message processing stuff with each new release.

Unless I am completely missing something (which is more probable than I'd like to think) I guess I'm asking for a feature request of the ability to turn off irrlicht's input processing so that I can process the mouse/keyboard events on my own.

Thanks
Gabriel

Have you tried slipping this into your loop?

System.Windows.Forms.Application.DoEvents();

Gabriel · Post by **Gabriel** » Thu Dec 01, 2005 4:51 am

Yes, that is there.

Guest · Post by **Guest** » Fri Dec 02, 2005 2:09 pm

now try this

ICameraSceneNode cam =
device.SceneManager.AddCameraSceneNode(null, new Vector3D(20, 0, -50), new Vector3D(0, 0, 0), -1);

the fps cam locks the cursor (imo)

Gabriel · Post by **Gabriel** » Fri Dec 02, 2005 8:34 pm

Sweet!

Odd that the camera has anything to do with input.
