Hello,

I did never worked with irrNet (first time I heard from it), so I can be wrong.

But maybe you could try to remove the netManager->update(100) in this code.

if(netManager->getConnectionStatus() != net::EICS_FAILED)
{
net::SOutPacket outpacket;
outpacket << str.c_str();
outpacket ...

I think he means setTarget.

It's easy:

Code: Select all

core::vector3df Point1 = core::vector3df(X1,Y1,Z1);
core::vector3df Point2 = core::vector3df(X2,Y2,Z2);
core::vector3df vect = Point2-Point1;
node->setRotation(vect.getHorizontalAngle());

(!) only 3 numbers can define a rotation, so Y-axis -> always up

I do think it's something with the normals...

You could flip the normals of a face individual.

(Edit mode -> select the face to flip the normal -> press W-key -> flip normals)

In blender (edit mode) you can show the normals -> Mesh Tools More -> show Normals.

Wow, nice

I tryed that in 2D, but I got problems. So I stopped trying

@ PI: The point you are searching is not the closest point, it's the intersection of PM (P=given ; M=middle) with the ellips...
That's because you scale around the center point.

The other solution with the tangent...

You could eventualy calculate some points of the ellips, and for ...

Hello,

I think I know an easy way to get the closest point!!!

First you search the two focus-points, you find them by:
f32 c=sqrt(kwa(a)-kwa(b));
core::position2di focus1 = core::position2di((s32)(-c),0);
core::position2di focus2 = core::position2di((s32)(c),0);
(If (0,0) is the middle point)
(a ...

Maybe the program is just exiting because it can not find a resource, or it's not able to initialize the device.

Code: Select all

if (!device)
	return;

if you have:

P = given point (?,?,?)
Q = point you search (x,y,z)

Then vector PQ stands _|_ upon the tangent at Q.

Using some math you should be able to solve it.

Hello,

When you want to set the camera rotation, you first have to set bindTargetAndRotation to true.
(I think it's a bug in irrlicht, if you don't set it to true, the target is not updated, and in the draw code it uses the target, so setting the rotation does nothing...)

A better name for ...

See the irrlicht source code:

Code: Select all

		// if there is an icon, load it
		wcex.hIcon = (HICON)LoadImage(hInstance, "irrlicht.ico", IMAGE_ICON, 0,0, LR_LOADFROMFILE);

source: CIrrDeviceWin32.cpp line 327-328
