Moved camera...

[Texel]

How to make in order to the camera moved forward to the left button of the mouse at the press?

[Oz]

smgr->addCameraSceneNodeMaya(0);

Allows the camera to be controlled using the mouse. Both mousebuttons + left-right movements are in/out or backward/forward.

But I think what your asking is how to get the IN vector of the camera then add it to its position. Im not sure how to do that yet, ill take a look ...

EDIT: Golly, this was easy with Genesis3D!

geXForm3d_GetIn(&cameramatrix, &in);
geVec3d_AddScaled(&cameratranslation, &in, movespeed);

/* this is essentially a 'standard' 4x4 transform matrix,
with the bottom row always 0,0,0,1

| AX, AY, AZ, Translation.X |
| BX, BY, BZ, Translation.Y |
| CX, CY, CZ, Translation.Z |
| 0, 0, 0, 1 |
*/

The in vector is (Genesis3D)
In.X = -Matrix.AZ;
In.Y = -Matrix.BZ;
In.Z = -Matrix.CZ;

Since my head is about to explode ill also ask a question which could be brain-dead simple. (so in the wrong forum, but hey)

In IrrLicht, how do you get the In vector from a matrix?

[Texel]

It is an old piece of a code

Code: Select all

core::vector3df  vec;
vec = smgr->getActiveCamera()->getPosition();
vec += core::vector3df(5,0,5);
smgr->getActiveCamera()->setPosition(vec);

One more variant

Code: Select all

// get line of camera

core::vector3df start = global_camera->getPosition();
core::vector3df end = (global_camera->getTarget() - start);
end.normalize();
end = start + (end * global_camera->getFarValue());

core::line3d<f32> line(start, end);

And then I do not know as to do(make)...
If there was getRotation() in degrees.

LOL took me a while to figure out the In vector. Im rusty

Code: Select all

	matrix4 cameramatrix = camera->getRelativeTransformation();

		/*
		0  1  2  3
		4  5  6  7
		8  9  10 11
		12 13 14 15
		*/

	vector3df	in(	cameramatrix.M[8],
					cameramatrix.M[9],
					cameramatrix.M[10]);
	vector3df pos = camera->getPosition();

	pos += in;
	camera->setPosition(pos);

Put that in your event reciever for your left-mouse button.

Hope this helps!

EDIT: BTW I just answered my own question too, it was fun!

I hope someone will explain what I meant to you (in Russian)

If I didnt help, ask again.

The thank!!!
This code works! =)))))

basically the camera's Z axis is its front
