How do you manually control a camera?

[muller]

Im previously a java programer and am new to c++.

So far I've been able to make a regulkar camera like this:

Code: Select all

scene::ICameraSceneNode* camera = scenemgr->addCameraSceneNode(node, core::vector3df(0, 200, 100), core::vector3df(0, 200, 100), 1);

The second vector3df is for a target to look at. But i don't want that. I want to manually set the rotation and position of a camera. I've tried to use setUpVector(core::vector3df) to override the the look at but it doesn't work.

I see that ICameraSceneNode's constructor takes position and a rotation, but i always get errors when constructing it:

Code: Select all

scene::ICameraSceneNode* camera = new scene::ICameraSceneNode(node, smgr, 1, core::vector3df(-200,200,-200), core::vector3df(0, 100, 0), core::vector3df(1.0f, 1.0f, 1.0f) );

And yes i am trying to make 'node' a parent of the camera.

Could someone please give an example of how to make a camera that is manually controlled.

Thank you for your time.

ICameraSceneNode is just an interface. You can't new interfaces (true in Java too. )

ICameraSceneNode is subclass of ISceneNode and ISceneNode has functions to change position and rotation. See API docs.

So how to move camera manually?
I redefine EventReceiver to be able to use GUI and game, I haven't seen any tut on this (WHY? Don't games have GUI?). So I need to move camera from there manually. Can you tell me how to do it?
More certainly, how to:
1) move forward;
2) move backward;
3) strafe left;
4) strafe right.
I guess, I should change ViewMatrix, but how? What formulas should I apply?

Thanks.

I think there might be a code like this in the demo in SDK.In demo you can move camera with W,S,A,D try to look at demo's code.

scenemgr->addCameraSceneNodeFPS();

W - forwards, S - backwards, A-D - left - right.

scenemgr->addCameraSceneNodeFPS();

W - forwards, S - backwards, A-D - left - right.

Isn't default keymapping with arrows keys for movement and mouse for target ?

There is an example on documentation about how to make a special key mapping :

ok, i've looked into Demo, and this is what i wanted:

Code: Select all

 if (ev.EventType == EET_KEY_INPUT_EVENT) {
                switch (ev.KeyInput.Key) {
                        case KEY_KEY_W:
                        case KEY_KEY_S:
                        case KEY_KEY_D:
                        case KEY_KEY_A:
                                dev->getSceneManager ()->getActiveCamera ()->OnEvent (ev);
                                break;
                } // switch
        }

scene::ICameraSceneNode* camera = scenemgr->addCameraSceneNode(node, core::vector3df(0, 200, 100), core::vector3df(0, 200, 100), 1);

Hi
if i m not wrong ...

using "node" as firs parametwer you set the camera as parent of the "node"

so moving the node (rotating ecc.. ) the camera will rotate ecc.. with it
