FPS-Camera with WSAD Keys

[Innocence]

Hello together,

I would like to set up a FPS camera with "WSAD" input, but I do not point really like it functioned.

I hope someone can help me!?

You can change the code in CCameraFPSSceneNode.cpp to use wasd instead of the arrows.

Another way would be to create a Keymap, and pass this in when you addCameraSceneNodeFPS.

Code: Select all

//! Key map added to allow multiple keys for actions such as
//! movement. ie Arrow keys & W,S,A,D.
   SKeyMap keyMap[8];
    keyMap[0].Action = EKA_MOVE_FORWARD;
    keyMap[0].KeyCode = KEY_UP;
    keyMap[1].Action = EKA_MOVE_FORWARD;
    keyMap[1].KeyCode = KEY_KEY_W;
                   
    keyMap[2].Action = EKA_MOVE_BACKWARD;
    keyMap[2].KeyCode = KEY_DOWN;
    keyMap[3].Action = EKA_MOVE_BACKWARD;
    keyMap[3].KeyCode = KEY_KEY_S;
                   
    keyMap[4].Action = EKA_STRAFE_LEFT;
    keyMap[4].KeyCode = KEY_LEFT;
    keyMap[5].Action = EKA_STRAFE_LEFT;
    keyMap[5].KeyCode = KEY_KEY_A;
                   
    keyMap[6].Action = EKA_STRAFE_RIGHT;
    keyMap[6].KeyCode = KEY_RIGHT;
    keyMap[7].Action = EKA_STRAFE_RIGHT;
    keyMap[7].KeyCode = KEY_KEY_D;

   m_pCamera = pManager->getSceneManager()->addCameraSceneNodeFPS(0, 50, 200, -1, keyMap, 8);

Code: Select all

//wasd navigation
	SKeyMap keyMap[8];

	keyMap[1].Action = EKA_MOVE_FORWARD;
	keyMap[1].KeyCode = KEY_KEY_W;

	keyMap[3].Action = EKA_MOVE_BACKWARD;
	keyMap[3].KeyCode = KEY_KEY_S;

	keyMap[5].Action = EKA_STRAFE_LEFT;
	keyMap[5].KeyCode = KEY_KEY_A;

	keyMap[7].Action = EKA_STRAFE_RIGHT;
	keyMap[7].KeyCode = KEY_KEY_D;

and add the keymap to the camera as well:

Code: Select all

//fps cam
	scene::ICameraSceneNode* camera = 0; 
	camera = smgr->addCameraSceneNodeFPS(0,80.0f,300.0f,-1, keyMap, 8);

edited: just noticed it's the same as area's but without the arrow keys!!

It works great! Thank you very much!

sorry about the question:

which value controls the speed of the movement?
or how can i manage the speed of that?

[luckymutt]

from the API:

Code: Select all

ICameraSceneNode* irr::scene::ISceneManager::addCameraSceneNodeFPS 	( 	                 
      parent = 0, 
		f32 	rotateSpeed = 100.0f, 
		f32 	moveSpeed = 500.0f, 
		s32 	id = -1, 
		SKeyMap * 	keyMapArray = 0, 
		s32 	keyMapSize = 0, 
		bool 	noVerticalMovement = false
	) 	

The values shown here are the default values.

thank you
