A billboard is like a 3d sprite: A 2d element, which always looks to the camera. It is usually used for things like explosions, fire, lensflares and things like that.

Parameters

Parent,:

Parent scene node of the billboard. Can be null. If the parent moves, the billboard will move too.

Returns

The created scene node. This pointer should not be dropped. See TReferenceCounted,.Drop() for more information.

Adds a camera scene node to the scene graph and sets it as active camera.
This camera does not react on user input like for example the one created with AddCameraSceneNodeFPS(). If you want to move or animate it, use animators or the TSceneNode.Position, TCameraSceneNode.Target etc properties. By default, a camera's look at position (set with Target) and its scene node rotation (set with Rotation) are independent. If you want to be able to control the direction that the camera looks by setting Rotation then set TCameraSceneNode.BindTargetAndRotation to true.

Parameters

Parent

Parent scene node of the camera. Can be nil. If the parent moves, the camera will move too.

Returns

The created scene node. This pointer should not be dropped. See TReferenceCounted,.Drop() for more information.

Parameters

Parent

Parent scene node of the camera. Can be nil. If the parent moves, the camera will move too.

Position,:

Position of the space relative to its parent where the camera will be placed.

Target

Position where the camera will look at.

ID

ID of the camera. This id can be used to identify the camera.

MakeActive

Flag whether this camera should become the active one. Make sure you always have one active camera.

Returns

The created scene node. This pointer should not be dropped. See TReferenceCounted,.Drop() for more information.

Adds a camera scene node with an animator which provides mouse and keyboard control appropriate for first person shooters (FPS).
Overloaded for default parameters.

Parameters

Parent,:

Parent scene node of the camera. Can be nil.

RotateSpeed,:

Speed in degress with which the camera is rotated. This can be done only with the mouse.

MoveSpeed,:

Speed in units per millisecond with which the camera is moved. Movement is done with the cursor keys.

ID,:

id of the camera. This id can be used to identify the camera.

Returns

The interface of the camera if successful, otherwise nil. This pointer should not be dropped. See TReferenceCounted.Drop() for more information.

Adds a camera scene node with an animator which provides mouse and keyboard control appropriate for first person shooters (FPS).
This FPS camera is intended to provide a demonstration of a camera that behaves like a typical First Person Shooter. It is useful for simple demos and prototyping but is not intended to provide a full solution for a production quality game. It binds the camera scene node rotation to the look-at target;
With this camera, you look with the mouse, and move with cursor keys. If you want to change the key layout, you can specify your own keymap. For example to make the camera be controlled by the cursor keys AND the keys W,A,S, and D, do something like this:

    var KeyMap: array[0..7] of TKeyMap;
        Camera: TCameraSceneNode;
    ...
    keyMap[0].Action := kaMoveForward
    keyMap[0].KeyCode := keyUp;
    keyMap[1].Action := kaMoveForward;
    keyMap[1].KeyCode := keyLetterW;

    keyMap[2].Action := kaMoveBackward;
    keyMap[2].KeyCode := keyDown;
    keyMap[3].Action := kaMoveBackward ;
    keyMap[3].KeyCode := keyLetterS;

    keyMap[4].Action := kaStrafeLeft;
    keyMap[4].KeyCode := keyLeft;
    keyMap[5].Action := kaStrafeLeft;
    keyMap[5].KeyCode := keyLetterA;

    keyMap[6].Action := kaStrafeRight;
    keyMap[6].KeyCode := keyRight;
    keyMap[7].Action := kaStrafeRight
    keyMap[7].KeyCode := keyLetterD;

    Camera := SceneManager.AddCameraSceneNodeFPS(0, 100, 500, -1, KeyMap, 8);
                

Parameters

Parent,:

Parent scene node of the camera. Can be nil.

RotateSpeed,:

Speed in degress with which the camera is rotated. This can be done only with the mouse.

MoveSpeed,:

Speed in units per millisecond with which the camera is moved. Movement is done with the cursor keys.

ID,:

id of the camera. This id can be used to identify the camera.

KeyMapArray,:

Optional pointer to an array of a keymap, specifying what keys should be used to move the camera. If this is null, the default keymap is used. You can define actions more then one time in the array, to bind multiple keys to the same action.

KeyMapSize,:

Amount of items in the keymap array.

NoVerticalMovement,:

Setting this to true makes the camera only move within a horizontal plane, and disables vertical movement as known from most ego shooters. Default is 'false', with which it is possible to fly around in space, if no gravity is there.

JumpSpeed,:

Speed with which the camera is moved when jumping.

InvertMouse,:

Setting this to true makes the camera look up when the mouse is moved down and down when the mouse is moved up, the default is 'false' which means it will follow the movement of the mouse cursor.

MakeActive

Flag whether this camera should become the active one. Make sure you always have one active camera.

Returns

The interface of the camera if successful, otherwise nil. This pointer should not be dropped. See TReferenceCounted.Drop() for more information.
