Detailed Description

A transition which peels back the bottom right hand corner of a scene to transition to the scene beneath it simulating a page turn.

This uses a 3DAction so it's strongly recommended that depth buffering is turned on in Director using:

Director::getInstance()->setDepthBufferFormat(kDepthBuffer16);

Since

v0.8.2

Member Function Documentation

create()

static TransitionPageTurn * create ( float t, Scene * scene, bool backwards )

static

Creates a base transition with duration and incoming scene.

If back is true then the effect is reversed to appear as if the incoming scene is being turned from left over the outgoing scene.

Parameters

t	Duration time, in seconds.
scene	A given scene.
backwards	If back is true then the effect is reversed to appear as if the incoming scene is being turned from left over the outgoing scene.

Returns

An autoreleased TransitionPageTurn object.

draw()

virtual void draw ( Renderer * renderer, const Mat4 & transform, uint32_t flags )

overridevirtual

Override this method to draw your own node.

The following GL states will be enabled by default:

• glEnableClientState(GL_VERTEX_ARRAY);
• glEnableClientState(GL_COLOR_ARRAY);
• glEnableClientState(GL_TEXTURE_COORD_ARRAY);
• glEnable(GL_TEXTURE_2D); AND YOU SHOULD NOT DISABLE THEM AFTER DRAWING YOUR NODE But if you enable any other GL state, you should disable it after drawing your node.

Parameters

renderer	A given renderer.
transform	A transform matrix.
flags	Renderer flag.

Reimplemented from TransitionScene.

initWithDuration()

bool initWithDuration	(	float	t,
		Scene *	scene,
		bool	backwards )

Creates a base transition with duration and incoming scene.

If back is true then the effect is reversed to appear as if the incoming scene is being turned from left over the outgoing scene.

Parameters

t	Duration time, in seconds.
scene	A given scene.
backwards	If back is true then the effect is reversed to appear as if the incoming scene is being turned from left over the outgoing scene.

Returns

True if initialize success.

actionWithSize()

ActionInterval * actionWithSize

(

const Vec2 &

vector

)

Returns the action that will be performed with size.

Parameters

vector

A given size.

Returns

The action that will be performed.

onEnter()

virtual void onEnter ( )

overridevirtual

Event callback that is invoked every time when Node enters the 'stage'.

If the Node enters the 'stage' with a transition, this event is called when the transition starts. During onEnter you can't access a "sister/brother" node. If you override onEnter, you shall call its parent's one, e.g., Node::onEnter(). @lua NA

Reimplemented from TransitionScene.

onExit()

virtual void onExit ( )

overridevirtual

Event callback that is invoked every time the Node leaves the 'stage'.

If the Node leaves the 'stage' with a transition, this event is called when the transition finishes. During onExit you can't access a sibling node. If you override onExit, you shall call its parent's one, e.g., Node::onExit(). @lua NA

Reimplemented from TransitionScene.
