Detailed Description

Follow is an action that "follows" a node.

Eg:

layer->runAction(Follow::actionWithTarget(hero));

Instead of using Camera as a "follower", use this action instead.

Since
v0.99.2

returns a clone of action

Reimplemented from Action.

static Follow* create ( Node followedNode,
const Rect rect = Rect::ZERO 
)
static

Creates the action with a set boundary or with no boundary.

Parameters
followedNodeThe node to be followed.
rectThe boundary. If rect is equal to Rect::ZERO, it'll work with no boundary.
bool initWithTarget ( Node followedNode,
const Rect rect = Rect::ZERO 
)

Initializes the action with a set boundary or with no boundary.

Parameters
followedNodeThe node to be followed.
rectThe boundary. If rect is equal to Rect::ZERO, it'll work with no boundary.
bool isBoundarySet ( ) const

returns a new action that performs the exactly the reverse action

Reimplemented from Action.

void setBoudarySet ( bool  value)

alter behavior - turn on/off boundary

virtual void step ( float  dt)
overridevirtual

called every frame with it's delta time. DON'T override unless you know what you are doing.

Reimplemented from Action.

virtual void stop ( )
overridevirtual

called after the action has finished.

It will set the 'target' to nil. IMPORTANT: You should never call "[action stop]" manually. Instead, use: "target->stopAction(action);"

Reimplemented from Action.
