Detailed Description

CCActionTween.

CCActionTween is an action that lets you update any property of an object. For example, if you want to modify the "width" property of a target from 200 to 300 in 2 seconds, then:

id modifyWidth = [CCActionTween actionWithDuration:2 key:"width" from:200 to:300]; [target runAction:modifyWidth]; Another example: CCScaleTo action could be rewritten using CCPropertyAction: scaleA and scaleB are equivalents id scaleA = [CCScaleTo actionWithDuration:2 scale:3]; id scaleB = [CCActionTween actionWithDuration:2 key:@"scale" from:1 to:3];

Since: v0.99.2

Member Function Documentation

◆ create()

static CCActionTween * create	(	float	aDuration,
		const char *	key,
		float	from,
		float	to
	)

static

creates an initializes the action with the property name (key), and the from and to parameters.

◆ initWithDuration()

bool initWithDuration	(	float	aDuration,
		const char *	key,
		float	from,
		float	to
	)

initializes the action with the property name (key), and the from and to parameters.

◆ reverse()

CCActionInterval * reverse ( )

virtual

returns a reversed action

Reimplemented from CCActionInterval.

◆ startWithTarget()

void startWithTarget ( CCNode * pTarget )

virtual

called before the action start. It will also set the target.

Reimplemented from CCActionInterval.

◆ update()

void update ( float time )

virtual

called once per frame.

time a value between 0 and 1

For example:

0 means that the action just started
0.5 means that the action is in the middle
1 means that the action is over

Reimplemented from CCAction.
