virtual CCObject* copyWithZone ( CCZone *  pZone )

virtual

Reimplemented from CCActionInterval.

static CCOrbitCamera* create ( float  t, float  radius, float  deltaRadius, float  angleZ, float  deltaAngleZ, float  angleX, float  deltaAngleX  )

static

creates a CCOrbitCamera action with radius, delta-radius, z, deltaZ, x, deltaX

bool initWithDuration	(	float	t,
		float	radius,
		float	deltaRadius,
		float	angleZ,
		float	deltaAngleZ,
		float	angleX,
		float	deltaAngleX
	)

initializes a CCOrbitCamera action with radius, delta-radius, z, deltaZ, x, deltaX

void sphericalRadius	(	float *	r,
		float *	zenith,
		float *	azimuth
	)

positions the camera according to spherical coordinates

virtual void startWithTarget ( CCNode *  pTarget )

virtual

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

Reimplemented from CCActionCamera.

virtual 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.
