cocos2d::CCPointconst&other
)const

Since v2.1.4

Calculates the projection of this over other.

Return value
CCPoint
cocos2d::CCPointrotate(
cocos2d::CCPointconst&other
)const

Since v2.1.4

Complex multiplication of two points (“rotates” two points).

Return value
CCPoint vector with an angle of this.getAngle() + other.getAngle(), and a length of this.getLength() * other.getLength().
cocos2d::CCPointunrotate(
cocos2d::CCPointconst&other
)const

Since v2.1.4

Unrotates two points.
