CCEaseIn etc inside CCSequence

Question

How do you exactly use easing inside CCSequence?

Related to Using CCEaseOut together with CCSequence?

Answer 1

here is an example. This brings back my mapNode to the left border, for example when a LHS menu is popped out. Move duration and acceleration are computed as a function of the expected displacement :

- (void)setLeftClamp:(float)leftClamp {

    _leftClamp = leftClamp;

    CGPoint currentPosition = self.mapNode.position;
    if (currentPosition.x > self.maxX) {
        // ease right back in position
        CGPoint delta         = ccp (self.maxX - currentPosition.x, 0);
        id      move          = [CCMoveBy actionWithDuration:[self moveDuration:delta] position:delta];
        id      ease          = [CCEaseIn actionWithAction:move rate:[self moveAcceleration:delta]];
        id      delay         = [CCDelayTime actionWithDuration:.1f];
        id      easeAndCenter = [CCSequence actions:ease, delay, [CCCallFunc actionWithTarget:self selector:@selector(onMoveComplete)], nil];
        [self.mapNode runAction:easeAndCenter];

        targetMapLocation_ = ccpAdd(self.mapNode.position, delta);
        mapDisplacement_   = delta;
        isMapMoving_       = YES;

    }
