For showing a number of animations sequentially in Cocos2D we use the CCSequence.
CCSequence can accept a number of actions as parameters which will be executed in sequence , ie one after another.
Here is a sample code to so this.
/* This action will scale my_sprite */ id scaleTo = [CCScaleTo actionWithDuration:4 scale:1.5]; /*This action will move the sprite from current position to this point*/ id moveTo = [CCMoveTo actionWithDuration:1.0f position:ccp(size.width/3,size.height/3)]; /* This will execute all the above actions in sequence. */ id sequence=[CCSequence actions:scaleTo,moveTo,nil]; /* Run the above actions for your sprite */ [my_sprite runAction:sequence];
