两个不同对象的CCActionSequence

Question

I want to move two different objects, pane1 and pane2, simultaneously using CCActionMoveTo, and I want to call a function once these two objects finish moving.

CCActionMoveTo * actionMove1 =  [CCActionEaseOut actionWithAction:
                               [CCActionMoveTo actionWithDuration:.4
                                               position:ccp(pane1.position.x - 150, 0)]
                                               rate: 1.5];


CCActionMoveTo * actionMove2 =  [CCActionEaseOut actionWithAction:
                                [CCActionMoveTo actionWithDuration:.4
                                                          position:ccp(pane2.position.x - 150, 0)]
                                                            rate: 1.5];

[pane1 runAction: actionMove1];
[pane2 runAction: actionMove2];
[self generateTerrain];

How do I call these two actionMoves at the same time and wait until both are done to call generateTerrain?

Answer 1

I would solve this by just making a timer that calls generate terrain after .4 seconds like this

NSTimer* myTimer = [NSTimer scheduledTimerWithTimeInterval: 0.4 target: self
                               selector: @selector(generateTerrain:) userInfo: nil repeats: NO];

As for executing the animations simultaneously, the code you have should run them at the same time as they are on different nodes

Hope that helps!
