使用不同的节点运行 SKActions 序列 [英] Run SKActions sequence with different nodes

问题描述

我知道我可以创建一个 SKAction.sequence，它会一个一个地运行一个节点的动作.但是，如果我想用不同的节点做一个序列，我该怎么做.我想做这样的事情:

I know that I can create an SKAction.sequence which will run the actions of one node one by one. But how can I do that if I want to do a sequence with different nodes. I'd like to do something like that:

1. 从节点 A 运行操作
2. 等待 2 秒
3. 从节点 B 运行操作.

推荐答案

如果两个节点都是唯一命名的并且是同一个节点的子节点，可以使用runAction:onChildWithName:，如下:

If both nodes are uniquely named and are children of the same node, you can use runAction:onChildWithName:, as follows:

SKAction *action = [SKAction sequence:
    @[[SKAction runAction:[SKAction moveTo:CGPointMake(200.0f, 200.0f) duration:1.0f]
          onChildWithName:@"NODEA"],
      [SKAction waitForDuration:2.0f],
      [SKAction runAction:[SKAction moveTo:CGPointMake(200.0f, 200.0f) duration:1.0f]
          onChildWithName:@"NODEB"]]];

[parent runAction:action];

更一般地，您可以使用 runBlock: 作为 SKAction 序列中的一个步骤来执行几乎所有操作:

More generally, you can use runBlock: to do pretty much anything as a step in an SKAction sequence:

SKAction *action = [SKAction sequence:
    @[[SKAction runBlock:^{
          [nodeA runAction:[SKAction moveTo:CGPointMake(200.0f, 200.0f) duration:1.0f]];
      }],
      [SKAction waitForDuration:2.0f],
      [SKAction runBlock:^{
          [nodeB runAction:[SKAction moveTo:CGPointMake(200.0f, 200.0f) duration:1.0f]];
      }]]];

[parent runAction:action];
