关于准备之前和别人讨论过。根据英文描述,你必须等你准备的动作结束才能执行。大概就是预备动作描述的都是xxx结束后,你要xxx。
比如:
1.所以我想问一下,如果某生物A在做某动作B,在他做这一动作的过程中,如果触发了其他生物的预备动作,那么A还必须完成B这一动作嘛?
你不能在A做B做到一半的时候执行预备动作,只能等A做完B才能执行预备动作。
2.比如说地精打算移动到我身边,他走到一半突然发现眼前出现了一道虹光法墙,他还要继续走完之前预定的路线嘛?
你可以预备地精移动到你身边10尺时,对身边5尺距离开一道墙,那么这个时候地精可以不继续往前走。
3.如果龙的尾巴抽向我(使用尾巴向我攻击),他的尾巴已经移动过来了(已经在进行攻击了),但我和她之间突然出现了一道红光法墙,龙还必须完成这次抽击嘛?如果她能多次抽打,且她本来计划使用多次抽打,那她还需要完成所有抽打嘛?
你可以预备龙打你,你开墙,龙的多打下,打你一下后,你可以开墙,然后龙可以选择放弃打你。
大佬你说的这个“你不能在A做B做到一半的时候执行预备动作,只能等A做完B才能执行预备动作。”可能是误会我的意思了。我知道准备动作是当某件事发生后才有反应。
现在的问题是,如果我描述的trigger是某个动作的一半,那么会发生什么?我看了一下原文,他只要求这个trigger是perceivable circumstance,并没有说一定要是某个完整的动作。
所以我不说,“当龙用尾巴抽我时,我施放虹光法墙”,而会说,“当龙的尾巴向我抽来,移动了10cm后,我施放虹光法墙。”前者的trigger是龙完成了整个攻击动作;后者是龙刚刚把尾巴抽过来,他虽然还没有完成整个攻击动作,但我描述的trigger已经全部结束了,该我反应了。这个时候龙在我施放虹光法墙之后,能取消自己的动作嘛?

Ready
PHB
p193
Sometimes you want to get the jump on a foe or wait for a particular circumstance before you act. To do so, you can take the Ready action on your turn, which lets you act using your reaction before the start of your next turn.
First, you decide what
perceivable circumstance will trigger your reaction. Then, you choose the action you will take in response to that trigger, or you choose to move up to your speed in response to it. Examples include "If the cultist steps on the trapdoor, I'll pull the lever that opens it," and "If the goblin steps next to me, I move away."
When the trigger occurs, you can either take your reaction right after the trigger finishes or ignore the trigger. Remember that you can take only one reaction per round.
When you ready a spell, you cast it as normal but hold its energy, which you release with your reaction when the trigger occurs. To be readied, a spell must have a casting time of 1 action, and holding onto the spell's magic requires concentration (explained in chapter 10). If your concentration is broken, the spell dissipates without taking effect. For example, if you are concentrating on the web spell and ready magic missile, your web spell ends, and if you take damage before you release magic missile with your reaction, your concentration might be broken.
You have until the start of your next turn to use a readied action.
