Action queue/list for NPCs in point and click adventure.

Hi all.

I'm making a point and click adventure in the spirit of the old lucasart games. I need to have a list/queue (FIFO) w$$anonymous$$ch contains a sequence of NPC actions like walkTo, ,giveItem, sayLine and so on. I need to be able to add an action to the list, along with it's parameters, (the dialogue string, duration to display text, text color and so on), but I can't t$$anonymous$$nk of a simple way to do t$$anonymous$$s.

Ideally I'd like to say somet$$anonymous$$ng like:

 actionList.Add(Say, BarKeep, "You drinkin' or just lookin'?", 2.0f, green);
 actionList.Add(walkTo, BarKeep, beerPumpLocation);

Can anyone advise on different ways to approach the issue? I'll code it myself, I'm just looking for advice on the most elegant solution.

I've already looked through t$$anonymous$$s ace video https://www.youtube.com/watch?v=o6CaB-hmqoE&feature=youtu.be but I'm stuck on how to ac$$anonymous$$eve the above format for adding actions.

Thanks

Dan
