Alright I am having trouble with a few things in Rpgmaker XP and they are as follow.

1) Day and night
2)talking
3) door and chest animations


Details:

1) How do I go about making day and night?

2) When I do an automatic sequence how do I make my character and the others talk in order and by themselves?

3)How do I make the chest open and doors open when my character acts upon them?
