This code allows you to wait until the user clicks an NPC, then you talk to the NPC, then once finished, it returns you to where you were before. You could click on the NPC over and over again if you want. IMPORTANT: With this code, you can create a scene with arrow navigation/movement as imagebuttons, multiple npc's who wait to be spoken to (represented as imagebuttons), or objects(bucket, hammer) laying about that you can interact with, represented as imagebuttons. The important part is that it always returns to the original waiting for input mode, which Ren'py achieves through the use of call screen.
CLICK FOR ANIMATED GIF PREVIEW - wait 2 seconds for it to kickin. This forum cannot show an animated gif, or maybe it can?

# see where it says ACTION JUMP?? You can perform any action there, like calling a function that moves you to a different location
# or jumps to a conversation with an npc, or jumps to a function after clicking a hammer, etc.

#IMPORTANT - this is the most important part, it returns back to the loop.
# basically what happened is that you saw the npc, clicked on him, he disappears, from the background and can come to the foreground to talk with player
# then after he's done talking, he returns back to the background.
