Ok by now a lot of ppl helped me and and i thank everyone about that, but now i have a problem and not a scripting problem its more like how i do this, i wanted to create some chars and when talked with them make another screen with bigger aproach of their faces like torso up only, and display conversation in a black box in the screen and at the same time showing animations of theyr speech and able to interact with anything in the screen while we talk, create a new room that opens when talked with small chars? make hotspots for the interactions? design the bodys as backgrounds and insert only new characters that are only the head, im little confused cause i didnt found any tutorial about this, there some screens to explain better, and sorry about my english.
