It'll probably be confusing if you don't know much about VS
Each view is a scene object (front, back, left,right), to turn left of right the buttons call a script in scene properties to check which view visable, it hide that and unhide the next, hotspots also have conditions to switch them on and off if it isn't supposed to be there in that view..
You need to make sure as you leave one scene you force the previous scene back to its forward view as it can go out of sync
the hardest part is placing hotspots, I found the best way to do the door was to add the image for the door object, draw the object area then remove the image
technically there is a character in the scene, but has no graphics, you must define one otherwise you can't enter anything, do dialog etc
Anyway if you have any questions feel free to ask
And may i offer your first-person template in the german template area? I think it might be very useful... it's just brilliant.
Yes of cause you can add it to the template section
