* If you want text in your level somewhere, you just open the Popit, select a mouth, and stick it wherever it's needed, and add your text. So you can use this for hint boxes, stories, cut-scenes etc.
* Adding music you add a music box. There was some confusion about music and sound editing possibilities from the E3 coverage, but this seems to be how it is according to Edge: the options on music boxes are to control the song, the audible range, and the volume level of each of the instruments in the music. However, you can also have music boxes that just play a given sound effect. For example, Edge describes granite whoopy cushions that sound a fart when jumped on.
* Scripting is object based too. As Edge says, this is where LBP could have risked losing a lot of players - "the boss battle where people get stuck on and just give up". But, they say, it's not - it's simple stuff that can let you trigger enemy attacks, locked door behavior or NPC behavior. Switches are the main object for scripting. They give an example of a basic Zelda style puzzle made in 15 seconds - a switch tied to a motor. Flip the switch and motor can raise a locked door.
However, there's more kinds of switches than just manual. Motion sensitive ones can act like more conventional passive triggers. E.g. you could have an enemy drop down from the sky when you pass a point - all this behavior control by cogs and pistons linked to the switch.
* There's a lock-and-key switch based on stickers. Use the right sticker(s) to flip the switch.
* There's magnetic switches. Which is totally new to me. You have a pair of switches that can be split between two objects. The switch only triggers when they're brought together. As Edge says: "in a single move, the colour-coded keys and gateways of Gauntlet and a hundred other RPGs are suddenly brought within reach".
* The mechanism for chaining levels together is also revealed - keys. When you build a level, a key for that level is added to your inventory. If you want to link that level to another you're building, just place the key at the end, and players will be warped from one to another. The capability opened by this is pretty great also, in that it needn't just be warping players from the end of one level to the beginning of the next. You could have worlds of multiple depth..e.g. have a key to a doorway of a house, to warp your players to another level representing the inside of the house.
