Whether you did maps for AVWW or not, please read through these instructions a bit, as making slices is a bit different than making maps was in the last game.
The slices can be found in *Game Directory*\RuntimeData\Logic\ChunkSlices then each slice type has it's own directory from there.
The biggest difference, and the single most important piece to any slice is the new "SliceConnectorHint". You'll see in the examples already in the game that they will go on the path that the player is expected to move through, at the edges of the slice. These let the game know how the slices are supposed to connect to each other, by connecting one of these blocks to another. Having other paths that don't have these as dead-end are ok.
Another big thing to bear in mind is that the game isn't going to be seeding enemies randomly anymore. This is now the job of the slice creators. One of the new points in the map editor is the placement of different size and types of enemies. Please bear in mind that having more enemies in a slice is preferable to not having enough. The game knows to not seed too many enemies, but, it can only seed ones where it has instructions to do so. Too many enemies isn't really an issue.
Please understand, the focus on the game is meant to be more about combat than platforming, so we aren't really looking for a lot of really hard platforming challenges.
I've made one of our design documents public now, so that you can all see. In it are descriptions of what the slices should be. By and large, the slice types on that list are the ones we're most interested in getting additions for. But, if you want to do other types, please feel free. If you want an official description for a slice type added, please let me know that too. The document can be found here:
https://docs.google.com/document/d/1uEMmE-3Or_OJA3BX7u65h5zR2fqglLAtnU5wx6VV3Sk/edit . This document also describes the uses of the different enemy classes in the game.
If you would like your slices added to the official game, please try to adhere to the descriptions in the above document as closely as possible, as they often server very specific purposes. I will be going over and approving any slices before they go into the game. If I don't approve your slice for the game, please don't take it personally. A few slices that aren't up to par can really ruin one's gaming experience.
That said, not every slice has to be art or has to be the most amazing slice ever. They just need to have some thought put into them.
Other notes of interest. The player normally is two blocks high and one block wide, and needs at least this much space to move. Players can also normally jump 5 blocks high.
The map editor is included with the game, and is the fastest way to edit slices. I'll also be posting specific instructions on using that in another post.
