Fall Moon

Fall Moon is a 2D block pusher puzzler, themed after the Chinese Moon festival. The player has control over a paper dragon, who’s body can be extended and retracted. The player must put the moon in place by pushing it and doing it in as few moves as possible to get the highest score.

Grid
Grid

The grid is a collection of imaginary points, sorted in a way to allow each point to have coordinates. This is called a 2D array. Using this it is easy for tiles to move on the grid, as they only have to take their own coordinates and change it slightly to get an adjacent point.

Level Editor

Fall Moon being a single screen puzzle game meant it needed a lot of levels to function. One of my main priorities was to make a system in which our two level designers could create levels with ease.

To do this I made a level editor. The editor could easily change the size of the grid, and made it so you could press a button to align all tiles to the grid. These features allowed the level designers to quickly make and iterate levels. A lot of coordinate and location data was also set up here, making the game itself having to setup less when you play it.

Basic Tile

The dragon was supposed to function the same way the entire game, so the puzzles would be constructed from the layout of blockers and the use of different types of tiles. As we weren’t entirely sure what kind of tiles we wanted, i made a Basic Tile script from which all tiles inherited from which could quickly be expanded upon.

Each tile posses the same functions, allowing them to move and push other tiles. It can also be set if they should fall or not and if they should be entirely stationary, to act like a blocker. This all made it easy to add new tiles with slightly different behaviour, and allowed for much easier implementation of special tiles, like the moon that should end the level when it reaches the goal.

Dragon
Dragon Input

The dragon has two control methods to accommodate different playstyles. If you touch the dragon’s head directly, the dragon will try to follow your finger. This is a more accurate way of controlling the dragon but requires you to move your fingers a lot.

If you instead touch anywhere else on the grid the dragon will move with your finger, so if you swipe to the left, the dragon will move that much to the left. This allows the player to play more casually by simply moving their thumb, but with less accuracy.

Dragon Body

The dragon’s head inherits from the Basic Tile script and can be moved in any direction. It also spawns a body part behind it everytime it moves. All body parts are added to a list and if the player is trying to move into the last placed body part, the one behind the head, it will instead remove that tile.

The body parts keep track of what direction the previous one and the next body part is relative to it. It uses these directions to choose from a array of sprites, all with directions attached to them, which one is most suitable to use.

All body parts are also kept in a pool, as instantiating objects drains a phone’s battery power. By keeping them in a pool, the amount of times needed to instantiate a dragon part is massively decreased

Post-Mortem

This project gave me a great chance to make tools and systems for the other designers to use, like the Level Editor. Making a game for a mobile device was also a fun and interesting challenge as it is something i have never done before, forcing me to quickly learn and adapt to something new. As we were also coming up with ideas as we went on, it made me create scripts that were easy to iterate and implement further upon.
