Firefly Zero is a modern handheld game console with effortless multiplayer. It's fun to play, alone or with friends, and easy to program.
Install the Firefly Emulator and the Firefly CLI according to these instructions.
Then you can install Blutti with the following command:
firefly_cli import olle.blutti
After that you can start firefly-emulator which will launch the game.
Use Tiled mapeditor to create maps. Load the
project file assets/blutti-spritesheet.tsx. Draw the level in the first tile
layer and add monsters in the first object layer. Use the custom property
movement to set how fast the monster should move. Set a negative values to
make the monster start by moving left.
The map should have the following custom properties:
background_color- A FireflyColor class for the background color of the level.font_color- A FireflyColor class for the font color of text in the level.stars- An int with how many collected stars are needed to finish the level.start_position- A Point class defining the position where the player should start.
Once the map is finished, it can be exported using the Blutti map format to
the assets directory..
The filename (without extension) has to be added to the LEVELS const at the
top of src/main.rs. The position in the array defines when it will show up
in the game. Finally, a reference to the file needs to be added under the
files section in firefly.toml with the attribute copy set to true.
When adding new tiles to the spritesheet, remember to update the COLLISION
array with collision info for each tile.
TileCollider::Full- Tile that player and monsters can't enter.TileCollider::Climbable- Tiles that can be climbed, such as ladders.TileCollider::Star- A collectable star that gives points.TileCollider::ExtraLife- A powerup that gives an extra life.TileCollider::Exit- Used to exit the level when enough stars are collected.TileCollider::Deadly- Tile that the player will die when entering.TileCollider::Slippery- Causes player to slide and be unable to change direction.TileCollider::None- Empty tile that player and monsters can walk through.
