open flood for SFOS

This is an open flood game implementation, inspired and with bits from GunshipPenguin.

This game is mainly a tech demo of sailing-to-coffee. Thus it tries to explore how usable native compiled shared java libraries are for SailfishOS applications.

The maximum fieldsize has been increased to 250x250 for fun, and to show performance

Implementation notices

The java part serializes the game state with flatbuffers to transmit less data and sends it to the c++ part. The flatbuffer definition is in java-part/src/main/resources. It can be updated with the script in java-part/flatbuffers.sh (make sure, that the installed version of flatc matches the header files in qt-part/lib.

For performance reasons, the gamestate is directly parsed in c++ and the gamepanel is drawn from c++ as well.

Future Plans / Ideas

Technical

• Save scores with sqlite

Gameplay

• Count scores
  • combo size score
  • least moves
  • most moves with always progressing
  • ... inspire people to be creative
• Different field patterns with blocks
• 2 Player mode
• Play against bots (and maybe let people submit bots to get them engaged)
• Inspire people to do stupid stuff by manipulating the gamefield, e.g. display videos
• Music?
• Color schemes?
• Levels?
• field tiles that are harder to transform. e.g. switch color on first break

Building

Prerequisites

You'll need graalvm working on your phone. See sailing-to-coffee for further instructions.

1. run git submodule init in this repo
2. install pkcon install gcc glibc-devel zlib-devel libstdc++-static to your aarch64 phone
3. download graalvm to your phone

Building

The java part needs to be built first. Adjust the compile.sh script to your needs. You'll need the prequesits (graal native) on your phone. Cross compilation is not yet possible with graal native.

Afterwards build the qt part with the sailfish ide. This links with the java part.

See sailing-to-coffee for further instructions. The concrete implementation differs quite a lot, see implementation notes above for that.
