fusion

description

  • Fusion is a circular variant of tetris.

code

  • The code is written in C++.
  • All the source code is in src/.
  • Any generated outputs are stored in data/.
  • Simplecpp is used for rendering.
  • include & lib contains headers and implementation of simplecpp.

documentation

  • The documentation for the code is itself.

usage

how to run? [linux]

  • Make sure x11 and x11-dev are installed.
  • Open terminal in the root directory.
    • Make a build directory using mkdir build && cd build.
    • Create a makefile using cmake ..
    • Compile code using make. This creates an executable named fusion.
    • Use ./fusion to start playing.

rules

  • The game board is circular.
  • An element (from the periodic table) pops up in the center randomly.
  • It can be placed anywhere on the circular board with a mouse click. Once placed, the ones on the board space themselves out equally.
  • As one element is placed, a new element pops up again in the center.
  • Sometimes a special element + pops up.
    • Once placed in circle, It has the power to fuse elements.
    • But for fusion to occur elements on either side of + should be mirror images.
    • For example, if board has H (1) + H (1), then both H fuse to give He (2).
    • More than one pair of elements can be fused at a time.
    • For example, He (2) H (1) + H (1) He (2) gives Be (4).
    • Bigger combos generate bigger elements.
    • Even +'s can be fused. + + + gives H (1).
  • Every time a fusion occurs you get some points based on the size of the combo.
  • Notice the number of elements decrease when fusion occurs.
  • If the number of elements on the board exceed 12 the game ends.
  • So the goal is to keep the fusion going and prevent that.
  • Place, fuse and repeat to score the highest.
  • Scores are recorded in a file. For this a you will be prompted to enter a handle at the beginning.
  • Concept taken from Atomas.

demonstration

The following gifs illustrates the gameplay.

  • Single fusion H (1) + H (1) => He (2).

  • Single fusion He (2) + He (2) => Li (3).

  • Multi fusion He (2) H (1) + H (1) He (2) => Be (4).

  • Multi fusion He (2) He (2) + He (2) He (2) => B (5).

  • Multi fusion He (2) H (1) + H (1) He (2) => Be (4).

  • Bad placement.

  • Full gameplay.

roadmap

  • Basic game.
    • rayAngle()
    • 120 element symbols and colors.
    • Decouple file i/o from game logic.
    • Bubbling effect while fusing.
    • Implement good data structure for maintaining game state. Round Table Conference Structure i.e. Circular double linked list.
    • Random new atomic number based on max atomic number achieved. Use normal dist with mean = 0.5 max achieved, std = 1.
  • Fix high score logic.
  • Improve game experience.
    • Highest Element achieved.
    • Element Symbol.
    • Score.
    • Randomness.
    • + element.
    • Colors.
    • Place the first element on top instead of right side.
    • It's better to provide a restart option after game-over instead of closing the window.
    • Show the scoreboard on the terminal along with current score and rank.
  • Close canvas properly.
  • Fix stoi bug.
