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.
