A c++ console application to reconstruct a clapping game in my middle school. The names of moves are modified to facilitate understanding.

1. Clone the repo.
2. Under Linux, you can simply install it by

$ cd DragonBall
$ make

Then run the game by $ ./DragonBall

Basics and terminology

1. Two players exert moves at the same time in every round.
2. Moves include attack (small, middle and big), save energy, and defense(small, middle and big).
3. There is a key parameter called energy which is the basis for certain moves.

Release of energy
4. During an attack, certain amount of energy is released. 1 energy for small attack, 2 energy for middle attack and 5 energy for large attack.
5. No energy is released during a small defense or middle defense.
6. During a big defense, 3 energy is released.
7. When energy is overused, i.e. negative energy appears, the game is over.

Acquisition of energy & How to win
8. After save energy, 1 energy is added.
9. When a player attacks, there are three ways that the other can survive:
a. Make an attack with higher level (e.g. middle attack--small attack).
b. Make the same attack (e.g. small attack--small attack).
c. Apply corresponding defense (e.g. small attack--small defense).
Otherwise the player who attack wins and the attacked player dies.
10. When the case in 9 a. occurs, the player exerting an attack with higher level wins.
11. When the case in 9 b. occurs, the player who defense absorbs energy released by player who attacks (unilateral absorption).
12. When the case in 9 c. occurs, both player absorb energy released by the other (Mutual absorption).

Examples
Example 1
Round 1
Player A: Save energy. Player B: Save energy.
(Both players have 1 energy after round 1)
Round 2
Plyaer A: Small attack. Player B: Save energy.
Player A wins because player B does not make the same attack(as in 9 a.) or corresponding defense (as in 9.b).

Example 2
Round 1
Player A: Save energy. Player B: Save energy.
Round 2
Player A: Small defense. Player B: Small attack.
(Unilateral absorption. A has 2 energy and B has 0 energy.)
Round 3
Player A: Save energy. Player B: Save energy.
Round 3
Player A: Middle attack. Player B: Small attack.
Player A wins because A makes an attack with higher level.

Example 3
Round 1
Player A: Save energy. Player B: Save energy.
Round 2
Player A: Small attack. Player B: Small attack.
(Mutual absorption. Both player have 1 energy after round 2.)
Round 3
Player A: Save energy. Player B: Save energy.
Round 4
Player A: Small attack. Player B: Middle defense.
Player A wins because the defense by player B does NOT correspond with A's attack.

Example 4
Round 1-5
Player A: Save energy. Player B: Save energy.
Round 6
Player A: Big attack. Player B: Big defense.
(Player A releases 5 energy to attack. Player B releases 3 energy to make big defense.
Unilateral absorption occurs so that A has 0 energy while B has 7 energy after round 6.)
Round 7
Player A: Middle defense. Player B: Big attack.
Player B wins.
