Text Based Game(C++): CatchEmAll

Link to github: https://github.com/coffee-enthusiast/CatchEmAll

A micro-version of Pokemon made in C++!!

In Order the player to travel to different locations with different actions available there I implemented a State Machine with each state representing each location(ie. Arena, Doctor, Gym, etc.)

class State
{
public:
	State(StateMachine* sM, Map* m);
	State();
	~State();
	StateMachine* stateM;
	Map* map;

	virtual void EnterState() = 0;
	virtual void HandleInput() = 0;
	virtual void Update() = 0;
	virtual void ExitState() = 0;
};

When player changes location the following code gets executed:

void StateMachine::ChangeState(State* newState)
{

	if(currentState != nullptr)
		currentState->ExitState();

	currentState = newState;

	currentState->EnterState();
}

Here is what the Home location state looks like:

/*-- HomeState.h ----*/
class HomeState : public State
{
private:

	Player* p_Player;
public:
	HomeState(StateMachine* sM, Map* m, Player* p);
	HomeState();
	~HomeState();

	void EnterState();
	void HandleInput();
	void Update();
	void ExitState();

	bool gameEnds;
	void PrintHelp();
private:

};

/*-- HomeState.cpp ----*/
void HomeState::HandleInput()
{
	int input = getchar();
	if (input == 'h')
	{
		PrintHelp();
	}
	else if (input == 'a')
	{
		stateM->ChangeState(map->arenaLocation);
	}
	else if (input == 'd')
	{
		stateM->ChangeState(map->doctorLocation);
	}
	else if (input == 'w')
	{
		stateM->ChangeState(map->walkLocation);
	}
	else if (input == 'e')
	{
		gameEnds = true;

	}
	else if (input == 'p')	// Print Creatures command
	{
		p_Player->PrintMyCreatures();
	}
}

Finally here is a glimpse of battle between player and ai:

void Battle::rivalAttacks()
{

	// If chosenEntity is effective againt opponent then Use a Move
	if (aiChooseAction() == 0)
	{
		// Choose a random move
		Move myMove;
		do
		{
			myMove = rivalChosenEntity->myMovesQuad.GetMove(rand() % rivalChosenEntity->myMovesQuad.size);
		} while (myMove.name == "");

		if(myMove.category == "Physical")
		{
			// Calculate and Take damage from the rival entity

			cout << rival->getName() << " used " << myMove.name << "!" << endl;
			float damage = rivalChosenEntity->getAttack() + myMove.power - playerChosenEntity->getDefence();
			damage *= (float)myMove.accuracy / (float)100;
			damage *= effectiveAgainstType(rivalChosenEntity->getType(), playerChosenEntity->getType());
			damage /= (float)5;
			playerChosenEntity->TakeDamage(damage);

			rivalChosenEntity->changePowerPoints(myMove.powerPoints);
			
			cout << playerChosenEntity->getName() << " lost " << to_string(damage) << " HP!" << endl;

			if (playerChosenEntity->getHealth() <= 0)
			{
				cout << playerChosenEntity->getName() << " fainted!" << endl;

				rivalChosenEntity->addExpPoints(8);
				playerAliveLeft--;
				if (playerAliveLeft == 0)
				{
					battleEnded = true;
					whoWon = rival;
				}
			}
		}
	}
	

}
