c# - 无法获得退出和跳过正确打开按键的方法
问题描述
所以我正在为一个班级构建这个 RPG 回合制游戏。我不是想为我完成我的家庭作业,但这个问题真的让我很困惑,我已经在这个问题上待了 3 个小时,我不知道如何解决这个问题。
本质上,我有一个更新方法来控制它是谁(播放器或计算机)
public bool Update()
{
// clears console for a fresh start
Console.Clear();
//branch who's turn it is and add a line indicating so
if (playerTurn)
{
//print that it's the player's turn
Console.WriteLine("It's Your Turn to Attack!");
//run the player turn
PlayerTurn();
}
else
{
//print the rivals turn label
Console.WriteLine("It's the Enemy's Turn to Attack!");
}
//run the rivals turn
RivalsTurn();
{
}
//end game check
return EndTurn();
}
然后,我有玩家回合方法---
void PlayerTurn()
{
// print instructions to select an attacker
Console.WriteLine($"Select which character will attack!\n(1) To Select {playerArray[0].Name()}\n(2) To Select {playerArray[1].Name()}\n(3) To Select {playerArray[2].Name()}\n(4) to view your teams current status\n(5) To Heal An Ally");
// Loop until an attacker is chosen
while (Attacker == null)
{
// use num 1-3 to select player party member that is the attacker
ConsoleKeyInfo k = Console.ReadKey();
if (k.KeyChar == '1')
{
Attacker = playerArray[0];
Console.WriteLine($"\nYou've chosen to attack with {Attacker.Name()}");
}
else if (k.KeyChar == '2')
{
Attacker = playerArray[1];
Console.WriteLine($"You've chosen to attack with {Attacker.Name()}");
}
else if (k.KeyChar == '3')
{
Attacker = playerArray[2];
Console.WriteLine($"You've chosen to attack with {Attacker.Name()}");
}
else if(k.KeyChar == '4')
{
PrintParties();
continue;
} else if (k.KeyChar == '5') {
HealAlly();
break;
}
// start a new line after user input
Console.WriteLine();
// Data Validation: make sure the key typed is a valid key
if (k.KeyChar < '1' || k.KeyChar > '5')
{
Console.WriteLine("Please Enter (1), (2), or (3) to select your attacking character. Press (4) to view your stats, and (5) to Heal an Ally");
continue;
}
else // convert from key input (1-3) to array element space (0-2)
curSelection = int.Parse(k.KeyChar.ToString()) - 1;
{
}
if (Attacker.GetHP() <= 0)
{
//check to make sure the selected character is alive HP > 0
//print the attackers name
//character's dead choose again
Console.WriteLine($"{Attacker.Name()} is dead! Choose someone who is alive!");
Console.WriteLine("Please Enter (1), (2), or (3) to select your attacking character. Press (4) to view your stats, and (5) to Heal an Ally");
Attacker = null;
}
else
{
Console.WriteLine($"{Attacker.Name()} will attack!");
Thread.Sleep(1000);
}
}
//print instructions for choosing a rival.
Console.WriteLine($"Select which enemy to attack!\n(1) To Attack {enemyArray[0].Name()}\n(2) To Attack {enemyArray[1].Name()}\n(3) To Attack {enemyArray[2].Name()}\n(4) To see the Enemies Current Stats.");
//loop until a defender is choosen
while (Defender == null)
{
// use 1-3 to select player party member that is the attacker
ConsoleKeyInfo k = Console.ReadKey();
if (k.KeyChar == '1')
{
Defender = enemyArray[0];
Console.WriteLine($"\nYou will attack {Defender.Name()}");
} else if(k.KeyChar == '2') {
Defender = enemyArray[1];
Console.WriteLine($"\nYou will attack {Defender.Name()}");
}
else if (k.KeyChar == '3')
{
Defender = enemyArray[2];
Console.WriteLine($"\nYou will attack {Defender.Name()}");
} else if (k.KeyChar == '4')
{
playerTurn = false;
PrintParties();
playerTurn = true;
}
{ }
//add a new line aft er the user input
Console.WriteLine();
// Data Validation: make sure the key typed is a valid key
if (k.KeyChar < '1' || k.KeyChar > '3')
{
// repeat instructions
Console.WriteLine("Select an enemy to attack by pressing either 1, 2, or 3.\n");
// loop again
continue;
}
else // convert from key input (1-3) to array element space (0-2)
curSelection = int.Parse(k.KeyChar.ToString()) - 1; //minus one to use as index
//check to make sure the selected character is alive HP > 0
//print the defenders name
//assign the selected character as the defender
if (Defender.GetHP() <= 0)
{
//print instructions again
Console.WriteLine($"{Defender.Name()} is already dead! Pick another enemy!");
Console.WriteLine("Select an enemy to attack by pressing either 1, 2, or 3.\n");
Defender = null;
} else
{
Console.WriteLine($"{Attacker.Name()} attacks {Defender.Name()}!");
Thread.Sleep(2000);
}
}
//damage the defender by the attacker's Strength value
Defender.ApplyDamage(Attacker.GetStrength());
//change color for rival team
Console.BackgroundColor = Attacker.GetTeamColor();
//print the new rival's health
Console.WriteLine($"{Defender.Name()} was hit by {Attacker.Name()}! {Defender.Name()} now only has {Defender.GetHP()} HP!");
EndTurn();
//change color back for normal
Console.BackgroundColor = ConsoleColor.Black;
//pause for 2 seconds
Thread.Sleep(2000);
//reset attacker/defender for next attack
Attacker = null;
Defender = null;
}
我要做的是当玩家选择“5”并运行 HealAlly() 方法时,我希望程序接受用户的下一个输入(要治疗的人),告诉玩家他们是否可以治愈(如果角色要么死亡,要么完全健康),然后切换回合。
相反,代码跳回到 PlayerTurn 方法的中间并尝试从那里执行,但由于从未设置攻击者(用户点击 5,所以他们没有选择攻击者)游戏将崩溃。
这是 HealAlly() 方法:
void HealAlly()
{
float healing = 3;
while (Healee == null)
{
Console.WriteLine("\nWhich Ally Do You Want To Heal?");
Console.WriteLine($"(1) for {playerArray[0].Name()}\n(2) for {playerArray[1].Name()}\n(3) for {playerArray[2].Name()}");
// use 1-3 to select player party member that is being healed
ConsoleKeyInfo k = Console.ReadKey();
if (k.KeyChar == '1')
{
Healee = playerArray[0];
Console.WriteLine($"\nYou will heal {Healee.Name()}");
Console.WriteLine("Healing...");
}
else if (k.KeyChar == '2')
{
Healee = playerArray[1];
Console.WriteLine($"\nYou will heal {Healee.Name()}");
Console.WriteLine("Healing...");
}
else if (k.KeyChar == '3')
{
Healee = playerArray[2];
Console.WriteLine($"\nYou will heal {Healee.Name()}");
Thread.Sleep(1000);
Console.WriteLine("Healing...");
}
else if (k.KeyChar > 3 || k.KeyChar < 1)
{
Console.WriteLine("Choose which character you want to heal!");
continue;
}
if (Healee.GetHP() >= 12)
{
Thread.Sleep(1000);
Console.WriteLine($"{Healee.Name()} has full health! You can't heal them!");
EndTurn();
}
else if (Healee.GetHP() <= 0)
{
Thread.Sleep(1000);
Console.WriteLine($"{Healee.Name()} is dead! You can't heal them!");
EndTurn();
}
else
{
Healee.ApplyHealing(healing);
Thread.Sleep(2000);
Console.WriteLine($"{Healee.Name()} has been healed, and now has {Healee.GetHP()} HP!");
EndTurn();
}
我认为在 HealAlly() 方法的末尾添加对 EndTurn() 的调用会导致转弯结束,但它所做的只是给我延迟消息,然后返回到 PlayerTurn() 方法的中间. 我确定这是因为没有设置攻击者,但这不是我想要的,因为我不希望玩家在治疗后能够攻击。
如果有帮助,这里是 EndTurn() 方法
bool EndTurn()
{
//switch turns for next loop
playerTurn = !playerTurn;
// loop through players to see if they're alive and store in a variable counting if they're alive or not
bool playersAlive = true;
for (int i = 0; i < playerArray.Length; i++)
{
if (playerArray[0].GetHP() <= 0 && playerArray[1].GetHP() <= 0 && playerArray[2].GetHP() <= 0)
{
playersAlive = false;
}
}
// same for rivals
bool rivalsAlive = true;
for (int i = 0; i < enemyArray.Length; i++)
{
if (enemyArray[0].GetHP() <= 0 && enemyArray[1].GetHP() <= 0 && enemyArray[2].GetHP() <= 0)
{
rivalsAlive = false;
}
}
// if both have things alive start the next round, pause the game, and return true to continue playing
if (playersAlive && rivalsAlive)
{
Console.WriteLine("Next Round Starts in 5 seconds");
Thread.Sleep(5000);
return true;
} // if only the players have members alive you win
else if (playersAlive)
{
//clear screen for results
Console.Clear();
//print you've won and parties
Console.WriteLine("Congrats you win! Final Standings:");
playerTurn = false;
PrintParties();
playerTurn = true;
PrintParties();
Thread.Sleep(5000);
Console.WriteLine("Thanks For Playing!");
Console.WriteLine("Press Any Key to Play Again");
Console.ReadKey();
Console.Clear();
Init();
return false;
} // only rival members are alive
else
{
//clear screen for results
Console.Clear();
//Print you've lost and parties
Console.WriteLine("You Lose :( Final Standings:");
playerTurn = false;
PrintParties();
playerTurn = true;
PrintParties();
Thread.Sleep(5000);
Console.WriteLine("Thanks For Playing!");
Console.WriteLine("Press Any Key to Play Again");
Console.ReadKey();
Console.Clear();
Init();
return false;
}
}
这让我很烦,有人可以帮忙吗?
解决方案
void PlayerTurn()
{
// ...
while (Attacker == null)
{
// ...
if (k.KeyChar == '5') {
HealAlly();
break;
}
}
// ...code that depends on Attacker...
}
此处的break
语句仅导致流程跳出while
循环并继续执行依赖于攻击者的代码。如果您想PlayerTurn()
完全离开该方法,break;
请将return;
