「网易官方」极客战记（codecombat）攻略-游戏开发2-硬币游戏第 5 步：平衡-game-of-coins-step-5-balance

(点击图片进入关卡)

千里之堤，溃于蚁穴。

简介

在 Pac-man 风格的街机游戏系列的最后一关，我们将平衡游戏。

游戏逻辑准备就绪。 在之前的关卡中，我们使用高英雄速度等非均衡游戏参数而是简化游戏测试的早期阶段。

然而，游戏的最终版本应该是平衡的。 如果太容易，玩家会感到无聊。 如果太难了，那么他们会很沮丧，很快放弃。

为了简化平衡过程，我们已将所有游戏参数移至代码顶部 所以你可以在一个地方看到他们，并迅速做出改变。

目前游戏参数设置为噩梦难度。 尽量让它更容易。 别担心，没有 "ideal" 的参数，也没有正确的答案。

你决定参数应该是多少以及游戏有多难。 尝试使其具有挑战性，但有趣！

使用键盘或鼠标进行播放器控制：

1. W -> 向上
2. S -> 向下
3. A -> 左边
4. D -> 右边
5. 鼠标点击 -> 移动到该点

默认代码

# 游戏测试人员不仅应该发现错误，还要解决平衡问题。

# 游戏参数

# 改变游戏参数来平衡游戏。

# 强化时间需要多长时间（秒）。

# 硬币，蘑菇和食人魔的得分值。

COIN_SCORE = 1 # ∆

MUSHROOM_SCORE = 5 # ∆

DEFEATED_SCORE = 10 # ∆

# 每场比赛时间流逝得分减少多少。

TIME_SCORE = 1 # ∆

# 玩家和食人魔的速度。

HERO_SPEED = 17 # ∆

OGRE_SPEED = 15 # ∆

# 食人魔产生延迟（秒）。

SPAWN_DELAY = 4 # ∆

# 关卡布局

# 障碍和可收集的物品。

概览

尝试逐个更改参数，而不是每次迭代更改所有参数。 当你同时改变几个参数时，很难理解游戏参数的影响。

但是有时游戏参数具有协同作用，只有在将它们一起更改时才能看到结果。 没有正确的答案。 只需测试各种参数并分析结果。
