【中文标题】如何改善我的 3D 游戏的角色控制？【英文标题】：How to improve character control for my 3D game? 【发布时间】：2013-05-22 20:28:40 【问题描述】：自从我从帮助类 CharacterControl 更改为新的 BetterCharacterControl 后，我注意到一些改进，例如推动其他角色正在工作，但我的主角已经开始滑过台阶，无法爬更高的台阶。
我必须跳过上面的步骤，这不是正确的游戏方式，应该只是走过去。旧的辅助类 CharacterControl 有一个默认的不滑动方式，只是跨步，我认为可以通过更改我创建主角的代码来纠正它。
private void createNinja()
ninjaNode = (Node) assetManager
.loadModel("Models/Ninja/Ninja.mesh.xml");
ninjaNode.setShadowMode(RenderQueue.ShadowMode.CastAndReceive);
ninjaNode.setLocalScale(0.06f);
ninjaNode.setLocalTranslation(new Vector3f(55, 3.3f, -60));
ninjaControl = new BetterCharacterControl(2, 4, 0.5f);
ninjaControl.setJumpForce(new Vector3f(6, 6, 6));
ninjaNode.addControl(ninjaControl);
rootNode.attachChild(ninjaNode);
bulletAppState.getPhysicsSpace().add(ninjaControl);
getPhysicsSpace().add(ninjaControl);
animationControl = ninjaNode.getControl(AnimControl.class);
animationChannel = animationControl.createChannel();

【问题讨论】：
【参考方案1】：为此，您需要更改最大斜率的值：
setMaxSlope()
来自 jmonkey 网站：
"How steep the slopes and steps are that the character can climb without considering them
an obstacle. Higher obstacles need to be jumped. Vertical height in world units."
阅读本文，我相信它的工作方式类似于在世界上移动 1 个单位时，角色可以经历的最大高度变化是多少。如果您将其设置为台阶的大小（或为安全起见大于

【讨论】：
感谢您的回答！是的，我想使用setMaxSlope() 是完全正确的，但它似乎在BetterCharacterControl 升级中不可用，这会破坏我的功能。你能告诉我该怎么做吗，它曾经在旧版本中工作得更好，但现在使用BetterCharacterControl 它在角色相互推动时工作。请帮忙，在尝试升级到 BetterCharacterControl 几个月后，我一直被困在这个问题上，现在终于成功了，注意到它破坏了 maxslope 功能。
就是这个类：hub.jmonkeyengine.org/wiki/doku.php/…
嗯，你可以试着在走路时增加一个向上的力量，这不足以抵消重力但足以让它向上推？让我看一下文档，如果有什么我会回复你的。
改变高度百分比可能是要走的路，如果角色从上次移动然后没有提高高度百分比，请检查更新。它可能会减慢上楼梯的速度，我不太清楚。看看 JMonkey，似乎大多数人仍在使用普通的 characterControl，最好采用你喜欢的 betterCharacterControl 并扩展 characterControl 以添加该功能？编辑：刚刚看到 JME3 背后的人说今年 3 月它还不稳定，也许等它成熟后再放吧？
我同意，但 JME 的人确实有他的理由：hub.jmonkeyengine.org/forum/topic/…以上是关于如何改善我的 3D 游戏的角色控制？的主要内容，如果未能解决你的问题，请参考以下文章
