如何改善3D游戏的角色控制？

由于我从辅助类CharacterControl更改为新的BetterCharacterControl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步骤而无法爬上更高的台阶。

我必须跳过上面不是正确的比赛方式，它应该只是走过去。 旧的帮助器类CharacterControl有一个默认的不滑动方式，只是走过几步，我认为可以通过改变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(); }

我对jmonkeyforum的跟进也有0回复。

Answer 1

为此，您可以更改最大斜率的值：

 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，当在世界上移动1个单位时，角色可以体验到的最大高度变化。 如果你将它设置为步长的大小（或安全性的大于<1），你的角色应该能够走上台阶
