Unity3D自动生成动画控制（AnimationController）
发表于2018-09-27
上一篇给大家介绍了自动生成动画，这一篇来介绍下如何自动生成动画控制器（AnimationController）。
代码大部分来自于官方代码：
using System.Collections;
using UnityEditor.Animations;
using UnityEngine;
using UnityEditor;
public class CreateAnimatorController : Editor ｛
[MenuItem("Animator/Create Animator Controller")]
static void CreateController()
｛
// Creates the controller
AnimatorController controller = AnimatorController.CreateAnimatorControllerAtPath("Assets/Animation/Motion.controller");
// Add Animation Clips
AnimationClip clip = new AnimationClip ();
clip.frameRate = 24;
AssetDatabase.CreateAsset (clip, "Assets/Animation/Motion.anim");
AssetDatabase.SaveAssets ();
// Add parameters
controller.AddParameter("TransitionNow", AnimatorControllerParameterType.Trigger);
controller.AddParameter("Reset", AnimatorControllerParameterType.Trigger);
controller.AddParameter("GotoB1", AnimatorControllerParameterType.Trigger);
controller.AddParameter("GotoC", AnimatorControllerParameterType.Trigger);
// Add StateMachines
AnimatorStateMachine rootStateMachine = controller.layers[0].stateMachine;
AnimatorStateMachine stateMachineA = rootStateMachine.AddStateMachine("smA");
AnimatorStateMachine stateMachineB = rootStateMachine.AddStateMachine("smB");
AnimatorStateMachine stateMachineC = stateMachineB.AddStateMachine("smC");
// Add Clip
// Add States
AnimatorState stateA1 = stateMachineA.AddState("stateA1");
AnimatorState stateB1 = stateMachineB.AddState("stateB1");
AnimatorState stateB2 = stateMachineB.AddState("stateB2");
stateMachineC.AddState("stateC1");
AnimatorState stateC2 = stateMachineC.AddState("stateC2"); // don’t add an entry transition, should entry to state by default
// Add clip
stateA1.motion = clip;
// Add Transitions
AnimatorStateTransition exitTransition = stateA1.AddExitTransition();
exitTransition.AddCondition(UnityEditor.Animations.AnimatorConditionMode.If, 0, "TransitionNow");
exitTransition.duration = 0;
AnimatorStateTransition resetTransition = rootStateMachine.AddAnyStateTransition(stateA1);
resetTransition.AddCondition(UnityEditor.Animations.AnimatorConditionMode.If, 0, "Reset");
resetTransition.duration = 0;
AnimatorTransition transitionB1 = stateMachineB.AddEntryTransition(stateB1);
transitionB1.AddCondition(UnityEditor.Animations.AnimatorConditionMode.If, 0, "GotoB1");
stateMachineB.AddEntryTransition(stateB2);
stateMachineC.defaultState = stateC2;
AnimatorStateTransition exitTransitionC2 = stateC2.AddExitTransition();
exitTransitionC2.AddCondition(UnityEditor.Animations.AnimatorConditionMode.If, 0, "TransitionNow");
exitTransitionC2.duration = 0;
AnimatorTransition stateMachineTransition = rootStateMachine.AddStateMachineTransition(stateMachineA, stateMachineC);
stateMachineTransition.AddCondition(UnityEditor.Animations.AnimatorConditionMode.If, 0, "GotoC");
rootStateMachine.AddStateMachineTransition(stateMachineA, stateMachineB);
｝
需要添加AnimationClip可以参照代码里面的方法，我就不添加可以使用的示例动画片段了，结合上一篇的内容，我们可以动态的为Prefab创建完整的动画控制器，动画状态，跳转流程，动画片段了。
