Unity Animation采样和自定义属性
发表于2018-08-08
介绍Animation采样和自定义Animation属性动画之前，大家需要了解这两部分的内容：
1、了解Animation的采样函数Sample怎么使用。
2、了解自定义属性面板
动画的采样可用于自定义编辑器等工具，也可以自己实现一套动画系统。
首先看一下自定义属性面板，网上都有相关代码和教程，在这里粘贴一处网上的代码，如果冒犯，望海涵~
using UnityEngine;
using System.Collections;
public class MyRangeAttribute : PropertyAttribute
｛
public float min;
public float max;
public string label;
public MyRangeAttribute( float min, float max, string label = "")
｛
this.min = min;
this.max = max;
this.label = label;
｝
｝
using UnityEngine;
using UnityEditor;
using System.Collections;
//该代码放在Editor目录下
[CustomPropertyDrawer(typeof(MyRangeAttribute))]
public class MyRangeAttributeDrawer : PropertyDrawer
｛
public override void OnGUI(Rect position, SerializedProperty property, GUIContent label)
｛
MyRangeAttribute range = this.attribute as MyRangeAttribute;
if( property.propertyType == SerializedPropertyType.Float )
｛
if (range.label != string.Empty)
｛
label.text = range.label;
｝
EditorGUI.Slider(position, property, range.min, range.max, label);
｝
else if( property.propertyType == SerializedPropertyType.Integer )
｛
if( range.label != string.Empty )
｛
label.text = range.label;
｝
EditorGUI.IntSlider(position, property, (int)range.min, (int)range.max, label);
｝
｝
｝
动画采集及自定义属性使用：
using UnityEngine;
using System.Collections;
[ExecuteInEditMode]
public class AnimationTest : MonoBehaviour
｛
public Animation anim;
[MyRangeAttribute(0f,1f,"动画采样")]
public float curValue = 0f;
float deltaTime = 0f;
float lastFrameTime = 0f;
float progressTime = 0f;
string clipName = "run";
void Start ()
｛
anim.enabled = false;
AnimationState state = anim[clipName];
state.enabled = true;
state.weight = 1;
state.normalizedTime = 0;
anim.Sample();
state.enabled = false;
｝
// Update is called once per frame
void Update ()
｛
deltaTime = Time.realtimeSinceStartup;
progressTime += deltaTime - lastFrameTime;
Example();
lastFrameTime = deltaTime;
｝
void Example()
｛
AnimationState animState = anim[clipName];
animState.enabled = true;
animState.speed = 1f;
animState.weight = 1;
if (curValue > 1f)
｛
curValue = 0f;
｝
animState.normalizedTime = curValue;
anim.Sample();
animState.enabled = false;
｝
｝
这样就可以自由操作动画的播放了：
