AssetPostprocessor.OnPostprocessGameObjectWithAnimatedUserProperties(GameObject, EditorCurveBinding[])

参数

描述

当自定义属性的动画曲线已完成导入时调用此函数。

对于具有动画自定义属性的每个游戏对象都会调用它。每个动画属性都有一个由 EditorCurveBinding 表示的动画曲线。这使您可以动态地将组件添加到游戏对象，并将 EditorCurveBindings 重新定位到任何可动画化的属性。

using UnityEngine;
using UnityEditor;

class MyAllPostprocessor : AssetPostprocessor
{
    void OnPostprocessGameObjectWithAnimatedUserProperties(GameObject go, EditorCurveBinding[] bindings)
    {
        // add a particle emitter to every game object that has a custom property called "particleAmount"
        // then map the animation to the emission rate
        for (int i = 0; i < bindings.Length; i++)
        {
            if (bindings[i].propertyName == "particlesAmount")
            {
                ParticleSystem emitter = go.AddComponent<ParticleSystem>();
                var emission = emitter.emission;
                emission.rateOverTimeMultiplier = 0;

                bindings[i].propertyName = "EmissionModule.rateOverTime.scalar";
                bindings[i].path = AnimationUtility.CalculateTransformPath(go.transform, go.transform.root);
                bindings[i].type = typeof(ParticleSystem);
            }
        }
