CocosCreator 发布安卓原生平台 Shader 如何设置

Creator 3.x
#1

Creator 版本： 3.8.2
目标平台： Android

我在Web平台可以生效 Shader, 执行的 Spine 变色, 调用 shaderChange 函数设置 Shader, 调用 shaderColor 来改变 Shader 参数, 但在原生平台, JSB 里的代码是使用原生不行, 看论坛加的, 现在是 Spine 在原生设置 Shader 直接就消失了~~>_<

/**
 * 设置 Shader
 * 在安卓机上有问题, 会导致 spine 不显示
 * 
 * @param shader 
 */
public shaderChange(shader: EffectAsset | null) {
    if (shader === GSpine.spineDef || shader === null) this.shaderData = { type: GSpineShaderType.Def }
    if (shader) {
        const material = new Material()
        material.reset({ effectAsset: shader })
        this.material = material
        if (JSB) {
            this.setSharedMaterial(material, 0)
            // @ts-ignore 
            // this._renderComponent._updateMaterial()// 报错崩溃
        } else {
            let cache = this['_materialCache']
            for (let key in cache) {
                if (cache[key].effectAsset !== material.effectAsset) {
                    // @ts-ignore
                    cache[key] = material
                    // $g.log(`[Shader Bug]重置了材质, 请检查是否有问题`)
                }
            }
            // this.setSharedMaterial(GSpine.spineColor, 0)
            // this.updateMaterial(GSpine.spineColor)
            // this.activateMaterial(GSpine.spineColor)
        }
    } else {
        if (JSB) {
            const material = new Material()
            material.reset({ effectAsset: GSpine.spineDef })
            this.setSharedMaterial(material, 0)
            // @ts-ignore
            // this._renderComponent._updateMaterial() // 报错崩溃
        } else {
            this.material = null
        }
    }
}

/** 执行变色 */
public shaderColor(color: Color, rate: number) {
    let change = false
    if (this.shaderData.type !== GSpineShaderType.Color) {
        change = true
        this.shaderData = { type: GSpineShaderType.Color, color, rate }
        this.shaderChange(GSpine.spineColor)
    }
    const c_run = !this.shaderData.color.equals(color)
    const r_run = this.shaderData.rate !== rate
    if (change || c_run || r_run) {
        this.shaderData.color = color
        this.shaderData.rate = rate
        if (JSB) {
            let m = this.getSharedMaterial(0)
            if (m) {
                if (change || c_run) m.setProperty('u_color', color)
                if (change || r_run) m.setProperty('u_rate', rate)
            }
        } else {
            let matCaches = this['_materialCache']
            for (let key in matCaches) {
                let m = matCaches[key]
                if (change || c_run) m.setProperty('u_color', color)
                if (change || r_run) m.setProperty('u_rate', rate)
            }
        }
    }
}

解决了，这边记录一下:

web:
let mats = this.skeleton._materialCache;
for(let i in mats) {
    mats [i].setProperty("xxx", 0.5)
}

android:
let mat = this.skeleton.customMaterial;
mat.setProperty("xxx", 0.5);
this.skeleton.updateMaterial();
