中間部分如何優(yōu)化

actionNodes，ranColors是數(shù)組

callFuncAction: function (node,color,returnAction){
        return cc.callFunc(function(){
            let newNode = node;
            newNode.ranColor = color;
            newNode.returnAction = returnAction;
            newNode.runAction(this.changeColorAction(node))
        },this)
    },
    
    let node = this.actionNodes[0];
    node.ranColor = this.ranColors[0];

    node.returnAction = this.callFuncAction(this.actionNodes[1],this.ranColors[1],this.callFuncAction(this.actionNodes[2],this.ranColors[2],this.callFuncAction(this.actionNodes[3],this.ranColors[3],null)));

    node.runAction(this.changeColorAction(node))
