Egret之龙骨卡槽(slot)换皮

标签：oss   配置   instance   struct   hang   elf   isp   通过   idt   

换皮的核心代码:

    //针对slot设置其新内容
    private setNewSlot( slotName:string, textureName:string )
    {
        //方法1
        var slot:dragonBones.Slot = this._armature.getSlot( slotName );
        var b:egret.Bitmap = new egret.Bitmap();
        b.texture = RES.getRes( textureName );
        b.x = slot.display.x;
        b.y = slot.display.y;
        b.anchorOffsetX = b.width/2;
        b.anchorOffsetY = b.height/2;
        slot.setDisplay( b );

        //方法2，仅限于slot中内容为Bitmap
        //var slot:dragonBones.Slot = this._armature.getSlot(slotName);
        //slot.display.texture = RES.getRes(textureName);
    }

我做了一个工具:

module bg2tool{
    /**
     * 碧鸽龙骨动画工具--单例
     * @author Husz
     */
    export class DragonBoneAnimationTools{
        private static _instance : DragonBoneAnimationTools = null;

        /**
         * 获取单例(只读......)
         * @returns {bg2tool.DragonBoneAnimationTools}
         * @constructor
         */
        public static get Instance() : DragonBoneAnimationTools{
            if( DragonBoneAnimationTools._instance == null ){
                DragonBoneAnimationTools._instance = new DragonBoneAnimationTools();
            }
            return DragonBoneAnimationTools._instance;
        }

        /**
         * 防止类外实例化
         */
        private constructor(){}

        /**
         * 设置骨骼卡槽的皮肤
         * @param {dragonBones.EgretArmatureDisplay} $animation 骨骼动画
         * @param {string} $slotName 卡槽名称
         * @param {string} $textureName 纹理
         */
        public setNewSlot( $animation : dragonBones.EgretArmatureDisplay ,  $slotName:string, $textureName:string ) : void{
            if( DEBUG ){
                if( !RES.hasRes($textureName) ){
                    egret.error(`骨骼动画卡槽换装 ${$textureName} 纹理没有配置!!!`);
                }else{
                    if( RES.getRes( $textureName ) == null ){
                        egret.error(`骨骼动画卡槽换装 ${$textureName} 纹理没有被加载!!!`);
                    }
                }
            }
            let slot:dragonBones.Slot = $animation.armature.getSlot($slotName);
            let b:egret.Bitmap = new egret.Bitmap();
            b.texture = RES.getRes( $textureName );
            b.x = slot.display.x;
            b.y = slot.display.y;
            b.anchorOffsetX = b.width>>1;
            b.anchorOffsetY = b.height>>1;
            slot.display = b;
        }
    }
}

现在准备测试

①: 准备龙骨资源

注意:
球的图片资源绑定的卡槽名称为 slot

看看初始骨骼动画效果:

private $dragonBone : dragonBones.EgretArmatureDisplay = null;

                this.$dragonBone = bg2tool.DragonBonePoolResManager.Instance.getAnimation4DragonBone(
                    "GuajiSelfBone_ske_json",
                    "GuajiSelfBone_tex_json",
                    "GuajiSelfBone_tex_png",
                    "guajiAnimation",
                    1,
                    1
                );
                this._context.GuajiAnimation.addChild( this.$dragonBone );

                this.$dragonBone.x = 200;
                this.$dragonBone.y = 400;

                this.$dragonBone.animation.play("jumping",0);

结果:

换皮开始:
换成:

代码:

                this.$dragonBone = bg2tool.DragonBonePoolResManager.Instance.getAnimation4DragonBone(
                    "GuajiSelfBone_ske_json",
                    "GuajiSelfBone_tex_json",
                    "GuajiSelfBone_tex_png",
                    "guajiAnimation",
                    1,
                    1
                );
                this._context.GuajiAnimation.addChild( this.$dragonBone );

                this.$dragonBone.x = 200;
                this.$dragonBone.y = 400;

                this.$dragonBone.animation.play("jumping",0);

                bg2tool.ResSyncLoadingManager.Instance.startLoading( "1-1_99003_png" , this.changeSkin.bind(this) );

                        private changeSkin( $skin : string ) : void{
                                    if( $skin == "1-1_99003_png" ){
                                            bg2tool.DragonBoneAnimationTools.Instance.setNewSlot( this.$dragonBone , "slot" , $skin );
                                    }
        }

结果 :
