cocos教程：DragonBones骨骼动画资源

龙骨动画

将龙骨动画放到cocos的assets下。我这里龙骨动画是Dragonbones导出的二进制动画。

直接拖拽龙骨动画(骨头图标)到舞台

设置骨骼动画的属性，Dragon Altas Asset图片，Animation动作，PlayTime循环播放等

代码生成龙骨动画

龙骨资源路径是assets/resources/dragonbones，loadResDir只需要填dragonbones就行了。

//根据路径加载资源
cc.loader.loadResDir("dragonbones",cc.Asset,null,(err, resource)=>{
            console.log("资源：",resource);
            //生成骨骼动画
            let node:cc.Node = new cc.Node();
            let armatureDisplay:dragonBones.ArmatureDisplay = node.addComponent(dragonBones.ArmatureDisplay);
            armatureDisplay.dragonAsset = resource[0];
            armatureDisplay.dragonAtlasAsset = resource[3];
            armatureDisplay.armatureName = "role3";
            armatureDisplay.playAnimation("move",0);
            node.x = 100;
            node.y = 100;
            this.node.addChild(node);
        });

动画2替换动画1皮肤

        //加载资源
         cc.loader.loadResDir("dragonbones",cc.Asset,null,(err, resource)=>{
             console.log("资源：",resource);

            //生成动画1
            let node:cc.Node = new cc.Node();
            let armatureDisplay:dragonBones.ArmatureDisplay = node.addComponent(dragonBones.ArmatureDisplay);
            armatureDisplay.dragonAsset = resource[0];
            armatureDisplay.dragonAtlasAsset = resource[3];
            armatureDisplay.armatureName = "role3";
            armatureDisplay.playAnimation("move",0);
            node.x = 100;
            node.y = 100;
            this.node.addChild(node);

            //生成动画2
            let node2:cc.Node = new cc.Node();
            let armatureDisplay2:dragonBones.ArmatureDisplay = node2.addComponent(dragonBones.ArmatureDisplay);
            armatureDisplay2.dragonAsset = resource[4];
            armatureDisplay2.dragonAtlasAsset = resource[7];
            armatureDisplay2.armatureName = "role4";
            armatureDisplay2.playAnimation("move",0);
            node2.x = 150;
            node2.y = 150;
            this.node.addChild(node2);
            

            //动画2的皮肤应用到动画1上
            let factory = dragonBones.CCFactory.getInstance();
            factory.replaceSkin(armatureDisplay.armature(), (armatureDisplay2.armature() as dragonBones.Armature).armatureData.defaultSkin, true);
        });
