spine动画插入任意Actor

spine中插入任意Actor

原理替换到data数据中的region

修改部分

Skin

add set region方法
public void setAttachment(Attachment attachment) {
  this.attachment = attachment;
}

获取data数据，设置region

SkeletonData data = actor.getSkeleton().getData();
Skin defaultSkin = data.getDefaultSkin();
for (Skin.SkinEntry attachment : defaultSkin.getAttachments()) {
    if (attachment.getName().equals("xuanq2_00")) {
        attachment.setAttachment(actorAttachment);
    }
}

修改renderer方法

draw方法加入
if (attachment instanceof ActorAttachment){
    Actor actor = ((ActorAttachment) attachment).getActor();
    Bone bone = slot.getBone();
    float worldX = bone.getWorldX();
    float worldY = bone.getWorldY();
    actor.setOrigin(Align.center);
    actor.setPosition(worldX,worldY, Align.center);
    actor.setScale(bone.scaleX,bone.scaleY);
    actor.setColor(slot.getColor());
    actor.draw(batch,skeleton.color.a);
}

自定义ActorAttachment

import com.badlogic.gdx.scenes.scene2d.Actor;

public class ActorAttachment extends Attachment {

    private Actor actor;

    public ActorAttachment(String name) {
        super(name);
    }

    public Actor getActor() {
        return actor;
    }

    public ActorAttachment(ActorAttachment actorAttachment) {
        super(actorAttachment);
        this.actor = actorAttachment.actor;
    }

    public void setActor(Actor actor) {
        this.actor = actor;
    }

    @Override
    public Attachment copy() {
        return new ActorAttachment(this);
    }
}

理论上可以支持任意……
