Unity Spine 换图(通过外部图片)

在spine中，如果想通过外部一张单独的来替换动画中的某个部位，需要手动创建Attachment

using UnityEngine;using System.Collections;using Spine.Unity;public class ChangeSkin : MonoBehaviour {private SkeletonAnimation anim;public Texture2D t;public Texture2D t2;// Use this for initializationIEnumerator Start () {anim = GetComponent<SkeletonAnimation>();yield return new WaitForSeconds(0.2f);Material m = CreateMeshAttachmentByTexture(anim.skeleton.FindSlot("body"),t2);//换下一张图片，如果是动态加载的图片，需要消除之前的DestroyImmediate(m.mainTexture,false);m.mainTexture = t;}/// <summary>/// Creates the region attachment by texture./// </summary>/// <returns>The region attachment by texture.</returns>/// <param name="slot">Slot.</param>/// <param name="texture">Texture.</param>public Material CreateRegionAttachmentByTexture(Spine.Slot slot, Texture2D texture){if(slot==null) return null;Spine.RegionAttachment oldAtt = slot.Attachment as Spine.RegionAttachment;if(oldAtt==null || texture==null) return null;Spine.RegionAttachment att = new Spine.RegionAttachment(oldAtt.Name);att.RendererObject = CreateRegion(texture);att.Width = oldAtt.Width;att.Height = oldAtt.Height;att.offset = oldAtt.offset;att.Path = oldAtt.Path;att.X = oldAtt.X;att.y = oldAtt.Y;att.Rotation = oldAtt.Rotation;att.ScaleX = oldAtt.ScaleX;att.ScaleY = oldAtt.ScaleY;att.SetUVs(0f,1f,1f,0f,false);Material mat = new Material(Shader.Find("Sprites/Default"));mat.mainTexture = texture;(att.RendererObject as Spine.AtlasRegion).page.rendererObject = mat;slot.Attachment = att;return mat;}/// <summary>/// Creates the mesh attachment by texture./// </summary>/// <returns>The mesh attachment by texture.</returns>/// <param name="slot">Slot.</param>/// <param name="texture">Texture.</param>public Material CreateMeshAttachmentByTexture(Spine.Slot slot, Texture2D texture){if(slot==null) return null;Spine.MeshAttachment oldAtt = slot.Attachment as Spine.MeshAttachment;if(oldAtt==null || texture==null) return null;Spine.MeshAttachment att = new Spine.MeshAttachment(oldAtt.Name);att.RendererObject = CreateRegion(texture);att.Path = oldAtt.Path;att.Bones = oldAtt.Bones;att.Edges = oldAtt.Edges;att.Triangles = oldAtt.triangles;att.Vertices = oldAtt.Vertices;att.WorldVerticesLength = oldAtt.WorldVerticesLength;att.HullLength = oldAtt.HullLength;att.RegionRotate = false;att.RegionU = 0f;att.RegionV = 1f;att.RegionU2 = 1f;att.RegionV2 = 0f;att.RegionUVs = oldAtt.RegionUVs;att.UpdateUVs();Material mat = new Material(Shader.Find("Sprites/Default"));mat.mainTexture = texture;(att.RendererObject as Spine.AtlasRegion).page.rendererObject = mat;slot.Attachment = att;return mat;}private Spine.AtlasRegion CreateRegion(Texture2D texture){Spine.AtlasRegion region = new Spine.AtlasRegion();region.width = texture.width;region.height = texture.height;region.originalWidth = texture.width;region.originalHeight = texture.height;region.rotate = false;region.page = new Spine.AtlasPage();region.page.name = texture.name;region.page.width = texture.width;region.page.height = texture.height;region.page.uWrap = Spine.TextureWrap.ClampToEdge;region.page.vWrap = Spine.TextureWrap.ClampToEdge;return region;}}
