Spine 如何换装? 目前实现了多套皮肤打在一起的方式

Cocos2d-x
#1

目前只够定了 不同套皮肤打在一个文件里的方式, 例如: 可以给只更换某个武器. 但是如果需要更换的皮肤特别多的话. 就会给内存带来压力. 求教如何加载一个外部的一个png图片更换.
网上有人实现了类似的, 原文地址:http://blog.csdn.net/n5/article/details/21795265
但是这个有一个致命问题就是无法设置新添加部件的层级. 只能在最后或者最前.
spine换装的需求应该很强烈吧. 但网上很少有类似的资料.

帮你顶一下啊，

把当前hero remove
在相同 的position重新create

顶。。。。

目前spine没有提供换装的方法，需要自己去修改spine的源码来实现。之前的一个项目中有这方面的需求，试着实现了一下。方法直接加在类SkeletonRenderer中。

bool SkeletonRenderer::changeAttachment(const std::string& slotName, const std::string& attachmentName, const std::string& atlasFile)
{
spSlot * slot = this->findSlot(slotName);
if (NULL == slot)
{
return false;
}

int nType = slot->attachment->type;
spAtlas* atlas = createSpAtlasFromFile(atlasFile.c_str(), 0);
CCASSERT(atlas, "SkeletonRenderer::changeAttachment Error reading atlas file");

spAtlasAttachmentLoader* atlasAttachMentLoader = spAtlasAttachmentLoader_create(atlas);
spAttachmentLoader *attachmentLoader = &(atlasAttachMentLoader->super);

spSkin *skin = spSkin_create("default");
switch (nType)
{
case SP_ATTACHMENT_REGION:
    {
        spRegionAttachment* regionAttachmentSrc = (spRegionAttachment*)(slot->attachment);
        spAttachment* attachment = spAttachmentLoader_newAttachment(
            attachmentLoader, skin, SP_ATTACHMENT_REGION, slotName.c_str(), attachmentName.c_str());
        //spAttachment* attachment = spAttachmentLoader_newAttachment(attachmentLoader, NULL, SP_ATTACHMENT_REGION, "role_weapon", "weapon_104005");
        spRegionAttachment* regionAttachment = (spRegionAttachment*)attachment;
        regionAttachment->width = regionAttachmentSrc->width;
        regionAttachment->height = regionAttachmentSrc->height;
        regionAttachment->rotation = regionAttachmentSrc->rotation;
        regionAttachment->x = regionAttachmentSrc->x;
        regionAttachment->y = regionAttachmentSrc->y;
        regionAttachment->scaleX = regionAttachmentSrc->scaleX;
        regionAttachment->scaleY = regionAttachmentSrc->scaleY;
        regionAttachment->a = regionAttachmentSrc->a;
        regionAttachment->b = regionAttachmentSrc->b;
        regionAttachment->r = regionAttachmentSrc->r;
        regionAttachment->g = regionAttachmentSrc->g;

        spRegionAttachment_updateOffset(regionAttachment);
        slot->attachment = (spAttachment*)regionAttachment;
    }
    break;
case SP_ATTACHMENT_BOUNDING_BOX:
    {
        spBoundingBoxAttachment* boxAttachmentSrc = (spBoundingBoxAttachment*)(slot->attachment);
        spAttachment* attachment = spAttachmentLoader_newAttachment(
            attachmentLoader, skin, SP_ATTACHMENT_REGION, slotName.c_str(), attachmentName.c_str());
        spBoundingBoxAttachment* boxAttachment = (spBoundingBoxAttachment*)attachment;
        boxAttachment->verticesCount = boxAttachmentSrc->verticesCount;
        boxAttachment->vertices = boxAttachmentSrc->vertices;
        for (int i = 0; i < boxAttachmentSrc->verticesCount; i++)
            boxAttachment->vertices* =boxAttachmentSrc->vertices*;
        slot->attachment = (spAttachment*)boxAttachment;
    }
    break;
case SP_ATTACHMENT_MESH:
    {
        spMeshAttachment* meshAttachmentSrc = (spMeshAttachment*)(slot->attachment);
        spAttachment* attachment = spAttachmentLoader_newAttachment(
            attachmentLoader, skin, SP_ATTACHMENT_REGION, slotName.c_str(), attachmentName.c_str());
        spMeshAttachment* meshAttachment = (spMeshAttachment*)attachment;
        meshAttachment->rendererObject = meshAttachmentSrc->rendererObject;
        meshAttachment->regionU = meshAttachmentSrc->regionU;
        meshAttachment->regionV = meshAttachmentSrc->regionV;
        meshAttachment->regionU2 = meshAttachmentSrc->regionU2;

        meshAttachment->regionHeight = meshAttachmentSrc->regionHeight;
        meshAttachment->regionOriginalWidth = meshAttachmentSrc->regionOriginalWidth;
        meshAttachment->regionOriginalHeight = meshAttachmentSrc->regionOriginalHeight;

        spMeshAttachment_updateUVs(meshAttachment);
        slot->attachment = (spAttachment*)meshAttachment;
    }
    break;
case SP_ATTACHMENT_SKINNED_MESH:
    {
        spSkinnedMeshAttachment* skinnedAttachmentSrc = (spSkinnedMeshAttachment*)(slot->attachment);
        spAttachment* attachment = spAttachmentLoader_newAttachment(
            attachmentLoader, skin, SP_ATTACHMENT_REGION, slotName.c_str(), attachmentName.c_str());
        spSkinnedMeshAttachment* skinnedAttachment = (spSkinnedMeshAttachment*)attachment;
        skinnedAttachment->rendererObject = skinnedAttachmentSrc->rendererObject;
        skinnedAttachment->regionU = skinnedAttachmentSrc->regionU;
        skinnedAttachment->regionV = skinnedAttachmentSrc->regionV;
        skinnedAttachment->regionU2 = skinnedAttachmentSrc->regionU2;
        skinnedAttachment->regionV2 = skinnedAttachmentSrc->regionV2;
        skinnedAttachment->regionRotate = skinnedAttachmentSrc->regionRotate;

    }
    break;

return true;

这个在setAnimation后 换装就无效了。你那有做什么特殊操作吗？

#14

试试 可能能用
