Hi All,
I am using 3.10 lib and I am trying to solve a problem about how to cache Spine Data. Right now my idea is to create a global map object as a cache, then in my new game loading screen I preload the SkeletonRenderer into this cache.
auto skeletonRenderer = SkeletonRenderer::createWithFile("spineboy/spineboy.json", "spineboy/spineboy.atlas", 1); _spineCache.insert(std::make_pair("spineboy", skeletonRenderer ));Well, 2nd step, I suppose I can create SkeletonAnimation from Skeleton data, then I try to get data from SkeletonRenderer.
auto cacheData = _spineCache.at("spineboy")->getSkeleton()->data; auto skeletonNode = SkeletonAnimation::createWithData(cacheData);Then I setAnimation, setPosition then add to my game world. when I started game, it passed loading session, started with initlial drawing, but it crashed when drawing this spine object.
After that I tried to figure out is that my map object fail to store data. I tried to not use cache, created SkeletonRenderer directly on top of SkeletonAnimation::createWithData and then ran it with the same result...
auto directRenderer = SkeletonRenderer::createWithFile("spineboy/spineboy.json", "spineboy/spineboy.atlas", 1); auto skeletonNode = SkeletonAnimation::createWithData(directRenderer->getSkeleton()->data);So, question is "Does SkeletonAnimation::createWithData(SkeletonRenderer->getSkeleton()->data) work?"
As there is no problem to draw spine if I use SkeletonAnimation::createWithFile.
auto skeletonNode = SkeletonAnimation::createWithFile("spineboy/spineboy.json", "spineboy/spineboy.atlas", 1);Finally, I found that the crash is caused by skeletonNode->setAnimation(0, "walk", true);
But it works fine if my skeletonNode is createWithFile, only failed when it is createWithData. If I remove setAnimation line it still can draw for createWithData without animation...I do appreciate your help! this problem has already held me up for a few hours.
