Disappearing attachments on 64bit iOS caused by Drawing Orde

Zsolt

Hello!

We ran into a weird issue on 64bit iOS using Cocos2d-iPhone runtime with Cocos2d 3.0. Animations with drawing order changes make some attachments to disappear. Even if there are no drawing order changes on the slots containing the disappearing attachments. As soon as I delete the drawing order keyframes everything stays, but of course with no drawing order. The same animations still work when we run the app on 32bit devices.

We tried so far to re-set the drawing order keyframes, to move them around and to make new drawing orders, but nothing worked or just made even more random stuff to disappear.

Do You have an idea about what could be the source of our problem?

First, are you using the latest runtime from the official GitHub?

I don't see anything in the draw order code that stands out as being suspicious. It's using sizeof where it should. Maybe you can narrow it down further? If you comment out code in _spDrawOrderTimeline_apply does the problem go away?

Hi Nate,

We are not using the latest spine-c runtime because for some reason it is not compatible with the current spine-cocos2d-iphone runtime. The version we are using is supposedly the last version of spine-c that was still working with spine-cocos2d-iphone.

By you pointing us to the _spDrawOrderTimeline_apply method we noticed that indeed there was a fix regarding this in the spine-c runtime back in November (7b804f41979eaeda385e99d1b6bddeca8a7e5853). Applying the same fix without updating the rest of the spine-c seems to resolve the issue with the draw order on the 64 bit architecture. Thanks for that!

By the way, is there a version of spine-cocos2d-iphone that is fully compatible with the latest spine-c runtime?

Sorry, I wasn't aware the runtime was broken with the latest cocos2d-iphone. Do you know what the issue is? I will find time to look into it soon.

The changes in spine-c from the last couple of months caused the cocos2d-iphone to be incompatible (changed method headers, arguments etc.). The cocos2d-iphone needs to updated to use all the new classes and methods from spine-c, that's all.

Let me know when you manage to do that. Thanks!
