100% Crash for gui particlefx (DEF-3048)

Bugs
#1

Found out (the hard way) that if making a gui particlefx node a child to a gui spine bone node (runtime of course) and starting the particlefx, it crashes every time.
When doing it with any other node it works fine.

Hello,

I’m not able to repro this over here. I have a gui scene with a single pfx and a single spine scene. In runtime with the spine animation playing, I parent the pfx node under a spine bone node and then start the pfx. It looks like you would expect.

Do you have another setup? A sample scene with issue reproduced would help a lot :slight_smile:

/Johan

Ok I will try. I am setting up another bug right now for you (read another thread :slight_smile: ) but will try to simplify the situation I have here in the project.

You are now invited to project 84602 (Particle Gui Crash).
Also I invited you to project 78789 (Spine GUI Backward bug)

Feel free to invite Defold members if needed.

Thanks, added ticket DEF-3048 for this.

#6

Any direct understanding of what is the cause (so I might avoid it at this point)?

#7

So far I have only verified that it indeed crashes in your sample project, but not in the simple setup I created earlier. It may be some bug in batched rendering of gui nodes but I have to spend some more time digging into it to find any workaround unfortunately.

A fix for this is currently under review, hopefully it will be in the next stable release in early January.
