dom452 commented 3 years ago

Getting strange crash when closing PIE Same project also correctly works in PIE, but does not work when built.

Editor crash report reads:

thoughts?

I've added a common sense condition to that bit of code. That should prevent the crash. Be sure to delete your intermediates / binaries folders after downloading, to rebuild from latest source.

I, I see! Got a type mismatch on that line (468) - so changed it to ..."< uint_fast32_t (Octree.Leafs.Num()))" and it built successfully - was that the right move? Asking cos when I tested it - it popped the below and crashed on exiting PIE and don't know if it's my fault?

really appreciate your time, btw. This plugin is awesome and we'll have to figure out some usage rights thing at some point!

darbycostello commented 3 years ago

That's what I get for editing directly in Github without testing. I'll pull it up later but essentially yes, I probably needed to static cast that array count. There are no usage rights for this plugin, everything I put up here is GPL, so fill your boots. My commercial work is not public.

Fixed! TY!
