Memory Leak in FireFly ?

**defisym** · 7th May 2019, 02:29 PM

I found this issue by accident.
leak.mfa
The example .MFA is based on firefly example : Basics - Splitscreen.
Application.jpg
Add a new event :

Code:

* timer > 2000
	storyboard controls : Restart the application

Sometimes people use this action to start a new game.
Build the application (sorry but the .exe exceeds the limitation of .zip file size) and run it, then look into task manager :
First run : about 20MB

After restart several times : more than 110MB

I have tried the same thing in a traditional 2D game without firefly , but did't notice any leak.
So is this a bug, or there is something wrong with my settings?

I'm having the same problem. I even tried to destroy every object and remove every material from the cache object stop the firefly engine and then destroy it but it stills chews 150 mb of RAM and is increased every time I restart the frame or application. No idea what's causing it :-/

I think it might because they forget to release some of allocated memory in DestroyRunObject() routine (like other extensions)...
As we all know, 3D engine is much more complicated

Weird thing is that I made a second frame, added a firefly engine, a camera and the character and did an event to stop the engine and destroy everything and then restart the frame...then I had no memory increase....I don't know what's going on there

I think the leak is mainly due to FireFly 2D Text Object, I still got a leak even I stop the engine and destroy everything. if remove it from the frame, although memory usage is still growing, but this time it grows very slow, about 0.1MB~0.3MB per restart.I think I can safely ignore it if grows in this rate.
But......if you don't destroy everything you got, you still can see the leak, whether there is a 2D Text in frame or not.
