Bug - Launching game on a device uses old code

Development Programming & Scripting Blueprint

Afternoon all,

I’m currently developing a game for the ios platform and there is a problem when i change something in blueprints and launch the game on the smartphone using the editor.
It is currently not updating the code and is using old that doesn’t exist. However while testing on the editor the code is in perfect shape.

Hey LuLima,

When you’re modifying your blueprint, are you compiling and saving before closing the blueprint? If so, are you also using the ‘save all’ function? Are you using the engine from the Epic Games Launcher or GitHub? Are you still on version 4.8, if so, is it 4.8.3?

Thanks!

I always compile and save before closing the blueprint editor. The save all option i don’t use because i save each one manually before closing each editor.
I’m using the one from epic games launcher, so its the 4.8.3

Would it be possible for you to create a copy of your project for 4.9 and see if it reacts the same way when you launch onto your device numerous times? It sounds as though the temporary files are not being deleted from your device.

Do you close the game out completely once you’ve finished testing it? Would you mind providing us the output from your launch?

Looking forward to hearing back from you, thanks!

Sure, to whom can i send it out to?
Yes i do close it completely. I’m running it on a ipad, i double tap the home button and close the process down.

Alright, i’ll try to replicate the issue since i just repackaged everything to update my code.
As soon as it happens again i’ll upload it to you then.

Just a quick question, packaging the project and launching it on the same device generates a complete build right?

Packaging a project through the Project Launcher allows you to select for the packaging process to build your project. Therefore, once you deployed and launched your packaged project on your device, you’d have the complete build ready to play. If you use the File > Package Project option, this too builds your project for Shipping, Development or Debugging.

I haven’t had the to try building it out on the 4.9 engine version yet. Unfortunately i’m under a heavy workload at work and haven’t had time to work on the project itself.

Please update this post when you’ve tested it in 4.9. Thank you!
