[STUCK] NEED HELP - Unreal engine problem when i reload my game!

Unreal Courses Ask
#1

Hello every body,

Got a big problem with my projects since the begining i learn unreal and c++.
When i close my unreal window, and i reopen it later (maybe a few day later), my game doesnt work anymore… even if i compiled correctly and saved. It does that for all my projects (almost 8 now) actually i reopend the FPS project at the end of the course https://www.gamedev.tv/courses/enrolled/1638644 , that was working perfectly even yesterday, and i didnt touch it anymore since yesterday… and i would open it to show it to my friend, but when i opened it, the AI is broken, they go straight til my coords and they stop their run, thats all, instead of shooting me and following me…

Have you seen the Live Coding issues lecture. You need to build with Unreal closed before you re-open it if you used Live Coding. If you’re already doing that you’re probably using the wrong task, be sure to use the editor version.

If you’re still having problems please show the output of running the task.

Dan,

Thank you for the answer, the teacher (Sam) didn’t explain that we had to compile each time we need to open it on Unreal.

My build was the right (developer and editor) but i needed to rebuild it, but shal i really need to build it from visual code each time i want to open it again ?

Not every time, only if you used Live Coding. Is suggest building when you close Unreal.

That the navmesh needs to be rebuilt as you’ve likely changed the scene making the previously built navmesh to be incorrect. You can build it from the Build menu in Unreal and use build paths
