Can't get OpenLevel to work

Development Programming & Scripting

Hello all

A newbee posting his first question so please be gentle :slight_smile:

I’m following the [UMG UI Designer Quick Start Guide][1], but having trouble getting OpenLevel to work.

I have a main menu (widget) with an option to start a new game. In the EventGraph, I have this:

47232-openlevelpng.png891×178 31 KB

The problem is that the level won’t open!

In the Output Log, I’ve got this two warnings:

LogActor:Warning: GameSession
/Game/FirstPersonBP/Maps/WEDPIE_0_FirstPersonExampleMap.FirstPersionExampleMap:PersistentLevel.GameSession_19
has natively added scene component(s),
but none of them were set as the
actor’s RootCoponent - picking one
arbitrarily

and

LogActor:Warning: GameNetworkManager
/Game/FirstPersonBP/Maps/WEDPIE_0_FirstPersonExampleMap.FirstPersonExampleMap:PersistentLevel.GameNetworkManager_19
has natively added scene component(s),
but none of them were set as the
actor’s RootComponent - picking one
arbitrarily

I suspect these warnings has something to do with why OpenLeven won’t work, but what do the actually mean and how to I solve it?

don’t have much time to reply right now but first I’d say start the game… on any other map, then press ~ and type open mapname (the map you think is giving you problems)

also in your charBP, create an input and wire it to open map. Then go to a map and press that button and see if the map loads there, if it opens ok there, then there probably isn’t an issue with your map.

Do you still have the issue? I guess mine is close to yours : https://answers.unrealengine.com/questions/245709/cant-get-openlevel-to-work.html

I had the same problem, I created a new Maps folder in the Content folder and dragged all my maps into that folder to re-organize things a bit, I had different maps for basic logo display and game menu option sequences with UMG widgets, and the maps/levels would open fine in the editor when played, but would not open in the mobile version because it wasn’t finding the maps by name, using the console commands wouldn’t work to manually open the maps/levels either, the fix was to place all maps directly into the Content folder only, and then it works.

You may also need to fix your paths in the DefaultEditor.ini and perform the adb logcat check for Android as is discussed here:

Another issue that comes up is if you Launch to Android and have a map other than your first one loaded before launching, the map loaded to your Android device will be the map currently loaded in the editor, so if you wanted to load for instance UE4Logo and had your Level1 loaded, it will be on Level1 already bypassing the UE4Logo if you open the levels in series in a sequence such as by level script, per level script, per map.
