Scene Portal

[Chuc]

Not 100% where to ask this question. I got the scene portal when I got Quest Machine so i thought here was a good spot.

I am using UFPS, UIS and Quest Machine. I haven't made any quest yet or done any set up for Quest Machine atm as i am trying to get game working half decent before i flesh it out. The save system between the 3 is driving me nuts but that isn't what i am here for yet.

I have a starter scene where the game loads all my systems, then you travel to another scene but you end up being in the same position from the old scene in the new scene. Scene portal was suppose to fix this issue but i am having trouble with it. It is not sending me to the game object location of the new scene.

if i move the starter scene location over the spot of the second scene it loads fine, inventory works and all the UIS things work.

Hi,

The ScenePortal component is part of the save system, so you'll want to make sure the save system is set up. The easiest way to do that is to:

1. Download the SaveSystemPrefabs package and import it.
2. Drop the Save System prefab into your systems scene.
3. Add the LoadingScreen scene to your build settings. (You can customize it later.)
4. Make sure no other instances of the SaveSystem component are present, such as on your Quest Machine GameObject.

Alternatively, you can add the save system components (SaveSystem, [Json]DataSerializer, [PlayerPrefs]SavedGameDataStorer) to another GameObject such as the Quest Machine GameObject. The key is that only one SaveSystem component exists in the scene. (In used [square brackets] because it's fine to add different variations such as DiskSavedGameDataStorer instead of PlayerPrefsSavedGameDataStorer.)

Since you're using UFPS, don't add a PositionSaver component to your player. Instead, add a UCCSaver. Assign a unique key such as "PlayerData" and make sure the Save Position checkbox is ticked. Also make sure this GameObject is tagged "Player".

That should do it. If you see any errors or warnings after changing scenes using the Scene Portal, let me know.

So i added a UCC Saver to the player and it worked but my inventory from UIS didnt save so i added a UIS Saver to the player. That got my inventory to save and all work good but i got this error

If i remove the UIS Saver the error goes away but my inventory doesnt save. I am missing something somewhere or is UIS Saver the wrong one to use?

Hi,

The error is in UIS. Please try backing up your project and updating to the latest UIS version. If that doesn't fix it, send this information to Opsive on their forum or discord server:
