Cannot Assign To A Null Value

[Timeslip]

Hi Tony,

Is this the result of deleting a variable in the database? Using easy save 3 as the save system. If so, is there a way to tell what the missing variable is, or a workaround?

Code: Select all

Hi,

No, you can delete variables. Did you delete a conversation that had ID 26 perhaps? (That should be fine, but I'm trying to narrow down the possibilities from the snippet you provided.)

[Timeslip]

I've restored the entire debug info. I did delete a conversation or two over the weekend.

[Tony Li]

That may be a bug. I'll investigate and reply back today.

[Timeslip]

Thanks. I should let you know that it's an older version (2.1.8) with some custom scripts you sent. If you think updating will resolve, happy to do so.

[Tony Li]

I confirmed that it's a bug with SimStatus and deleted conversations. I'll post a patch here by tomorrow morning.

[Tony Li]

Hi,

Here's the patch:

DS_SimStatusSaveLoadPatch_2020-11-02.unitypackage

It will be in the next Dialogue System release, too.

To install the patch:

1. Back up your project.
2. Import the patch.
3. If there are any compile errors, update to DS version 2.2.12, then reimport the patch.

Hi Tony,

Thanks, and apologies for the delay in getting back to you. The patch appears to have worked. I say appears because there is a separate issue with the save data which is preventing loading at present, but the original issue is no longer throwing any errors.

[Tony Li]

Glad to help! The new version 2.2.13, with the same update as in the patch, is now live on the Asset Store, too.
