ArgumentOutOfRangeException when simulateMovement is set to false on top of OffMeshLink (v5.4.5)

General

As mentioned in the title when the agent is on top of an offmesh link and I call simulateMovement = false then I get this error. Is it supposed to happen? If I disable FollowerEntity there is no issue.

ArgumentOutOfRangeException: Specified argument was out of the range of valid values.

I’ll tag Aron in this exception to take a look at. Can you let us know what versions of the Entities dependency/package you have installed? Also if you’re able to edit your post with a formatted version of the exception with line breaks that would be nice as well- tried to format it as code but it didn’t work without line breaks.

I have Entities: 1.4.3 in Unity version 6000.2.10f. Sorry but I can’t find the way to format it

Np, I took the time to parse the text and reformat it. Thanks for the info!

Hi

I cannot replicate this. But I did already fix a very related bug. Possibly it was the same one.

I’ll include that fix in the next update. Let me know if it resolves the issue for you.

I have not come across the issue so far so it seems to be fixed after the latest update. Thanks a lot!
