I have just upgraded my project to the new 2019.4.01 LTS release, but now my agents will never find a path. AIPath debug states that ‘Path Pending’ is always true. I then went on to downgrade the project back to 2019.3.0f6 and agents are back working as normal. Are there any known issues with the 2019.4 release? I am using 4.3.26.
There are no known issues with that build.
Are you seeing any errors in the console?
No errors in the console no. Have just tried a fresh project in 2019.4 using your examples, and that is working okay. Trying the examples in my current project produces the same issue- path pending and no movement.
Not sure what the issue is. Will update you if I find it as might be relevant to other people.
Okay so I had another look at this and turns out the issue is with the experimental ‘Enter Play Mode’ settings in Project Settings/Editor. If I enable ‘Reload Scene’ the pathfinding is working again. In 2019.3.0f6 I had both ‘Reload Domain’ and ‘Reload Scene’ off and had no issues, but some change in this setting in 2019.4.01 must have caused an issue.
Ah. Yeah disabling both of those do cause issues.
In the current beta the inspector will show a big warning if both “Reload Scene” and “Reload Domain” is disabled. It’s tricky to support both of them at the same time.
