I downgraded Unity too and all the errors are kinda gone but flowchart is still empty ;--;
Yikes. "kinda gone" is probably the reason tho - if there's even a single "red" error on startup, the flowcharts are wont to be empty. Also, if you upgrade Unity you should also upgrade Fungus - although there's been (as you can see in the threads here) some problems with the latest (2019) version of Unity and Fungus :) Step 1 is -> Delete the entire Assets/Fungus folder, and then redownload the version you were using from the github site (https://github.com/snozbot/fungus/releases) and import it.
Thanks for the response, wasn't expecting it. I have latest Unity 2019 and 2018.1.6 in unity hub. I already upgraded Fungus in Unity 2019...I can try re downloading the version I was using in 2018 but I don't understand the reason. In the backup folder which got all files correct there is already the fungus I used then when its not getting my flowchart :/ Still I could try redownloaing if I knew the version of Fungus Obviously I don't remember :(
Okay I downloaded it again but no change its still empty :/ My Object references are empty too. I can't figure out anything anymore.
So are there any errors still? Could you copy-paste them?
As wolfrug said, and Red errors when the game is loading can cause Fungus to not load.
I am willing to do everything again :p Got back into 2018.1 with my backup. Fixed all the object references and started working in old fungus but I am so unlucky. Even fungus is not working in my backup file. There are no errors just the say command is empty. Say command is not working, I cheked if I missed a reference or not but I can't find my mistake. Any idea about this sir? Everything is fine now in my back up file... I am willing to write the story again but for that say command needs to work man.
