Hello, Newbie here in need of some help.
I'm getting this very long error in unity as soon as my conversation would start:

unfortunately I found nothing about it on google, does anybody have a clue about whats going on and how to fix it? As far as I understand some dialogue system functions / methods are having a conflict with other DS functions, but how could that possibly occur? As I said, I'm a beginner.

thanks in advance and best regards

Hi,

From the dropdown, choose the second instance of whatever method you're assigning, which is under the Static Parameters section:


(The screenshot above is just one example; your menu may vary.)

When you choose a method from the Dynamic Transform section, Unity will always try to pass a Transform parameter to the method. If you've chosen a method that doesn't accept a Transform, it will throw an error.

If you choose the Static Parameters one, you can point it to anything. (That is, unless the method really does accept a Transform, and really do you want the player's Transform. In that case, select the dynamic one.)

If that doesn't fix it for you, please post a screenshot of that section of the Dialogue System Events component. Also include a screenshot of what you've assigned to the OnConversationStart event. If you've assigned a script that you can open, please post the relevant method in the script.

ARRGHHHHHH huge facepalm ...
I had my assets ported to a backup version of my game and forgot that my player had a dialogue system events component assigned to it. The events in there were redundant anyways and should have been removed much earlier. They broke (lost all of their connections) when I imported the prefab to my new game version. Thats what caused the errors in the end. Gosh I feel stupid now

Thanks alot for the quick and detailed help! I hope this will also help other people who might stumble across this thread

Glad to help! Thanks for including your solution.
