The "Why did I get this error?" Topic

Want to know why you're getting a specific error or why an exception is being thrown?

Post the error as well as the relevant code here and I and other programmers will try to help you out as soon as possible.

Re: The "Why did I get this error?" Topic

Why I got that ? :

L'exception InvalidCastException n'a pas été gérée par le code utilisateur

Value at index:13 is not System.Int32. It's a System.String

I made that with the tutorial of jabatheblob1 4 :https://www.youtube.com/watch?v=2bK5bcGWx6E

Re: The "Why did I get this error?" Topic

Jaba's tutorials are mostly outdated I think. World width is now index 18 and height is 19. Replace 12 with 18, and 13 with 19. Also you'll probably need to replace unit kc = 17 with 39.

I'm on my phone right now and I'm about to go to work but there's probably more stuff you need to do. For example where do you check to see if the message type is "init"?

Re: The "Why did I get this error?" Topic

Could also be a world with new blocks that have special (meta?) data. Adding those

So you've made a "get help here" topic which is basically the gist of half the posts here.
Interesting choice.

Not really tbh most of the posts are bot releases and questions not related to a specific error

Are you sure that block class is set to public?

Just check if the key exists, and if it does, stop the room crawler, remove it and create a new one as you did before?

That's what I'm doing right now, except for some reason the memory is leaking, causing the crawler to occasionally get stuck and hold up the thread since there is a low-level attachment to an object in ms*.dll or something. I've tried using StrongBox and then deleting that, but it doesn't really help.

If its used cross-thread you should mark it with volatile keyword.

The code are already saying whats wrong, "An element with the same key already exists in the dictionary"
But if you want to go deeper and find exactly where, you need to run visual studio.
Do you run the bot on a VPS? I don't know a way to debug the code on a VPS. I guess you use mono.

If you use Visual Studio:

To get to the correct place there the error came from.
Click on CTRL + ALT + E, then click on "Common Language Runtime Exceptions".
Then click on "System.ArgumentException" and run the code.

Re: The "Why did I get this error?" Topic

Fun fact: I actually learned something in CS 101: the error isn't always on the line that's flagged, sometimes you have to look up.

        Dictionary<uint, object[]> is your problem.

If you don't know what you want that line to do, just remove it.

Why does so many people use "leave"? When it's "left" in the protocol and have always been "left".

Because it'd makes sense if "join" was used when a player enters.
