Could someone help me with this error?

Ok so i'm just trying to make a script to walk from lumbridge to different locations depending on what the user selects. In Eclipse it shows no errors but then when I run the script I get this error in the Debug.

[ERROR][08/22 02:01:53 PM]: Failed to start script [Chambo's Bot Walker PRO]

If someone could help me solve this that would be awesome! Thanks!

Not sure where you've gotten this from; but onStart(Runnable runnable) isn't defined in script, and doesn't seem to be called at all. So your init stuff is never executed.

That's a problem; tho I don't really know why the exception indicates the lack of a parameter-less constructor

So what would I need to do to fix this error? Just replace the

public void onStart(Runnable initSettings) {

with

public void onStart() {

?

Yes, if you do that, you will be overriding the onStart method from the Script class. This overridden method will be invoked by the script executor on script start.

I removed it and i'm still getting the same error as before?

The class must be public in order for the Script Executor to access the default constructor. Add the public keyword to the class signature

Alright so the Script actually starts up now but now it freezes the client and gives me another error. And my combobox won't show up in the GUI either.

Alright so the Script actually starts up now but now it freezes the client and gives me another error. And my combobox won't show up in the GUI either.

And the current source:

You're passing null to the invokeLater method, since initSettings returns null as a runnable.

Just create a new runnable that invokes initSettings.

eg.

public void onStart() {

EventQueue.invokeLater(() -> initSettings());

}

^ using a lambda expression, so make sure you're on source 8
