[Resolved] [C#] Hidden Incident Messages?

[jecrell]

I'd like to have a hidden raid that will surprise the player. How can I go about having a raid occur without an incident message?

[skullywag]

Just fire the incident worker but dont call the method that sends the letter.

See here for an older example but it should be somewhat valid:

You're right. However, I want to do it with a raid. So, I inherited the IncidentWorker_Raid for my class. That one doesn't seem to be possible to clear the letter being sent to players.

What should I do?

[skullywag]

well my first thought is copy the base class into another custom class, remove the letter line, set your incident to use it as its base and done. Dont know if theres any other dependencies in there, this is usually where the rabbit holes start lol.

TryExecute can be overridden. 

I would override it by copying its code from ILSpy then remove the ReceiveLetter command or alter it to your liking.

Thanks guys. As skullywag suggested, I copied a lot of the base class over and made a lot of fine tuning. Here's the solution I arrived at.

I can't tell you guys how happy I am that this worked out. I'll have to show you in the update.
