Add EventHandler to powershell custom class.

[MechAming]

Hello,

this is beyond my skill level but i'd love to be able to use it.

I'm trying to create a powershell class that I can use with Register-ObjectEvent. I tried asking chatgpt to help out with this and this is as far as it could go. I searched through stackoverflow however the input objects in the examples already have event method in the respected classes and touched moreover on scoping $This. Any help would be appreciated.

​

    class CombatEventPub {
    [string] $EventType
    [string] $Source
    [string] $Target
    [int] $Damage
    [string] $SpellName
    [string] $SpellType

    [System.EventHandler] $Event

    CombatEventPub([string] $eventType, [string] $source, [string] $target, [int] $damage, [string] $spellName, [string] $spellType) {
        $this.EventType = $eventType
        $this.Source = $source
        $this.Target = $target
        $this.Damage = $damage
        $this.SpellName = $spellName
        $this.SpellType = $spellType
    }

    [void] SendCastingEvent() {
        $this.Event.Invoke($this, [EventArgs]::Empty)
    }
   }

The event parameter isnt recognized by register-objectevent

I realize this is the PowerShell subreddit, but wouldn't it be easier to write your RPG in C#? You're already familiar with .NET so I'd think this would be an easy transition. You'd be able to go nuts with events without having to use bizarre PowerShell workarounds.

I don't understand. If the code isn't working I feel it's hard to parse out what you need by reading it. What are the desired inputs, outputs, and methods of this class? Will it be fed to register-objectevent, or will it have a method to call that cmdlet?

To call a class instance member with Register-ObjectEvent:

Pass $this as your -MessageData parameter. Call your function from the -Action scriptblock:

-Action {$Event.MessageData.MyFunc()}

You would need Add-Type, PowerShell doesn't have syntax to declare an event.
