inheritance does not work, why? - Nerus - 05-05-2012

Hi I created two example libraries.
A parent, after which the child class inherits.
Why such a solution does not work where I do wrong?

Parent:

PHP Code:
using System;
using Addon;

namespace Parent
{
    public class parent : CPlugin
    {
        public parent(string Name)
        {
            ServerPrint("Plugin " + Name + " loaded");
        }

        public override void OnPlayerSpawned(Addon.ServerClient Client)
        {
            ServerPrint("#1 Player: " + Client.Name + " spawned");
        }

    }
} 

Child:

PHP Code:
using System;
using Parent;

namespace Child
{
    public class child : parent
    {
        child() : base("Test Child Plugin")
        {

        }

        public override void OnPlayerSpawned(Addon.ServerClient Client)
        {
            ServerPrint("#2 Player: " + Client.Name + " spawned");
        }
    }
}

Does it not compile at all or does it give an error?

When I inherited Cplugin in 2 different classes I got "System.MissingMethodException" for some reason.

I use the inheritance to the two libraries, each class is a library.
I don't have errors, when delete Constructors from code, plugin work properly.
A strange thing.

Is there anything in the logs?

RE: inheritance does not work, why? - Pozzuh - 05-05-2012

That's the same exception I get.. must be a problem with the addon or something.

Crap, I had such a cool idea.

This is a problem :

for this code

PHP Code:

using Addon;

namespace TestProblem
{
    public class TestProblem : CPlugin
    {

        public TestProblem()
        {
            ServerPrint("Test Object Load !!!"); // <- this is problem, do not use CPlugin in constructor.
                                                 // Always create public constructor if You use second constructor or create instances.
        }

        public override void OnServerLoad()
        {
            base.OnServerLoad();
            ServerPrint("Start !!!");
        }
        
        
    }
} 

RE: inheritance does not work, why? - master131 - 05-06-2012

A class that inherits CPlugin cannot have an instance constructor, it's a static class. Use the friggin OnServerLoad override or define the constructor as static. Dodgy

Note that static constructors cannot accept parameters.

eg:

Code:
using System;
using Addon;

namespace TestPlugin
{
    public class Test: CPlugin
    {
        static Test()
        {
            // Do crap here.
        }
    }
}
