A question about virtual methods.

[Pikachumanson]

I am making a character generator for school. What I have to do is make my CalcPoints method abstract. Unfortunately I keep getting These three error for each of my derived character classes and I don't know what to do.

C:\Users\Hector Rosario\Documents\Visual Studio 2008\Projects\Rosario_Week3\ConsoleApplication2\Program.cs(126,26): error CS0115: 'UltimateWarrior.CalcPoints()': no suitable method found to override

C:\Users\Hector Rosario\Documents\Visual Studio 2008\Projects\Rosario_Week3\ConsoleApplication2\Program.cs(137,26): error CS0115: 'KarateWizard.CalcPoints()': no suitable method found to override

C:\Users\Hector Rosario\Documents\Visual Studio 2008\Projects\Rosario_Week3\ConsoleApplication2\Program.cs(152,26): error CS0115: 'Dragoon.CalcPoints()': no suitable method found to override

I've working on this for two days and I think I am close but I can't figure out what I am doing wrong. Any help or advice would be awesome, Thanx

Those three classes are not child classes so you do not need to override.

Looking at the code below, you are returning something?

virtual public void CalcPoints(int intMin, int intMax)
{
//Create a new instance of the class Random
Random randomNumber = new Random();
//Generate a random number using intMin as the minimum and intMax as the maximum
return randomNumber.Next(intMin, intMax);
}

function calcpoints that u have made virtual is having two parameters in its para.. list however to override that func u need to give same signature as that of ur virtual function that is with 2 para.. the overriding fn that u have made has no arguments so the compiler searches for a fn in the base class of calcpoint fn with no argiments to override.

[LizR]

Shouldnt you really have a class basis for your warrior, wizard etc so you dont have to redo half the same code? (that way you would have stuff you could override)

CalcPoints is a routine under your app not under a class, so you wont be able to override it

PS please use code tags next time it makes it easier to read

[Pikachumanson]

That is what I am trying to do. My assignment is to make the Calcpoints method abstract and I want to know how I can access it from my child class Ultimate Warrior, Dragoon and KarateWizard. By the I have have redone my code and put them in their own cs files as a class with : Charclass denote that as a base class. But yeah, Calcpoints is the of my problem right not now.

[LizR]

Well calcpoints would need to be in the base class, then it should be accessible
