Using a function from a different class

[bixel]

2008 C# Forms

I have extended class called, LevelChanger : NumericUpDown, and have added a function called ChangeLevel

The Class, and the Function I will be using

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace Battler
{
    class LevelChanger: NumericUpDown
    {
        private decimal levelNumber;

        public Battler battler = new Battler();

        public decimal LevelNumber
        {
            get { return levelNumber; }
            set { levelNumber = value; }
        }

        private float HPrate;
        private float holderHP;
        private float holderMP;
        private int oldLevel;
        public int newStrength, newVitality, newAgility;

        private void ChangeLevel(string measure1, string measure2, string measure3)
        {
            int newValue = Convert.ToInt32(LevelNumber);
            int oldStrength = Convert.ToInt32(measure1);
            int oldVitality = Convert.ToInt32(measure2);
            int oldAgility = Convert.ToInt32(measure3);
            if (newValue == 0)
            {
                holderHP = 100f;
                holderMP = 0f;
            }
            else if (newValue > 0)
            {
                float newHitPoints;
                float newMagicPoints;
                if (6 > newValue)
                {
                    HPrate = 1.25f;
                }
                else if (5 < newValue && newValue < 11)
                {
                    HPrate = 1.20f;
                }
                else if (10 < newValue && newValue < 16)
                {
                    HPrate = 1.15f;
                }
                else if (15 < newValue && newValue < 21)
                {
                    HPrate = 1.10f;
                }
                else if (20 < newValue && newValue < 31)
                {
                    HPrate = 1.05f;
                }
                else if (30 < newValue && newValue < 41)
                {
                    HPrate = 1.02f;
                }
                if (newValue > oldLevel)
                {
                    newHitPoints = (holderHP + battler.CheckClassHPMod()) * HPrate;
                    newMagicPoints = (holderMP + battler.CheckClassMPMod());
                    // new stats
                    newStrength = oldStrength + battler.CheckClassStrMod();
                    newVitality = oldVitality + battler.CheckClassVitMod();
                    newAgility = oldAgility + battler.CheckClassAglMod();
                }
                else
                {
                    newHitPoints = (holderHP - battler.CheckClassHPMod()) / HPrate;
                    newMagicPoints = (holderMP - battler.CheckClassMPMod());
                    // new stats
                    newStrength = oldStrength - battler.CheckClassStrMod();
                    newVitality = oldVitality - battler.CheckClassVitMod();
                    newAgility = oldAgility - battler.CheckClassAglMod();
                }
                //convert to Int to get rid of decimal value.
                int adjustedMagicPoints = Convert.ToInt32(newMagicPoints);
                int adjustedHitPoints = Convert.ToInt32(newHitPoints);
                holderHP = adjustedHitPoints;
                holderMP = adjustedMagicPoints;
            }
            oldLevel = newValue;
        }
    }
}

in my main.cs I initialize it like this

            this.levelChanger2 = new LevelChanger();

Since LevelChanger is a NumericUpDown tool I am using it in my forms. I have this event fired when its used.

        private void ChangeLevels1(object sender, EventArgs e)
        {
            //do some stuff
        }

In this event I want to fire that object's function but I can't seem to access it. Doing this
this.levelChanger2.ChangeLevel(measure1, measure2, measure3)

doesn't work. But I can access its variables. Like;
levelChanger2.newStrength = something...

Why can't I get to its function even though I already instantiated it??

Because it is a private function. If you would like it to be accessible outside of the class, mark it as 'public'. Look here for all of the access modifiers.

OH MAH GAWD. I must have been blind, hahahah I a so used to using privite stuff initially I didn't even look there.
