[FARMERRICH]

Could you post proper source code? I want to do some editing

[Diskretor]

zxz0O0, you wrote "This plugin uses signature scans to find the offsets"
But i see there are no code for that scan in the 1-st post.

I use the code below for scanning. But it seems the addresses are wrong.
Can you help to correct this, please.

Code:

namespace NoKnife
{
    using Addon;
    using System;
    using System.Runtime.InteropServices;

    public class Class1 : CPlugin
    {
        private int DefaultKnifeAddress;
        private int KnifeRange;
        private string str_Knife = "enabled";
        private bool Working = true;
        private int ZeroAddress;

        private int FindMem(byte?[] search, int num = 1, int start = 0x1000000, int end = 0x3d00000)
        {
            int num2 = 0;
            try
            {
                int num3 = 0;
                for (int i = start; i < end; i++)
                {
                    num2 = i;
                    bool flag = false;
                    for (int j = 0; j < search.Length; j++)
                    {
                        if (search[j].HasValue)
                        {
                            int num7 = num2[0];
                            if (num7 != search[j])
                            {
                                break;
                            }
                        }
                        if (j == (search.Length - 1))
                        {
                            if (num == 1)
                            {
                                flag = true;
                            }
                            else
                            {
                                num3++;
                                if (num3 == num)
                                {
                                    flag = true;
                                }
                            }
                        }
                        else
                        {
                            num2++;
                        }
                    }
                    if (flag)
                    {
                        return i;
                    }

The plugin is working AFAIK, the source code on the main post is outdated I think.
did you decompile it or what?

[Diskretor]

This code is outdated and doesn't work for me.
Yes. I trying to see the source of DLL that normally worked.
