Enemies location in map

[zer0byte]

Hello
In conquer online private server the versions before 3D
the X and Y Axis of player is encrypted

for examle when I located at twin city at location (330,252)
the memory values is equal X:28864 and Y:9312

how to decrypt it to get enemies entitylist real locations?

From the other threads you keep creating on this topic, it sounds like you're using a proxy. Look at private server source code... they usually have the answers you seek. Idk if this is true for the most updated version of Conquer 3.0 (not 3D), but here's how it's done in 6090 according to :

private void DecodeSkill()
        {
            SkillId = (ushort) ( ExchangeShortBits(( SkillId ^ ObjectId ^ 0x915d ), 13) + 0x14be );
            var sl = SkillLevel = ( (ushort) ( (byte) SkillLevel ^ 0x21 ) ); // fix for .net 4.6 overflow issue
            TargetObjectId = ( ExchangeLongBits(TargetObjectId, 13) ^ ObjectId ^ 0x5f2d2463 ) + 0x8b90b51a;
            PositionX = (ushort) ( ExchangeShortBits(( PositionX ^ ObjectId ^ 0x2ed6 ), 15) + 0xdd12 );
            PositionY = (ushort) ( ExchangeShortBits(( PositionY ^ ObjectId ^ 0xb99b ), 11) + 0x76de );
        }

        private void EncodeSkill()
        {
            SkillId = (ushort) ( ExchangeShortBits(ObjectId - 0x14be, 3) ^ ObjectId ^ 0x915d );
            SkillLevel = (ushort) ( ( SkillLevel + 0x100 * ( Timestamp % 0x100 ) ) ^ 0x3721 );
            Arg1 = MathUtils.BitFold32(SkillId, SkillLevel);
            TargetObjectId = ExchangeLongBits(( ( TargetObjectId - 0x8b90b51a ) ^ ObjectId ^ 0x5f2d2463u ), 19);
            PositionX = (ushort) ( ExchangeShortBits((uint) PositionX - 0xdd12, 1) ^ ObjectId ^ 0x2ed6 );
            PositionY = (ushort) ( ExchangeShortBits((uint) PositionY - 0x76de, 5) ^ ObjectId ^ 0xb99b );
        }

private static uint ExchangeShortBits(uint data, int bits)
        {
            data &= 0xffff;
            return ( data >> bits | data << ( 16 - bits ) ) & 65535;
        }

        private static uint ExchangeLongBits(uint data, int bits) { return data >> bits | data << ( 32 - bits ); }

        }

        private static uint ExchangeLongBits(uint data, int bits) { return data >> bits | data << ( 32 - bits ); }

This reply contains answer for my question:


(x-32)>>6
(y-32)>>6

but these mathematics changes every huge update in Conquer.exe and not working for the client what I deal with

so how to get actual X,Y values from memory ?

Best way to find out what encryption they are using is by reversing it. Open up conquer in your disassembler and look for the CMsgInteract packet with interactType UseSkill. Look around for string refs/packet IDs and you will find it.

Try to use pseudocode generators to make it 'readable' and convert it to your langauge.
