Player movement problems

[mathix]

Hello, I'm sorry to disturb you with my 2nd question but here it is:

        private void ClickToMove(float newX, float newY, float newZ)
        {
            BlackMagic wow = new BlackMagic();
            IntPtr BaseWoW = wow.MainModule.BaseAddress;

            wow.WriteFloat(0xD02C00 + 0x8C, newX);
            wow.WriteFloat(0xD02C00 + 0x8C + 0x4, newY);
            wow.WriteFloat(0xD02C00 + 0x8C + 0x4 + 0x4, newZ);
            wow.WriteUInt(0xD02C00, 4);
        }

for some reason this causes an error:

system.nullreferenceexception object reference not set to an instance of an object

while doing

ClickToMove(-585.155f,-4245.82f,38.3248f);

This is rather weird and I see no reason for this not working.

SOLUTION: (Thanks to JuJuBoSc and Yellowspark)

        private void ClickToMove(float newX, float newY, float newZ)
        {
            var wowProc = (from Process p in Process.GetProcesses() where p.MainWindowTitle.Contains("World of Warcraft") select p.Id).FirstOrDefault();
            BlackMagic wow = new BlackMagic();
            wow.OpenProcessAndThread(wowProc);
            IntPtr BaseWoW = wow.MainModule.BaseAddress;
            wow.WriteFloat((uint)BaseWoW + 0xD02C00 + 0x8C, newX);
            wow.WriteFloat((uint)BaseWoW + 0xD02C00 + 0x8C + 0x4, newY);
            wow.WriteFloat((uint)BaseWoW + 0xD02C00 + 0x8C + 0x4 + 0x4, newZ);
            wow.WriteInt((uint)BaseWoW + 0xD02C00 + 0x1C, 4);
        }

-------------------------------------------------------------------------------------------------------------------------------------------------------
Also if you don't mind answering another question I have a function which I'd like to return a string but it has some problems with doing that:

        private void GetCharName()
        {
            BlackMagic wow = new BlackMagic();
            IntPtr BaseWoW = wow.MainModule.BaseAddress;

            wow.ReadASCIIString((uint)BaseWoW + 0xEAEAA8, 256);
        }

Cannot convert 'void' to 'string' is the error.

SOLUTION: (Thank you Yellowspark)

private string GetCharName()
        {
            var wowProc = (from Process p in Process.GetProcesses() where p.MainWindowTitle.Contains("World of Warcraft") select p.Id).FirstOrDefault();
            BlackMagic wow = new BlackMagic();
            wow.OpenProcessAndThread(wowProc);
            IntPtr BaseWoW = wow.MainModule.BaseAddress;
            return wow.ReadASCIIString((uint)BaseWoW + 0xEAEAA8, 256); 
        }

I hope you guys will help me with these small problems, thanks in advance! ^^

You need to use

var wowProc = (from Process p in Process.GetProcesses() where p.MainWindowTitle.Contains("World of Warcraft") select p.Id).FirstOrDefault();
BlackMagic wow = new BlackMagic();
wow.OpenProcessAndThread(wowProc);
wow.WriteFloat(0xD02C00 + 0x8C, newX);
wow.WriteFloat(0xD02C00 + 0x8C + 0x4, newY);
wow.WriteFloat(0xD02C00 + 0x8C + 0x4 + 0x4, newZ);
wow.WriteUInt(0xD02C00, 4);

And for your 2nd question

 private string  GetCharName
        {
            var wowProc = (from Process p in Process.GetProcesses() where p.MainWindowTitle.Contains("World of Warcraft") select p.Id).FirstOrDefault();
            BlackMagic wow = new BlackMagic();
            wow.OpenProcessAndThread(wowProc);
            IntPtr BaseWoW = wow.MainModule.BaseAddress;
            get
            {
            return  wow.ReadASCIIString((uint)BaseWoW + 0xEAEAA8, 256);
            }
        }

BlackMagic wow = new BlackMagic();
wow.OpenProcessAndThread(wowProc);
wow.WriteFloat(0xD02C00 + 0x8C, newX);
wow.WriteFloat(0xD02C00 + 0x8C + 0x4, newY);
wow.WriteFloat(0xD02C00 + 0x8C + 0x4 + 0x4, newZ);
wow.WriteUInt(0xD02C00, 4);

Thank you for the suggestion but now it does nothing :-P It just stands still, no reaction nor an error. Do you have anything else I should try?

[JuJuBoSc]

Add base address.

[mathix]

Add base address.

You mean like this:

wow.WriteFloat(BaseWoW + 0xD02C00 + 0x8C, newX);

Because when I do this I get this error:

The best overload method match for 'Magic.BlackMagic.WriteFloat(uint, float)' has some invalid arguments

??

You need to take a big step back and learn what types of variables can you have in C# and how to convert them to other variables,then learn memory,thnx

As you're entitled to your own opinion I must say that it's my own choice what I want to do and learn. I am looking for an answer, not nagging, thank you.

Got the string working by doing this:

private string GetCharName()
        {
            var wowProc = (from Process p in Process.GetProcesses() where p.MainWindowTitle.Contains("World of Warcraft") select p.Id).FirstOrDefault();
            BlackMagic wow = new BlackMagic();
            wow.OpenProcessAndThread(wowProc);
            IntPtr BaseWoW = wow.MainModule.BaseAddress;
            return wow.ReadASCIIString((uint)BaseWoW + 0xEAEAA8, 256); 
        }

Thank you Yellowspark! :-) +rep!

Still got problems with the click to move though.

[JuJuBoSc]

So you are creating a new BlackMagic object every time you need to pull some data ? No really, he is right, learn some basic programming guide first.

[mathix]

Got it all working, see first post for results.
