help with dat reading

[wgrzelak]

As topic I need to reading from memory what title is walkable or not. I don't know why does not work, what is change in structure.

I'm not sure if these addresses are correct, but i think so.

public readonly static int Start = 0x3D466C; //10.39
public readonly static int StepItems = 0xA0; //136 from old version
public readonly static int FlagsOffset = 0x44; //68 from old version

Here my test code:

int itemid = 284;
int start = Util.ReadInt32(DatPointer.Start + Util.Base, Util.Tibia.Handle);
start = Util.ReadInt32(start + 0x8, Util.Tibia.Handle);
start = start + DatPointer.StepItems * (itemid - 100);
int flags = Util.ReadInt32(start + DatPointer.FlagsOffset, Util.Tibia.Handle);

It's working to get name of item, but really I don't know how i can get information about Blocking, BlockingPath.
Also I was analyzed this code: https://github.com/NeoClone/NeoClone.../datReader.pas

This is my scratchpad http://oi57.tinypic.com/20sx92b.jpg and I don't know why flag = 4096 only in first position of this screen.

I hope you understand me and I will grateful if someone help me.
Thanks.

edit: Move this topic to correct department if I made wrong.

The code and addresses looks correct. Just add:

bool walkable = (flags & 4096) == 0;

looking at your code I noticed that you're reading your flag value as 32bit integer, but if I recall correctly, tibia data flags are stored in 64bit range. So, if you don't want to have headaches in the future, it's better to use

long flags = Util.ReadInt64(start + DatPointer.FlagsOffset, Util.Tibia.Handle);

in the last line

Working, I lost around 10h to try make this :P
