DataPacks

DataPacks are a way to store and move around various types of data in SourceMod Scripting. Since some things are not possible in SourcePawn, such as a function consuming a String, DataPacks help us get these Strings and other items where they need to go.

Example of using a DataPack

Syntax:

//writing
DataPack pack = new DataPack();
pack.WriteCell(23);
pack.WriteString("I'm a little teapot.");
 
//reading
pack.Reset(); //resets the index to the beginning, necessary for read.
int cellValue = pack.ReadCell();
char buffer[1024];
pack.ReadString(buffer, 1024);

Creating a DataPack

Creating a DataPack is very simple; all you need is a Handle to write to.

Datapack dataPackHandle = new DataPack();

For more information on using Handles, see Handle API (SourceMod).

DataPack Functions

On you have created your DataPack, you can use a variety of functions to manage the DataPack.

WritePackCell

Syntax:

native void WritePackCell(Handle pack, any cell);

WritePackFloat

This function can be used to write a Float to a DataPack.

Syntax:

native void WritePackFloat(Handle pack, float val);

WritePackString

This function can be used to write a String to a DataPack.

Syntax:

native void WritePackString(Handle pack, const char[] str);

ReadPackCell

Syntax:

native any ReadPackCell(Handle pack);

ReadPackFloat

This function can be used to read a Float from a DataPack.

Syntax:

native float ReadPackFloat(Handle pack);

ReadPackString

This function can be used to read a String from a DataPack.

Syntax:

native void ReadPackString(Handle pack, char[] buffer, maxlen);

ResetPack

This function resets your position in the DataPack.

Syntax:

native void ResetPack(Handle pack, bool clear=false);

GetPackPosition

This function gets your current position in the DataPack.

Syntax:

native int GetPackPosition(Handle pack);

SetPackPosition

This function sets your current position in the DataPack.

Syntax:

native void SetPackPosition(Handle pack, int position);

Disposing of a DataPack

To dispose of a DataPack, all you have to do is close its Handle.

Example:

CloseHandle(dataPackHandle);

DataTimers

DataPacks can be used with timers, in order to send more than one value. For more information, visit Timers_(SourceMod_Scripting)
