How to get info: "Can i read next position in DataPack?"
I tried this:

PHP Code:

if (Pack.IsReadable(Pack.Position+1)) {
    // Do some actions
} 


But it dosen't work.

No. You know what you've written and read from the DataPack.

I have optional write. I will try this:

PHP Code:

//something in code
if (/* some statement */) {
    Pack.WriteCell(true);
    Pack.WriteCell(data);
} else
    Pack.WriteCell(false);

//something else in code
if (Pack.ReadCell())
    Pack.ReadCell(); 


It needed for option pass DataPack through another DataPack
Don't think what i'm crazy. I already do it and this work!

Why not simply do that optional write check again when you read it?

How? This topic about this, i asked: "how do this"?

you should probably just redesign what you are sending into the datapack (i.e. make data = -1)

if ( IsPackReadable( yourDatapackHandle, 4 ) )
{
new blabla = ReadPackCell( yourDatapackHandle );
//Do stuff
}

alternatively, probably

if ( yourDatapackHandle.IsPackReadable(4) )
{
new blabla = yourDatapackHandle.ReadPackCell();
//Do stuff
}

RedSword, do you see IsPackReadable function prototype?

native bool IsPackReadable(Handle pack, int bytes);

It not be even compile if i wrote like you say.

Mitchell, i don't understand that you tried to say.

Figure out how many cells you are going to write before you write them, write the count, and then write the cells.

When you read, you then know exactly how many to read back.

Expect IsPackReadable to be reworked in a future release. It should not be exposing byte count, since item size in a pack is an implementation detail.

I believe it should work now.

I suggest a CanReadCell/String(). Though that's probably what you had in mind.
