Hi!
i have a problem using incbin and using tstream for loading custom data files...

i need to load a .dat file (a simple sequence of int) normally it works fine but if i include the .dat file in main exe width "incbin" the program crash with the message "Attempt to access field or method of null object"

you can reproduce the problem with this litte test.

1. USE THIS TO GENERATE A FILE .DAT

[CODE]
SuperStrict

Global TestArr:Int[9]

For Local j:Int = 0 To 8
TestArr[j] = Rand(0, 1000)
Next

Global s:TStream = WriteStream("test.dat")

For Local j:Int = 0 To 8
Print TestArr[j]
WriteInt(s, testarr[j])
Next

CloseStream(s)
[/CODE]

2. run this and you get the error...

SuperStrict

Incbin "test.dat" 

Global TestArr:Int[9]
Global s:TStream = OpenStream("incbin::test.dat")

For Local j:Int = 0 To 8
	testarr[j] = ReadInt(s)
Next

For Local j:Int = 0 To 8
	Print testarr[j]
Next
CloseStream(s)

Why ? Where is the problem ? inbin don't work with Stream?
it a BMAX Bug ?

help!!!! ;)

Ciao
Gianluca.

You can't OpenStream to an incbin file as it means you intend to write to it. Change Openstream to Readstream.

...Or use...

OpenStream("incbin::test.dat", True, False)

..Which is all ReadStream() does anyway.
