Filestream, starter issues

[XaronParticipant]

Hey there, I just want to load a binary file and want to store it’s content in either a DataBuffer or into a 2d array. But I already fail while loading:

Monkey

#Import "<std>" #Import "<mojo>" #Import "utils.monkey2" #Import "media/gfx/map.data" Using std.. Using mojo.. 'Inside my class: Method New() Local mapStream:FileStream = FileStream.Open( "assets/map.data", "r" ) If( Not mapStream ) Print "ERROR" End If _mapData = New Int[1024, 1024] 'So basically here I will fill that "mapData" by reading Byte by Byte mapStream.Close() End Method

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

#Import "<std>" #Import "<mojo>" #Import "utils.monkey2" #Import "media/gfx/map.data"   Using std.. Using mojo..   'Inside my class:   Method New()   Local mapStream:FileStream = FileStream.Open( "assets/map.data", "r" )   If( Not mapStream )     Print "ERROR"   End If   _mapData = New Int[1024, 1024]   'So basically here I will fill that "mapData" by reading Byte by Byte   mapStream.Close() End Method

 

My map.data is inside “media/gfx/”

Using that Import I have it within the assets folder then. How am I supposed to read that file? Thanks!

Another question: I’ve seen that “ReadAll()” method for streams which returns a DataBuffer. I guess that would be probably faster? How can that be used?

Basically what I want to achieve is to have that data as a collision mask in a 2d world.

shouldn’t this line:

Monkey

[crayon-5cba13f1b60d0363193649 inline="true" ] Local mapStream:FileStream = FileStream.Open( "assets/map.data", "r" )

1 2 3

[crayon-5cba13f1b60d0363193649 inline="true" ]   Local mapStream:FileStream = FileStream.Open( "assets/map.data", "r" )

[/crayon]

be like this:

Monkey

[crayon-5cba13f1b60d5140565684 inline="true" ] Local mapStream:FileStream = FileStream.Open( "asset::map.data", "r" )

1 2 3

[crayon-5cba13f1b60d5140565684 inline="true" ]   Local mapStream:FileStream = FileStream.Open( "asset::map.data", "r" )

[/crayon]

Thanks, yes could be. I’ve tried that as well, but it didn’t work either.

[JesseParticipant]

my fault it’s “asset” not “assets”.

[XaronParticipant]

No, doesn’t work either. Unfortunately there is no example in the bananas section and the documentation is almost non existent…

Here’s a quick clip of working code for you:

Monkey

method Load( filePath:string ) Print "loading..." If Not filePath Return if ExtractExt( filePath ).ToLower() <> ".mx2map" Then Return Local fStream:Stream = Stream.Open( filePath, "r" ) If not fStream Then Print "XX "+filePath + " not opened" Return End If local id:int = fStream.ReadInt() If id <> -9999 Then Print filePath + " ID error" fStream.Close() Return End If 'do something else fStream.Close()

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

method Load( filePath:string ) Print "loading..." If Not filePath Return if ExtractExt( filePath ).ToLower() <> ".mx2map" Then Return   Local fStream:Stream = Stream.Open( filePath, "r" ) If not fStream Then Print "XX "+filePath + " not opened" Return End If local id:int = fStream.ReadInt() If id <> -9999 Then Print filePath + " ID error" fStream.Close() Return End If   'do something else fStream.Close()

[XaronParticipant]

Awesome, thanks!
