VB.Net Map Editor problem >_>

[Growlith1223]

So, Development on my Map Editor has gone smoothly EXCEPT for when i use Layer….


Comes up with this shiz… Everything else works fine but once it 'tries' to read Map.Tile(X, Y).Layer(i)

all hell breaks loose and errors pop up. That's really the only thing i have to fix and it's pretty much ready.

I have tried using a Class, nope. Structure, nope. tried everything i could think of, nope.

It's the only thing that's set to Nothing. it's the only thing i can't get a Tooltip from(the thing where in debug, you hover over and you get the value of it) it. If anyone can seriously help fix this, it would be GREATLY appreciated <3

Sincerely,

you are trying to use an object of a class when you don't have one made, that's what that means.

' this here makes an object out of a class

Dim objectName as ClassName

objectName = NEW ClassName(Parameters)

you are missing this setup somewhere.

[Growlith1223]

I already have it. hence Map.

[RyokuHasu]

it doesn't give that error just because it want's too, you are trying to use an object you dont have properly made somewhere.

**It doesn't do anything**

[RyokuHasu]

Then give the line it errors on.

[Ertzel]

Can you post your code showing the where this error is happening?

[Growlith1223]

```
G.DrawImage(Tex_Tileset(1), Map.tile(X + 1, Y + 1).Layer(i).x, Map.tile(X + 1, Y + 1).Layer(i).y)

```
just gonna say that it has nothing to do with this specific line. it's any line that has Map.Tile(X, Y).Layer(i)

[pandacoder]

Then Map.Tile or Tile.Layer is null, and you are trying to access members of a null object.

[RyokuHasu]

Well until you can be more specific I'm going to tell you the same thing, The error means SOMETHING hasn't been properly made into an object. It may not be your map, but it's SOMETHING.

That's all I can say until you print a stack trace or give better debugging information.

```

Try

Your code here

Catch exception as NullRefrenceException

exception.PrintStackTrace() ' or similar debugging statment

End Try

```

i have already fixed it with the help of Ertzel, no need for anymore help.

For anyone wondering, this was the fix for layers:

```
Public Class TileRec
Public Layer(MapLayers.Fringe2) As TileDataRec
Public Type As Byte
Public Data1 As Long
Public Data2 As Long
Public Data3 As Long
Public DirBlock As Byte

Sub New()
For x As Byte = MapLayers.Ground To MapLayers.Fringe2
Me.Layer(x) = New TileDataRec
Next
End Sub
End Class

```
