Sub or function not defined

[Aurelijus1]

i get **Sub or function not defined** error no this line:

**RenderTextureByRects** Tex_Tileset(Tileset), sRECT, drect

[Joyce]

Probably because it does not exist in your engine. What are you using and where are you copying all this from?

[Aurelijus1]

i have fixed that problem adding this

```
Public Sub RenderTextureByRects(TextureRec As DX8TextureRec, sRECT As RECT, drect As RECT, Optional Colour As Long = -1)

   ' If debug mode, handle error then exit out
   If Options.Debug = 1 Then On Error GoTo errorhandler

   RenderTexture TextureRec, drect.Left, drect.Top, sRECT.Left, sRECT.Top, drect.Right - drect.Left, drect.Bottom - drect.Top, sRECT.Right - sRECT.Left, sRECT.Bottom - sRECT.Top, Colour

   ' Error handler
   Exit Sub
errorhandler:
   HandleError "RenderTextureByRects", "modGraphics", Err.Number, Err.Description, Err.Source, Err.HelpContext
   Err.Clear
   Exit Sub
End Sub
```

but now i'am having other problem **user defined type not defined on this line**
```
Public Sub RenderTextureByRects(TextureRec As DX8TextureRec, sRECT As RECT, drect As RECT, Optional Colour As Long = -1)
```

Again, what are you doing exactly? It sounds to me like you're copying DirectX8 material to a DirectX7 engine which won't work.

[Aurelijus1]

Fixed by changing DX8TextureRec to DirectDrawSurface7

you are right :D

[Joyce]

That might work, but not every D3D8 sub is the same as their older DD7 counterpart. So you may need to rewrite some bits and pieces.

i have found engine that have autotile system and dx7
