I'm having an issue with Blitz3D. The function "CreateWindow" cannot be found. I'm not sure why this is occuring as I am using an open source project

Question

This is a portion of the code for the application below. Blitz3D is stating that the CreateWindow, CreatePanel, and SetPanelImage functions do not exist. Am I missing a library or something?

Global ResWidth% = 910
Global ResHeight% = 660
Global VersionNumber$ = "1.5"

Loadingwindow=CreateWindow("", GraphicsWidth()/2-160,GraphicsHeight()/2-120,320,260,winhandle,8)
panelloading = CreatePanel(0,0,320,260,Loadingwindow,0)
SetPanelImage(panelloading,"Assets\map_logo.png")

; create a window to put the toolbar in
WinHandle=CreateWindow("Map Creator SCPCBR v"+VersionNumber,GraphicsWidth()/2-ResWidth/2, GraphicsHeight()/2-ResHeight/2,ResWidth,ResHeight,0, 13) 
Global MainHwnd = GetActiveWindow();User32.dll
HideGadget WinHandle

There are two different versions of BlitzBasic which you have to distinguish:

• Blitz3D
• BlitzPlus

Blitz3D supports many functions for 3D game development. BlitzPlus provides many functions for GUI design. However, there is no BlitzBasic version which supports both features at the same time.

In any case, you have three options:

• "I don't need 3D features": use BlitzPlus instead of Blitz3D to compile your program
• "I need 3D features, but my GUI does not have to look like Windows style": use a community plugin for Blitz3D to create GUI elements (e. g. Draw3D)
• "I need 3D features and Windows like GUI elements": Implement your game menu(s) in BlitzPlus and the actual game in Blitz3D
