Turns out the file was named ship.png but was actually a gif file with the extension hidden (I didn't save it properly) so Max was actually looking for a file called ship.png.gif and obviously couldn't find it.

I've used BlitzMax in the past on Windows but now use Mac OS (Snow Leopard).

My attempts at learning the language again have hit a wall by the fact that images will not load at all when I run the program.

I've tried following the beginner tutorial and referencing the image locally on my HD but the debug tells me that I'm trying to reference a null object.

Code I'm using;

Graphics 800, 600, 0

Type TSpaceShip
	Field X:Int
	Field Y:Int
	Field Image:TImage

Method DrawSelf()
	DrawImage Image,X,Y
End Method

End Type

SpaceShip:TSpaceShip = New TSpaceShip
HideMouse()

ImageName:String = "/img/ship.png"
SpaceShip.Image:TImage = LoadImage(ImageName)

	If Spaceship.Image = Null 
	Print "failed to load Image"
	End
	EndIf
	
Repeat
	Cls
	SpaceShip.X = MouseX()
	SpaceShip.Y = 480
	SpaceShip.DrawSelf()	
	Flip
	
Until MouseHit(1)
End

XCode is installed (since it has to be to compile anything in BMax) but I'm wondering if there's anything else I need to install? Or am I just missing something glaringly obvious?

Try removing the first forward slash from the path in ImageName; i.e. ImageName:String = "img/ship.png".

Also, try:

Method DrawSelf()
  DrawImage Self.Image, Self.X, Self.Y
End Method

Oh - also get into the habit of using Strict (or SuperStrict) at the top of your code. This 'forces' you to declare variables etc before you use them. Much easier to debug that way.

Fixed.
