Why isn't this working?
The correct behaviour should be an animation where
the ship spins 360 degrees(10 degrees per frame). Once
it has completed 1 rotation it moves away from the camera
and spins again.
The ship spins just fine but I can't get it to move away from
the camera.



#declare NumColumns = 24;
#declare Columns = 0;
#declare NumRows = 36;
#declare Rows = 0;

#while(Columns < NumColumns)
         #while(Rows < NumRows)
            #declare T = Columns *40;
            object {ship rotate clock*z*360
                         translate < 0, T, T> }
            #declare Rows = Rows + 1;
         #end
     #declare Columns = Columns + 1;
#end

I should probably mention that the camera is
rotated at x*-45 which is why "T" is in both
y and z .

Rows has to be reinitialised to 0 inside the Columns loop.
The second time through the Columns loop Rows still has the value NumRows,
so the Rows loop will not be executed.

#declare NumColumns = 24;
#declare NumRows = 36;
 
#declare Columns = 0;
#while(Columns < NumColumns)
         #declare Rows = 0;
         #while(Rows < NumRows)
            #declare T = Columns *40;
            object {ship rotate clock*z*360
                         translate < 0, T, T> }
            #declare Rows = Rows + 1;
         #end
     #declare Columns = Columns + 1;
#end

I believe that keeping the initialiser close to the #while loop makes it
clearer.  I usually do it as

#declare N = 0; #while( N < Limit)
    ....
    #declare N=N+1; #end

so that it looks more like a for() loop

Thanks guys.
I was doing it all wrong. I was creating a bunch
of ships when I only wanted 1, like this...

#declare T = floor(clock)*2;
object {ship rotate clock*z*360
             translate < 0,T, T> }

As usual I was trying to use way more code than I
needed. What's more, I found the function I was
looking for(in Game Maker image_scale)so I wont
need to use this anyhow. It figures.
