Hi all,
I'm using euAllegro (awsome library =D) to write an RPG and using the included
Mappy editor to create the maps. I am getting a machine level error when trying
to display the map on screen. Here is my code:
include euallegro.ew
include file.e
integer ret
--Initiate Allegro library routines
ret = allegro_init()
ret = install_timer() --Set up timer routines
ret = install_keyboard() --Set up keyboard handler
set_gfx_mode(GFX_AUTODETECT, 640, 480, 0, 0)
--Load main game map into memory
ret = MapLoadABM(current_dir() & "\\test.fmp")
--Set the palette to that of the map
MapSetPal8()
--Create a bitmap to contain the map image
atom a
a = create_bitmap(640, 480)
clear(a)
--Draw map image to virtual bitmap
MapDrawBG(a, 0, 0, 0, 0, 640, 480)
--Display virtual bitmap on screen
blit(a, SCREEN(), 0, 0, 0, 0, 640, 480)
sequence key
key = readkey()
MapFreeMem() --Free map from memory
destroy_bitmap(a)
allegro_exit()
And here is the error message:
C:\Euphoria\DOWNLOADS\euAllegro\PROJECTS\Chieften\euallegro.ew:4871 in procedure
MapDrawBG()
A machine-level exception occurred during execution of this statement
... called from
C:\Euphoria\DOWNLOADS\euAllegro\PROJECTS\Chieften\chieften.exw:30
Help!

The reason for the machine level error, is cause it's trying to blit, or draw,
outside the parameters of the Assembled Bitmap Image produced by Mappy.
Remember to measure properly, if you have a 10x10 map, with tiles in it that are
16x16 pixels, you'll ultimately end up with a 160x160 image of the map.
