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!
