Re: My idea to encourage people to use Python and make more games with it
@pauliyobo, that wasn't exactly helpful at all.
@Amit, here is how you use FMOD in Python using ctypes:
# initialize the system object
fmod=ctypes.CDLL("fmod64.dll")
system=ctypes.c_void_p()
# all functions return an FMOD_RESULT. So we save that to a variable
# there are helpers for this, we'll do that in a moment
res = fmod.FMOD_System_Create(ctypes.byref(system))
if res!=0:
# some error occurred.
# our system object is now created, but not initialized. Initialize it with 4093 maximum voices, no flags, and no extra driver data.
res=fmod.FMOD_System_Init(system, 4093, 0, None)
if res!=0:
# some error occurred.
# Now we can wrap the error checking in an FMOD callback
# This takes a bit of ctypes magic though
# declare the FMOD_ERRORCALLBACK_INFO structure
class FMOD_ERRORCALLBACK_INFO (ctypes.Structure): pass
# declare its fields
FMOD_ERRORCALLBACK_INFO._fields_=[
("result", ctypes.c_int),
("instancetype", ctypes.c_void_p),
("instance", ctypes.c_void_p),
("functionname", ctypes.c_char_p),
("functionparams", ctypes.c_char_p)
]
# declare the callback
ErrorCallback = ctypes.CFUNCTYPE(ctypes.c_int, ctypes.c_void_p, ctypes.c_int, ctypes.c_void_p, ctypes.c_void_p, ctypes.c_void_p)
def SystemErrorCallback(system, type, commanddata1, commanddata2, userdata):
if type==0x00000080: # error callback
info=ctypes.cast(commanddata1, FMOD_ERRORCALLBACK_INFO)
if info.result!=0:
# error occurred, handle it here
callback=ErrorCallback(SystemErrorCallback)
res=fmod.FMOD_System_SetCallback(system, ctypes.byref(callback), 0x00000080)
if res!=0:
# an error occurred setting the callback and it wasn't setThat's generally how you use it. It looks really complicated (and I haven't tested the error callback code above yet), but it gets much easier after a while. Declaring enumerations also isn't very hard with the Aenum package. The difficulty is declaring float* arrays ahead-of-time.
