Hi everybody. Thanks for your feedback and sorry about this delay in replying. I've looked into the difficulties some of you have experienced with my game and have come up with some possible answers.
@Dr Tank: I was originally going to do the player as a 3D object although in the end decided to opt for the classic 2D look. It seemed to gel more with the rest of the game. With 2D, she has roughly the same number of frames as the guy from Space Harrier. About your query with the horizon scrolling faster than the furthest part of the chequered plane, perhaps I'm not observant enough but I can honestly say I never noticed this.
@Jimpo: I think the lack of textures on certain objects is related to my use of the 'clone object' command as opposed to media combined in the exe file. You said the player character, ground and backdrops displayed ok. Although I'm assuming the obstacles, enemies and enemy missiles don't? These use the clone object command and after some research I discovered there were problems associated with that command and textures.
@White Fang and Monocoder: That runtime error is more puzzling. It might be a codec issue. There are 4 short AVI animations in the game, saved out in XviD MPEG-4 direct from Blender. I considered converting them to WMV although the quality was noticeably poorer (and the file size larger). Although I have read elsewhere that this particular error is actually a bug in DBPro.
As regards your memory query Monocoder, Antagonism is a fairly big game, featuring 13 OGG files, hundreds of PNGs, and the aforementioned animations. All of these are loaded at the beginning so the exe runs smoothly. When I checked Task Manager the memory fluctuated between 180,000 and 360,000.
I might do an updated version in the future taking your suggestions and concerns into account. Thanks
