Changed Sprite #s so you can add up to 40 waves instead of 3.

Hi,
I made a 2d Shoot Em' Up Game a while back and decided to turn it into a game engine. The Code is really basic and easy to read and
with all my comments I hope anyone with basic programming skills can make a simple shooter game.

Heres a Picture of a Game I made with my engine

` This is a 2d Shoot Em Up engine by Stephen Sokolowski
` Use this as a Basis to make your own Shoot em up games
` To Start your Game, Enter the Name of it In the Title Screen

This is mainly for people who need help starting there first game. Just Make your own images and Load them in the correct spots with the correct image # (Same goes for the sounds). I will include my images and sounds to my game I made with this engine in the codebase soon.

Plz leave me some feedback of what you think so far.

lmao Oh, well ya its all coded for you just put your own images, sounds, and tinker with the values to make a game of your own.
If you want add to the engine or use it as a reference.

Also Im a newbie at DarkBasic too. Started programming in DarkBasic in the end of May and my only other programming knowledge was with a bit of Html and Javascript.

hm... I did find it a little helpful, however, my version of darkbasic keeps highlighting loop and saying image not found or something like that. I put in all the images i would use and didnt change anything else, and that happened.

I use darkbasic classic and i practically have no experience.

hmm not sure did you include sounds also? anyhow on my website you can download 2 games I made with it.

Edit: I copied the code above and put in some of my images and sounds and it works fine. So double check you didnt miss type and also check you are using the correct format for the images, sounds and music ( .bmp, .wav, and .mid ).

I'm very new to DB but i can understand 90% of the code. Does help from being a VB programmer i supose and i used to do my own DOS based games in the past.

The Problem with the Pics as i found out from experiance is just a Typing mistake or u referenced it with an incorrect file path.

oh and one more thing. i noticed that in the pic the enemies have some grey around the front of em. just change it to black and set the transparancy of the image (or if it can be done with a sprite) to ON (1). should make it a bit cleaner.

But as for the code.... DAMN!!! that is a bucketful. very usefull though and maybe i'll look into it.

could it be re-done as 3D keeping it top down but using 3D modles instead of sprites ? Hint Hint (i'm planning summat like that)

you better get used to alot of code...considering that's mostly comments it adds up to barely anything...(not that the comments aren't helpfull...i'm sure it was a pain to put all of them in there...)

my current project is at nearly 4000+ lines...and i don't remark very often (bad habit...or lack of habit

)

anyway...nice work skeletor! i've been thinking about doing a 2D shoot 'em up game on the side...and this may give me just the head start i need

(i haven't tried 2D in DBPro yet...)

@ DLS
Well I suppose it could be done with 3d, prolly would have to re-code just about everything though. Anyhow I havent touched 3d in DB yet, and I am no artist/modeler. So as of right now I wont be making any 3d games / engines.

Anyhow Im going to try to learn how to make tilebased games then after that Ill prolly move to 3d. Just got DBP online and Darkmatter so I should be able to do some cool stuff down the line.

Well If any of you guys have questions email me at skeletorsks1987@yahoo.com and be sure to visit my website www.angelfire.com/games5/db_games

Thanks again for the feedback

Glad I could help.

Im actually working on a more advanced 2d shoot em up game. I havent started programming but I have been jotting down the ideas. Im shooting for more advanced AI, and better gameplay.

@ raar
Its just a basis for 2d Shoot Em Up Games. If you want it to be unique you would have to know how to program so you could change it to your likeing.

Actually This was based off my one 2d shoot em up game "Saddam's Army" then I turned that into really nice clean code which I made all simplified varibles to make this. Also my other Games like Bumper Pong, Break Out, and Tank Wars werent made with this though.

I am however going to be working on a more advanced version soon. Better enemy AI, More Guns, Grenades... ect.

Other than that thanks for the Feedback

i looked into it the other day and its very very good code.

higher up i said about doing it as 3D so i decided to actually do it by looking at the code and converting it to do 3D.

i wouldn't of known where to begin with it but now i do i'll be sure to add Skeletor to the list of credits when its done.

quite a few ppl will get a mention but he'll be at the top in bold with flashing lights.... well sort of

Well, as an example it's pretty cool. But it isn't the most efficient way to code it and it can't really be called an engine yet. I think you can functionize some stuff there to make the code reusable.

Ive updated the code big time... Turned a bunch of stuff into functions and placed it into a seperate .dba file, and also placed the area where you load your media into a seperate .dba file.

You can now type in a number to determine how many enemies per wave there will be and how many waves. (Up to 500 enemies total and up to 20 waves) You can specify the number of lifes you want and it will automatically place the Player Life sprites on screen.

The link to the new Engine is here
