I figure I'll need to inport BMP sprites for objects, and I think I'll have to use sprite collisions for destruction, but I'm not really sure how to get it all working right.
Can anyone help?

Wow, this must be one of the first realistic "help me make a game" posts I have ever read. Most people want to start out trying to re-create Vice City or something equally as ridiculous. But Galaga is easily possible.

How far have you actually got? Have you got the images already prepared ready for use as sprites?

Cheers,

Rich

Like Rich said. Good idea.
I can help if you get stuck.

If you're using DBC enhanced or DBPro my first suggestion is to use the .png format to store your images and textures.

My second suggestion is to decide on 2D (sprites) or 3D (objects). There are pros and cons to each but either version will be good starting projects.

My third suggestion is to finish a 2D version, then convert it to 3D.

If you do 2D use sprite collisions to detect when to destroy your sprites. For 3D use object collisions for the detection.

Sup Rore welcome to the forums and Happy DB Coding.

I answered your similar question in this post and started to make a mini example of how it could be achieved in 3d.

In that post you also referred to r type and thats what i started to address which can be customised for galaga as its the same principle just vertical instead of horizontal.

I also made u a mini snippet to fool around with in the 3d version like heartbone suggests before i found this duplicate post

Thanks a lot for the support so far guys, I'm going to try 2d first. I have sprites ready, but am not sure how to get Galaga style attacks working, with a laser/bullet.

Okay, I've started with the very basic stuff, inporting my sprite, and getting control and... I'm already having problems. I've been taking some things from examples, and trying to figure out what they do, and how to edit them to suit my needs. I have absolutely no idea how to get the play control working.

See anything wrong with my code?

Sup Rore assuming that you have a 72x63 pixel bitmap named ship.bmp in the folder,
run and play with this program.

It should start to answer your questions. You must refer to the command documentation in your User Manual to get an idea how and why a command is used.

Thanks a lot, Now all I need are enemies and shooting... I think I'll start with enemies that need to be dodged.
I Can't quite figure out how to get more than one sprite working properly... none of the commands you gave have any obvious ways to affect specific sprites..

Okay, I'm using a tank theme as a placeholder, and now have sprite for the tank, (which is controlled, thanks to heartbone's code) And a Landmine, which I plan to have come down the screen in a loop, and cause a game over on collision. My problem of the hour, is how to get it (the mine) moving. I looked at the walking sprite tutorial, but couldn't figure out how to implement it. here's my latest code, can anyone help fix my problem?

To get the mine moving insert these lines into your loop in between the two Sprite statements.

Inc Z : If Z > RGTLIM Then Z= 0
Inc M : If M > 400 Then M= 0

I dont knwo why that would happen, allthough you can make you program shorter (not much, but shorter) by using


instead of


doesnt make a difference (that Ive noticed) in performance, but if you are loading a lot of pictures, using the load image command is much easier then using the load bitmap and get image commands.

Yeah bone, I noticed that right after I logged off.
I've now got everything working except making the game end if you collide. Here's my current code.


Any ideas on how to
A: efficiently get more than one mine on screen at once
B: get SHotting straight forward to work?

Strangest thing, When I added a second mine, and collisions for the second one, the first collision stopped working, and the second started acting strangely. it's in my code.

All I need to know, besides how to fix that, is how to get GALAGA style shooting working.

Thanks for all your helps so far.

Well you have Sync On instead of Sync. That's one problem.

Hmm... none of my problems have to do with sync though. I'll fix it.

Maybe you changed the wrong Sync On. You need to change the second one to Sync. The first one is OK as Sync On.

Before you change too many things test your changes.
In other words change only one thing at a time until you are confident as to how the changes will affect the other existing code.

Besides understanding how the attached code works,
MAKE SURE THAT YOU UNDERSTAND WHY YOUR CODE DIDN'T.

After looking at the source you may understand why a programmer should never name a variable O.

The CN part of the program stops the colour change from being played more than once. If you were to put a Rem in front of CN = 2 and CN = 3. The colour would repeat like a machine gun. That colour change would be your collision routines, and you certainly don't want them to repeat.

Have you looked in the code base? I belive there is now an example of an old 2D shooter like galager in it.
