Hey guys once again i'm back. I want to make a 2d breakout style game. I know there is a tutorial for 3d breakotu but i want to make 2d breakout. This is what i have so far.


The first thign i need help with is moving a paddle with mouse left and right. I tryed this many different ways but it never worked. It would only move a tiny bit. So if you can help me with that for starters that would be great. Also Give me some pointers and a foundation to start off of. Screen shot attatched of what i have. Also i did not copy paste code from any where I got it from hands on dark basic pro and chnaged it up. Thanks

I fixed this by storing the position of the paddles x position in the variable xpos# and copied a second "sprite 2,xpos#,870,2" into the do-loop. I also hid the mouse cursor, because it got annoying.

Here is the full edited code:


There are better ways to do this, but thats pretty much the easiest way. That I thought of, anyway.

Thanks, now i just need to know how to keep the abll ocked on the paddle sprite until it launches. If soemoen could help with that that would be great. I think i should have posted this is 2d section maybe mod can move it there.

I believe removing the ball's positioning from the if h=1 and placing it into the main loop, and adding a condition where if h=0(Thus before the click), the ball's x position will equal the paddle's x position. It should also launch from the paddle's position.

Here is the changed main loop:



Does that help?

You're welcome, I'm happy to help.

Not at the moment (Although, I admit, I haven't actually looked for any problems or inefficiencies, so there could be something totally obvious, of the "Enormous Meteor Landing on my House" magnitude, that my internal Radar didn't pick up on)

If you run into any more problems, though, I'll see what I can do to help.

I wish someone else would help too. Now my question is like i am goign to use 2d bricks. So do i just check if sprite 1 is hitting the bricks and then reset velocity and delte the brick. Would i use the sprite hit command. Thanks. If someone has links to tutorials that will tell me how i can make a little level editor to make 2d levels fater that would also help. Thanks in advance.

Am I not good enough? (Kidding, I know you you mean. More people = more efficient, and multiple viewpoints)

Well, I haven't read them, but after a quick search, here are a few tutorials that have to do with making a 2d Editor. Even if they aren't for this particular type of game, I trust you can edit them into usefulness.

Note: A few may be a bit old and outdated.

http://forum.thegamecreators.com/?m=forum_view&t=34076&b=4


http://forum.thegamecreators.com/?m=forum_view&t=158455&b=1- On this page Mobiius wrote a simple editor, 4th post. It's 3D though, so you'll have to rewrite it in 2D, and for breakout in mind (But the principal of map editing is there)

Hmm, that's all I found. While this forum is loaded with information on how to make a particular part of an editor, it is a bit lacking on full-blown tutorials. I guess you could scrounge all the bits of information up into a working database of knowledge though.

By the way, directly related to the Breakout project, I found this tutorial for a 2D breakout game in the Game Creators Newsletter:

http://www.thegamecreators.com/data/newsletter/newsletter_issue_32.html#15

I hope that something in that short list I posted helps.

Sorry, I just realized that the breakout tutorial I gave you was a 3D breakout tutorial, most likely the one you mentioned reading at the top of the page (The universe usually works like that)

As to your actual question, When it hits the blocks, You will want to have it reverse on the y-axis. If I have the right idea about how sprite offset works(I'm more at home working with 3D than 2D), you would reset the Y Velocity, so it goes slower, then multiply it by -1, so it goes down, then delete the brick.

I believe you would use the sprite hit command to detect whether the ball and blocks/paddle collide.

So you were pretty much right in all respects. Again, this is true only if how I think it works is how it works.

(Edit) By the way, Mobiius' editor isn't a tutorial, but a block of code. Thought that should be noted. I found it easy to read, though, so thought I should add it anyway

Thanks so much man. Actually just to give yu an intro i know 3d programming and made a few moni games. Now i felt i should go back and learn 2d programming. So ill look into the tutorials after i come back from school. Once again thanks.

Oh my. When this thread bumped back to the top, I glanced at it and thought it said "starting a 2d breakfast game", and I thought, "how cool!" Maybe some bacon, or pancakes and sausage.

I really need to get my eyes checked.

Yeah, I hear that. Like I said, I'm far more proficient in 3D, but I know enough of the theory and application of 2D that, hopefully, I can be of some limited use.

By the way, in case you haven't checked it (You probably have, but it never hurts to ask), here is a sprite plugin for DBP

When I read what you said, for whatever reason, My first thought was "I'd buy that game"

Hey xyus Thanks,
I was just about to ask for sprite plugins, because the dark basic pro commands are very limited. You read my mind.
Hey do you live in the US. Because i'm thinking we got seperated from the rest of the world. Maybe people in UK can not replky to my post any more.
