The DB Classic Challenge Thread



[Edit: 10 Dec 08 - DBCC website is fully up to date. Challenges set from October 12, 2007 to current now include details about the challenge.

http://zimnox.com/dbcc/?page=challenges


[Edit: 10 June 07 - New Rule 12 Added]


Here are the rules for the DBC challenges. It's pointless re-inventing the wheel, so I've borrowed heavily from the DBPro Challenge rules and modified them for DBC - I hope they don't mind. (Obviously, all credit to Ric and those involved in originally creating them).

Please read all of them before starting your entry.

1. Anybody may enter any challenge, as many times as they like, so long as all code will run in DB Classic with NO alterations. You can still enter the challenge - even if you use DBPro as long as you follow this rule.

2. No external media is allowed - that includes models and external graphics. In other words, the challenge entry must be a single DBA code listing that others can simply copy and paste into DBC and run it. Any media your program uses must be generated by the code itself.

3. All challenge entries are to be written in the standard un-enhanced version of DBC. You can actually use any version of DBC, but for the benefit of those who do not have the Enhancement Pack, you may NOT use any of the additional commands if you have them.*

4. The person who wins the current challenge becomes the next challenge setter.

5. The challenge setter is the judge for the current challenge, and must select a winner and a runner up.

6. The challenge setter may enter, but cannot judge him/herself the winner.

7. The challenge setter will set the time limit according to difficulty. The challenge setter may extend the deadline by 24 hours if there is a very good reason, but extensions cannot be made during the final 24 hours of the challenge.

8. If nobody enters within the time limit, the challenge setter must set a new challenge.

9. If the challenge setter fails to judge entries or set a new challenge within 24 hours of the deadline, responsibility for judging and setting a new challenge will pass to the previous runner up. If that person also fails to act promptly, entrants may vote for a winner and new challenge.

10. You may use code from any other entries within the challenges thread for your current entry, so long as you improve upon it in some way and give credit.

11a. Deadlines are always midnight GMT on the day specified. If GMT is not mentioned it should be assumed. This does not disadvantage entries from other time zones in any way as they still have the same number of hours to complete the challenge as everyone else, as they start earlier (local time).

11b. At the end of each challenge, the challenge setter should post and declare the current challenge over within 6 hours of the declared deadline. Entries can be submitted before this 'closing' post without penalty.

11c. If the challenge setter does not close the challenge for any reason, it automatically closes 6 hours after the deadline - after which no more entries can be accepted.

12. Changing a challenge. If no-one enters a challenge - for example if it is deemed too difficult - anyone can post and suggest that the challenge be changed (or modified), along with their reasons for doing so. If no-one has actually started work on the challenge and the majority agree, then the challenge setter can simply alter it or set another one and announce the new deadline.

In the case of a challenge being completely abandoned rather than modified, anyone who has already started work on the challenge and has done more work on it than they would like to abandon, they can lodge an objection.


* It is possible to ignore this rule (3) if the challenge setter has enough support from the contestants to use the enhanced commands and the use of such commands is clearly stated in the challenge description. For example, a very worthwhile challenge may be set using memblocks - something impossible to do if you can't use the enhanced commands.


OK, so that out of the way, on to the very first ever DBC programming challenge...

To be honest, this challenge was also used in the DBPro challenge thread and I had an entry myself - though I didn't win it!

But I enjoyed writing it and it's such an easy challenge, I'm sure everyone will be able to enter - whatever experience level you are currently at. So the challenge is:


**********************************************************
**********************************************************
NEW CHALLENGE
**********************************************************
**********************************************************


The DBC Clock Challenge...

Your task is quite simply to write a program which displays the current time in an unusual way. That's it! Exactly how you do it is all down to your imagination and ingenuity. It can be in 2D or 3D and doesn't even have to look like a normal clock - as long as you can easily read the time using it.

The challenge will be judged on ingenuity and extra points earned for imaginitive entries.

I'll set the period for the challenge at one week - ending at midnight (GMT) on Thursday 18th of January 2007.

Please feel free to comment if you think this should be extended.

Just as an example, here's the compiled exe of the entry I submitted for the DBPro challenge:

http://www.computechtenerife.com/clock.zip (4.4MB)

I couldn't post the source because it won't run in DBC and would require far too many modifications to make it do so.

I will be entering this challenge, but obviously I can't win it. It won't be using this idea though either...

Any chance we can extend the deadline until Sunday? I haven't had time during the week to work on anything. I did have something I put together last week - but it's not very "clockish" though it does display the time. I just won't have any free time until this weekend.

Enjoy your day.

Quote: "Any chance we can extend the deadline"


Yes - I think that's a good idea too.

The DBC forum doesn't get a lot of traffic, so those that said they would take part in the challenges might not have seen that this one has started.

So, we'll extend this one for another week so the deadline is now midnight (GMT) on Thursday 25th of January 2007.

So everyone please, if you said you were interested in taking part in the challenges earlier in the thread, please do so or the post will just die!

This first challenge is a really easy one so everyone can take part. All you have to do is write a program to display the current time on screen.

It doesn't matter how basic it is, though we are looking for originality in the winning entry. It also doesn't have to be anywhere near the complexity of the exe I posted above - that was just one example of how to write a clock that doesn't look like a clock!

Just write a program to your own abilities. You'll soon find out that in challenge threads, no-one is interested in pointing out how 'noobish' an entry is, but instead will show you how to make it better.

And remember, if you are new to programming and have no idea how to start a challenge, feel free to ask and someone will show you!

How To Start

As a continuation of my last post, if you are a new programmer and aren't sure where to start with the challenge, here's a snippet which you can build on:



The DecodeTime procedure simply gets the current time and places the hour, minute and seconds into the numeric values Hour, Mins and Secs. You can then use these variables in your program to do whatever you want.

The code in the main Do..Loop merely displays these values, so you can remove these lines - as long as you leave the Gosub DecodeTime line in.

This thread is so busy I'm in danger of being rapped on the knuckles for making multiple posts!

Anyway, here's my entry for the challenge:



As already pointed out, I set this challenge so I can't win it.

So, if I can make the effort to enter knowing I can't win, those of you who said they would enter could at least have a go right?

It's not technically free. You can only download it if you are a registered purchaser of DBC.

But, if everyone agrees beforehand, this rule can be ignored (notice the little * at the end of the rule). But yes, the plan was to scrap it at some time anyway.

Entry 4

I wrote this without planning it out (the code shows it ) - I had a picture in my mind of what I wanted to happen - that picture never really materialized, but I actually got a chuckle at how it was progressing so I decided to stop working on it and leave it like it is.

Rather than just turn off the pixels to the digits we don't need to display, why not just 'drop' them?

OK - the reults...

I've basically marked according to the following criteria:

1. Imagination. Does it display the current time in an 'unusual way'?

2. Does it display the correct time?

3. Is it readable? How useful is a clock when you can't tell what time it is?

If more than one entry scores the same, as a tie-breaker I decided to judge the most visually pleasing as the winner.


Entries:

Sven - Spheres Clock.
Accurate, but conventional clock face. Very easy to read. Only loses a couple of points for lack of originality.

Lukas W - 3D clock.
A clock using a standard clock face but in 3D. Nice attempt, but unfortunately it didn't actually display the time, though Sven did fix it. Like Sven's entry, only loses a couple of points for being a standard clock face.

Latch - 1. Bouncing Cubes Clock.
Imaginitive and unusual idea. Accurate but not easy to read.

Latch - 2. Rotating Plains In Transparent Cubes Clock.
Also Imaginitive, unusual and accurate but a little harder to read - especially when the plains are at certain angles.

Latch - 3. Matrix Clock.
Very imaginitive and unusual idea - one which I would never have thought of. Accurate and easy to read too. With further work this could become a really nice screensaver.

Latch - 4. Robot Clock.
Not really a clock so difficult to mark. But it's unusual and tells you the time.

Phaleax - Drop Clock.

Digital Display made from blocks that jump into position from the bottom of the screen then drop down when not required. Easily read, accurate and novel idea, technically executed.

Conclusion:

Overall, the challenge was centred around making a clock as 'unusual' as possible so that had priority. The one I was most impressed with and scored highest therefore was:



And a very close runner up was:



Congratulations to both of you and the winner must set the next challenge within the next 24 hours.

Thanks TDK_Man,

It's too bad only 4 people participated in the last challenge. I'm not sure of an idea for a challenge because I don't know if people will participate if they think it's too hard or too easy...

Even so:

[EDIT - new challenge ]

Draw with mouse on 2d screen

Make a program that uses the mouse to draw on a 2d screen. If the mouse is drawing a continuous stroke, there can be no breaks in the stroke no matter how fast the mouse is moved across the screen.

There should be the ability to change the pen colors and clear the screen with keyboard or additional mouse input.

Scores will be based on functionality, ease of use, and extra points for any kind of bells and whistles beyond the basic challenge parameters. For example, if you want to add something like clicking the right mouse button draws a circle, feel free to do so.

Since I changed the challenge because my original choice was a bit complicated, I'll extend the deadline to February 4th 2007 midnight GMT.


[OLD - challenge, no longer in effect]

DBC FLAME EFFECT CHALLENGE

The challenge will be to create a fire or flame effect in DBC. You can use 2d or 3d and the result can be anything from a flicker to a roaring blaze to a flame thrower or anything you can imagine.

Scoring will be based on scales from 1 to 10 in:

Coolness : how does it look?
subcat. to coolness
color
presentation
animation

Ingenuity

The total of the 3 catagories under Coolness will be totaled and that will be the coolness score. Coolness and inginuity will be added to provide the final score.

I'll set the deadline for 1 week from now at midnight GMT

Friday, February 2, 2007

Enjoy your day.

grrrrrr, I hate DBC! It's so primitive.

Without memblocks or any way to access pixel data directly in memory, this effect is just unbearably slow. We're talking about 0.4fps.

For those who don't want to wait forever to see how the effect looks, here's a link to my DBP version with a screenshot from my java version.

I'm OK with the challenge, but I do think it's a little on the difficult side for any newcomers who were thinking of joining in. This might scare them off before they've participated.

But if you want to stick with it, I'm OK...

Here's my paint so far. Can't seem to figure out why my line draws dots instead, it should be working.


Edited code to fix dot bug. My draw flag kept getting reset every loop. Haven't tested (on another machine) but it should work now.

Sure does.

We can do the flame one a little later when there's a few more people interested in the thread. For now we need to keep it fairly simple to generate interest in the thread with newcomers.

@Lucifer:
Not bad! Very concise.

@All
Looks like you guys are knocking out code for this challenge pretty quick! That's great! I hope some others join in too.


I edited the original challenge message but I'll post it here in case anyone missed the change:

Make a program that uses the mouse to draw on a 2d screen. If the mouse is drawing a continuous stroke, there can be no breaks in the stroke no matter how fast the mouse is moved across the screen.

There should be the ability to change the pen colors and clear the screen with keyboard or additional mouse input.

Scores will be based on functionality, ease of use, and extra points for any kind of bells and whistles beyond the basic challenge parameters. For example, if you want to add something like clicking the right mouse button draws a circle, feel free to do so.

Since I changed the challenge because my original choice was a bit complicated, I'll extend the deadline to February 4th 2007 midnight GMT.

Enjoy your day.
