TI-Trek Icon Making Contest
Published by KermMartian 3 months, 2 weeks ago (2019-11-11T14:07:38+00:00) | Discuss this article

As many of you may know, in recent times I have been taking steps to remove direct Star Trek likenesses from this project. The badge logo has been replaced, and we will be changing some of the Trek-specific system names to things more generic. This is not at the behest of anyone, we're doing it to avoid any potential copyright issues down the road.

To this end, we need to replace the Enterprise icon in the screenshot above. The shield bit will be replaced with a gfx_Circle() so you need not worry about the blue outline. As many members of TI-Trek's team have already contributed graphics, I decided to open the floor to the whims of those users who may be interested in the project and contributing in some way.

Objective

Design TWO (2) 32x32 icons of an original ship that you would like to see included in this game. The first icon should be a top-down view and the second should be a side-view. The icons may use any color within the XLIBC palette EXCEPT black, which is used as the transparent index (this means make any transparent areas of the icon black).

Submission Guidelines
  1. You may submit a design by posting a link to your submission in the attached forum topic, or emailing me at the address you can find there.
  2. Your submission must include the following, compressed into an archive:
    • Two 32x32 sprites, one a top-down view and the other a side-view
    • A text file, wherein which some form of identification (either forum name or actual name), is included
  3. The contest will close on the November 30th, 2019.
Judging
  1. The entries will be reviewed by TI-Trek's graphics team, who will act as the contest judges.
  2. Submissions will be judged based on: the originality of the design and how aesthetically-pleasing the design is.
  3. The top 3 submissions will win.
Prizes
  1. A plaque recognizing your contribution to the project
  2. An in-game contributor badge (when I get that functionality working)
  3. Inclusion of your icon in the default project assets.
  4. Your sprite and (user)name in the game's in-game and written credits.

Editor's Note: Although this is not an official Cemetech contest (this project is under the sole auspices of ACagliano), we like to encourage collaboration and creativity in the community, so go to it, and have fun!

After a delay in the judging, the results of Cemetech Contest 23 are finally here!

As a reminder, these are the categories the entries were judged in:
Quote:
All judging criterion are scored out of ten and then summed for a total score. We will take language restraints into consideration.

  • Originality: How novel and interesting the game idea is.
  • Style: How well the game is implemented visually.
  • Theme: How well the game fits the theme of spies/stealth.
  • Code Quality: How well the game is implemented. This is a combination of readability, speed, documentation, and optimization.

In third place is Mystery Maze by matkeller19, coming in at 40 points. Great job!


Coming in at second we have Ace Recon by epsilon5, receiving 43 points. Well done!


Finally, the winner of CC23: Stealthy Spies with 48 points is Omicron 34 by Captain Calc. Congratulations!


Both Hunt: An RPG by Argus and Spy Tower by bdoggamer were also quite impressive and are honorable mentions for this contest.

Here are the signature banners for the contest, they should also (hopefully) soon be added as an award that shows up next to your username on the forum.
