I'm fine with doing total amount of laser items -1 if you have more than 1 items required for working with lasers. So 1 laser and 1 catcher = 2-1 = 1. 2 lasers and 1 catcher = 3-1=2.

If you place 2 glass walls as a corner, it are 2 glass walls, so 2 items. A rounded wall made in hammer would still be 2 in my books. Just because you make it look fancy doesn't mean it can turn 2 items into one IMHO.

Basically the idea is that you are making a white room puzzle, so doing everything to create black tiles just to get the black-room kind of puzzle should be avoided. Yet I wanted to give the creator freedom to be creative, and not restrict in little choices. So if the player gets the feeling the puzzle is mostly white and they have to puzzle where to portal, you succeeded in my books.

As for goo, it does create black portable walls, and so do flip panels. Nothing you can do about, they just count as an item.

Flip panels? That can be both black and white depending on the activated state!

White gel?

Stairs? In-game editor forces black surfaces!

All allowed. They just count as an item. White gel would be pointless, but also allowed. The idea is that you make a puzzle that is white. Sometimes you just need an area to not be portable, and you can use items for that, but given that they count as 1 out of 15 allowed items, you'll quickly fill so its to choose wisely.

What about the stock observation room when I hide it away from the map itself? I don't want the damn thing in my map but it would still count as item....
Otherwise I will have to export the map to hammer and delete it there :/
Edit : Also a cube and dropper count as 2?

Stock observation room: if its not visible, it doesn't count. Hidden mechanics do count when you notice something happens behind the scenes without seeing it.

Cube and dropper is considered to be one item.

Couple of new questions, first one with regards to the compo 020:

- Same as the lightstrips, the observation rooms can be considered as a maneuver to have non-portalable surfaces, should we set a max number as well?

No. The observation rooms count for the max item count of 15. The reason is simple, you cannot place many next to eachother, so its like placing a button on the wall to work as a non-portable surface.

And this is a general question for all competitions since I haven't read about it in the bi-weekly compo rules thread: can we edit the puzzle into hammer at least for only a couple of fixes or tweaks? the portal bump glitch for example is easily fixable into hammer ;) [/quote]
You are allowed to even make a map from scratch in hammer for the bi-weekly competition. The only requirement is that you can play it through the workshop, doesn't require any installation and it is a singleplayer map following that week's competition rules. So creating in PeTI then editing in hammer is totally fine.

For competition 20, with custom hammer objects, every object that is seen as one, is counted as 1 in the max items you may use.

The idea for this challenge is to do the following:
For this competition, I'd like the theme to be gel on a bridge. The solution to your puzzle must involve placing either blue or orange gel (or both) on a hard light bridge. All items are allowed.

And we have a winner!

...with a nice total score of 15 points. (more 1st place votes)

This weeks runner ups are: eMbAh who came second with 15 points, and Piranha.A (Innocentive) who came third with 7 points.

Greykarel, you are entitled to give us the next weeks challenge. Can you reply here before the end of sunday GMT +0, and tell us what you'd like to see in the next competition?

Current stage: The competition is over

The idea for this challenge is to do the following:
Your entire test has to be white, as in, no non-portable walls allowed. In addition, a max of 15 items (of anything, visible and non-visible to the player) can be in the map. An exception are lightstrips, as we do not want chambers that are too dark. You can use up to 20 lightstrips total in your map. Use them to prevent portal bumping or use grating, but they will be counted for the total, so design wisely.

So if you decide to make walls non-portable by blocking them, you'll run out of items pretty quickly. Everything counts as an item that is one piece. So if you place a fizzler field and stretch it up, it is 1 item. If you place goo on the floor, and through some hole in the floor it fills 2 pools with goo, and the user can't see this hole, it will be 2 items. Antlines do not count as items, a laser catcher does. If you are unclear about what counts and what doesn't, please ask.

And we have a winner!

...with a nice total score of 16 points.

This weeks runner ups are: josepezdj who came second with 13 points, and LPChip who came third with 12 points.

Almisuifre, you are entitled to give us the next weeks challenge. Can you reply here before the end of sunday GMT +0, and tell us what you'd like to see in the next competition?

I have 2.

1: A puzzle that has no black portable surfaces and a max of 15 items total (white walls not included)

2: Tunnel vision: create a map where the width of the map is always 3 or less walls. You can go around a corner, but the corner itself is then a max of 3x3. Also, height is 3 or less. If you want to corner into the air, all walls are 3x3 or less until the next corner.

Kind of missed the deadline for this one... So I'll reschedule the winning compo for the other one and put things in order. Sorry for the inconvenience.

And we have a winner!

...with a nice total score of 8 points.
