Hi Zheng3, this looks awesome!

I've printed out the file "zheng3_penny_catapult.stl", which contains 8 pieces. I'm not sure how this is put together. Is there a pic of how you put it together?

Thank you :)

I printed a full 2-player set (2 catapults, 6 flags, and 16 blocks) as a donated prize for a Chinese Auction.

It received the 2nd highest number of tickets.
I also had a few people ask me to print a set for them, but with 26 hours of print time, it does become expensive.

So this is basically a remake of the classic game Castles and Catapults?

What slicer do you use for these? I used Slic3r 0.9.9 and the hole in the base for the flag is tiny (like it could fit a toothpick not the flag pole) and the flag's hole is a little closer but it still doesn't fit. My printer is calibrated well so I'm assuming it is a slicer issue.

I've printed two sets (two different color ABS) with Reptier Host 0.56 and Slic3r 0.9.9 and I didn't have any real problems getting the flags together. Obviously I have to trim the edges of the poles where they might have slight rims from the first layer or the brim but the holes and poles fit together with out much work.

Something that just popped into mind is that I print 3 at a time so that the head moves around a bit allowing the layers to cool before applying the next which helps keep the dimensions as intended. An active cooling fan might help too.

Hello Zheng buddy,

do you have a Seej internet site not blocked by the chinese firewall? as a rule of thumbs, anything with .org or .net are usually blocked by the wall...

Ouch...still fails...any handy pdf that could be downloaded here :)

can you email me at jim@zheng3.com? I'll send you whatever you need.

Thoughts on adding neutral terrain and/or a grid for movement?

Good suggestions. Wikify 'em! http://wiki.s33j.nethttp://wiki.s33j.net

We've been freely moving our Seej engines but keeping them behind the leading edge of our fortifications just so noone saunters up to your castle with a ballista and blows it apart. (Core Rule #3)

I was working on some rules for moving wheeled vehicles based on the length of the vehicle and the degree of wheel articulation, but shelved them until there was actually a wheeled vehicle to move.

Seej owes some of its design DNA to a game called Clay-O-Rama originally published in Dragon Magazine (Issue #125).

Seej looks like a fun idea, but also tricky in that it's so free-form that it could become unplayable, balanced only by rule 3.

The innovation in this game looks like it's in designing and deploying fortifications. I'd suggest that you need to have very clear rules as to what's acceptable, in the core rules. Rather than being constraining, I'd suggest that clear limitations on what's allowable will encourage innovation, as
people try to come up with cleverer ways to block projectiles while remaining within the allowed space.

I see that you've added "Strongly suggested: Castle walls should be made of interlocking blocks no larger than 5x3x3 cm. Blocks should fit together loosely enough to give the opponent a sporting
chance of destroying a wall with a 10-penny bombardment. (See Core Rule #3.)". I'd suggest that this kind of restriction needs to be a core rule. And I'd suggest that the restriction needs to be a bit more precise. For example, I think you'll need to end up with something less like "If a design unb
alances the game, shelve it until your opponent has designed a countermeasure" and more like the kinds of design restrictions that you saw in Battle Bots. Perhaps something like:

  • Fits within 5x3x3 area (so one piece cannot block a flag)
  • Weighs no more than 1/4 lbs.
  • Made only of plastic (i.e. n
    o filling bricks with lead).
  • Cannot lock together - pieces can stack, but must not snap together, and must be able to slide apart, and must not protrude into each other more than 5mm.

Those are all good points laird, and thanks for posting them to the Seej Wiki. Hopefully you'll have kickstarted a discussion about what's fair and what isn't in a game of Seej.

My intent in laying down the Core Rules is to provide a minimal framework upon which anyone can build their House Rules.

I imagine local house rules will prevail until two very different "houses" run smack into each other, at which point there will be much spirited debate and creative evolution.
Should be exciting.

Yes, reminds me of Crossbows and Catapults. Except now we get to print our own weapons and defense systems. I can't wait to see how the rules evolve and how to incorporate new designs. There should be some kind of point system to allow moving up to better weapons and defenses.

Great idea!

New rules will wind up at http://wiki.s33j.nethttp://wiki.s33j.net as people develop them.

Looks good! Printing one now, see if my brother likes it.

Hi zheng,

I made some modifications to the design of the catapult ( http://www.thingiverse.com/image:140288http://www.thingiverse.com/ima... ). What tool did you use to generate the stl files? Tried to import them back into openscad, but openscad protested about some of them: side_brace and winding_key. I remodelled side_brace in openscad
since. Care to share the source files?


i used to have this game a long long long time ago i love it. great post
