Fantastic Contraption - Fun Online Game & Shareable Creations

In summary, the player must build a contraption to move an object across a gap to a different area. There are many different contraptions to try out and some are more difficult than others.

On Reaching Up, it won't stay in the goal forever, but it stays for a long time.

Pretty cool game. First time at work, I just went through a few levels the obvious way. Kind fun to come up with something a little more interesting.

Why not just lift the square up with a crane?

Or tip it off its wheels to lift it up:

Solving level 20.

Oddly this takes advantage of what seems to be a glitch in the game in order to keep it in the zone.

What's the glitch? The game level extends (far) beyond the initial viewpoint: you can even zoom in/out and drag it around.

If you hit "back" after the victory notice to let the level continue, the "chain" drops down into part of the area it shouldn't. This seems to happen if the "links" are too short. They can also break when they are too short also.

Thank you so much for the link Janus, this is great, plus your designs are amazing.

Lately I have been working on a concept of catapuseless. It is big, complicated, badly designed, and patched.

looks like the physics gets wonky when driven simple harmonic motion shows up. I remember playing with some approximations for that a while back, and a numerical solution will usually diverge and have your pendulum swinging away at light speed in no time.

What's the simplest solution (fewest parts used) to keeping the ball in the goal box, in Around the Bend?

2 rods
1 Wheel

let's see who would beat me :)

oops, this doesn't keep the ball there :(

Got to keep the ball there.

PS: I can do better.

1 stick (from urs)!

This takes >10 minutes

I don't think the ball will stay in the goal. It should push the other ball, ever so slowly, and eventually leave the zone. I suppose I have to let this thing run for an hour to know for sure...

Isn't better (Stick is too long// and assuming that costs are $/metre)
I have it on good authority that branches are sold by the piece regardless of length in that universe.

EDIT: Breaking news, it didn't take an hour. The 1-stick scheme failed to keep the ball within the goal area.

oops, I ran it for ~>20 minutes. It stopped moving

Better yet, http://fantasticcontraption.com/?designId=718066" also works by leaning one against the ball to make the ramp, but it takes so long for the ball to roll into the goal that you would lose patience...
My solution was essentially the same as this. Just move the ball so it starts higher up on the ramp. You get your solution in less than 30 sec.

[Smacks forehead.] You know, for the longest time I thought the target had to remain where it was, I didn't even try to move it. Duh on me! :rolleyes:

Took me a while to figure that out too.

Seems like cheating. I thought perhaps that was the bug you guys were talking about.

no balls, no sticks
There is no way I'm going to watch it for an hour to see if it stays in the goal. If it doesn't I'm sure the height of the drop can be adjusted to make it.
It leaves the box in about 10 minutes. I don't know if there's rolling friction in the code. I do know that collisions are inelastic, but that isn't enough to keep it in the box. Friction is needed. If there is friction built in, then getting the height right will do it.
 
  • #62
sorry, you are right. I adjusted the height to the minimum and it leaves the goal. seems like the big ball should be able to have some effect on stopping it, but no matter how slow I'm going it just pushes through the big ball

If you add a water rod to the wheel then it does experience friction.

This worked!

I think we must need at least one stick
 
  • #64
Agreed.

The quest for the simplest solutions...

In Reach Up, it's possible to make a "staying" solution with fewer than 6 parts. Can you do it?

I'm pretty sure Gokul came up with the same solution. but he's sneaky. that's why he said fewer than 6 parts. that way everyone shoots for 5 and he gets to trump them. got to watch him.
 
  • #67
No, I didn't think of that. That's clever, and makes you so want to do the forehead slap thing.

Anyone got a simpler solution?

Not necessarily simpler but different.
I did not think of that before seeing yours, but it's doable in just 2 sticks
Same kind of principle for the next level :
ming the gap, no wheel

You can do your first solution with a single stick but we're looking for solutions that keep the target within the goal.

EDIT: Here's Mind The Gap with 1 stick, 1 wheel.
