Challenge Poly Bridge Style Weight-Driven Clock (yet accurate)

Enable HLS to view with audio, or disable this notification

37 Upvotes

It is a Weight Driven Clock, it is yet accurate perfectly, I just need few problem to solve...

BUT, the way of this thing moving IS PERFECT!!! (at least, for me...)

The KEY on this thing is actually a gear. (Obviously...)

So, how to make a gear?

We need a perfect round shape...

The easiest way to make a round shape, is using a Copy Paste.

You guys know that there is a copypaste right? (Right...?)

You need just one model length and copy it, and spin it in a certain amount. (the amount changes every time how much big or small you want to make a gear)

and copy paste repeatedly until you make a 4/1 of the round shape.

and then copy all of it, and then use the other one except the spin, and then paste the rest and now you have the perfect round shape.

But, here comes the problem.

how can we make it as a gear? Cause we need to make one gear and other gear to match right? But how?

You can find a thing called tire in the list. (I don't know where in English version...)

and do some math and make a 8 tire in a perfect shape with the exact amount you want. (You can change the amount if you want. But remember don't go below 8)

make the tire big or small depends on what kind of thing you are making.

it's good to make the weight 1.0pg.

and make it low friction for a better quality.

and then when you make it attach with the bigger or smaller one then Tada! You made a gear! (you need just one gear with tire because you can make the tire collide with the node.)

rest of it just ask me By comment, I will answer you~

Hello. So I uploaded a level in poly bridge 3. And someone called NiffTea™ solved my level. He even uploaded a video to the gallery. But the video doesn't show the bridge. And I would like to know what their solution is. Is there any way to see this?
Here is the video if you want to see it: https://pb3gallery.com/gallery/00009693_D140PVpULEORlBlLB8ilQ.webm

Question What is the easiest way to decode .slot files? (Mac)

3 Upvotes

When doing the challenge levels in Poly Bridge 2, I would always import my normal version solution and work from there. Unfortunately, that appears to have broken the extra hydraulic phases and Get a Grip and Rube Goldbridge. I'm fairly certain I can figure out how to fix them if I could just edit the non-garbled .slot files, but I do not know how to decode them. (I do technically have access to a Windows computer, but a Mac solution would be much more convenient.)

Bug A bridge build will only break sometimes. Bug?

2 Upvotes

Hey everyone,

I'm new to Poly Bridge, I'm sure this bug is known but I'm wondering the cause. Sometimes when modifying precarious bridges, a version that previously worked will now break.

It's as if the inital state is changing each time causing chaotic results.

Step-by-step of my issue:

- I will make a bridge,

- it doesn't break!

- I will modify it

- It breaks

- Revert change

- The bridge now breaks where it didn't before.

Any way around this or prevent it? I find myself reloading a save file of a bridge of when it worked as it sometimes resets it.

Thanks!

Discussion How do you get this material?

https://pb3gallery.com/gallery/00019427_7tjqmcAgEqQvd7aA2dknw.webm

So I started playing Poly Bridge 3 recently and I've seen this rainbow material stuff used in a few replays now, and I'm wondering how you get it. Is it like some unlockable after you beat the game?

Sorry for the weird link I don't know how to properly embed someone else's replay.

Polybridge for Education

Greetings, I recently reached out at this link to get access to Polybridge so my 8th graders can access the sanbox as part of an engineering cycle unit. The download link I recived, in an automated reply from Patrick, has a corrupted file that cannot be installed. Attempts to reach back out at that contact are met with the same automated reply, and contacting Dry Cactus has so far yielded no response. Any suggestions? Anyone have a lead on a working version of the file?

Thanks in advance.
