Weird piston bug (new to me)

Archive: 13 posts


ok so Im working on my newest level, and I have a piston that will not become stiff.. its set to stiff (ofcoarse) and Ive tried setting it to X then check again on stiff and it still bends at the joints... so I deleted it and made :blush:a new one, that one wont get stiff either.. anyone ever had that happen before... (btw I know how freaking bad all that sounded)2009-01-29 22:45:00

Try to be clearer:

A piston connected to what? How big it was? Material?
It's obvious you cant move a huge metal/stone wall in mid-air with a single piston, it will break!

no its all connected to pretty easily managable stuff, and the piston works fine, its just not still.. Like the setting for making it stiff seems to not be working, but there are other pistons right beside it that are working fine.2009-01-29 23:09:00

Hmmm... weird.
Never happened to me.
I hope it is not a newfound bug!

Have you tried to delete the piston, save the level, exit the game, reload the whole thing and make a new one?

yea lol actually just tried that one, to no avail.. not sure what its deal is, but from the way it works, I think I may prefer it this way, maybe LBP just knew it would be better that way.?.2009-01-29 23:27:00

I have seen what you describe, stiff pistons that are not as "stiff" as they should be.

I've also come across another bug several times where an object attached to a stiff piston will start to turn on itself and the piston will eventually "break" all on its own.

I have no idea what causes these problems. I just tend to delete and remake the piston (and sometimes the object it is attached to) until I get it to work right.

I had a similar problem before when there were moving parts on the end of the piston, the piston would support the weight of the main object it was connected to, but not anything that was bolted to it (even if it was cardboard)

do you have anything like that on your piston?

you need to create a 'channel' for the object to run it. Possibly add more pistons.2009-01-30 17:24:00

I've had this exact problem before. See this thread:

https://lbpcentral.lbp-hub.com/index.php?t=t=7998

I've also had problems with pistons (set to stiff and connected to objects that have moving parts) wanting to bend even when the game is paused! There is diffidently some small bug relating to pistons on stiff connected to things that have moving parts. The elevator I created had a series of pistons connected together with cardboard blocks in between and it caused all kinds of problems no matter if they were set to stiff or not.

hey thats actually what I ended up doing, seemed to work fine.

but yea as for moving parts there were none, It was kind of a complex object, but nothing was moving. It could have been though like the basic set up was a long piston from left to right hooked to darkmatter and a block, then the piston in question was between the block and the object... so it would be pulled up by the piston, then pulled to the left by the other piston... seemed to work pretty good though even with a limp piston, once I built some kind of track to keep the object from getting stuck on the scenery and breaking the whole thing.

I don't know what's going on with my level, it doesn't have to do with pistons, but regular bolts, I have a bolt attached to a platform, with full strength, and once I go into play mode, the platform starts to spin, acting like a wobble bolt, I don't get why it's happening honestly, and all these bugs are starting to tick me off.2009-01-30 18:51:00

Let me copy something I wrote in another thread. I know this thread is a little bit old, but I seem to be having similar issues, but on a worse scale...


I seem to be having trouble with pistons right now. I have some dark matter, then two identical pistons going to some dissolve, then another two identical pistons going to another dissolve, then at right angles towards each other there is a long piece of dissolve.

An ascii diagram would be:

Dark matter...
| .......... |
Diss. ... Diss.
| .......... |
Dis--Dis--Dis
The dashes represent pistons. The dots are just to correct for the auto-spacing.

The problem is the pistons won't move in an identical fashion, even when grid is used and switches are used to precisely time them. I had to have the second stage pistons out of sync by 0.4 seconds for them to line up, and that's when they have both worked off an identical switch system. (permanent on/off from the same starting point)

What's even worse is that inevitably as the pistons try and calibrate themselves, they go unstiff despite being set to stiff. The whole thing wobbles and quite often just dismantles itself.

I've tried every trick I can think of to make sure everything has time to adjust, stays stiff and doesn't break, but I just can't get it to work no matter what I do.

I've got a two stage piston system elsewhere in the level, and it works fine. I don't know why this one won't work.

So the pistons are acting up in two different ways:


They aren't staying stiff while they are trying to compensate for each other.
The aren't staying in sync despite being on identical setting and fired from the exact same switch.


I might try building it backwards, like the sideways pistons, then the lower up down, then the upper up down. I don't know if that will help it, but it's worth a try.
