Are you just tired of the objects that are on the floor and used the Dark Matter material to make it stuck in mid-air? There's a solution to your problem. In your Tools Bag, find the Anti-Gravity Tool, the one with Apple sign, and stick it to the object you want to be on mid-air. Delete ( Just kidding ) Tweak the Anti-Gravity Tool and set the Anti-Gravity to 0%, then increase the Dampening to 100%. Don't mind the Buoyancy, set it to 0%. Then, boom. You got whut you want. Yay, .

Umm...isn't that obvious?

Um, I'm just sayin'. For those who dunno. Trololol. 8D

Thank you so much, I was always wondering how people did that!

Umm...isn't that obvious? He put this in the correct section of the forum. It doesn't matter if it is easy, because he gave more information on simulating dark matter than the game does. The game never really talks about dampening, so it is good that he brought it up.

The LBPWiki is a wonderful thing. To add a few more tidbits of relevant info, if you use this method your object will become immovable and frozen in place; it cannot be rotated or moved, be it by its own forces or by outside influences. If this is not what you want, read on. In order to make a derelict object stop rotating without stopping its trajectory, activate a simple rotator set to 0% speed and 100% deceleration. Likewise, stop an object from moving without stopping its rotation, use a simple mover set to 0% speed, 100% deceleration. Such an active mover will also enable other forces to push the object aside if needed to. Once the pushing stops, though, the object will come to an immediate standstill. Lower its deceleration value to make it slow down gradually. If you want an object to firmly resist being pushed out of its trajectory (like Superman stopping a train without getting pushed away), stack multiple movers (or followers if that is what you are using) and have them all be active. This will multiply the strength of each mover. Likewise, if you are using a follower on an out-of-center spot on an object and you want the edge to rotate towards a certain location, you will find that the object behaves irraticly; that is because the engine will try to rotate the object around its calculated center rather than the spot where the (look-at) rotator is placed. You can force the follower to take charge by stacking a bunch of them; kind of like the object is bolted; the rotator will be forced to circle around this virtual bolt. Alternatively, if above method doesn't work for you, you can always put the mover on a separate piece of holo that is bolted to the original object; the object will then be rotated around that bolt.

You know you dont have to change anti-gravity to 0%. Dampening does it all. Besides, all 0% anti-gravity does it make it so that it falls. When you do that, youre turning off the anti-gravity, so its not like it would help anyway.

Two more things: though the name is "anti gravity", setting it to >0 will not make it an opposing force to gravity; it will not make an object fall upwards. It will just no longer be influenced by a downward gravitational force. Attract-o-tweaker and gel will still attract it (in case of a sackbot), though. Another thing of note is that, like in real physics, despite something floating in zero gravity, it still has mass. Among other things, this means that colliding objects can crush one another and in case one has more mass than the other (depending on size and material) the most massiv object is harder to give way. Since LBP doesn't have air friction either, this makes it a nice virtual environment to do physics experiments: place emitters on opposing sides and have each fire off an object at equal speed but of different mass. Score nerd points!

Two points for Gryffondor! Haha, nice trick, stoping rotation but not movement, that's really useful! Thanks!

Since LBP doesn't have air friction either... Since when? It doesn't have true aerodynamics/hydrodynamics, but it's always had a primitive implementation of drag (http://en.wikipedia.org/wiki/Drag_(physics)) and skin friction (http://en.wikipedia.org/wiki/Parasitic_drag#Skin_friction). The former is easily proven by launching a small block of pink floaty through the air - it'll eventually come to a stop. The latter is a bit more difficult to distinguish from torque (http://en.wikipedia.org/wiki/Torque), but there's a pretty long discussion about it here (https://lbpcentral.lbp-hub.com/index.php?t=23824-quot-Aerodynamic-quot-properties-of-wheels). IIRC, neither force applies to 'ethereal' materials like hologram, sticker panel, and deadly gas. This was the reason I was forced to use hologram for the spaceships in my Spacewar clone - solid materials exhibited decaying orbits. :/

I think this thread is getting more complicated than it needs to be...

Looking forward to a Large Hadron Collider level from you one day. I think this thread is getting more complicated than it needs to be... I am glad to see discussions escalate in an upward spiral.

Sorry to complicate this thread even further, but I don't think anyone mentioned the special case of In/Out Movement? While Dark/White Matter is completely Static, a 100% Dampened material is still perfectly able to move In and Out between the basic Layers

Likewise, stop an object from moving without stopping its rotation, use a simple mover set to 0% speed, 100% deceleration. I never knew that, but I can actually make use of this in the level I'm building right now. Thanks Kris. (I still can't believe how the most "stating the obvious" thread in LBPC history has actually became a source of useful information....incredible!)

While Dark/White Matter is completely Static, a 100% Dampened material is still perfectly able to move In and Out between the basic Layers Which has been very handy for me recently. @Cakeinator.... have you actually looked at the in-game tutorials? Because I get the impression that you haven't. They're very handy, so even if you think you know something, I'd still look at the tutorial... because you may find out even more wonders!

Also, if you didnt know yet, the in game tutorials give you stickers and materials to build with! And some of the free stuff you get is really worth it! (not to mention the knowledge, and Stephen Fry's loverly narration of the whole thing!)
