Units, Measurements and more

Archive: 81 posts

I found this on the LBPbuilder.com forums, and it has a lot of good information that I don't think is succinctly available on this site.


This might be handy for anyone doing any precise actions. I welcome any corrections and I hope people have helpful additions.

Units
Small Grid - 2.5 units
Medium Grid - 5 units
Big Grid - 10 units

Measurements
Sackboy Height - 10 units
Squeeze Height - 5 units (area he can squeeze in, might be smaller)
Standing Jump Height - 12.5 units
Standing Jump Distance - 25 units
Running Jump Distance - 50 units (I occasionally managed 55 units rarely)
Level Height - 2220 units
Level Width - 3932.5 units
Level Depth = 3.8 layers (.8 = The thin layers)

Material Weights and Properties
Also, I found this here, which provides equivalent weights for all materials. This is based on a 5x5 single z-axis depth block of material. (Thin layers weigh 1/5 of a thick layer)



Material Weight Resistance Friction
Metal 20 8 3
Stone 20 8 3

Bolts, Sensors, Magentic Keys, Magnetic Switches, and Eyeballs are also weightless. It appears that all of the Connectors (String, Pistons, etc) are weightless if properly connected on both ends. If the connectors are only attached on one end, they operate as anchors on the loose connector but the string/piston/rod inbetween is weightless. Other creature parts, spikes, explosives, and rockets all have various weights. If you need to figure the weights of anything, Peach Floaty blocks in 5x5 sizes attached either directly or with string make for good ways to figure it.

Connector Notes


Connectors appears to hate having a minimum distance of zero. Alway set it for a minimum distance of 0.1 or it will detatch or wig out.

Connectors appears to hate having a minimum distance of zero. Alway set it for a minimum distance of 0.1 or it will detatch or wig out.
It seems that there is about 2.5 units worth of hardware involved with a Connector (like a piston, string, rod). So if you want a string to stretch across a 20 unit span of space, set the "maximum distance" to be 17.5 units.
Similarly, pistons/winches will always have at least a ~2.5 gap when fully retracted.
If you want a Piston or Winch to be flush when fully retracted, use the way they don't clip and attach them above instead of below their anchor object. So if there is a ledge where the Winch would be connected to, attach it to the top of the ledge instead of below. In this way, you don't have to account for the 2.5 units of connectors and it can be set to be flush with the anchor object.

Noticed a lack of mention on rockets, so I did some testing of my own.

For starters, a 5x5 rocket (using the OP units) weighs 9.3. But after I found this, I decided to see if I could figure out how much rocket thrust "weighs". 2-3 hours later, this is what I came up with.

The tweak menu for rockets is separated into 21 different settings when you use the D-pad, ranging from 0 on the far left to 20 on the far right.

And a graph of what I found. It's somewhat exponential, but I found that there wasn't a very obvious pattern (unfortunately).

http://img248.imageshack.us/img248/1949/lbprocketgraph.jpg



It seems that the sackperson sensor and the mag switch have a max range between 200 and 250 units, or in the ball park of 1.5 screen widths at max camera zoom out.

Weirdly, the exact range seemed to vary a bit depending on what switch mode was set (speed,on/off,etc) and even more weirdly, my tests with a mag on/off switch had it turning off at a larger range than was needed to turn it on, and I believe my results varied a bit as well depending on if I moved the key or the switch. It all seemed quite finicky at the edge.

Incidentally, while I had never measured it before, I could have sworn the range was greater at some patch point in the past, but perhaps I'm mistaken there. Even now the + sign never stops flashing as you increase range, and it's difficult to see the range perimeter as it gets near the limit, but nonetheless it stops growing just a ways out of camera view.

Hope this saves somebody else a bit of pondering time...		2009-02-17 16:40:00

Thanks so much for putting this up here Rorsch- I mean Walter (wink wink)

I think most of us who have tinkered to any great length with the "create" side of things, have a rough idea what the properties of each material are.

That said, there's something so much more accessible about seeing them listed in a table with assigned numerical value.

The piston section was particularly good to know. There's a few times I've been left scratching my head wondering why the **** thing won't fully retract when min length is at zero!

Good to know, incredibly useful. Thanks a bunch.		2009-02-19 18:15:00

Hey, no problem, I tend to doubt anything I read on the 'net myself.

And an addendum: the 50 units figure relates to thick layer pieces. IIrc, thin layer objects weigh 1/5th.		2009-02-23 13:51:00

I have no idea, but you could find out by using floaty to "weigh it" see how much floaty it takes to make it float.		2009-03-18 04:32:00

Easy way to weigh checkpoints- Put single life checkpoint about 8 units away from double checkpoint in the air. Pause create mode. Take some Peach floaty and the circle tool. Make the circle 2 units larger in every direction than the checkpoints. "Click it" (press X) right on top of the single life checkpoint, dead in the middle. Repeat for double life checkpoint. Exit popit, unpause create mode, and see which one falls faster. (Or if they're the same)

We should really assign names to these different measurement units. I'm gonna call these weight units LittleBigOunces (LBOz) until they add water so we can measure in proper LittleBigMetric. ;-)


Sackboy weighs 50 units.

I just tested it myself and he weighs 12.5 weight units.

Go into Create Mode, put down 12 medium-grid-size squares of peach floaty and 2 small-grid-size squares, join them together, and while paused, have Sackboy stand directly in the center of this floaty object, then unpause and you'll see him float completely neutrally.

Here are some more measurements... I only measured the Basic Kit in the Tools bag.

small grid units.

That's confusing weight measurements with area measurements (and I don't blame you, because we haven't come up with different names for these units).

The measurement of the peach floaty is based on 1 medium-grid-size square, which is 5 piston/rod/winch length units square, or 25 length units square.


This is based on a 5x5 single z-axis depth block of material. (Thin layers weigh 1/5 of a thick layer)

So according to the original post, 25 length units square of peach floaty neutralizes 1 weight unit (which I'm going to call a LBOz).

So here's the calculation.

( ( Number of medium-size-grid squares * ( Length of single medium-grid-size square * Height of single medium-grid-size square ) ) + ( Number of small-size-grid squares * ( Length of single small-grid-size square * Height of small-grid-size square ) ) ) / Number of squared units to neutralize 1 LBOz
( ( 12 * ( 5 * 5 ) ) + ( 2 * ( 2.5 * 2.5 ) ) ) / 25
( ( Number of medium-size-grid squares * Area of single medium-grid-size square ) + ( Number of small-size-grid squares * Area of single small-grid-size square ) ) / Number of squared units to neutralize 1 LBOz
( ( 12 * 25 ) + ( 2 * 6.25 ) ) / 25
( Total area of 12 medium-grid-size squares + Total area of 2 small-size-grid squares ) / Number of squared units to neutralize 1 LBOz
( 300 + 12.5 ) / 25
Total squared units / Number of squared units to neutralize 1 LBOz
312.5 / 25
End weight
12.5 LBOz		2009-05-03 21:39:00

Units
Small Grid - 2.5 units
Medium Grid - 5 units
Big Grid - 10 units

Wait... are you saying that a 1 thickness in small grid is half as much as a medium grid block? Wouldn't the medium grid be 4 multiplied by the small grid?

Because 4 small grid blocks equal 1 medium block...also this is the same for the big grid.

Anyways, I thought this was very useful. But, I decided to actually make my own, because I don't like decimal points It doesn't help much when your trying to be exact.

Either way, I printed this out Will be very useful for the future, because it's sitting right next to my ps3 controller 		2009-08-05 19:45:00

Ah, I see, so 2.5 units is the height and width of the block...

I have a big physics question i think could stump a few people here

Someone should calculate how heavy the materials are in circle form...

That shouldn't be too hard, and it's more of a geometry equation than a physics one, since we already know the weight per area. I'm way too lazy to figure it out though.		2009-08-06 08:17:00

Area = pi * (radius squared)

But most of the circles in the game actually have visible sides, so you would have to count them up and base your equation on that to truly figure out the area.		2009-08-06 13:36:00

Oh darn your pernickety ways BSprague Especially when you are right.

Well, the area of an icosogon is:

http://upload.wikimedia.org/math/0/d/4/0d4ce295dda2a527df94230c62bc25f8.png
Where T is the edge length.

Just need to work out the edge length from crosssectional distance and we can formulate an equation from the square it fits into. I'm sure that would be much more useful and easy to use than approximating it to a real circle

Although that assumes the weight is calculated in this way. Have you noticed that the engine implies a curve on "circular" objects - you can't get the flat endges to go flush with another object

Yeah I was trying to use a circle as a 20 sided shapa and butt it up against 2 walls so I could position mag switches accurately, and it wouldn't. It's even weirder if you make a circle huge and try to run on it My guess is that it greatly reduces the calcualtions for collision detection - hence the fact that swapping circles for squares in wobbley logic doesn't appear to change the "edges" thermo - circles genuinely do have 1 edge.

It's a way to make rendering more efficient. 20 sides is a lot less to render than 360 sides for example. The collisions are detected as though it is round though I believe.		2009-08-07 01:58:00

When you attach pistons, yes. But try doing what I said and making a massive circle, then running on top. Or pushing the flat edge against a wall.		2009-08-07 22:06:00

In the OP table of material specifications, what does the resistance measurement mean?

Also, is the friction measurement just a relative guideline to compare which materials have more friction, or does it have a specific meaning in terms of length/volume of some standard block of each material.		2009-11-02 19:33:00

Another way to stae sackboys weight is in squares of materials. Sackboy weighs as much as one small grid block of metal, half a small grid block of wood, and 3/4 a block of cardboard. (all in one plane.) I did some testing like this, and weighed eery material like this.2009-11-04 06:40:00

Actually, you need to delete half the edges as well. Copying a circle, rotating by (360/40) degrees and placing over the top gives a very jagged "circle" (just think how you get a 8-pointed star when you place a rotated square over itself).

The thermo point is still the limiting factor though.		2009-11-04 10:33:00

VERY usefull
Thank you!
I'm printing it xD
GOOD EDIT:
I get some info about level size:
Level Height = 2220 units
Level Width = 3932.5 units
Level Lenght = 3.8 layers (.8 = The thin layers)		2009-11-08 18:10:00

Level Lenght = 3.5 layers (.5 = The thin layers)

3.8, to be exact. A thin layer shape weighs 1/5 of its thick layer equivalent, meaning that a thin layer has got 1/5 of the thickness of a thick layer. There's a total number of 3 thick and 4 thin layers (not counting the create mode hover layer and the glitched layers).		2009-11-11 01:06:00

Sackboy is 9 units tall, not ten. 2009-11-11 02:33:00

Sure doesn't look like only 1/5 the size. I would say maybe about 7 or 8 could fit in, but who am I to judge, your the master.

And if you actually create a near perfect smooth circle, which I did, (Takes up a good amount of thermo) when you jump on it, sackboy wriggles around on landing because of all the tiny defects.		2009-12-09 07:45:00

It seems that the sackperson sensor and the mag switch have a max range between 200 and 250 units, or in the ball park of 1.5 screen widths at max camera zoom out.

Weirdly, the exact range seemed to vary a bit depending on what switch mode was set (speed,on/off,etc) and even more weirdly, my tests with a mag on/off switch had it turning off at a larger range than was needed to turn it on, and I believe my results varied a bit as well depending on if I moved the key or the switch. It all seemed quite finicky at the edge.

Incidentally, while I had never measured it before, I could have sworn the range was greater at some patch point in the past, but perhaps I'm mistaken there. Even now the + sign never stops flashing as you increase range, and it's difficult to see the range perimeter as it gets near the limit, but nonetheless it stops growing just a ways out of camera view.

Hope this saves somebody else a bit of pondering time...		2009-12-11 03:45:00

This is indeed the case. It's called hysteresis and essentially the line at which you switch is not a line but in fact a zone. Say for example you wanted the switching point to be at 50 units. What you may find is that as you move the magnetic key inwards, the switch doesn't switch on until it's at 48. Then on the way out it won't switch off until the key is at around 52.

It's to prevent jitter at the point at which it switching occurs. It's annoying sometimes, but it's quite consistent.		2009-12-11 13:41:00

Still roaming around being overly technical rtm? Good to see things haven't changed in my absence.		2009-12-13 18:53:00

Noticed a lack of mention on rockets, so I did some testing of my own.

For starters, a 5x5 rocket (using the OP units) weighs 9.3. But after I found this, I decided to see if I could figure out how much rocket thrust "weighs". 2-3 hours later, this is what I came up with.

The tweak menu for rockets is separated into 21 different settings when you use the D-pad, ranging from 0 on the far left to 20 on the far right.

And a graph of what I found. It's somewhat exponential, but I found that there wasn't a very obvious pattern (unfortunately).

Fun fact: LBP2 seems to be using the weight of a sackboy as the unit of weight measurement (as seen in the In/Out Mover). So you might want to recalculate your table ... and drop it on the wiki while you're at it. Or I will. 2011-02-03 23:55:00

this is great! but- how much does a block of water weighs? or (hopefully equivalent) what's the relative weight of all this items in water?2011-03-16 06:52:00
