Question about Gravity

Archive: 9 posts


Does anyone know if there is a way to create a platform/elevator that moves your sack person up while
keeping their feet on the ground and not being forced up(ie. launched up to the roof when the platform stops
at the top)?

Thanks in advance for any insight anyone can provide.

Perhaps trigger the material tweaker to sticky when it reaches the top for a brief second??
Or you could make a roof on it just high enough for you to walk in, but will physically stop you flying in the air when it stops? You could make it out of 'invisible material' (glitch) if you want it to look like just a platform?

Yes to make the platform go slowly up, but that is not the answer your looking for .

Mm I have an idea but don't know if it works through. Ok my idea:

1. Make a platform that moves up and down.

2. Put an anti gravity tweaker on the platform only (not outside off it) and put air resistance 100%. When the platform goes up put a sensor at the top that disables the tweaker (so that you can jump again).

3. Now put the same sensor on the bottom and you created an on/off switch for the anti gravity tweaker.

I hope I helped you .

Is there a optimal acceleration/de-acceleration ratio when using
a mover object that I don't know about?

Edit: I tried using gravity tweakers to prevent the lift but due
to the nature of the elevator I created (It has multiple floors) it
doesn't seem to be effective.
For an example see my level- http://lbp.me/v/fggkv2

If you are going to use a mover, then yeah, If acceleration /deceleration are at 100% you'll reach maximum speed/ stop pretty much instantly, so yeah, the best and most realistic way would be to use a mover with acceleration / deceleration set lower, perhaps 40% (play around with the settings to get the best results you kinda answers your own question which was pretty cool, sorry I didnt think of it 2012-09-21 12:47:00

Has anyone used global gravity modifiers to prevent being forced up in an elevator?2012-09-24 20:59:00

Do you mean at the top? if so I find slowing the lift gradually as it reaches the top will prevent that

Yes at the top. Are you using microchip logic to reduce acceleration gradually?2012-09-25 23:53:00

If it's on multiple floors you say I'd use a tag sensor setup.

Setup a tag sensor with a small radius and corresponding tag on each floor. Invert the output, and attach the sensor's output to a timer with the input setting of forwards/backwards. Attach the timer's output to a mover with input setting of speed scale. What this means is that as the lift gets in range of the tag, the speed slows down. You'll have to play around with your speed and time settings to see what works best for your lift setup but that's where I'd start. Furthermore additional logic will be needed to make it work for both up and down, but this will allow you to control the deceleration smoothly.

To avoid the lift stopping too soon (unless you get the timings exactly right!) it may be worth combining the timer's output with a small signal, say 10% to ensure you'll always have a little bit of movement. When the lift reaches exactly where you want you can activate a 100% dampener to suppress this 10% signal.

I haven't played LBP for a while so may be a little rusty, maybe someone has a far simpler and more fleshed out way to achieve what you want. =P But hopefully this will give you a starting point.
