Is it not possible to drag anything that is made of stone? As you can see I have a rock with a few LED lights on it and a grapple hook. It's set up so that the player has to drag the rock (to the right of me) to the indentation (left of me) to trigger a switch and platform. Yet I can't get it to move, I've also fiddled with a material tweaker to change the friction and it's not working. http://farm6.static.flickr.com/5230/5751270105_048ea6b3ae.jpg (http://www.flickr.com/photos/littlebigdes/5751270105/) 1. How do I make my fallen rock drag-able by hand and grapple hook? 2. How do I set it up that the LED lights to get brighter as the rock gets closer to the sensor tag and LED lights below? I've already set the tag to closeness and tried the signal strength setting but all the LED light come on instantly when the rock is in range. I must be over looking something really simple and having a stupid moment in my level

I have the exact same problem. I tried a material tweaker and set it to grabbable but its still too heavy to pull. Well thats one problem down.

Assuming you have the material made grabbable in the material tweaker maybe it's just too heavy to move. You could try putting a gravity tweaker on it and see what happens. For the LEDs I think the problem might be that the tag sensor isn't set to signal strength (might need to be set to closeness, not sure) and for the LEDs themselves you need to enable the dimmer transition for them to be able to recieve variable voltage.

Yeap the material is grabbable, even shrunk it down smaller assuming it would make it lighter and it doesn't work. Already tried the gravity tweaker and the signal strength and closeness on the tag. Yes silly me I forgot about the dimmer settings, I think it's on the LED light settings itself, so I'll have a tweak.

Material tweaker set to grabbable, friction set to 0. You still need to be careful about how big it is, but Sackboy can drag stone tweaked this way with a little effort. For your lights, you need to change the input to 'dimmer' from 'on/off'.

is it stuck to the floor? is the level paused? these are some of the simple mistakes i sometimes make. if you really have a problem: make the stone a light material. then take a pic of stone. then stick the pic to the light material. now you have a light material that looks like stone. thats what i do when i cant figure problems like this out.

All done thanks. Tweaked size and the friction to 2% so there's some effort involved and sound from the dragging. The LED lights all set to dimmer. Only small problem is with the friction set low to 2% a sackperson easily slides off the rock and I was hoping the rock could be used as a stepping stone to get up to a switch. It still works and you can jump onto it to get to the switch, but to make it draggable I have to put up with it also being slippery when a sackperson is on it. Unless there's a way of specifying which area has no friction (so your sackperson doesn't float/slide off) and which does have friction on the same object. But I don't think that can be done so I may change the top of the rock to the green leaves/sequin material that on its side as this is not slippery. is it stuck to the floor? is the level paused? these are some of the simple mistakes i sometimes make. if you really have a problem: make the stone a light material. then take a pic of stone. then stick the pic to the light material. now you have a light material that looks like stone. thats what i do when i cant figure problems like this out. That's not a bad tip. I'll bare that in mind, never thought about getting another material and stickering it to make it look like stone. All sorted now. Thanks.

The easier way to do it is to make a small slice of the top the same rock, glued together, with another material tweaker with friction set back to normal.

One little suggestion, why not use two material tweakers - one to make it grabbable and one to make it grabbable with 2% friction. then add a grab sensor to activate the 2% friction tweaker, then send the signal through a NOT gate to the other tweaker (to turn off the friction from that one). Then you can jump on it no problem

Then you can jump on it no problem I'll try this one too, I also put a gyroscope on it so it doesn't fall over or turn when a sackperson grabs it. So it stays upright. Great idea, thanks shane_danger, these forums are great even for the more simple things like a sliding rock. I will post a pretty pic of my set-up for others that may have a similar problem, when I'm done.

Then you can jump on it no problem I tried this set-up which logically makes sense to me, BUT its stuck fast and would not move even with the NOT gate turning off the friction back to normal. I've had to switch the two friction settings round. One material tweaker on the microchip is set to friction 100% and the other placed on the rock is set to 1%. http://farm6.static.flickr.com/5303/5754692355_8a56af5741_z.jpg (http://www.flickr.com/photos/littlebigdes/5754692355/) I inverted the 'output' to yes on the grab sensor and on the NOT gate. So now when it is not grabbed friction is 100% but it's still grabbable. When it is grabbed the signal is inverted and turns off the 100% friction and diverts the signal through the NOT gate to turn on the 1% friction so it moves. Finally when a sackperson jumps on it goes back to 100% so no floating or sliding off it. Sort of a backwards way of doing it but it works.

another quick easy idea to move the stone is place a very small thin piece of glass under the stone so its easy to slide, i used that in one of my levels and it works perfectly, so when you jump on the stone sackboy/girl wont slide off the top

Why make life hard as stone : use glass

Plus it needs to stay put when a sackperson jumps on it and not slide from the force of the sackpersons jump/movement as I'm still tinkering with the ground it goes in to. With glass you don't get any sound of the material against the ground (adds to the effect). But still a good tip.

you could use a thin piece of glass and place it behind the rock so its exactly even with the rock, i havent tried it yet but if you do it that way, you might be able to make it slide easy enough while getting the natural rock sound, it sounds like theres many possibilities just gotta find the right one that'll work best lol ill try to think of some new things and let you know

Use the material tweaker to set the stone to where you can grab then but the anti gravity set to your custom falling settings...

It looks like you may have two different types of rock stacked together. If the material tweakers are not physically attached to the right piece of stone it won't work. Also curious why you have one tweaker on the rock and one on the microchip. It doesn't really matter, just a matter of preference I guess. The logic as pictured should work fine, so I'm a little confused.

I had a similar problem but putting an anti gravity and material tweaker on the stone solved the problem. You just have to barely tweak the anti gravity. Just enough so it can move. A great creator taught me that trick. There a some creators that use that trick when building things like metal robots and such, anything heavy that needs to be lighter.

It's ok, all sorted now. I like how there are many ways to do the same thing with LBP tools. Interesting to see what they are. I've still got a long way to go with my level & polishing touches to do, so this part I'm working on may completely change by the time it's finished.

Surely your solutions are over-complicating things...? Could you not just have the friction altered by a grab switch on the rock?

That's what I have done, I attached a grab sensor to a material tweaker to alter the friction, above in the other posts. Problem's sorted. But yes I do agree it's definitely over complicated.

Just to answer shane_danger, I have two materials tweakers from advice from other people, so I tried it out. One for it to be draggable and the other so it stays put and so your sackperson does not float or slip off the top of it. It's made from 2 materials with a sticker on it. Small bit of sequin leaves material on it's side under the microchip so you can grab it, but it's not stacked 90% of it is just stone. But I did try placing the tweakers on each bit. Didn't work so I inverted it, then again I am totally new to this logic and never actually published anything so I'm learning on the way as I work on my first level. But it works so problem solved. Thanks for all the advice from everyone.

Just add another material tweaker to the rock with friction set to 100 then connect the tag sensor to the material tweaker
