Pickup an object

christcm

Does anyone know how I can join two objects during an SP Animation? I have a functional Tower Crane but I would like to simulate it picking up a load. I can't figure out how to lower my hook and attach the load to it. Any help would be appreciated.

Ok there has been no response yet but this is what I have done so far. Since I can't get the objects to attach in the animation I have made a hook and a ring. The hook is on the crane and the ring is attached to the load. I have checked the collision properties and the hook and ring both are the correct shape for their intended purpose. However when I get them into place the hook slips right through the ring after a second of trying to lift the load. Is there anything I can do to prevent this?

Can you upload the model, it makes it way easier to troubleshoot.

I have figured out how to pick up the load. I just needed to beef up the size of my hook and the size of the ring (in cross section diameter). I added a clasp on the hook to keep the load on as well. I tried to attach the model but it is too large.

Hello!
Is there any way to pick up somethinge with a script?
I have one script:


ontouch{|toucher,s,p|
   if getVar("var1")==1 
     case toucher.name 
         when "NAME"
            connect(toucher,"fixed")
      end
   else
      ontouch{} #turn off ontouch event.
   end

But this script do not work, cause when it hit an object will the Sketchup and Physics freeze.

So, is there a script that can be turned on with a "getVar("Var")==1", and when the "var" is 0 it will release the object, just like pneumatic vakum.

Thanks for any help!

ontouch{|t,s,p|
   if getVar("var1")==1 && t.name=="NAME"
                connect(t,"fixed")
      end
      ontouch{} #turn off ontouch event.
}

There you go, but remember you can't upload the model to the warehouse cause your using the June 27 version of sp. you can post the model here though.

Thanks for that, but it will freeze when the "hook" touch the box. Why??
Se if you, or someone else can get it to work.

PICK MASKIN.skp

(all stuff is controlled by sliders)
thans again.

phy

if slider("var1")==1;setVar("var1",1);else setVar("var1",0);end

put that in the ontick in place of

slider("var1")

only problem is once it rejects it, it rejects it and when it picks it up it picks it up

a simple idea would have been to use a controled magnet which has some stabalising around it to stop it from spasing out. simple is always better, why need long scripts

christcm

How would you use a controlled magnet? I started with a magnet but it didn't cause the two objects to stick together for me.

hpnisse

I didn´t get the script idea to pickup an object to work, it will always freeze.

and if I use a controlled magnet: the SP.Simulation wont start, and when I press "resetPhysicsSim button" this box come up:

error resetting the simulation: : undefined method ´/´ for nil:NilClass

´resetSimulation

wierd??
(and there can not be the Physics Installation that did´t work cause when I start a new Sketchup and start it will work just fine)

Anyone that can fix the problem with either the script system or the magnets?
thanks:D

what version are you using?

so I guess it is SP3x
