I'm back, also. Haven't been on since August. I forgot about SP for a while.

Yeah. Think of each object in the simulation as a class and the onTick, onTouch, etc are the event "subs".

It's likely you're shooting them too fast for the physics engine to register a collision, try lowering the strength to around 50 and see if it works. Also check the parent object collides correctly. Emitted objects actually lose all properties except their shape; they will also be visible even if the parent object is hidden.

Is it OK to upload RC1 modules to 3dwarehouse ? You could look for car modules uploaded to this forum and see how it was done before.

ah, ok.. that works (⌘A) thanks

Make it a group (you probably did this anyway), then right-click, SketchyPhysics, Shape, and select 'staticmesh'. It won't be able to move, but the sphere will be able to collide with every face in the building. Making complex, movable shapes is a little harder; basically, you need to make a compound shape out of lots of the normal shapes, like box, cylinder, etc, then group them all together and set that group's shape to 'default'. If you're making, for example, the body for a moving car, make a simplified shape out of these basic shapes, and group them together with the main car body. Inside the overall group, set the main body's state to 'ignore', and hide the physics objects.

What version are you using? Is it a bugsplatt or a normal error? What are the details of the error? When exactly did the error occur (when you played the simulation, or when you opened the model?) Open the SketchyPhysics UI (next to play/pause) to change joint settings.

Happens to me too and lemme guess when you click "joint settings" nothing happens... i thought i was the only one with these problems

You're welcome

Just idea Another method can be use SketchyPhysics Not used for a while but you can make articulations between boxes Use last version for have more options here old version 2.1 (of course you can "hide" joints So your board can fall down on your volume from the top (must dig again inside this crazzy plug because all forgotten Launch animation Save / Exit Reload / erase all you want [image: jcV3_skph.jpg] skph.skp

Yes. Go in to the group with the box and motor, then right-click on the box --> SketchyPhysics --> State: ---> then ether "ignore" or "nocollision", it dosn't matter right now. And if you don't want to se the box after this ignore stage, just "hide" it under right-click-menu. /hpnisse PS. More info about ignore and nocollision state: Ignore: http://sketchyphysics.wikia.com/wiki/Ignore Nocollison: http://sketchyphysics.wikia.com/wiki/NoCollision

Anyway, this is the best introductory tutorial: http://sketchyphysicstutorial.googlepages.com/

Great, Wacov, thanks for the help. Is an oscillator in SP3 beta, or RC1? Cos, if it is in RC1, then, I don't know where to find it... Thanks ~GoldenFrog~

Thank you ! It works very well !!

Thanx Wacov! Still fooling around: Sang, lost at sea. [flash=640,480:t5rsudk3]http://www.youtube.com/v/0kQph4ETwPk&hl=nl&fs=1[/flash:t5rsudk3] "I spilled some coffee..." [flash=640,480:t5rsudk3]http://www.youtube.com/v/69_rkW06auE&hl=nl&fs=1[/flash:t5rsudk3]

ahhh i see, thanks

it was so natural "G" for group. Thanks a lot

My (shorthand) one is: accel = 0.001 deccel = 0.001 control = righty thrust = 5000 @speed=0.5 if @speed==nil @speed-=deccel if @speed>control && @speed>0.5 @speed+=deccel if @speed<control && @speed<0.5 @speed+=accel if control>0.5 @speed-=accel if control<0.5 @speed+=deccel if control==0.5 && @speed<0.5 @speed-=deccel if control==0.5 && @speed>0.5 setVar("speed",(0.5-@speed)*thrust) Essentially, you just need to stick the script in onTick (doesn't matter where), and getVar("speed") in the thruster field. At the top of the script, you can change the rate of acceleration and decceleration, the controller (leftx, lefty, rightx, etc...), and the thrust multiplier (how much thrust you want overall). This script is shortened and simplified from my original version, slightly modified for use with a thruster. However, I'm really not sure you'll get the result you want...
