Thx for the Hint of the Convex Hull2!

Anton_S

I'm glad it's resolved

Your plugin "Split" is excellent!
It's a part of the "physic" engine or your own cooking?

Just copied code snippets from SketchyPhysics and some cooking of course

Okay, I've fixed enough bugs. Moving to MSPhysics now!

By improving SP, I learned quite a lot, especially the ideals and approaches to take when writing MSPhysics.

It's now up to Chris Phillips and other interested in such plugin to enhance and add features. I will no longer keep supporting SketchyPhysics as I am quite busy with College and need to make some progress in MSPhysics. Other than that, I won't mind answering questions on how to properly use SP.

Hi Anton,

Sorry I haven't been more involved during your flurry of input - you've done really well. When I get time away from current work I've got some cool projects to build which you have enabled.

Thanks again for your input.

Also, just checked out MSPhysics - great stuff - if I can help test or something then please keep me in the loop.

Thanks ashscott, and no need to be sorry. Some descent features were supposed to be added to make SP3.5 as attractive as the plugin's first release, but I was too lazy too do that

A typical example of problems with transformed objects is this:

A typical example...

Thats very strange. When I added option readback collision geometry to the vehicle, there were 3 collision shapes below it, which came out from nowhere. That's some strange effect with default shape. Meantime for the fix, set vehicle shape to convexhull2 or compound2 for proper collision generation. Convexhull2 is preferred as it's the fastest.

I can't reproduce this in SP3.2, so that's some bug by me, which must be eliminated. I will look into fixing it.

Thanks for report.

If You add option readback collision geometry to the wheels You will sea that it happens only with flipped objects/groups ...

Anton_S

Okay, it is fixed now! Please download latest version and see how it goes. Thanks for report, faust07

faust07

It works. Thanks again Anton. The door to the "Physics World" in SketchUp is wide open ...

I think I see what you did there

faust07

Oh no, Anton I don't want to nerve you. I cheered too soon. A model that ran in SPh3.5.3, jolts in SPh3.5.4 a little ... Probably the steering blocks are squeezed out laterally from the body of the truck. I hope the GIF example shows what a little.

strange behaviour ...

Thanks for your documentation, patrick. I placed this in first post, as part of reference.

Is the behavior different in SP3.2? Are you assigning same shapes to SP3.2 and SP3.5.4? Meantime, if they are squeezed out, to fix it, set most surrounding parts and the cabin to Not Collidable.

No, in SP3.2 it did run OK. There were only the other reasons for crashes, you've solved so wonderful! In your SP3.5.3 this truck moved correctly (after resetting some mirrored objects).

Can you send me the skp model (private message if you prefer), so I could investigate.

Where are the physics joints and the wheels? A lot of parts of the model are deleted. Do you mind reuploading? Don't worry about size. You can erase the file from attachments after I download it.
