I need func_physbox that cant be grabbed.

I am creating a machine with several interacting moving parts. I
am using func_physbox to make all the parts of this machine. This
machine needs to be able to rotate ect... BUT I do not want pieces of
it to be picked up by the grav-gun.

The machine works fine BUT the grav-gun can affect it.

I have used the proper physics constraints, but for some reason, the
stupid phys-gun can just rip pieces right out of the machine despite
the pieces being interlocked and constrained by physics
constraints. If you move far away from the machine or shoot the
phys-gun the piece you ripped off just magically re-appears where it is
supposed to be.

I have the "ignore +USE for Pickup" flag set but it doesn't work for
the phys-gun. I can't set the "Motion Disabled" flag because then
this part will not move at all. HELP!!!

I have compared my physbox entities with the one in the example phys maps and I don't see any difference.

I really wish there was better physics documentation. Thanks in advance for any help.

increase the mass scale to like 100 experiment a bit with different values as it might affect the way they spin

Profound.

Cool. At least we have some progress. :smile:

This is sort-of working. I put the mass of my physboxes up to
200. I set the "ignore mass" flag on my thrusters, and the
machine still works. Now the phys-gun can not pick pieces out of my
machine but, the physbox entities can still be MOVED by the
phys-gun. Any suggestions?

Doesn't HL2 have some kind of entity that restricts phys_anything movement? Such as lock stuff together, and make sure its firmly rooted in place? Expand on this someone?

Yes. All the Phys_XXXXXXXXConstraints. I am using these
entities, but for some reason, the Grav-gun is overriding my
constraints.

It seems to be a bit of a problem in even official levels. For example, load up dm_overwatch and try picking up the "hotel" sign outside the crossbow building - it comes away from the fixture but pings back there when you try to move it too far.

My recommendation would be to check out the flags of the physbox to ensure there are no options that let you state it doesnt work with the grav gun. If there isn't, then you might want to consider making your machine work using prop_dynamics that are parented to invisible moving entities such as func_doors, func_buttons, or whatever.
