completly unmoveable entity

hi i am trying to make a entity completly unmoveable as in you cant gravgun it, you cant physgun it, you cant move it by slamming into it and so on, and i have noclue how to do this does any one know?

You could just weld it to the world or something.

[lua]ent:SetMoveType(MOVETYPE_NONE)[/lua] might be your best bet.

You could achieve this with flags, such as:
Enable motion on Physcannon grab
Motion Disabled

But I couldn’t find any info on what the definitions of those are to set the flag, maybe someone else knows.
