Wibbley Wobbley Floppy Turrets Falling off their platforms
I decided to make an easy, medium and hard mode of my map Target Practice. There will be moving platforms going up and down, or left and right. But the turrets keep falling off their damn pedestals.
I read somewhere there was an entity specifically for making things not move, or move specifically. Much like the chapter
func_tracktrain & path_track?
func_door?
func_movelinear?
func_door?
func_movelinear?
One of these would work for NPC turrets (well they would but it wouldn't be smooth), I think he wants a phys constraint. (look up phys constraints on the VDC)
i havent decided, but i may use track trains. I need to figure out how to get an object to its original destination at any point regardless how many paths it has crossed. its gonna be like a cross between a shooting gallery and one at a carnival. left and right, up and down. it might come out kinda complicated.
Move to path node 
Just read the valve developer's page
wtf, i never even noticed that one before when i worked with trains previously. I hope it transverses all previous nodes.
EDIT: I didn't find that string to command, however I found teleporttopathnode, which works equally as good. I also discovered that there are a lot more entities that can be fizzled than i thought. Pistons for example. Quick question, can a brush be fizzled? Otherwise i may have to replace them with models
Physic models and brushes can be fizzled, static, dynamic models and brushes cannot.
wait, what? my prop dynamics DID get fizzled. I also noticed i actually checked the box "fizzle everything" So thats what my problem was. DERP 
Thanks for the info.
Now i saw some youtube videos where people used what looked like monitors to see other parts of the map. What entities do that?
You can't fizzle prop_dynamic, check any map, it's not possible, ever.
you can only fizzle physics only, "only".
if that is the case, I just destroyed the laws of gaming physics...
