Getting materials from Muscles, Elastics, Rope, etc.?

[vittu]

Hey,

a friend recently asked me on how to print the material from specific "toolgun outputs", like rope, elastics and stuff, into the console or a file. The way on how to this has recently bothered me alot. This is how far I've gotten.

I tried to do this:

for k, v in pairs(ents.GetAll()) do
if ( v:GetClass() == "class_C Rope") then
MsgN(v:GetMaterial())
end
end

(also tried class c_RopeKeyFrame)
things print blank into the console. Nothing else, really.

Tried GetTable and GetSaveTable, but it just returns the classes.

Tried to do

hook.Add('OnEntityCreated','fdf', function(ent) PrintTable(ent:GetKeyValues()) end)

and it returns this:

Nothing useful for what I can see.

If the Rope Tool's code is interesting to anyone, here it is:

I don't think it's impossible to get the material of a spawned rope, does anyone have a clue?

This can be done in several ways, such as using [i]IsConstraint[/i]. If I recall though, elastic, muscle and other springs aren't classed as constraints with this method. If you're looking for those, you'll need to search for the appropriate class. Something like this:

[lua]for _,v in pairs(ents.GetAll()) do
if v:GetClass() == "classname" then MsgN(v.material) end
end[/lua]

The classes I know of are as follows:

phys_spring - elastic, hydraulic, winch, muscle
phys_lengthconstraint - rope
phys_slideconstraint - slider
phys_pulleyconstraint - pulley

As far as I know, all constraints have [i]Type[/i] and [i]material[/i] variables in their table. [i]Type[/i] will be the listed name (case-sensitive) i.e. Elastic, Rope, Muscle. You could therefore search using something like this:

[lua]for _,v in pairs(ents.GetAll()) do
local class, ctype = v:GetClass(), v.Type
if class == "required_class" && ctype == "Type" then
MsgN(v.material)
end
end[/lua]

Beware however, world-to-world (brush-to-brush) constraints aren't registered as constraint-entities, and won't be found.

Yeah I guess that's the problem I had. Thanks for helping anyways.

Also that code is server-side right?

[TheFreeman193]

Yep, the code will only work serverside. After a little more testing, I discovered that brush-brush ropes are of the class [i]keyframe_rope[/i]. Although unlike [i]real[/i] constraints, they still have a [i]Type[/i] member, as well as [i]material[/i], in their table. So, rather than searching for specific classes, you could search through all entities for the existence of these members, and sort your results using the value contained within [i]Type[/i].
