@Mr.DarkWeb: That's a good point, didn't think to implement that function, you can get BoneIDs with trial&error or with the lua functions if you know how to use them.
@People who think this is a command: it's not, it's an extension for an addon called 'wiremod', you have to be able to use the 'Expression 2' (from that addon) in order to get this working.

How do you get the BoneID for every bone in your playermodels so you can know which one you are editing?

wtf where do i need to paste this command ? they dont work in the console , help pls

when i try to make my head bigger it says unknown command and then the first thing there is typed

@Ben&RexGaming No, it doesn't, i'm sorry.

@[GMT]Thomasims It doesn't work for me, when I put "(my name):setBoneScale(BoneID, scale) it says unknown command: (my name)

thanks, I guess i'll use the rag doll mover tool then

You cannot do this to ragdolls, the normal bone functions included with wiremod should work on them.

Here's a piece of code that would make your head twice as big:
owner():setBoneScale(5,vec(2))

Breakdown:
-Take the entity returned by 'owner()' (you)
-Apply 'setBoneScale' on this entity and use as parameters:
*a number, the bone ID (5 is the head in this case)
*a vector, the relative size (vec(2) == vector(2,2,2))

can I apply this to ragdolls, and can i get some sample code

It's most likely not what he used, this relies on Wiremod, which needs stools to be used and I don't think Hide and Seek has them.

Does this work on gamemodesexclunding Sandbox like Hide and Seek, because I think this is the mod Vanoss used to make players shrink in this video:
