How does Playable Piano block chat?

[karl-police]

How does Playable Piano Addon block the chat when sitting on it and you can only leave when clicking TAB.

[B]Addon:[/B] [url]http://steamcommunity.com/sharedfile...ails/104548572[/url]

What does this Addon do that when I click E on the Piano, I can't access to the chat while I am on the piano.

[chikkenslayer]

function RemoveChat()
	hook.Add( "HUDShouldDraw", "NoChatBox", function( name )
		if name == "CHudChat" then
			return false
		end
	end )
end

function BringBackChat()
	hook.Remove( "HUDShouldDraw", "NoChatBox" )
end

should be this.

[B]This inside gmt_instruments_base\cl_init.lua[/B]

// Override regular keys
hook.Add( "PlayerBindPress", "InstrumentHook", function( ply, bind, pressed )

	if IsValid( ply.Instrument ) then
		return true
	end

end )

What should it do, how does it work?

Returning true in PlayerBindPress prevents the command that is bound to that key from running. If you wanted to block a specific command, say the chatbox, you'd do
[lua]
hook.Add( PlayerBindPress", "BlockChat", function(ply, bind, pressed)
if bind == "say" or bind == "say_team" then
return true
end
end)
[/lua]

Fine, now on a specific gamemode it doesn't block the chat, why?

There is very likely other code that's overriding it.

So an another code can bypass PlayerBindPress?

If it's done poorly, yes.

And where can I find something like "BlockChat" are there other commands like "BlockChat"
And why does it add a hook instead of doing an if statement?

[B]Edit:[/B]Ah, every gamemode is else, like I don't need to add the hooks anymore just if it does something new.
