Run command when taken damage

[collin4lizard]

Is there a possible way, that I can make my clientside run a command when I take damage. I.e. "say /holster", when someone starts shooting me.

I was thinking I could do sort of an If, else thing with OnTakeDamage but im not too sure on how to go about that.

Thanks in advance

Use the EntityTakeDamage hook.

[collin4lizard]

function GM:EntityTakeDamage( target, dmginfo )
	
	if ( target:IsPlayer() and dmginfo:IsBulletDamage() ) then

		LocalPlayer():ConCommand("say /holster")

	end

end

Ive gotten this far, im not too sure on how to make it work though.

Also i've been thinking it might be more like this:

hook.Add("holsterscript", function()
	if ( target:IsPlayer() and dmginfo:IsBulletDamage() ) then

		LocalPlayer():ConCommand("say /holster")
		end
	end
end)

Neither have worked so far

You aren't using hooks correctly. Read the examples here: [url]http://wiki.garrysmod.com/page/hook/Add[/url]

So, in the same script i'd just need to add a function basically doing what I need, then calling it with hook?

I've revised it a little bit and think im close:

hook.Add("holsterscript", "EntityTakeDamage", function()

local function GM:EntityTakeDamage( target, dmginfo )
	
	if ( target:IsPlayer() and dmginfo:IsBulletDamage() ) then

		LocalPlayer():ConCommand("say /holster")

	end

end

Edit: I get this error:

[ERROR] lua/holsterscript.lua:3: '(' expected near ':'
  1. unknown - lua/holsterscript.lua:0

EDIT Again: I've gotten to a point with 0 errors, i don't think its working however.

hook.Add("EntityTakeDamage", "holsterscript", HolsterScript)

local function HolsterScript( target, dmginfo )
	
	if ( target:IsPlayer() and dmginfo:IsBulletDamage() ) then

		LocalPlayer():ConCommand("say /holster")

	end

end

Although there arent any errors, it doesnt even say "test" instead of /holster

Edit 3: Ive changed it yet again, no errors, but no print

hook.Add("EntityTakeDamage", "holsterscript", HolsterScript)

local function HolsterScript( target, dmginfo )
	
	if ( target:IsPlayer() and dmginfo:IsBulletDamage() ) then

		Player:PrintMessage( HUD_PRINTTALK, "Im testing code." )
	end

end

Lost at this point. Any help would be nice.

Try

target:ConCommand("say /holster")

I put in test instead of holster, still doesn't work.

The function EntityTakeDamage is a server side function, that could be the root of the issue. Anyone have something thats clientside?

[marZ]

[lua]
local function HolsterScript( target, dmginfo )
if ( target:IsPlayer() and dmginfo:IsBulletDamage() ) then
target:PrintMessage( HUD_PRINTTALK, "Im testing code." )
end
end

hook.Add("EntityTakeDamage", "holsterscript", HolsterScript)
[/lua]

[xDoomx]

Like this?

   function GM:EntityTakeDamage( target, dmginfo )
	
	if ( target:IsPlayer() and dmginfo:IsBulletDamage() ) then

		target:ConCommand("say /holster")

	end

end

With yours theres no error but it doesnt say anything in chat

[marZ]

Are you running it Serverside or Client?

[collin4lizard]

[QUOTE=xDoomx;52585588]Like this?

   function GM:EntityTakeDamage( target, dmginfo )
	
	if ( target:IsPlayer() and dmginfo:IsBulletDamage() ) then

		target:ConCommand("say /holster")

	end

end   

Edit: Ninja'd[/QUOTE]

Yours gives me this error:

[ERROR] lua/holsterscript.lua:1: attempt to index global 'GM' (a nil value)
  1. unknown - lua/holsterscript.lua:1

Neither of them say anything when i take dmg

[QUOTE=MarZ333;52585596]Are you running it Serverside or Client?[/QUOTE]

Clientside

[xDoomx]

Put in init.lua, it's a server side hook

[marZ]

EntityTakeDamage is serverside.

That and printing messages on a client is also serverside, client if the client is the calling target.

[QUOTE=xDoomx;52585607]Put in init.lua, it's a server side hook[/QUOTE]

Im making this for clientside wouldn't i need a server, to put it in init.lua?

[marZ]

While testing put it into a file inside or autorun/server

[collin4lizard]

[QUOTE=MarZ333;52585620]While testing put it into a file inside or autorun/server[/QUOTE]

In the gmod folder autorun/server, you want me to make an init.lua file? Im not following you here.

[marZ]

Name the file what ever you want testing.lua even.

Then put that code that I posted earlier into the file and it should work.

[collin4lizard]

Alright, but how do i run the script when in singleplayer?

[marZ]

It should run by itself since it's in autorun.

[collin4lizard]

[QUOTE=MarZ333;52585632]It should run by itself since it's in autorun.[/QUOTE]

Alright, its in there and everything, still doesn't work even when changed to say test.

[editline]17th August 2017[/editline]

Copied it wrong, it DOES work

[editline]17th August 2017[/editline]

But the thing is, I'm looking to run this on a client on a different server. Such as the lua_openscript_cl command

[editline]17th August 2017[/editline]

And, this types /holster in like server chat almost like the print command, not in chat for darkrp etc.

[editline]17th August 2017[/editline]

Anyone got a fix?

[editline]17th August 2017[/editline]

local function HolsterScript( target, dmginfo )
    if ( target:IsPlayer() and dmginfo:IsBulletDamage() ) then
	    target:PrintMessage( HUD_PRINTCONSOLE, "say hi" )
    end
end

hook.Add("PlayerTraceAttack", "holsterscript", HolsterScript)

Tried using PlayerTraceAttack, cant seem to get it to work if anyone has a fix or they see an error.
