Addon Help, LUA Programming

[BizenDk]

well.. Attemp to call global (a nil value) i don't know WoW Lua, i am coding for gmod :) BUT it's for sure you have a nil value somewhere nil = nothing.. simply when something dosen't exist :) good luck scripting it would be helpfull if you showed the code

[Bitwzyze]

The problem is that you don't have a handler for the click event registered.

[randomWonders]

the problem is not so much in the code here but in the fact that in order to follow some body you have to be in a group with them. (i know this is an old video but someone may have the same type of issue some time.)

@randomWonders You're an idiot.

what addon is this

[cloudstrife602]

you can read the book that i have found immensely helpful. World of Warcraft Programming. find it at wowprogramming com/store. i did find a 'cheaper' method of acquiring the book but i cant share that here... perhaps you'll be able to find it also

First problem: its follow instead of fallow

[wannaweed45]

You have two different ON_CLICK options, that may be one of your problems another thing I see /f you should have the whole command there

Finished..

[NeffiStar]

local f = CreateFrame('Button','MyButton­',UIParent)

f:SetScript('OnClick',function­() if UnitExists('target') then FollowUnit('target') end

end)

-- Asign properties of the button afterwards and enjoy

i'm looking too for some wow lua tutors ... :( btw nice song <3

[sonicminneapolis]

Use nil and then goes on the same line of the if...

[jackprince1983]

do it like this ...

---

function Button1_OnClick()

if (event == "PLAYER_TARGET)

 then FollowUnit("target")

else message ("You have no target to follow");

end

---

you also seem to have an error in your onclick function. So the code isn't even parsed to the

also false "/f"

he did not ask for a makro he did ask for lua code, maybe this is just the beginning
