Lua scripting Issue

[jbryan9184]

This may be noobish of me, but here is the deal.

function On_Gossip(punit, event, player)
    punit:GossipCreateMenu(100, player)
    punit:GossipMenuAddItem(player,0, "test1", 1, 0)
    punit:GossipMenuAddItem(player,0, "test2", 2, 0)
    punit:GossipSendMenu(player)
end

function Gossip_Submenus(punit, event, player, id, intid, code)
    if(intid == 1) then
        punit:SendChatMessage(12, 0, "hello1")
        player:GossipComplete()
    end
    if(intid == 2) then
        punit:SendChatMessage(12, 0, "hello2")
        player:GossipComplete()
    end
end
RegisterGossipEvent(45106, 7, "On_Gossip")(45106, 7,"Gossip_Submenus")

Have also tried:

RegisterUnitEvent(45106, 7, "On_Gossip")(45106, 7,"Gossip_Submenus")

The problem is I continually get a attempt to call global 'RegisterGossipEvent' (a nil value) with register gossip and something similar with registerunit.

Any ideas?

Are you sure you have the Lua++ LuaScripting DLL, and not the regular one?

[jbryan9184]

Not entirely sure, where can I find their svn or source for download?

[Kiyoshi]

Is there any way to compile the LUA++ LuaScripting .DLL file with AscentEmu? Also what really changes with that engine?

[TheSpidey]

Their forums: Main Page - Lua++ Forums
And yeah, you can compile it with Ascent.
Changes include, more functions, the ability to create npc gossips in lua, and probably more

[jbryan9184]

So, just to clarify. I compiled the latest LUAScripting.dll, along with all the others dlls, that comes with arcemu, as of rev 206 which was only a few days ago. Is this not the ++ version or what?

*EDIT*
I've checked the LUAengine.cpp, luafunctions.h and luaengine.h that are included with arcemu and they all have coding for gossip commands. *Stumped*

[Kiyoshi]

So all the commands stay the same? It's just added on correct?

[TheSpidey]

RegisterGossipEvent(45106, 7, "On_Gossip")(45106, 7,"Gossip_Submenus")

I'm not sure that's how it's done :P

[jbryan9184]

Well, if you have a suggestion I would love to hear it.

function On_Gossip(punit, event, player)
    punit:GossipCreateMenu(100, player, 1) --New integer added, not sure what it does exactly, but it has to do with sending the menu.
    punit:GossipMenuAddItem(0, "test1", 1, 0) --No longer need a player target.
    punit:GossipMenuAddItem(0, "test2", 2, 0)
    punit:GossipSendMenu(player)
end

function Gossip_Submenus(punit, event, player, id, intid, code)
    if(intid == 1) then
        punit:SendChatMessage(12, 0, "hello1")
        player:GossipComplete()
    end
    if(intid == 2) then
        punit:SendChatMessage(12, 0, "hello2")
        player:GossipComplete()
    end
end
RegisterUnitGossipEvent(45106, 7, "On_Gossip")
RegisterUnitGossipEvent(45106, 7,"Gossip_Submenus") --New addition "Unit".

[jbryan9184]

Bloody hell... I actually found that post before I checked back here on lua++'s forums flannel and did as it said, thank you though. Now I'm getting "Server has crashed. Reason was: a Privileged Indstruction at 0x111c0551," when the lua engine tries to load the script now. So I figured I'd recompile arcemu with the latest rev, 232 as of now, with the downloaded lua++ files in the luascripting folder. Perfect, but still getting the error. What now?

[markbatt]

try this just change the npci to match your npc you want to use.
if you want to expand further just replace the teleport location with a call to another function.

the error message you were getting is casses by the lua script not by the dll

This is a working 4 level menu

Wow, that worked perfectly. Thank you much! +rep!
