LUA Player Cast Spell

[Bapesy]

Hello, how can I make a player cast a spell in gossip lua, I have teleporter working but can't figure out how to make a player cast a spell. Also how would I set it so if alliance view the teleporter it would be different from horde? ie: Horde Cities & Alliance Cities.

Thanks,

Five Gum!

Use the (You have to have LUA++)
if(unit:GetFaction()) = ally faction 1 or 2 or 3 or 4 or 5 then
Gossip Menus here

And what do you mean by cast a spell? Like teleportation? If so, use unit:TeleportUnit

[Bapesy]

No like cast a buff on the player. Also were does the faction id go in there? In between the ())?

No, just use the setup I have.

Anyways, it would be like
Unit:GetClosestPlayer()
Unit:CastSpellOnTarget(player, spell)

I'm writing a LUA .pdf guide thats 20 pages long soon so just wait for that for more complex stuff

[Bapesy]

Unit:GetClosestPlayer()
Unit:CastSpellOnTarget(player, spell)

Can that be done with OpenAscent lua?

No, you need LUA++'s LUAscripting.cpp LUAscripting.h and LUAengine.cpp (or .h can't remember)

Edit- Now you can, they merged

Alright, and what about if the player is in combat than It'll broadcast message and if hes not then It'll do the function?

Edit: You can do all the things you said or just cast spell?

All the things I said.

I'm not sure if combat checks are supported in LUA, but I may be able to create a semi-working one.

if(unit:IsPlayer = true)(unit:GetHealthPct() = 100)then
Stuff here

That would work if the player had 100% meaning not in combat. Of course if he wasn't in combat and had 90% health then it wouldn't work. But thats a makeshift function

Here is the little script and I got this error - calling 'CastSpellOnTarget' on bad self (number expected, got userdata)

function warp_on_gossip_talk3(unit, event, player)
unit:GossipCreateMenu(3543, player)
unit:GossipMenuAddItem(player, 5, "Remove Resurrection Sickness", 1, 0)
unit:GossipMenuAddItem(player, 5, "Mall", 2, 0)
unit:GossipSendMenu(player)
end

function warp_on_gossip_select3(unit, event, player, id, intid, code)
 
if(intid == 1) then
player:LearnSpell(15007)
player:UnlearnSpell(15007)
unit:SendChatMessage(12,0, "Resurrection Sickness has been removed from you.")
end

if(intid == 2) then
unit:GetClosestPlayer()
unit:CastSpellOnTarget(player, 29562)
end

intid = 0
end
 
RegisterGossipEvent(45403 , 1, "warp_on_gossip_talk3")
RegisterGossipEvent(45403 , 2, "warp_on_gossip_select3")

[SectorSeven]

Yeah the error is at the line
unit:CastSpellOnTarget(player, 29562)

not sure what it was though. I believe you can't use player function with that statement.

[Bapesy]

This is how it should look right -

function warp_on_gossip_talk3(unit, event, player)
if (unit:GetHealthPct() > 100)then
if(unit:GetFaction()) = ally faction 1 or 2 or 3 or 4 or 5 then

unit:GossipCreateMenu(3543, player)
unit:GossipMenuAddItem(player, 5, "Remove Resurrection Sickness", 1, 0)
unit:GossipMenuAddItem(player, 5, "Mall", 2, 0)
unit:GossipSendMenu(player)

else

unit:SendChatMessage(12,0, "You are below 100% health, regenerate back to 100% to continue.")
   end
end

function warp_on_gossip_select3(unit, event, player, id, intid, code)
 
if(intid == 1) then
player:LearnSpell(15007)
player:UnlearnSpell(15007)
unit:SendChatMessage(12,0, "Resurrection Sickness has been removed from you.")
end

if(intid == 2) then
unit:GetClosestPlayer()
unit:CastSpellOnTarget(player, 29562)
end

intid = 0
end
 
RegisterGossipEvent(45403 , 1, "warp_on_gossip_talk3")
RegisterGossipEvent(45403 , 2, "warp_on_gossip_select3")

Edit: What would it be if I just wanted a certain class to see it? GetClass = 2?

unit:GetClosestPlayer()

^ Why are you calling this?
