Lua Help me learn lua

Core_ · Jul 22, 2011

Well, i thought i need to learn lua, i find it kinda easy, but there are some things i just cant understand or i cant make them work, so i hope you can help me with my doubts.

_______________________________

What CID means?

Like here:
function onStepIn(cid, item, pos, fromPos), i think all that stuff (cid, item, pos~) its what the script calls right? like the script will use a item, a position etc.... but what cid means? my first guess is like creature id (the player that use the script).
_______________________________

Ok, so i'm making this script, when you step in a tile you'll be teleported to another tile (i dont want to use tp's thanks), i'll use it just in a few parts of the map like shortcuts in the city....

So thats my script

LUA:

function onStepIn(cid, pos, fromPos)
        doTeleportPlayer(cid,1025,985,7,CONST_ME_ENERGYAREA) 
        return false
end

I'ts not working on the latest 0.4....

i wish some one can tell me why, maybe doTeleportPlayer is no longer supported... but i couldnt find another function for teleport

thats all for now i hope you can help me with this basic things.

lmao, first of all instead of 1025, 985, 7 use {x=1025, y=985, z=7}
and the CONST_ME_ENERGYAREA
should be on
doSendMagicEffect(getPlayerPosition(cid), CONST_ME_ENERGYAREA)
so it would be like

LUA:

function onSetpIn(cid, item, pos, fromPos)
        doTeleportThing(cid,{x=1025, y=985, z=7})
        doSendMagicEffect(getPlayerPosition(cid), CONST_ME_ENERGYAREA)
        return TRUE
end

Code:

local place = {x= 95, y= 117, z= 7}
function onStepIn(cid, item, pos, fromPos)
		doTeleportThing(cid, place) 
			doSendMagicEffect(place, CONST_ME_ENERGYAREA)
			end

there you can learn some lua

ok, the cid thing in doTeleportThing means it will teleport the player?

bogart your script is fail

uchiha1sasukee · Jul 22, 2011

try this

Code:

function onStepIn(cid, item, fromPosition, itemEx, toPosition)
        doTeleportPlayer(cid,1025,985,7,CONST_ME_ENERGYAREA) 
        return false
end

yes

Evil Puncker · Jul 22, 2011

btw cid = creature ID in this case I think

ahmed30 · Jul 22, 2011

@uchiha1sasukee
your script is fail too

Core_ · Jul 22, 2011

already learn something thanks guys!
another noobie thing
<movevent type="StepIn" itemid="3196" event="script" value="custom/shortcuttp.lua"/>
if i put like actionid instead of itemid and i set a action id to a normal tile will it work?

broken script, enjoy errors

Remember! Always Test! before posting! That's a must on learning LUA

uchiha1sasukee · Jul 22, 2011

thanks for the advice Apollo appreciate it

Core_ · Jul 23, 2011

Mmmm the last script worked fine but i had to make 2, 1 for go from x pos to y pos and another one to go from y pos to x pos, so i tried to make it in only one script.

But no success

i just suck in this D:

LUA:

local config = {
	temple =
	{
		{x = 1005, y = 999, z = 7}
	},
	temple1 =
	{
		{x = 1006, y = 999, z = 7}
	},
	shops =
	{
		{x = 1024, y = 985, z = 7}
	},
	shops1 =
	{
		{x = 1025, y = 985, z = 7}
	}
}
function onStepIn(cid, item, pos, fromPos)
	if getThingPos(cid) == temple then 
		doTeleportThing(cid, shops1) 
		doSendMagicEffect(cid, CONST_ME_MAGIC_GREEN)
elseif getThingPos(cid) == shops then
		doTeleportThing(cid, temple1) 
		doSendMagicEffect(cid, CONST_ME_MAGIC_GREEN)
end
	end

idk wats wrong with it :s maybe some function or something but idont get any error in the console..
also i had to make shops and shops1, idk how to make it like doTeleportThing(cid, shops {x + 1}) or something like that D:

your script is not written incorrectly, it just contains logic errors, think about what you want it to do and what you just told it to do - it doesn't match up. These kinds of errors are the aggravating and frustrating ones you'll run into, so learn how to overcome them

Cykotitan · Jul 23, 2011

Besides you cant even compare tables like that. use doComparePositions

You know what i mean?

How does it work?

where do i find those functions i'm trying to do it like, if tileid = xx then tp to shops ...... but i cant find a function for that D:
getTileItemById(pos, itemId[, subType = -1])
getTileItemByType(pos, type)
getTileThingByPos(pos)
getTileInfo(pos)
would one of those help?

VirrageS · Jul 23, 2011

If you are using

LUA:

function onStepIn(cid, item, pos, fromPos)

You can get tile id by:

Code:

function onStepIn(cid, [COLOR="#FF0000"]item[/COLOR], pos, fromPos)
	if [COLOR="#FF0000"]item[/COLOR].itemid == 6458 then	
		............
		............

Thanks! works now, now i got 2 options this one or 2scripts in one i guess is best only one.

LUA:

local temple = {x = 1006, y = 999, z = 7}
shops = {x = 1025, y = 985, z = 7}
function onStepIn(cid, item, pos, fromPos)
	if item.itemid == 3188 then
		doTeleportThing(cid, shops) 
		doSendMagicEffect(shops, CONST_ME_MAGIC_GREEN)
	elseif item.itemid == 3196 then 
		doTeleportThing(cid, temple) 
		doSendMagicEffect(temple, CONST_ME_MAGIC_GREEN)
	end
	end

or 2 of this

LUA:

local place = {x= 1006, y= 999, z= 7}
function onStepIn(cid, item, pos, fromPos)
		doTeleportThing(cid, place) 
			doSendMagicEffect(place, CONST_ME_MAGIC_GREEN)
end
