isInArray

How to use isInArray?

 

[Colandus]

table = {"First", "Second", "Third"}
check = isInArray(table, "Second")
check2 = isInArray(table, "NotIn")
print(check, check2)

Try that piece of code
It simply returns 1 if that is in the array, but if it's not in the array, I think it returns -1, check the script and see by yourself...

Although, it doesn't take spaces, if you'd check like "Hello mr", I THINK it'd only check "Hello", or nothing at all, not sure. But you could make your own function for this:

-- Function by Colandus
function isInArray(t, v, c)
	v = (c ~= nil and string.lower(v)) or v
	if type(t) == "table" and v ~= nil then
		for key, value in pairs(t) do
			value = (c ~= nil and string.lower(value)) or value
			if v == value then
				return 1
			end
		end
	end
	return -1
end

This one works exactly the same, but only that in NORMAL isInArray, it's case-sensetive, which means:

table = {"First", "Second", "Third"}
check = isInArray(table, "Second")
check2 = isInArray(table, "THIRD")
print(check, check2)

Would print -1 -1, even though Third is in the array, but THIRD is not in. But my function, will allow incase-sensetivity if you just write something at the last parameter:

-- Using my isInArray (in global.lua)
table = {"First", "Second", "Third", "4th Fourth"}
check = isInArray(table, "4th Fourth")
check2 = isInArray(table, "THIRD", true)
print(check, check2)

This will print 1 1, because spaces does work and incase-sensitivity was on at the second check.

this work?

tilex = {120, 121, 122, 123, 124, 125, 126, 127, 128, 129}
tiley = {32, 33, 34, 35, 36, 37, 38, 39}
tilez = {9}

if (isInArray(tilex, getPlayerPosition(cid).x) == TRUE) and (isInArray(tiley, getPlayerPosition(cid).y) == TRUE) and (isInArray(tilez, getPlayerPosition(cid).z) == TRUE) and getCreatureHealth(cid) < 1 then
arena = TRUE
else
arena = FALSE
end

Well... The isInArray part will work, but what's TRUE? Is it 1? Check in global.lua if it's 1

Also, "and getCreatureHealth(cid) < 1", that's impossible, so it'll always return "FALSE" for the "arena" variable.

A slighter way would be to use a loop for this check instead.

local position = {fromx=120, fromy=32, tox=129, toy=39, z=9}
 
function onUse(cid, item, frompos, item2, topos)
	for i = position.fromx, position.tox do
		for j = position.fromy, position.toy do
			local pos = {x=i, y=j, z=position.z, stackpos=253}
			local getThing = getThingfromPos(pos).uid
			if isPlayer(getThing) == 1 then
				//Player found, return a value to break the loop.
			end
		end
	end
	return FALSE
end

True = 1
False = 0

 

[Colandus]

You got that from global.lua?

Was it:
True = 1
False = 0

or:
TRUE = 1
FALSE = 0
