So I was trying to make a test element that has an index in a lua list, but the problem is that when the element is destroyed it is supposed to remove its entry from the list. However, I could find no way of letting me do this on the wiki(or just didn't look closely enough) so I have come to ask for a function that does this or to request a new function.

NEVERMIND- I fixed it.

For some reason it becomes very laggy when using ChangeType and used to even crash TPT(doesn't do that anymore)

Here's my code:

local listi = {}
local listx = {}
local listy = {}
elem.property(test,"Create", function(i,x,y,s,n)
table.insert(listi,i)
table.insert(listx,x)
table.insert(listy,y)
end
elem.property(test,"ChangeType", function(i,x,y,t,n)
if n ~= test then
print("works?")
table.remove(listi,i);
table.remove(listx,i);
table.remove(listy,i);
listi[i] = nil;
listx[i] = nil;
listy[i] = nil;
print(listi[i])
end
end)

in theory it should remove the index from the table but for whatever reason it does not and lags the game while creating BHOL(the update function that does this is here:

if listi[i] then

 local xog = listx[i]
local yog = listy[i]
sim.partProperty(i,sim.FIELD_X,xog)
 sim.partProperty(i,sim.FIELD_Y,yog)
end
