Posted: Wed Mar 20, 2019 10:40 pm Post subject: Trouble Setting memrec.OnActivate

Hello,
I'm trying to make a script that only allows one of its children to be activated at a time. I'm running into trouble as soon as I set the child scripts' OnActivate() functions.

Code:

[ENABLE]
{$lua}
if syntaxcheck then return end
--memrec.OnActivate = function(record, before, currentstate) end
if memrec.Count then
print(tostring(memrec.Count))
--print("---")
local thisParent = memrec
for i = 0,thisParent.Count do
--print(tostring(memrec.Child[i].Active))
if thisParent.Child[i].OnActivate ~= thisParent then
thisParent.Child[i].OnActivate =
function(record, before, currentstate)
--print(tostring(~memrec.Child[i].Active))
--if syntaxcheck then return end
--local parent = thisParent
--for j = 0,thisParent.Count do
-- if thisParent.Child[j] ~= thisParent.Child[i] then
-- thisParent.Child[j].Active = false
-- end
--end
end
--print(tostring(memrec.Child[i].OnActivate))
--print("---")
end
end
end
--memrec.OnActivate = function(record, before, currentstate) end

{$asm}
[DISABLE]
{$lua}
if syntaxcheck then return end

What I'm trying to do is make it so that each child's OnActivate sets every other child's Active to false. As soon as I uncomment the code that sets Child[i].OnActivate, the parent script starts instantly deactivating itself as soon as I activate it. I added a check to make sure I wasn't setting the parent script's OnActivate somehow but it had no effect.

Any help would be greatly appreciated.

Code:

if thisParent.Child[i].OnActivate ~= thisParent then

OnActivate is a function and thisParent is a memoryrecord object

Code:

for i = 0,thisParent.Count do

should go to thisParent.Count-1 (same for the j loop)

OnActivate must return true/false depending on if you wish to allow the activation (it gets called twice, once before and once after. In the before you can control that)

Code:

[ENABLE]
{$lua}
if syntaxcheck then return end
--memrec.OnActivate = function(record, before, currentstate) end
if memrec.Count then
local thisParent = memrec
for i = 0,thisParent.Count-1 do
--print(tostring(memrec.Child[i].Active))
if thisParent.Child[i].OnActivate ~= thisParent then
thisParent.Child[i].OnActivate = function(record, before, currentstate)
local parent = thisParent

if currentstate==false then --before it gets activated
for j = 0,thisParent.Count-1 do
local mr=thisParent.Child[j]
if thisParent.Child[j] ~= record then
thisParent.Child[j].Active = false
end
end
end

return true --allow
end
end
end
end
{$asm}

[DISABLE]
{$lua}
if syntaxcheck then return end

This is what I was missing, thanks a bunch!
