lua KeyValue Problem

OK, this is definitely me being stupid, but I can't figure out how to make this work for the life of me. I'm trying to set this up so that the first helicopter trip drops units off, and the second trip picks them back up, using keyvalue to keep track of the state.
Code: Select all
val = ScenEdit_GetKeyValue('LZ')
if val == 0
ScenEdit_AddFacility('Test', 'Landing Zone', 248, 0 , 'DEC', '11.1973239792203', '49.0965833574316')
ScenEdit_SetKeyValue('LZ', '1')
if val == 1
ScenEdit_DeleteUnit({side="Test", name="Landing Zone"})
ScenEdit_SetKeyValue('LZ', '0')
end
The event is firing...and the individual actions are working through the console...so I know that the problem is how I've implemented the keyvalue. Any help?

Should the second "if" be an "elseif"?
I'm not very familiar with lua yet, but in many other languages an "if" statement can only be followed by an "else", "elseif", or "end" statement.

Quite right! I'd recommend making sure that val is set to a value, if its the first time GetKeyValue is called on 'LZ' it might be blank. Also note that GetKeyValue will always return a string:
This might work:
val = ScenEdit_GetKeyValue('LZ')
if val == nil or val == ''
val = '0'
end
if val == '0'
ScenEdit_AddFacility('Test', 'Landing Zone', 248, 0 , 'DEC', '11.1973239792203', '49.0965833574316')
ScenEdit_SetKeyValue('LZ', '1')
end
if val == '1'
ScenEdit_DeleteUnit({side="Test", name="Landing Zone"})
ScenEdit_SetKeyValue('LZ', '0')
end

No joy on that one baloogan...the event is firing, but nothing happens. I have ensured that the keyvalue is set using the console before it first fires. The individual events fire, but I can't seem to get it to work with the if/ifelse option.

Isn't the proper syntax in Lua like this?
if COND then
BLOCK
elseif COND then
BLOCK
...
else
BLOCK
end
It seems that then keyword is missing from both examples.
