[Lua] OnEvent() Help

Postby Ace Rimmer » Tue Feb 23, 2010 5:34 pm

I'm trying to work out what to do with 'unitType', or rather how to use it properly.

Code: Select all

function OnEvent(eventType, sourceID, targetID, unitType, longitude, latitude)
   if (eventType == "Destroyed") then
      SendChat(tostring(sourceID:GetUnitType()) .. " killed a " .. unitType .. " " .. tostring(targetID:GetUnitType()))
....
end


This

Code: Select all

SendChat(tostring(sourceID:GetUnitType()) .. " killed a " .. unitType

outputs "Gunshot killed a Invalid"

while this

Code: Select all

SendChat(tostring(sourceID:GetUnitType()) .. " killed a " .. tostring(targetID:GetUnitType()))

outputs "Gunshot killed a Fighter"

What's up with unitType (not GetUnitType)? 'Invalid' isn't a normal Lua error, (e.g. 'trying to index a nil value', 'expected string got userdata') so I'm lost.

The documentation says that "Invalid" is a unit type, it looks like this is a bug, for now I would stick with using targetID:GetUnitType() which seems to get the result you want.
GENERATION 22:The first time you see this, copy it into your sig on any forum and add 1 to the generation. Social experiment.

Wow, I missed the "Invalid" type. :P

Sent this through:

Mailing list wrote:I'm curious to whether or not this is an intended output (and perhaps if unitType "Invalid" is only for events such as CeaseFire, Votes, ect)?

function OnEvent(eventType, sourceID, targetID, unitType, longitude, latitude)
if (eventType == "Destroyed") then

This SendChat(tostring(sourceID:GetUnitType()) .. " killed a " .. unitType) outputs "Gunshot killed a Invalid"
This SendChat(tostring(sourceID:GetUnitType()) .. " killed a " .. tostring(targetID:GetUnitType())) outputs "Gunshot killed a Fighter"
