Activating and Destroying Units (LUA)

[firefly2442]

I have the following debug function that doesn't seem to be working:

 

   local function debug_destroyC130()
       local c130 = Group.getByName('C-130')
       for g in pairs(c130) do
           if g:isActive() == false then
               g:activate()
           end
           --there's no setLife() method ... :/
           --I don't think destroy() does what we want
           trigger.action.explosion(g:getPosition().p, 100) 
       end
   end

And here's the error message:

 

attempt to call method 'isActive' (a nil value)

Am I not iterating through the group properly?

[Grimes]

isActive is available to the unit class, not group. This always trips me up.

 

And no you aren't iterating the group correctly.

 

for i, u in pairs (c130:getUnits()) do

 

i is the index and u is the unit object.

Since we don't have a Group.isActive() function in LUA, what would be a good way of determining whether a group has been activated?

 

I was looking at maybe getting one of the units in the group, and checking whether the unit is active using Unit.isActive(). If so, that would imply the group is active. I just wanted to see if there might be a more straightforward (easier) way.

 

Thanks!

If there is at least one unit in the group that is returned from Group.getUnits(), the group can be considered alive/active.

local group = Group.getByName("someGroupName")
if group and #group:getUnits() > 0 then
 -- group is alive/active
end

I have not tried this particular scenario to test for isActive, but I would think that non-active units would not be returned, nor even the group. I hope that I am not mistaken. I am unable to test this right now.
