Weapon.getTarget() isnt working

[SubVision]

I tried make script that writes a message when rocket are approaching to players plane.

To do this i tried to use function Weapon.getTarget(), when rocket were flying to aircraft. This returned nil, but missile were aiming at plane(there were no other weapons).

 

Code:

local unit=Group.getByName(env.getValueDictByKey(group.name)):getUnits()[1]

local foundWpns = {}

local volS = {

id = world.VolumeType.SPHERE,

params = {

point = unit:getPoint(),

radius = 5000

}

}

local ifFound = function(foundItem, val)

foundWpns[#foundWpns + 1] = foundItem

return true

end

 

world.searchObjects(Object.Category.WEAPON, volS, ifFound)

 

return foundWpns[1]:getTarget()
