Hi everyone,

I'm dipping my toes into Lua a bit and tried to produce a random location start. Finally I got something to work: 3 preset zones. Somewhere in there my unit will spawn.

My question: how would you have solved this problem?

The zones and the unit are given. Randomly choose a starting position in these zones.

All the best

Here the Lua part:

Code: Select all

local MySide = VP_GetSide({name = "Friendly"})
local MyZone1 = MySide:getstandardzone("Zone1")
local MyZone2 = MySide:getstandardzone("Zone2")
local MyZone3 = MySide:getstandardzone("Zone3")

 --choosing the zone
math.randomseed(os.time())
local r = math.random(1,3)
if r == 1 then
    RandomZone = MyZone1
elseif r == 2 then
    RandomZone = MyZone2
elseif r == 3 then
    RandomZone = MyZone3
end

--getting Latitude RPs
local Latitude = {}
for i = 1, 4 do
    Latitude[i] = RandomZone.area[i].latitude
end

--finding max Latitude RP
local LatitudeMax = math.mininteger
for i, v in ipairs(Latitude) do
    if Latitude[i] > LatitudeMax then
        LatitudeMax = Latitude[i]
    end
end

--finding min Latitude RP
local LatitudeMin = math.maxinteger
for i, v in ipairs(Latitude) do
    if Latitude[i] < LatitudeMin then
        LatitudeMin = Latitude[i]
    end
end

--getting Longitude RPs
local Longitude = {}
for i = 1, 4 do
    Longitude[i] = RandomZone.area[i].longitude
end

--finding max Longitude RP
local LongitudeMax = math.mininteger
for i, v in ipairs(Longitude) do
    if Longitude[i] > LongitudeMax then
        LongitudeMax = Longitude[i]
    end
end

--finding min Longitude RP
local LongitudeMin = math.maxinteger
for i, v in ipairs(Longitude) do
    if Longitude[i] < LongitudeMin then
        LongitudeMin = Longitude[i]
    end
end

--spawning ship
SpawnLatitude = math.random() * (LatitudeMax - LatitudeMin) + LatitudeMin
SpawnLongitude = math.random() * (LongitudeMax - LongitudeMin) + LongitudeMin

local MyShip = ScenEdit_AddUnit({type = "Ship", name = "Random Spawn", side = "Friendly", dbid = 3889, lat = SpawnLatitude, long = SpawnLongitude})
