-- Hedgewars Bazooka Training

-- Scripting Example

-- Lines such as this one are comments - they are ignored

-- by the game, no matter what kind of text is in there.

-- It's also possible to place a comment after some real

-- instruction as you see below. In short, everything

-- following "--" is ignored.

---------------------------------------------------------------

-- At first we implement the localization library using loadfile.

-- This allows us to localize strings without needing to think

-- about translations.

-- We can use the function loc(text) to localize a string.

HedgewarsScriptLoad("/Scripts/Locale.lua")

-- This variable will hold the number of destroyed targets.

local score = 0

-- This variable represents the number of targets to destroy.

local score_goal = 5

-- This variable controls how many milliseconds/ticks we'd

-- like to wait before we end the round once all targets

-- have been destroyed.

local end_timer = 1000 -- 1000 ms = 1 s

-- This variable is set to true if the game is lost (i.e.

-- time runs out).

local game_lost = false

-- This variable will point to the hog's gear

local player = nil

-- This variable will grab the time left at the end of the round

-- This is a custom function to make it easier to

-- spawn more targets with just one line of code

-- You may define as many custom functions as you

-- like.

-- This function is called before the game loads its
