-- Hedgewars Shotgun 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 put all text we'd like to use in some arrays.

-- This way we're able to localize the text to be shown without

-- modifying other files.

-- The language to be used is stored in the global variable

-- 'L' that is set by the game (string).

-- Text may then be accessed using "arrayname[L]".

local caption = {

	["en"] = "Bazooka Training",

	["de"] = "Bazooka-Training"

	-- To add other languages, just add lines similar to the

	-- existing ones - don't forget the trailing ","!

	}

	["en"] = "Aiming Practice",

	["de"] = "Zielübung"

	}

	["en"] = "Eliminate all targets before your time runs out.|You have unlimited ammo for this mission.",

	["de"] = "Eliminiere alle Ziele bevor die Zeit ausläuft.|Du hast in dieser Mission unbegrenzte Munition."

	}

local timeout = {

	["en"] = "Oh no! Time's up! Just try again.",

	["de"] = "Oh nein! Die Zeit ist um! Versuche es nochmal."

	}

local success = {

	["en"] = "Congratulations! You've eliminated all targets|within the allowed time frame.",

	["de"] = "Gratulation! Du hast alle Ziele innerhalb der|verfügbaren Zeit ausgeschaltet."

	}

	["en"] = "Shotgun Team",

	["de"] = "Die Knalltüten"

	}

	["de"] = "Jäger"

	}

-- To handle missing texts we define a small wrapper function that

-- we'll use to retrieve text.
