Hit and Freeze

```lua -- You are trapped. Dont move, it ll be painful. -- Attack ogres only when they re within reach.

– This function checks if the enemy is in your attack range.
– The function returns a boolean value: true or false
local inAttackRange = function(enemy)
local distance = hero:distanceTo(enemy)
– Almost all swords have attack range of 3.
if distance <= 3 then
return true
else
return false
end
end

while true do
– Find the nearest enemy and store it in a variable.

-- Call inAttackRange(enemy), with the enemy as the argument
-- and save the result in the variable canAttack.

-- If the result stored in canAttack is true, then attack!

end

Introduction:

You're caught in a trap! 
Wait until the ogres are close, then attack, or you'll injure yourself!

Functions can return a value, including a `boolean` value (true or false).

Use this to decide if an ogre is `inAttackRange()`!

```lua
local inAttackRange = function(enemy)
    local distance = hero:distanceTo(enemy)
    if distance <= 3 then
        -- return True because the enemy is in range
    else
        -- return False because the enemy is out of range
    end
end

Save the result to a variable to use it later in the code:

local canAttack = inAttackRange(target)
Overview:

You can have several return statements in a function, but only one will be used, because return causes the function to stop executing, and “returns” back to where the function was called.

local moreThanTen = function(n)
    -- if 'n' greater than 10, then the function will return true.
    if n > 10 then
        return true
    -- Otherwise 'return' inside 'else' will be called and the function will return false.
    else
        return false
    end
end

local isSmall = moreThanTen(5) -- isSmall == true
