Tomb Raider - code help - what are functions - lua default code for level

The overview should say:

It’s time to fill in the body of a function and use it to make your code nice and clean!

Remember that a parameter is just a way of passing information into a standalone function. It is a predefined variable containing whatever was when between the () when the function was called.

‘Calling’ a function is when the code is actually peformed. See the examples below as to how functions are called:

-- This is 'defining' a function:
local moveUpAndDown = function()
    hero:moveUp() -- This is calling the 'moveUp' function.
    hero:moveDown() -- This is calling the 'moveDown' function.
end

hero:say("I'm saying something!") --This is 'calling' the 'say' method.
moveUpAndDown() -- This is 'calling' the custom defined 'moveUpAndDown' method.

Just use the target like you would any variable!

local checkAndDefend = function(target)
    if target then
        hero:say("I see an enemy! I should beat them up.")
    end
end

The intro should say

Remember that a parameter is a way of passing information into a function. It is a predefined variable of whatever the argument is when called!

local checkAndEat = function(target)
    if target.type == "fruit" then
        hero:eat(target)
    else
        hero:toss(target)
    end
end

while true do
    hero:moveUp()
    local nearestTree = hero:findNearestTree()
    local food = hero:harvest(nearestTree)
    checkAndEat(food)
end

And the following default code block should have been provided:

-- A forgotten tomb in the forest!
-- But the ogres are hot on your heels.
-- Break open the tomb, while defending yourself from the munchkins.

-- This function should attack an enemy if it exists, otherwise attack the door!
local checkToDefend = function(target)
    -- Check if the target exists
    
        -- If so, attack the target
        
    -- Use an else to do something if there is no target
    
        -- Otherwise attack the "Door"
   
     
end

while true do
    local enemy = hero:findNearestEnemy()
    checkToDefend(enemy)
end

does this help now?
