-- @return the weapon object created

--an example function that will be common to all Weapons
-- Called when the weapon begins colliding with another node
-- @return nil
function Weapon:collide(node, dt, mtv_x, mtv_y)

--This is a snippet of a Mallet file

function Mallet.new(node, collider, plyr, malletItem)
    local mallet = {}
    setmetatable(mallet, Mallet)
    mallet = Weapon.addWeaponMethods(mallet)

    --a few key are set..

    return mallet
end




--The function essentially treats Mallet as a subclass of Weapon and only accesses the parent class's methods if it doesn't have one by the same name
