Tower battles have become a staple of the gaming world, providing endless entertainment for players of all ages. These games challenge players to strategically place towers to defend against incoming enemies, with the ultimate goal of protecting a specific area or objective. While the core concept remains the same, developers have continually innovated and improved upon the genre, incorporating new features, mechanics, and gameplay elements.
-- Tower class function Tower:new(x, y) local instance = setmetatable({}, Tower) instance.x = x instance.y = y instance.range = 100 instance.damage = 10 return instance end
-- Define tower and enemy classes local Tower = {} local Enemy = {}
function Tower:shootEnemy(enemy) -- Calculate distance to enemy local distance = math.sqrt((self.x - enemy.x) ^ 2 + (self.y - enemy.y) ^ 2)
