Coin = {}

function Coin:load()
self.width = 20
self.height = 20
self.speed = 200
self.x = love.math.random(0, love.graphics.getWidth() - self.width)
self.y = love.math.random(0, love.graphics.getHeight() - self.height)

end

function Coin:update(dt)

end

function Coin:draw()
love.graphics.rectangle("fill", self.x, self.y, self.width, self.height)

end

So here is my current code, and if u run this code, u can just see a white square generating randomly on random pos on the screen. My goal here is to try and make multiple generating objects at random spot and then disappearing.
If u can, please help me out, I'm quite new to Lua and coding.

Have fun with it,
The thing I'd like to point out is,
I didn't go the coin.update(), coin.draw route
Instead I just put some vanilla objects in a table

Code: Select all

local rnd = love.math.random

function love.keypressed(key)
   if key=='escape' then love.event.quit() end
end


function love.load()
   
   coins = {}
   local num_coins = 40
   for i = 1, num_coins do
      table.insert(
         coins,
         {
            x = rnd()*800,
            y = rnd()*600,
            size = 10 + rnd() * 20,
            rotate_timer = rnd(),
            rotate_speed = 2 + rnd()*8,
            alpha_timer = rnd()*2,
            color = {rnd(), rnd(), rnd()}
         }
      )
   end
   
end

function love.update(dt)
   for i = 1, #coins do
      coins[i].rotate_timer = coins[i].rotate_timer + dt * coins[i].rotate_speed
      coins[i].alpha_timer = coins[i].alpha_timer + dt
      coins[i].alpha = math.abs(math.sin(coins[i].alpha_timer))

      if (math.abs(coins[i].alpha) < 0.01 ) then
         coins[i].x = rnd()*800
         coins[i].y = rnd()*600
      end
   end
end

function love.draw()

   for i = 1, #coins do
      local c = coins[i]
      love.graphics.setColor(c.color[1],c.color[2], c.color[3], c.alpha) 
      love.graphics.ellipse(
         'fill',
         c.x, c.y,
         math.abs(math.sin(c.rotate_timer)) * c.size, c.size)
   end

end
