how to get the tail to follow the player.

Assign each tail a parent that it's following. For the first part this is the head, for the second part of the tail it's the first part, etc.

On every update, move every part of the tail to the exact location of its parent part, and then finally move the head to its new position. Make sure you start at the end of the tail when doing this, and work your way towards the head.

That should get you the effect you are looking for.

If you do it via grid, save where head went for each snake piece. If head went to the left (absolute direction) then save to grid "snake left" or whatever, etc. When you move a tail, you read that direction from a grid, erase the cell, and shift tail coordinates one cell in specified direciton.

Code: Select all

if snake.move then
  if snake.head.direction == "left" then
    map[snake.head.x][snake.head.y] = "snake left" -- record where head went
    snake.head.x = snake.head.x + 1 -- dummy for moving left
    --snake.head.y = snake.head.y
    map[snake.head.x][snake.head.y] = "snake left" -- place head to the next position
  end -- etc.
  local piece = map[snake.tail.x][snake.tail.y]
  if piece == "snake left" then
    map[snake.tail.x][snake.tail.y] = "empty"
    snake.tail.x = snake.tail.x + 1
    --snake.tail.y = snake.tail.y
  end
end

However you actually do it, you need to keep track of segments' directions.

I assign a number to each segment and I increase each by one every tick, then I check if it's higher than the snake's length and remove it if it is.

You should have a 'timer' variable and only trigger a snake update each time that variable is more than a certain value. Example:

Code: Select all

love.load = function()
   timer = 0
   timerLimit = 0.1
   --other code
end

love.update = function(dt)
   timer = timer + dt
   if timer > timerLimit then
      --update the snake, this is what I call 'tick'
   end
   --other code
end

--rest of the code
