LÖVE

What would be the approach to accomplish the following:

I have a button and a sprite with two movements. The attack movement and the idle movement. The sprite is always being animated with the idle movement. When I click the button, I want to change the animation to the attack one and when finishing the attack, return to the idle animation.
Also, is possible to get the exact moment of the end of the attack to trigger another event?


Thanks for any answer, I'm really new into Löve and Lua.

animation.onLoop = function () -- do something end

function Player.new()
  local self = {} -- whatever you are doing here
  
  self.idle     = IDLE_ANIM:clone() -- the anim8 idle animation
  self.attack = ATTACK_ANIM:clone()
  self.attack.onLoop = function () self:attackDone() end
  self.anim   = self.idle

  return self
end

function Player:update(dt)
  self.anim:update(dt)
  
  if not self.attacking and love.keyboard.isDown" " then
    self.attacking = true
    self.anim = self.attack
  end
end

function Player:draw()
   self.anim:draw()
end

function Player:attackDone()
  -- do something
end

onLoop is an optional parameter which can be a function or a string representing one of the animation methods. It does nothing by default. If specified, it will be called every time an animation "loops". It will have two parameters: the animation instance, and how many loops have been elapsed. The most usual value (apart from none) is the string 'pauseAtEnd'. It will make the animation loop once and then pause and stop on the last frame.

slashAnim = anim8.newAnimation(animgrid('1-6',1), 0.04, (function(a,b) DRAWSLASH=false  a:pauseAtEnd() end))
