Multiple enemies not acting the same
« on: August 06, 2018, 06:18:11 am »
I have an enemy that creates small spheres that circle around the enemy and are thrown at the hero. However, when I have 2 enemies, only one of them will do the proper attack.

Code: ( lua) [Select]
local enemy = ...
local game = enemy:get_game()

local can_shoot = true


local sprite = nil
local nb_bats_created = 0
local nb_to_create = 0
local raintimer = nil

function enemy:on_created()
  -- Set properties.
  self:set_life(4); self:set_damage(6); self:set_hurt_style("normal")
  self:set_pushed_back_when_hurt(true); self:set_push_hero_on_sword(false)
  self:set_traversable(true)
  -- Create sprite if necessary, etc.
  sprite = self:get_sprite()
  if not sprite then sprite = self:create_sprite("enemies/more/dark/rainbow") end
  function sprite:on_animation_finished(animation)
  if animation == "looking" then sprite:set_animation("stopped") end --***
  end
  -- Start enemy.
  self:restart()
end



local function go_hero()

  local map = enemy:get_map()
  local hero = map:get_hero()

  if enemy:get_distance(hero) < 120 then

  local sprite = enemy:get_sprite()
  sprite:set_animation("walking")
  local movement = sol.movement.create("target")
  movement:set_speed(64)
  movement:start(enemy)

  else

  local sprite = enemy:get_sprite()
  sprite:set_animation("walking")
  local movement = sol.movement.create("random")
  movement:set_speed(64)
  movement:start(enemy)
  end
end




function enemy:attack()



  if jumping or attacking then
    return
  end

  if cancel_next_attack then
    cancel_next_attack = false
    return
  end

  attacking = true
  sprite:set_animation("shooting")

  local prefix = "bat" .. "_bat_"
  nb_to_create = 6

  function repeat_throw_bat()

    sol.audio.play_sound("lamp")
    nb_bats_created = nb_bats_created + 1
    local son_name = prefix .. nb_bats_created
    local son = enemy:create_enemy{
      name = son_name,
      breed = "more/dark/rainattack",
      x = 0,
      y = 0,
      layer = 0,
    }
    if math.random(6) == 1 then
      son:set_treasure("magic_flask", 1)
    end
    son:go_circle(enemy)
    local go_hero_delay = 2000 + (nb_to_create * 150)
    sol.timer.start(son, go_hero_delay, function() son:go_hero() end)

    nb_to_create = nb_to_create - 1
    if nb_to_create > 0 then
      raintimer = sol.timer.start(enemy:get_map(), 350, repeat_throw_bat)
    else
      attacking = false
      attack_scheduled = false
      if not vulnerable then
  sol.timer.start(2000, function()
go_hero()
  end)
      else
cancel_next_attack = false
      end
    end
  end
  enemy:stop_movement()
  enemy:get_sprite():set_direction(0)
  repeat_throw_bat()
end

function enemy:on_hurt()
  nb_to_create = 0
  if raintimer ~= nil then
  raintimer:stop()
  end
  enemy:get_map():remove_entities("bat" .. "_bat_")
end

function enemy:on_dying()
  nb_to_create = 0
  if raintimer ~= nil then
  raintimer:stop()
  end
  enemy:get_map():remove_entities("bat" .. "_bat_")
end

function enemy:on_restarted()

  local map = enemy:get_map()
  local hero = map:get_hero()

  go_hero()

  can_shoot = true

  sol.timer.start(enemy, 100, function()

    local hero_x, hero_y = hero:get_position()
    local x, y = enemy:get_center_position()

    if can_shoot then
if enemy:get_distance(hero) < 150 then
        attack()
        can_shoot = false
        sol.timer.start(enemy, 6666, function()
          can_shoot = true
        end)
      end
    end
    return true  -- Repeat the timer.
  end)
end

function enemy:on_movement_changed(movement)

  local direction4 = movement:get_direction4()
  local sprite = self:get_sprite()
  sprite:set_direction(direction4)
end

Some of your state variables, like 'attacking', are not local.
