Is it possible make a NPC target entities with a prefix?

Code: ( lua) [Select]

target_movement:set_target(map:get_entities("bird_"))

Well a movement can only have one direction at a time, so you have to choose a target.
You can always make a loop to detect the closest entity from a list of entities, and repeat this in a timer.

How is that done? My script looks like this so far.

Code: ( lua) [Select]

-- Call a function every second.
sol.timer.start(5000, function()
    local birds = map:get_entities("bird_")
    local npc_near_birds = npc_1:get_distance(birds)
    if npc_near_birds < 10 then
       movement = sol.movement.create("target")
       movement:set_target(birds)
       movement:set_speed(48)
       movement:start(npc_1)
    end
  return true  -- To call the timer again (with the same delay).
end)

Can anyone give me an example? Please...

I think the best example would be the "Evil Tile".  these are the tiles in dungeons that lift up and fly at the hero, one at a time, with a timed delay between each tile's movements.

Do you know what map and game the "Evil Tile" exists in?

Edit:
Found it.
