How to make a table interact with the same table?

[Jomkin]

Hello,

I have this table.

Code: Select all

monsters = {}

function newMonster(x,y)

monster = {}
monster.x = x
monster.y = y
monster.style = "green"
monster.removed = false
table.insert(monsters, monster)

end

How can I interact in the update like if I want to the monster.style "green" to follow the monster.style "blue"?

Thank you!

How does a style follow another style? I don't understand the question.

How does a style follow another style? I don't understand the question.

When I was talking about following I meaned :

Code: Select all

if monster.x (the blue one) > monster.x (the green one) then
monster.x = monster.x + monster.speed * dt (the green one)
end

Oh OK, thanks for the clarification. Well, if you're sure that the table will only contain 1 blue monster, you could do this:

Code: Select all

local blue_monster
local monster
-- Loop to find the blue monster
for i = 1, #monsters do
  monster = monsters[i]
  if monster.style == "blue" then
    blue_monster = monster
    break
  end
end
assert(blue_monster, "There's no blue monster in the monsters table")
-- Loop to make all green monsters go right when the blue monster is to their right
for i = 1, #monsters do
  monster = monsters[i]
  if monster.style == "green" then
    if blue_monster.x > monster.x then
      monster.x = monster.x + monster.speed * dt
    end
  end
end

But if there's only one blue monster, then it's better to store it in a variable when you create it, instead of having to loop to look for it.
