A Few Questions :)> Update Methods

[OS]

Hello all. I would like to know some things about the update method.

1.) Does an Update Method occur every second or every frame? I believe it is every frame, but I just want to be sure.

2.) If I call update within update, does it affect the speed at which the code runs? I mean, look at this code:

def initialize
   @a = 5
end

def update
  if @bool == true
    @a = 20
    @bool = false
  end
  
  if @a <= 10
    @bool = true
    update
  end

  operations
end

Assume that @a was defined earlier as 0. update is called so that operations won't run unless @a > 10. Does this work without taking an extra frame or second? I guess this is silly to ask, but I was just curious.

Peace!

1) Once every frame.

2) If you call a method within itself, you create an infinite loop... won't get you anything besides a stucked game ^_^ Use this code instead:

def initialize
   @a = 5
end

def update
  if @bool == true
    @a = 20
    @bool = false
  end
  
  loop do
    if @a <= 10
      @bool = true
  #else
  #  @a -= 1  
    end
  end

  operations
end

The substract method confuses me a little and doesn't seem to be any practical, but I kept it... I also added two lines you didn't had, to decrease the variable @a, because you wouldn't get nowhere if you didn't change the value of that integer ^_^

The update method is just a method often called for objects that need to do something every frame (check if a button is pressed, movement, etc.).

It's all a matter of personal prefrence really.

@Bluescope: ???? Please look at the code. Update is called within itself ONLY if certain values are true or false. It won't be called again in the second iteration of the update method.

This kinda answers my questions. I'll just assume I can continue with my scripting for now. If I get errors, then I'll know for sure!

Peace!
