my widget uses timeX object. im pretty sure its mmf independant. its as accurate as your computers clock.

The whole point of designing your own internal timer is to avoid being in sync with the computer clock. If you want to be in sync with the computer clock, just use the timer options in MMF2 itself. However if you're trying to create a game that depends on it's own internal values to keep track of everything, that's when you need an internal loop of your own.

brandon who said anything about being synced with the computers clock? when you start a timeX objects clock it keeps accurate time in milliseconds until you stop it. it still follows the rules of pausing when the app is minimized, being moved, or resized, unless you specify in the application settings. if you base it completely internally its going to end up being inaccurate to some degree. defeating the purpose of a clock in the first place.

Hernan can I get an example of how this would work in MMF?(doesn't have to be an MFA.)

Do I need to? It's dead easy ._. You only need to create 1 event!
Create 4 counters, let's call them 'counter', 'milliseconds', 'seconds', 'minutes'
Always
-Add 20 to 'counter'
(Yes I know, it won't be synced to real time etc etc. But let's assume DudeHuge doesn't need/want real time and has his game on 50fps)
-Set 'milliseconds' to value("counter") mod 1000
-Set 'seconds' to (value("counter")/1000) mod 60
-Set 'minutes' to (value("counter")/60000)
Alternatively, you can replace -Add 20 to 'counter' with -Set 'counter' to timer
if you do want it to be synced with real time.

I've decided to use the widget it works brilliantly for what I want it for. Thanks for the enlightenment on all this stuff guys I appreciate it.

When people say miliseconds or seconds, at least to me, it's automatically assumed that they're talking about accurate time, not internal game time. I mean if you you're talking about 1 second internal to the game, 1 second is going to be twice as long at 30fps then it is at 60fps, which could be both undesirable to some people and highly desirable to others. Few people ever consider this, which is the entire reason why I was trying to put it out there.

i see but its also desirable to have things in the game run at the same speed regardless of framerate. time based movements. thats why in most games when the frame rate drops you still move just as fast, just in fewer frames updated at longer intervals. i see where that can cause problems in mmf. i dont think the built in movements are timer based are they? and most custom movements dont use a time delta for movement.
i may update my widget to flag whether or not to use internal time based on framerate, or accurate external time. thanks brandon.

Actually, they achieve that by skipping frames, not by using external loops. It's actually highly undesirable to use external loops for in-game actions, especially movement based. If your game suddenly dips in framerate, you'll start getting a lot of varied results. For example, if you have a player that falls 1 pixel every 0.1 seconds and your game suddenly hitches up for a few seconds, he's going to be short cut his jump and that's going to cause a lot of frustration for the player. It's best to use internal loops and just turn on machine independent speed. That way your game still relies on it's internal loops, but skips rendering frames so as to keep the game from being slowed down by it's ability to render.

what? external loops?
not when its based on difference in time. delta.
mmf loops 50 times a second. it it sudennly increases to 100 the total distance moved will be exactly the same. it will move according to the difference.
read this. im not sure im communicating what im actually thinking of well or you arent reading it well. this is what im talking about.
