Hi everybody,

Yesterday I looked for this example in the doc :

http://www.appgamekit.com/documentation/examples/timers/1_timer_movement.htm

I wonder, this is not the same thing that use the GetFrameTime() command ?

See here : http://www.appgamekit.com/documentation/Reference/Core/GetFrameTime.htm

It seems that GetFrameTime() command return the same things that the difference# variable on the sample, doesn't it ?

I try to play with timer based movement, but I have the impression it's more easy to use GetFrameTime() instead of a lot of calcul in the loop.

I don't know that's why I ask the question, may be it's not the same thing ?

In add, it seems that when we use a timer based movement we have to choose a great number to make sprite move quickly (like 100 or 200 per frame).

Thank you for help

Waow Nobody knows ?

What about the vsync ?

Thank's

What about the vsync ?

V sync have well bin removed to get it to work better on more devices?

Thats why some people gets some screen tearing on there apps.

I have bin thinking exactly the same as you about the GetFrameTime()

I simply use the version from the sample of timed movement that comes with the agk

I just bumped this as your right
i replaced my code with only 2 lines!

global GFT#

do
GFT# = GetFrameTime()

move sprite bob,200.0*GFT#
sync()
loop

No nead for calculations or any functions as its built in to tier 1

Thank's

For vsync, without it, the apps are not smooth. And on Windows / mac we have screen tearing.

We need this command to have something that is correct imo. After, people are free to use it or not (depends of the device).

In add, may be it's possible to activate it on tier 2 ?

Give the tgc it as an request about the v sync ?

i dont have any screen tearing yet in my app, so i dont nead it right now

It depends of a lot of things. Screen tearing appears if you monitor sync is not the same of the game sync.

Wait for the sync is better to make the game be able to be smooth on different PC's.

With the base timer movement, that's permit to make the apps smooth whatever the PC.

But I wonder if we can setup the vsync on tier 2, may be with some c++ commands ?

in Tier 2 use

agk::SetSyncRate(60,0);

we have in tier 1 setsyncrate too.

But it's not the same thing. With this command you limit the fps to 60 but do not activate the vsync that permit to synchronise the screen refresh time with the game.

If you make a request in the issues board, we can look at it down the line: http://code.google.com/p/agk/issues/list

Lee its always good to have the option to use it or not

Love the agk by the way

But please get on with the bugg that crashes apps with an bytecode around 900 kb-1 mb
