Normally you only have one Sync in your program - at the end of your main program loop. However, it's not uncommon to have more than one loop - like Main Menu screens - and they often need them too.

But, the point is that the Sync command tells DB to refresh the screen with all the changes your program has made so to keep your program running smoothly you should do it at the end of each loop cycle... and use it only when necessary.

Also, if you are putting sync at the end of your main loop, make sure you put

SYNC ON

at the top of your program. Otherwise DBPro is syncing in it's own time, and then you are forcing another one.

Try establishing a sync rate for the program to maintain at, like this:

SYNC ON : SYNC RATE 60

SYNC ON in and of itself will not make your sprites disappear. It simply is a way to make your program run more smoothly, by updating the screen only when it needs to. If you have indeed placed SYNC at the end of your game loop, I would need to see some code in order to help you further.

If I recall, sprites don't stay between syncs. So if you aren't positioning them every loop, then yes, they will disappear.

Soo, i dont see whats wrong with my syncs, idk maybe u guys know, the only sprite that appears is the 19, all the others dont.
But without the sync on command they all appear normaly, though i would like it to run more smoothly, so... what should i do?

How can you decipher how your code even runs? Not to be harsh, but this is a prime example of why GOTO should not be used. The first thing I would do is get rid of all of them, re-write the majority of code if you have to, but get rid of them all. You need structure to your code. For example, you need one main Do - Loop (or repeat - until loop). From this, you can call the subroutines / functions needed. Normally, you will get user input, move the user, move enemies, move shots, move the background, do collision, etc. and then place a sync just before the end of the loop. I would try to give you some example code using your code, but I honestly can't figure out what you want to do if you say, push the left arrow button, for example.

I would remove the function call to lol() and put a main loop in it's place.

LBFN is correct. There's a right and a wrong way to write computer programs - if that is you want to make life easier for yourself.

Unfortunately, your code is a fine example of how to do it the wrong way.

But, if you are new to programming, then you won't know about the right way. With that in mind, check out tutorial 2 here:

http://forum.thegamecreators.com/?m=forum_view&b=10&t=99497&p=0

There may be lots of other info you might find useful in that thread - particularly Tutorials For Beginners Parts 1 to 4.

It might seem a lot of bother for nothing, but believe me, ignore the advice and you'll soon be wishing you hadn't!

I've had a bit of trouble with sprite - I think we all have

- but something that has always helped when I am using sprites up the ying-yang is

sync on : sync rate ...

do
sync
all your code
sync
loop

the reason for the double sync is simple, check going in, check going out. You will find that there will be times when more than one sync is needed.

Jack and Jill went up a hill to fetch a pale of water... but Jill got tired of his s#%& so she shot him.

Daryn, that looks a bit wierd, I mean, as the code loops through, you do the following activities in your code:

sync
code
sync
sync
code
sync
sync
... etc etc etc

since there is no updating of any variable states, objetcs, or anything, you are sync'ing twice in a row, taking the performance hit of a double sync

I may well be wrong, but thats how I see it

This is not the Sig you are looking for....

I always put one sync at the end of my main loop. I have never seen a need for a second sync at the start of the main loop in order to display sprites. Sync tells the computer to draw everything to the screen. There is no reason that I know of to do that twice. I agree with Dia, you simply will take a performance hit by doing that.

Yitzu,

I believe that your code has been laid out in such a way that the sync is not being executed in a timely fashion. Whether you are using 2D or 3D graphics makes no difference. By using the sync command, you are telling the computer to redraw all of the graphics.

I have taken your code and edited it into a revised version that you can plug in what you want it to do. I hope you can see the benefits of writing a program in a more structured way. You obviously can use subroutines instead of functions if you want.
