sync and cls used like that kills your framerate.

making a 3d panel and fading the panel with fade object etc would be a lot more proficient in 3d or 2d.

should be



with



right before



Indi was not right actually about the sync and cls(sorry mate but its true)

A^2+b^2=c^2, but D^2-A^2/g^2*t-r-o-u-b-l-e = w+i+t+h / a*(c*a/p^i+t+o+l)/T+rhyming+with/P+f/o*r^(p-o-o/l)

That equation has a quote from a movie in it. Find it for a cookie

Yep, has no effect on FPS.

Here's my version. The RGB command slows the program down if you use it loads like that, so I substituted it for the multiplication factor of red.

a cls is a sync - a sync is a sync
when your program grows it will give you grief.
good luck to you if you think it doesnt, been down that road many times.

no its not, cls clears the screen. What he is doing if anything will increase the fps because the computer doesn't draw anything to the screen untill the end of the loop so it is just figuring out what the screen should look like and not having to draw it constantly.

Sorry indi didn't think that's what you meant.
I thought you were commenting on the way he had SYNC and then CLS afterwards.

Tested it out and you're right! CLS does do a sync??? that's stupid
They don't say that in the tutorials, unless I missed it.

I guess you would get rid of the SYNC
so why do tutorials always have CLS at the top?

Under what circumstances? If one uses SYNC ON at the beginning of the program, the CLS doesn't behave the same as a sync.

Here's a couple examples. The last one is so slow, that the mouse pointer doesn't even move. The refresh takes several seconds.









Enjoy your day.

SYNC and CLS are not interchangeable

using a backdrop on without cls i get 457 fps.




using a cls i lose about 30 fps.



naturally for the classic users change fastsync to sync.
As you clearly see it draws fps.
A sync is really a clear screen then repaint screen.


If you wanted to know as well for yourself instead of stabbing in the proverbial dark you would have found out in minutes writing your own examples.

If you want less fps in your programs be my guest pfft lmao.

It's just the statement:

Quote: "a cls is a sync - a sync is a sync"


Is not entirely accurate and may lead some astray to thinking that one command can be used for the other. A CLS will not adjust the screen refresh timing according to a set SYNC RATE. A SYNC wil not clear the screen in all cases. It may in a 3d situation, but it will not clear a 2d screen.









A CLS without a SYNC when SYNC ON has been set will slow to a crawl as the system waits for the refresh from SYNC.

You are correct in saying that using both at the same time will slow fps, but so will using any drawing commands. I just want to avoid confusion that CLS cannot be used in place of SYNC and SYNC cannot be used in place of CLS.

But thank you for the tip in speeding up code execution.

Enjoy your day.

As Indi's example is a DBPro example, I guess there's also the possibility that DBPro behaves differently to DBC in this respect. It does for many others.

Sorry hpfan, the answer is NO it didn't work
You can't assign a variable in the middle of a function call like that
Quote: "rgb(color=color+15,0,0),1"

Although it did actually compile????
Didn't work though

Apart from that it works, but here is an edited version


there was no need for the "if up=whatever then blah-de-blah" verses, they both did exactly the same thing accept for the change to the color variable. So what do we need to do? Change what is added to the variable! And since we already have the whole "UP" thing I just substituted its value for +15 or -15 and used it to alter the color variable. Easy peasy
Sorry if I was at all annoying in this post, it is late here
If you have any questions then post them and some other person will reply because I'm going to bed
