SFML? What do you get when you divide screen width or height by sprite width or height?

I am new to game programming and I am constantly seeing people divide the screens width or height by an in game objects width or height. My question is what does the number that they receive stand for. What exactly do you get when you divide the screens
dimensions by a in game objects dimensions?

You can calculate how small your object have to be drawn from the original , if you zoom your camera (screen) out and vice versa in 2D. In 3D you will require to use matrix transformation instead.
See this example:
1) Your original designed dimensions
Screen_width_old , Screen Height_old , Sprite_width_old , Sprite_height_old
2) After window resizing:
Screen_width_new , Screen_height_new (new values)
Then, Sprite_height_new=Sprite_height_old * (Screen_height_new / Screen_height_old) ;
also
Then, Sprite_width_new=Sprite_width_old * (Screen_width_new / Screen_width_old) ;

What release level of code do you get when you download a disk image (ISO/IMG) of a click-to-run Office 2013 product?

I’ve asked a similar question to this on an Office Community Forum but nobody knows the answer. So
I was hoping that an IT professional responsible for installing and deploying Office 2013 might know.
If you download an installation disk image (ISO/IMG) of a click-to-run Office 2013 product from office.microsoft.com/myaccount (Account Options:
Install from a disc > I want to burn a disc), what release level of code do you get?
Now that Service Pack 1 is available, do you get a disk image with Service Pack 1 incorporated?
Or do you still get the RTM (Release to Manufacturing) level of code?

Diane, thank you for the reply.
I was hoping that someone who has downloaded a disk image since SP1 became available would be able to confirm that for a fact.
I have just found a good description of Click-to-Run on Technet that I didn't know existed. The link is: http://technet.microsoft.com/en-us/library/jj219427(v=office.15)
The article states:
"Click-to-Run products that you download and install from Microsoft are up-to-date from the start. You won’t have to download and apply any updates or service packs immediately after you install the Office product."
This statement is probably true if you click the Install button on office.microsoft.com/myaccount and install "in real-time" over the Internet. However, I know for a fact that it is not true if you order a backup disk (Account
Options: Install from a disc > I want to purchase a disc). All you get is RTM level code (15.0.4420.1017).
So I still feel uneasy about what release level you get if you download a disk image. I don't want to download what might be the better part of 1GB of code over the Internet only to discover it is back level.
Addendum (6 April 2014): I decided to perform an experiment. I looked at the size of the data on my backup disk which contains RTM level code. It is 2.04GB. I then went to office.microsoft.com/myaccount and clicked to download a disk
image of my Office 2013 product. The pop-up window that asks me whether I want to Run or Save the file informed me that the size of the file is 2.04GB!!! I cancelled the download. I strongly suspect that, if I had continued with the
download, I would have received the same RTM level code I already have dating back to October 2012. I think this is awful customer service. To some extent, I can understand the logistical problems of replacing backup disks lying in warehouses
waiting to be shipped. But I cannot understand why disk images on download servers cannot be refreshed quickly.

HT1688 It would be nice to see iMessage on/off on the quick access screen you get when you swipe up in iOS7.

Trying to quickly send a text message to an email is something I would like to do easily, but with iMessage turned on you can not do that. The ability to turn iMessage on/off should be on the quick access menu you get with iOS7 when you swipe up. Agreed?

You can provide feedback to Apple here:

Personally I've never had the need to turn iMessage off.

What do you get when you add two Mac Pros together??

Hi, has anyone "linked" together two 8-core Mac Pros to make the system work as one 16-core processor? Is this even possible?
Thanks in advance.

There have been some problems accessing pages on the Apple web site. If the hyperlink gives you a "We're sorry" message, try again.

Are there any additional templates for pages other than those you get when you install the program? If so, where do you find them?

I am looking for additional templates for iWork, specifically for pages. Does Apple or anyone else have them?

Yes there are plenty of third-party templates available for iWork applications. Try doing a search on Google or software download pages such as MacUpdate or VersionTracker.
A few links to get you started:

I am not seeing the URL preview you get when you hover over a link. Why?

Until today, when I hovered my cursor over a link, a preview of the link's URL would appear on the lower left of my screen, above the Start button (I use Windows Vista). Currently when I hover over a link, no preview appears, so I don't know the web address of where I'm going when I click on the link. I thought that maybe this was due to updating to Firefox 19.0, but my friends who have also updated say that they can still see the URL preview. Did I somehow turn off the URL preview by accident? If so, how can I turn it back on? If not, why is it gone?

Do you see toolbars like the Add-ons bar (Ctrl+/) or the Find bar (Ctrl+F)?
Start Firefox in <u>[[Safe Mode|Safe Mode]]</u> to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
*Do NOT click the Reset button on the Safe mode start window or otherwise make changes.

Hi, Im having trouble with my Iphones sounds, it wont let me listen to music, watch videos, notify me if i get a text, basically everything that makes a sound is no longer working. The volume level you get when you play music isnt there, HELP?!

Hi, basically i have no sound at all on my Iphone, it doent notify me when i get a text, when someone rings, when i play music or watch videos, the volume slider that is usually present while watching videos or listening to music is no longer there at all, ive turned my phone on and off a couple of times now ive put headphones in and out to see if i had a sticky jack but still no luck Someone help??

And to clarify, these are all iTunes movie and music downloads, so there should not be a compatability issue. And no, the iPod did not come damaged from Apple, it was a hand-me-down from a friend who busted the internal speaker. But it's never done anything like this before. It just had crappy sound. And yes, the timing of the movies and music having issues is the same as the speaker dying. And no, this has NOTHING To do with music videos. I don't have any on any of our devices.

Turning Off that Stupid Beep You Get When You Open Your Laptop

Any Ideas? I have a Lenovo X200, and I already tried setting my sound settings to "no sounds." I'm running Windows 7 without any Lenovo drivers (except for the trackpoint)--and if at all possible, i'd like to avoid the drivers.

you can do that through the BIOS menu.

What does it mean when you get a "The iTunes library file cannot be saved. There is not enought memory available." ? And what can I do to correct it?

Well, I installed the latest iTunes this AM, works perfectly. Although for some reason it did lock up after playing a song today.
Horror stories? That's a bit overly dramatic.
No, it isn't.
The issue you are experiencing is one that has occurred in multiple versions of iTunes, a simple search would have revealed this.
A simple search was conducted, no one seemed to have an answer. Do you always adopt such a haughty attitude? Or was I just lucky.

HT201299 what does it mean when you get this message on the Iphone? "online maps consume data traffic"

That means that if you use online maps, it will consume data. If you're on WiFi, no worries. If you are on cellular data, then it will eat into your cellular data plan.

What do you do when you get a 'connection to mail server failed' message?

What do you do when you get a "connection to mail server failed" message?

if it used to work and you did not change anything then it's most likely the internet connection or the mail provider server which are having the problem in which case you wait
if not then they changed their settings and you needs to adjust to their new settings
or your carrier changed their settings so they block the required ports
