This lab is due by April 03, 2016 11:59pm. Concepts For this assignment, you have the opportunity to play with the power that SFML (a special framework called Simple and Fast Multimedia Library) offers. SFML SFML is a multimedia Application Programming Interface (API) written in C++ with bindings for various programming languages, including Java, Python, and Ruby. SFML provides an easy way to write code that requires graphics and/or sound effects. SFML is the chosen platform for many cool games, including the Atom Zombie Smasher. You can check out everything SFML has to offer by reading the SFML documentation. Before you Begin For this specific lab you should download this project template that has initial code and other resource files for you to get started. This file should work with Visual Studio 2015 (on campus or on your home computer). If you are not using Visual Studio (e.g. CodeBlocks, XCode, Eclipse, etc.), then it is your responsibility to install SFML for your chosen IDE. We will be grading these SFML assignments against Visual Studio so be sure your code works with the template provided on the lab computers. Start the extraction process now, and then read the rest of these instructions (as the extraction process might take some time). Say what? How do I "extract"? First, save the file linked above to your Z drive Note: we will always assume you are working on a Mines computer. It is your responsibility to modify these instructions if not. After you've downloaded the zip file, you need to extract the contents. (We always use Windows Explorer to move and extract contents of a zip file.) You can extract the contents of the zip file anywhere onto your Z drive, but it must be on your Z drive (might as well put it into your CSCI261 folder). Click on the Start button and select Computer in the middle of the right side of the menu. This opens Windows Explorer, not to be confused with Internet Explorer. Navigate to the zip file downloaded previously. Right-click on the zip file and choose Extract All... from the pop-up menu. The next step is the most important in the process ... please be careful! In the dialog that opens, delete what is there and type `Z:\` Again, you may specify any folder on your Z drive (other than the `adit` folder), but it must be on your Z drive. If you want to place in your CSCI261 folder, then type the following for the extraction folder: `Z:\CSCI261\` Click Extract. Depending on your system's configuration, you may be asked whether you want to copy the extraction process without encryption. If you are asked, mark the option ''Do this for all current items'' and click YES. See the example below. Then, using Windows Explorer, rename the project folder to Lab09. Open and Run the Project Launch Visual Studio, if you haven't already. When the IDE is loaded, pull down the `FILE` menu, expand the `Open` sub-menu, and select `Project/Solution...` Navigate to the Lab09 folder created previously. Select `sfml-template.sln` and click the `Open` button. Now, right click on Solution 'sfml-template' and rename the Solution to Lab09. Do the same thing for the Project. NOTE: As you likely know by now, another option is go into the Lab09 folder and double click on `sfml-template.sln` file. (If receive the error 'Security Warning for Empty Project', click OK.) Then do step 5 above. Instructions First, take a look at the `main.cpp` file provided in the SFML template. In class, we discussed each of the commands shown (e.g., creation of the window object and the polling for events); ask questions if there is any confusion. Second, we also saw the development of a smiley face in class today. The complete code is available here. A few key lines of code covered follow: // Draw a circle object called star and color it yellow CircleShape star; star.setPosition( 15, 15 ); star.setRadius( 300 ); star.setFillColor( Color::Yellow ); window.draw( star ); // Draw a rectangle object called rect and color it blue RectangleShape rect; rect.setSize( Vector2f( 45, 150 ) ); rect.setPosition( 200, 150 ); rect.setFillColor( Color(0, 0, 255) ); window.draw( rect ); // Draw a text object called label Font myFont; if( !myFont.loadFromFile( "data\\arial.ttf" ) ) return -1; Text label; label.setFont( myFont ); label.setString( "Hello World!" ); label.setPosition( 250, 520 ); label.setColor( Color::Black ); window.draw( label ); Your job is to draw something in SFML. What you draw can be anything you want EXCEPT a smiley face (e.g., a tree, a bike, a dog, a word using rectangles/circles, etc.). For full credit, you must draw at least five shapes. Be creative and have fun! Possible Extra Credit You can earn 2 points of extra credit if the item you draw actually moves (yes, is animated - awesome!). Animation in SFML is actually easier than you might think. As you know, you add all your draw commands in the window loop: while (window.isOpen()) { // ADD SEVERAL DRAW COMMANDS HERE // Apply all the draws to the screen window.display(); } To create an animation, you only need to change the draw commands a small amount that are executed on a given loop. Try it! Lab Submission You will submit your solution to this lab with the rest of Week09. Detailed instructions for doing this are posted in Assignment 09. Remember your smiley face solution for Assignment 01? You've sure come a long way since then! Do you recall how we had a prize for the best smiley face submitted in all sections (a Free HW)? That was cool. Let's do this again for Lab09. That is, we'll have a prize for the best Lab09 submitted in all sections. Good luck! This lab is due by April 03, 2016 11:59pm.
