Lab #2

Keyboard input, flow control and sfml

 

The goal of this lab is to get experience with flow control, specifically if statements and for loops, and to gain familiarity with sfml features, like handling keyboard input.

 

• [20 pts] Project setup. Add the Lab 2 project to your CGT 215 solution

  • Retarget the project if needed (right click in solution explorer, select Retarget). There are different releases of Visual Studio 2017, and if this project was created in a different release then retargeting will be

  • Set Lab 2 as the startup project (right click project in Solution Explorer, select set as startup project). This will set Lab2 as the project that gets built and

  • Set titlebar text to “Lab 2” followed by your first and last

  • Demonstrate to the lab TA that your project has been correctly added to your solution in lab to receive full credit for this

 

• Multiple scenes. Your program should be able to switch between four different scenes. Keep track of the current scene using an int variable. Change the value of this variable in response to key presses. Specifically, when 1 gets pressed set the current scene to 1, and likewise for the 2, 3 and 4

 

See    the    Lab2.cpp    template    file    and    https://www.sfml-dev.org/tutorials/2.5/window- inputs.php for more details about handling keyboard input.

 

 

• [20 pts] Scene 1: A row of circles. Use a for loop to draw a row of 5 circles. The radius should increase from left to right. Each circle should have a different

 

• [20 pts] Scene 2: A grid of circles. Use a pair of nested for loops to draw a 5x5 grid (5 rows and 5 columns) of circles. The radius should change from top to

 

• [20 pts] Scene 3: Time based animation. Draw a grid of circles and make the radius vary with time. A variable named time is already created for you. Include the cmath header file and use the sin() function to compute a radius that changes with

 

• [20 pts] Scene 4: Your own creation. Create your own scene. Use at least 5 different shapes, 2 different colors and some feature not used in the previous scenes (such as a different shape, or outline color or rotation). See https://www.sfml-org/tutorials/2.5/graphics-shape.php for some ideas.

 

• Submit the lab by zipping up the project folder (the folder containing the vcxproj file for this lab) and submitting it to Blackboard by the end of this lab

 

Automatic point deductions:

• 10 pts: Problems with zip file, or submitted code does not compile. If the grader must make any modification to your code or project/solution file to compile it, there will be a deduction. If the code cannot be compiled you can resubmit, subject to late

 

• 10 pts: Code crashes. Even if your program temporarily gives correct output, if it crashes or exits unexpectedly there will be a

 

 

• See the syllabus for the late submission
