Hi, I've been playing a game from a few years back (I really enjoyed it) and I found that it was open source on github. I would love to make my own version and see how it goes. I have experience with python as a hobby, and I've had a go at c++ - I made a few games with the sdl library. The github link - https://github.com/id-Software/RTCW-SP It will be great if I could at least render a level and a character. From what I see, the source has everything I need apart from the graphics. If someone can …

An example showing how to use the wx.media.MediaCtrl() widget to play MIDI, MP3, WAV, AU, AVI and MPG audio and video files. I have only tested it with Windows. If you are very ambitious, you could use a random graphics display with the sound, or tie the slider position to a slide presentation.

So given the following code (not my actual code since it would add unnecessary lines): typedef struct block{ int a; int table[64]; }block; typedef block* block_ptr; void getValues(block_ptr node){ int i, j; for(i=0; i<5; i++){ for(j=0; j < 15; j++){ node[i].table[j] = j; } } } int main(){ block node[10]; getValues(node); printf("%d\n", node[4].table[2]); return 0; } Why does it print out garbage values instead of, in this case, 2? And how can I fix this issue? Thank you for your time.

A palindrome is a phrase that reads the same forwards as it does backwards. For example, “a man, a plan, a canal, Panama,” is a palindrome. Write a program that uses a stack data structure to check for palindromes in each line of a text file. Test your program on the following example text file, A man, a plan, a canal, Panama. This line is not a palindrome Don't nod The next one might be my favorite Taco Cat! Another non-palindrome Rats live on no evil star. If your program finds this line, it's not working Neil, a trap!

Has anyone experienced the "Not Found" error usin the shiny package in R? I keep seeing 'Not Found' when trying to load my Shiny application, it seems to be that R cannot find the Shiny server, I have tried reinstalling all packages and still no luck. The strange thing is that it works the first time I open R Studio, then it doesn't hereafter.. I have attatched a working example and a screenshot for insight. --- title: "Benchmarking Algorithms for Credit Card Fraud Detection" output: flexdashboard::flex_dashboard: orientation: columns vertical_layout: fill social: ["menu"] runtime: shiny #options: (shiny.maxRequestSize = 1500*1024^2) --- ```{r …

Hey everybody, I was just wondering, how do you create Lens Distortion in OpenGL? As in, the rendered image looks bloated or sucked in when you implement it. I would typically want it in a simple format that works nicely and doesn't eat up too much CPU. As an extra, how about a spiral distortion? (I've seen it once when I was playing C&C Yuri's Revenge) Thanks in advance.

This short Python code gets the local time from the PC as a formatted string using time.strftime('%H:%M:%S'). The time string is displayed in a label using a larger font. A recursive function checks the time five times per second, and updates the time string, if it has changed. Five times per second may sound like overkill, but keeps the display from acting spasmodic.

Years ago I wrote a program in Fortran for a structural analysis class. At the time I had very little programming experience and mottled my way through the assignment. Fast forward to now and I'm attempting to teach myself Python 3. I figured I'd would try to convert the old program from Fortran to Python. I've made some good progress but I've hit a wall. I've got the program running to the point where all the element stiffness matrices are defined and combined into the structure stiffness matrix using the code number technique. The structure stiffness matrix is triangular. At …

Hi. I want to detect a face and draw line exactly around the face to crop it. I searched a lot and used the EmguCV face detector. but now my code just draw a "rectangle" around the face and if I crop it, I will have a rectangle with a face inside it and it's not useful for me. this is the core of my simple code: CascadeClassifier _cascadeClassifier = new CascadeClassifier(Application.StartupPath + "/haarcascade_frontalface_alt_tree.xml"); using (var firstImage = Image.FromStream(saveImageStream)) { var bgrImage = new Image(new Bitmap(firstImage)); Image grayFrame = bgrImage.Convert(); var faces = _cascadeClassifier.DetectMultiScale(grayFrame, 1.01, 1, Size.Empty); foreach (var face …

Hi everyone, I'd like to ask you all to help me with this two questions and I've been faced recently, 1.What would be the algorithm which takes the pointers of two Binary Search Trees roots, if equal returns true if not FALSE. (both BSTs are the same as well as the corresponding nodes.)? 2. how many times does " cout " execute? int m=0; for(int i=1; i<=n; i++) { m=m+i; for(int j=1; j<=m ; j++ ) cout << j; } thank you all for you helps and replies in advance.
