Iggy the post that were auto formatted incorrectly by 420chan.
Just goto rhe w3schools link or study the screen shot I took for the working code.

BTW I did it the hard way.

Hope this is helps you in class my friend.

I prefer JS over Python for many reasons not only because it is the web standard because there are so many ways to do the same thing. Also I haven't coded much in Py.

My 3 fav right now have to be JS/PHP/C#, in that order. After that I would say VB because of the .NET framework like C# and C++ for .NET aka Managed C++ is not bad. Java because of its syntax is much like C# is good and It is good for Android projects.

Just pick a language that is widely used and master it. or else you will know alot of diff ones but master none. Go with C# for desktop/Mobile and JS for the Web and master those. I would say spend 2-3 years using just those languages. - BrU

hi 420chan. i want to be able to assign sound files (musical notes played on an instrument which i will have recorded) in whatever order i want and at assigned intervals. i want to "compile" and output to the speakers or to a larger sound file. the only experience coding I have is client side (web design) :/ javascript always seemed too hard. any tips where to start? C? could i even do it with javascript do you think? windows and linux both run programs written in C, right?

i just feel like i'll have the MOST authorship power (aka creative control) if I can make the program that orders the music at its most basic level, instead of relying on commercial software that I had no hand in creating and thus may never quite fully understand. call me enthusiastic possibly, but i don't want to spend time trying to understand the DAWs.

feel free to ignore this post if you think I should be searching the search engines and studying on the programming languages on my own to find my answer. honestly, this post is as much a reminder to myself to find the information myself as it is a cry for help.

Check out chuck
https://chuck.cs.princeton.edu/

It's suited for most "music and programming" tasks. You can open sound files no problem, there is pitch shift, time stretch and so on. Realtime & sound file output is available as well.
You can even use midi & osc in a pinch (midi kind of sucks cuz you have to use the raw data, but it's there)

If you want something more modern and don't want to learn a new language there is something that works in JS (haven't used it)

Hello, I made and actually did all this (including the 'grad level' research electives, except for the coding theory book)
https://functionalcs.github.io/curriculum/

It's easier than it looks, it took me 3 years to do that. I did it about 3-4 hrs a day at first but then everything kind of snowballed and I finished it with only 1hr a day after the first year. These days I'm finishing The Art of Computer Programming series, I'm done up to book 4A and doing 4B draft at the same time. I just do it 20-30mins a day.

I cannot shill TAOCP enough, it totally changed me from amateur to professional computer scientist by just doing hundreds and hundreds of exercises. 20mins a day, for one year, it's all you need for the first book. Anyway, pick and choose what you want from this list and enjoy

I make money from cloning shopify apps, and I work P/T on https://turtle.ai/ though much more infrequently these days. I started out shilling myself on elance (now "upwork") as a jr developer and literally taking jobs from 3rd world countries for less than I would spend on lunch. I also work 2 days a week at my local university doing "ML" (statistics) for a cancer research lab making peanuts but it's research, and fun to do, and I don't need the money. The book in that above link, "Parallel and Sequential Algorithms" was directly responsible for the lab hiring me. Anyway anons I'm here to tell you to try this have a good day.

I think because we need it as a base to build other skills on. You madman. I got another question regarding cs019, how do you know when to attempt the assignments? In the guide you go through 6 chapters and 2 lectures before attempting assignment 1. Docdiff, but how do you know exactly when to attempt each one, is it stated somehwere or prof K says directly when to do it or are you just backfilling and deciding when its best? ty man, you might birth a god as a result of this you know.

I think I might be too retarded to be a programmer. When I am given an assignment for my course work at community college I always have a hard time figuring out what needs to be done. I don't think I am that much of a failure at simple logic, but I'm not a genius so I can't figure out just what it is that I need to do. I am alright with structured programs and sometimes feel as if I excel at that but when it comes to making a bug move position in Java I am lost at the start. I cannot even form an algorithm to save my fucking life. Is there any hope that I would ever grasp everything in programming? I can't even figure out how passing methods/functions in any given language actually works. This is enough to make me contemplate suicide since this means it's one more thing that I would never excel at or one more thing that I would only excel at with the bare minimum. Who else feels this way?

I feel like I have high functioning enthusiasm or mild Asperger syndrome and when I was younger used to love to learn to script and program stuff now as I get older in my late 20s I feel a lack of sense and wonder and overloaded with so many choices.

I do gravitate towards easier programming languages like Python and C#.

I feel that drive died for me because everything has been done except I do have ideas to make video games but realize I suck at 3D Modeling. and 3D Level design. I know UNITY and C# is a perfect match however when it comes to coding something it's a pain in ass because I have to have my ideas written down and to apply them I need to figure out how to make my own graphics. I suck at graphics design so double whammy. let's assume I can create some 2d graphics and 3d graphics. Let's assume I can design a level. than I have to implement code and figure away to make proper AI.

Knowing myself and how garbage I am at advance mathematics because of my mild learning disabilities due to my ADHD and possible mild aspergers I feel like a complete retard.

>advanced math
Nah, it's not that advanced to apply the math just looks complicated on first view. Start with a 2D game for a mobile device, then as you gain interest back in writing games you move into 3D
For example this course: http://www.cs.cornell.edu/courses/cs3152/2020sp/lectures/index.php uses Java but I don't see why you couldn't substitute Kotlin for writing Android games or whatever the pref iOS language is, or whatever language you want to use they all have similar libraries or way to interface with the same library used in that course.

Note the lecture 'Graphics: Sprites' with a link to 'affine transformations', the link there is to a guy who watched Wildberger's Linear Algebra lectures and wrote a java program to move a fish around a screen https://code.tutsplus.com/tutorials/understanding-affine-transformations-with-matrix-mathematics--active-10884

We are doing the exact same lectures in the learnaifromscratch.github.io shitty workshop thing, you can skip everything there and just start with linear algebra, because the further the lectures go on Wildberger teaches polynomials, differential calculus (curves) etc. Cornell even has a few slides about projective geometry and perspectives, with additional articles that link to how to write perspectives in 2D to make your graphics look better... and this is also all in Wildberger's lectures too https://medium.com/retronator-magazine/game-developers-guide-to-graphical-projections-with-video-game-examples-part-1-introduction-aa3d051c137d

The Cornell player behavior slides show that it's just rule based AI, using a decision tree, they set this up with FSM diagrams which are similar to the DFA lecture in the AI workshop we did where no math is needed. When character comes across rule, follow this path. This explodes in complexity so they take the FSM diagram and model it as a decision tree using model-view-controller .. all explained in the software workshop in a single lecture. Libraries already exist for this with methods built-in, you aren't constructing them from scratch.

Finally in 15-462 CMU's 3D computer graphics course you'll see things like cubic B-Splines and linear transformations in animations such as this: https://www.youtube.com/watch?v=XVTw68iHef0 and note this is lecture 25 in Wildberger's linalg series, so you would start in the Wildberger world of simple complexity free algebraic math and then progress into the abstract world of kinetics in those graphics classes to write your own 3D characters but you will already know how it all works, so it's just a matter of figuring out the notation to use the existing libraries. Research and development in 3D optimization you may even be interested in, or more advanced character AI, to me this is how I build enthusiasm, understand it at the basic level, progress to find out there are hard unsolved specific problems in that space, wonder how I can solve the problem so then motivated to research this area instead of not having a direction and feeling overloaded with choices.

*java oops meant actionscript, which is extinct but the concepts are the same.

Another simple example, Brown's 'topics in 2D engines' course shows how to use JavaFX's affine to keep track of transforms for drawing as you move around screens, this is all covered in Wildberger lectures too and easy to do. http://cs.brown.edu/courses/csci1971/lectures.shtml and if you google around Cornell has an 'advanced game design' course which is entirely mobile games, like how to create yet another tree that handles all the events going on, the best places to put event handlers for touch and release player movement, how to avoid problems with the accelerator on most devices, even more affine geometry projections.

Script-Oriented Game Design Patterns?

I'm having trouble finding any good resources for how to design my game around scripts.

It's not hard to parse an XML file and get data from it. It's even easier to use Java's ScriptEngine on a JavaScript String... Heck, you can even use Java as it's own scripting language with runtime compilation/reflections.
Actually creating script files / reading the data isn't the problem I face.

Thanks to Unity's massive popularity: when I try to look up design conventions for using scripts (in games), all I get is Unity tutorials.
I'm sure there's an obscure video with 2 views on it which answer's my question, I'm skeptical YouTube's algorithm will ever deem me worthy of seeing it, however.

My question is how should I use scripts properly? How do I design my code around scripts?

My goal is to write as much of my game as possible with Scripts instead of code. I intend the actual executable to be more of an engine/interface as a go-between between my scripts and Java / the various frameworks I'm using. I am aware of the extra processing overhead scripts add, but I'll just deal with that in loading screens. Being able to add new scripts at runtime is cool but not mission-critical.

Right now it feels like I could do ANYTHING I want with scripts, and I mean... functionally speaking, yes. But that's exactly the problem. It's exactly how I felt when I first discovered a Singleton. Needless to say, if someone feels like they can do "literally anything" they want, it's a sure sign they're about to do something stupid.

Is there a set of conventions / best practices/design patterns specifically concerning an application that revolves around scripts? I have no idea where to begin.

Any reading/resources concerning Script-Oriented software design would be greatly appreciated, thanks!

what you're doing in java is configuration which is a component of making a scriptable engine. Java is actually an amazing language for configuration files, but that's only half of what you need for a scripting engine and java kind of sucks at the other half.

c/c++/c# tend to have very well supported set ups for being wrapped by scripting languages in such a way where the scripting language can sort of wrap the code sort of becoming the executor within its interpreter; while java has that too with jni, it's kind of ass in comparison.

Based on what?

I work on embedded a lot. I like it. Back when I did .Net and VBA I had the strong feeling that I was working on top of a leaning tower of bullshit (the C# compiler is crap, VS2018 or whatever is slow and awkward) . Now, everything that's between me and my problem is a decent editor (I like vim), a decent compiler (Clang or GCC), and you can build the project by typing make on the command line, like God intended.
