海外TECH	DEV Community	JS1024: A post-mortem for Space Hopper	https://dev.to/michaelprimo/js1024-a-post-mortem-for-space-hopper-52cl	JS A post mortem for Space HopperJS is one of that rare competitions where you need something really special even to start partecipating The premise is this Create a javascript shader program that has bytes or less and make it do something great Is this possible to do one useful script in under bytes I only made with minimal compression a framework in less than k Crono js a framework which helps people who make animations and games managing inputs and loops delays so since I had minimal knowledge of Canvas I thought it was a good idea to start learning by doing this So Let s talk about Code Golfing No you don t play golf and code the same time In golf you need to throw the little ball on the hole of the camp Less throws you do the better Same with programming when you do a software in less bytes as possible for a task you do better than one who done the same thing but with more bytes for giving the software more readability You need to throw away all the best practice of program and optimization for both humans and machines and that s what I did for Space Hopper a game in bytes of Javascript Yes this boy here How JS work There are four categories HTML Project submit something in bytes HTML included Canvas Project Shader and P js project Except for the HTML project category you need to download a shim file html preconfigured and not editable and then add your script inside When it will be the time on July submit from one to twenty project for partecipating Since I wanted to learn making games in Canvas after done DOM games before I decided that category and starting this journey to scratch Pacman a good example of what a game is What is Canvas and why using it Canvas is a HTML element that makes possible visualizing interactive or not animations on browser games too You are free to the structure of a website and making grid based games or anyway slow ones and thinking about every button broke because someone use a different browser you can use a responsive element and make a good what you want cross platform game Deal Deal accepted The Making of Space HopperI started from a blank canvas with two moving circles and then I passed to use Unicode emoji you can have characters with bytes Another deal again But we will talk later about this on a black purple screen then I added stars in an array and update movement every frame Without knowing I invented spawns and knew this when I made the frogs in Wonder Wanderer but that is an another story This project is created with this on mind I had to learn Canvas well for that I ditched p js for self learning Since it s part of my job it must be a game It must be good as a game I normally do without limitations so I have to put quality on this It must have sound effects if possible music but I asked too much also I tried putting something but it sounded terrible so I left only SFXs It must be responsive and playable on both tablets desktops and even mobile The background must be animated and dynamic for example the increasing speed of the stars is one of that features The game must be a challenge to code golfing about so no clean code in bytes and forget the rest I should add visual effects while hopping and crashing and while having extra lives Since I want to make web and mobile games on my website here michaelprimo it that was my thing to do After the background setting I needed to play with x and y of both the sprites player and enemy and make them collide The collision is one of the weirdest thing of the game since I made something like if the enemy is on the same line as the player and in a certain range then you lose a life without being accurate But the game was done The first version of the game Sure Just put some wrapping stars in an array randomic position of the enemy asteroid click for avoiding it and you are done right But I wasn t right There was room for improvement I discovered RegPack and found I had still bytes more to use so I added more depth to the stars sound effects and powerups to make the creature more likable and giving more variety to the game And then I made the game I see there is again room of improvement for it Next year we ll see if I ll make a Space Hopper for celebrating this creature born on this contest and see how I am improved on time Results and future projects for Space Hopper The results for Space Hopper were th so pretty low For Space Hopper I think to improve code golfing skills and make more stuff as possible inside the game also make powerups more clear and changing a bit the game making it more fun and try to make something different also since Safari doesn t visualize well some Unicode characters I ll have to draw something using Canvas JS was a good contest a good try to continue what JSk made before and I hope to see contests like this again	2021-08-01 10:16:51
海外TECH	DEV Community	C++ Cheat Sheet for Beginners 🔥	https://dev.to/unitybuddy/c-cheat-sheet-for-beginners-33h1	C Cheat Sheet for Beginners Hello buddies I recently discovered the power of cheat sheets and thought of making a cheat sheet for C which has a myth as too hard Any language even Python can be hard of you didn t try C an extension of Cーwhich we said was an easy language to learn ーis a general purpose programming language Google Chromium browser several Microsoft applications and even financial modeling at Morgan Stanley are said to be done with C If you say it is hard it is only for reasons It has complex syntax to support versatilityIt is a permissive languageーyou can do everything that s technically possible even if not logically rightIt is best learned by someone who already has a foundation with C programmingOkay these are just to note for a while Now forget all about the things take a deep breathe and start This won t be boring I will share games with you so you can relax Introduction What is C C is a general purpose programming language that was developed as an enhancement of the C language to include object oriented paradigm It is an imperative and a compiled language C is a middle level language rendering it the advantage of programming low level drivers kernels and even higher level applications games GUI desktop apps etc The basic syntax and code structure of both C and C are the same How C is Used C is used for all kinds of applications from computer games to OS and compilers This programming language adds onto C Programming language and includes modern programmingC is so compatible with C that it can compile more than of the C programs without changing even a single source codeAnything that computers can physically perform from manipulating numbers to text can be programmed using C include lt iostream gt using namespace std int main cout lt lt Hello World return Let s break up the code to understand it better Line include lt iostream gt is is a header file library that lets us work with input and output objects such as cout used in line Header files add functionality to C programs Line using namespace std means that we can use names for objects and variables from the standard library Don t worry about these Just think of it as something that almost always appears in your program Line Blank line C don t care about spaces Line Another thing that always appear in a C program is int main This is called a function Any code inside its curly brackets will be executed Line cout Pronunciation see out is an object used together with the insertion operator lt lt to output print text In our example it will output Hello World It s easy to remember this from pronunciation see out Line return ends the main function ️Things to note Every line in C is ending with semicolon Do not forget to add the closing curly bracket to actually end the main function Comments in C can be single or multi line and start with and close with Comments can also start with extending to the lines end Let s learn more about Data types in Future Variables are containers for storing data values In C there are different types of variables defined with different keywords for example int stores integers whole numbers without decimals such as or double stores floating point numbers with decimals such as or char stores single characters such as a or B Char values are surrounded by single quotesstring stores text such as Hello World String values are surrounded by double quotesfloat stores Boolean values with two states true or falseA variable in C must be a specified data typeint myNum Integer whole number without decimals string name Unity Buddy String text char myLetter U characterfloat myFloatNum Floating point number with decimals We have already learnt about cout which is used for Show Output So for take user input we use opposite side cin it means See In See out and See In It s easy Let s take an example int x making a variable called x cout lt lt Type a number Type a number and press entercin gt gt x Get user input from the keyboardcout lt lt Your number is lt lt x Display the input value️Remember cout is used to show Output and uses the insertion operator lt lt cin is used to get User Input and uses the extraction operator gt gt A string variable contains a collection of characters surrounded by double quotes string myName Mr Unity Buddy To use strings you must import lt string gt library include lt string gt String ConcatenationTo combine two strings we use sign string name Unity Buddy string age years old cout lt lt name age String LengthTo find the length of the string we can use length function size function is also used for the same thing string name Unity Buddy cout lt lt The length of your name is lt lt name length C supports the usual logical conditions from mathematics Less than a lt bLess than or equal to a lt bGreater than a gt bGreater than or equal to a gt bEqual to a bNot Equal to a b IfIn C we use the if statement to specify a block of C code to be executed if a condition is true if gt cout lt lt is greater than ElseThe else statement is to specify a block of code to be executed if the condition is false int time if time lt cout lt lt Good day else cout lt lt Good evening Outputs Good evening Else ifUse the else if statement to specify a new condition if the first condition is false if condition block of code to be executed if condition is true else if condition block of code to be executed if the condition is false and condition is true else block of code to be executed if the condition is false and condition is false Loops can execute a block of code as long as a specified condition is reached Loops are handy because they save time reduce errors and they make code more readable While LoopThe while loop loops through a block of code as long as a specified condition is true int main int i while i lt cout lt lt i lt lt n make new lines for each i Add return output The Do While LoopThe do while loop is a variant of the while loop This loop will execute the code block once before checking if the condition is true then it will repeat the loop as long as the condition is true int i do cout lt lt i lt lt n i while i lt It means While you re reading this your knowledge improves Hope you got it For LoopWhen you know exactly how many times you want to loop through a block of code use the for loop instead of a while loop Think you get for hour if you work till pm and you always working till pm You are sure about it So you have to use a for loop to estimate your payment for bool works true works true pay pay cout lt lt pay lt lt n this is not the best way to do it Just to understandIf you re not sure you work till pm you have to use a while loop while bool works true cout lt lt pay lt lt n pay pay Break and ContinueThe break statement can also be used to jump out of a loop for int i i lt i if i break cout lt lt i lt lt n And the continue statement breaks one iteration in the loop if a specified condition occurs and continues with the next iteration in the loop This example skips the value of for int i i lt i if i continue cout lt lt i lt lt n That s about loops Arrays are used to store multiple values in a single variable instead of declaring separate variables for each value To declare an array define the variable type specify the name of the array followed by square brackets and specify the number of elements it should store string games We have now declared a variable that holds an array of four strings To insert values to it we can use an array literal place the values in a comma separated list inside curly braces string games COD Cyberpunk Among Us Warplanes Access the Elements of an ArrayYou access an array element by referring to the index number Note Array indexes start with is the first element is the second element etc string games COD Cyberpunk Among Us Warplanes cout lt lt games Outputs CODTo change an element in an array string games COD Cyberpunk Among Us Warplanes games Overwatch cout lt lt games Outputs OverwatchLast Part You re a awesome learner C provides some pre defined functions such as main which is used to execute code But you can also create your own functions to perform certain actions To create often referred to as declare a function specify the name of the function followed by parentheses void buddyFunction code to be executed Call a FunctionDeclared functions are not executed immediately They are saved for later use and will be executed later when they are called To call a function write the function s name followed by two parentheses and a semicolon In the following example buddyFunction is used to print a text the action when it is called void buddyFunction cout lt lt I am happy now int main myFunction call the function return Outputs I am happy now So buddies this is the end and hope you learnt something Did I miss something that must be included Please let me know in comments And Thanks for reading this long cheat sheet and Happy Coding Originally published on Hashnode	2021-08-01 10:11:19
