      Guidelines and Netiquette   03/28/2017

      Posting Problems:   Having problems posting your topic? Read through this: To join, you agree to our terms and conditions and fill out and submit a registration form. An activation email will be sent to your email adress, so you'll need to verify your account. After that the account has to be validated by one of the moderators. This will mean that it can take up to a day to be activated. A couple of things to remember to ensure approval: Don't use an email address in one of those $2 four character .com domains eg. xyds.com. These will be deleted and the domain added to the banned list. Don't use an email address that is within a domain with a bad reputation for spam. A Google search is run on every email address and email domain. Don't sign up with an email address that doesn't exist, doesn't work or requires the sender to answer a quiz before their email can get to you. Put your country and or state and city in the signup form. Blank forms will go to the botton of the "to do" list. And make sure that your email address and your country match, saying you're from Alabama and using a .ru email address is not going to get you activated. After a membership is activated the first few posts will be monitored. Posting spam or unapproved topics described in the agreement results in an immediate ban. The email provider and the IP addresses associated with the account will be banned and all posts will be deleted. These strict measures have been deemed necessary to hinder spam. Sorry for any inconvenience this causes, but it's not liable to change. If, after reading this, you still can't post and don't understand why, contact one of the Moderators listed here.   Topic Guidelines   Including the following information can expedite an accurate response from board members: Must be a Specific Problem or Question related to web design and development Include Code in Question (wrap with   for small blocks of code and for longer blocks   ) Include Code Author Include Extra Notes/Modifications/Attempts Include web link to page/file when possible Content Guidelines   You may not post, upload, link to, or email any Content that contains, promotes, gives instruction about, or provides prohibited Content. Prohibited Content includes any Content that breaks any local, state, county, national or international law. Prohibited Content also includes: No direct or indirect advertising or websites, forums, products, services No hijacking of posts (do not post your question in someone elses) Content that infringes upon any rights [ex.

To get the full list, click "BB Code Help" underneath the clickable smilie face menu. Use   for small snippets of code Use   for lengthy snippets of code Use   if your snippet is HTML (optional) Use   if your snippet is SQL (optional) Rules of Conduct   Be nice. There's no need for calling someone stupid if they ask an 'easy' question. Keep your avatars and signatures absolutely child friendly. We have a younger audience on this forum. Keep your language appropriate for the same reason above. Do not PM moderators for help on the forum. Post on the topic, or create a new one.   Spam:   Recently, as you have all without doubt noticed, we have had lots of spam and advertisement on the forum. Therefore, we'd like to alert you as to what to do when you have found any of the aforementioned annoying messages: it. Immediately. Give a clear reason, please, if the advertising is not evident. DO NOT POST! Report, let the post stay as is, and we will get to it, meanwhile if you continue to post as normal in the other threads, it won't be on the top so long. Refrain from PMing the member. This won't help at all, as they are most likely spambots anyway. Thank you.       Images in signatures:   After thinking of users on dial-up, we have decided to enforce the following rules regarding signatures. Please pay heed to them. Respecting these rules is respecting the members on this forum with dial-up. Signature rules: No animated images AT ALL. No matter the amount of animation. Maximum image widthxheight: 300x150 Maximum image (file) size: 15kb Use calm colors. Do not use highly contrasting images in your signature, as this can get really annoying when seeing several posts from one member in the same thread. The same prohibited content goes for images as for posts. Lastly, use common sense. No lengthy signatures please. Save us some scrolling. Thank you.       Links in signatures:   Please understand that w3schools.com only exists because of voluntary work and is barely supported by the advertising littered throughout the tutorials and the forum. So, please, stop advertising other sites. DO not post links that drive traffic away from the w3schools domain - especially to a site that offers similar if not identical information. Please help support the site by keeping individuals on it. Thank you. Here are some guidelines as to what you can put in your signature: w3schools links --> allowed w3.org links --> allowed browser links --> allowed html editor links --> allowed personal sites --> allowed tutorial sites competing with w3schools --> NOT allowed sites completely irrelevant to webprogramming and this forum --> NOT allowed   Thanks for understanding, and for taking the time to read this. ~W3Schools Modstaff~

I was guided toward svg when I found out about vector resizable feature... now that I went through the svg guide on w3school(which was just a guise of it). I come to wonder if I can use that over canvas api?What do you guys think?Gaming propose, which one would be efficient in formatting games?

Normally games don't use vectors, so canvas is preferrable for games. Game programming is highly complicated.

 

SVG and canvas are two separate, independent technologies. If you want them to work together you're going to have to build your own program that does it. The only way to do that is if you fully understand how to interact with both canvas and SVG using Javascript.

I'm speaking on using only the svg instead of the canvas. Replacing canvas with svg canvas(the svg tag/element/node) as a surface view point for the game interacting and graphic. Edited by L8V2L

I was so gay(could have use happy, but I feel this word best fit the description) when I saw p.js, but as I study on the side more and more of svg, I'm sway by it's beauty. svg being a distance relative to html, and css components, it feel I'm strengthen my knowledge on those two(which I'm probably not... I don't know).... I don't even know why I typing this. I guess, I'm hoping for something else to give a feedback on this pulling of the heart.

Is there away to set @keyframe animation with JavaScript? I tried it, but can't seem to get it to work.

Javascript animation works much different than CSS animation. It's possible to alter stylesheets with Javascript, but it's complicated and almost always not worth it, especially for something like animation.

going through the reference area. Wanted to drop a question. I wasn't going to ask this, but it been on my mind. What do you guys think of coffeesscript? And what is coffeScript?

the site and wiki for coffeescript seem to cover your second question

http://coffeescript.org/

http://en.wikipedia.org/wiki/CoffeeScript

 

regarding the first question, I guess it depends. I haven't used it, but then I like Javascript the way it is, good and bad. As a developer, I focus on enhancing the good parts and filtering out the not so good parts. but you can google for blogs and see what the pro and cons are for yourself.

I don't understand that?!?!?!?!? WHAT IS THE BAD PART ABOUT JAVASCRIPT!?!?!?!? ... To me... it's prefect... I guess cause I'm just getting into the program world, and JavaScript alone with a few other language I'm studying.. I don't know much yet to really say that... but still to me, JavaScript is awesome as it is. other language have been built on top of JavaScript; for a lightweight language that's powerful.What about svg's animation? SVG been around a lot longer then canvas, and it just doesn't make sense to me for how choppy the animation is... a least in my browser. Edited by L8V2L

Which one seem more implantable <~~~ AM I using that correctly?

<!DOCTYPE html><html><body><p>Click the button to call the new myMet() method, and display this month's name, using the new myProp property.</p><button onclick="myFunction()">Try it</button><p id="demo"></p><script>Date.prototype.myMet = function() {switch(this.getMonth()){case 0: {this.myProp = "January"};break;case 1: {this.myProp = "February"};break;case 2: {this.myProp = "March"};break;case 3: {this.myProp = "April"};break;case 4: {this.myProp = "May"};break;case 5: {this.myProp = "June"};break;case 6: {this.myProp = "July"};break;case 7: {this.myProp = "August"};break;case 8: {this.myProp = "Spetember"};break;case 9: {this.myProp = "October"};break;case 10:{this.myProp = "November"};break;case 11:{this.myProp = "December"};break; //<~~~ crap, forgot the last break when I sent it.}}function myFunction() {var d = new Date();d.myMet();document.getElementById("demo").innerHTML = d.myProp;}</script></body></html>
or
<!DOCTYPE html><html><body><p>Click the button to call the new myMet() method, and display this month's name, using the new myProp property.</p><button onclick="myFunction()">Try it</button><p id="demo"></p><script>Date.prototype.myMet = function() {if (this.getMonth() == 0){this.myProp = "January"};if (this.getMonth() == 1){this.myProp = "February"};if (this.getMonth() == 2){this.myProp = "March"};if (this.getMonth() == 3){this.myProp = "April"};if (this.getMonth() == 4){this.myProp = "May"};if (this.getMonth() == 5){this.myProp = "June"};if (this.getMonth() == 6){this.myProp = "July"};if (this.getMonth() == 7){this.myProp = "August"};if (this.getMonth() == 8){this.myProp = "Spetember"};if (this.getMonth() == 9){this.myProp = "October"};if (this.getMonth() == 10){this.myProp = "November"};if (this.getMonth() == 11){this.myProp = "December"};}function myFunction() {var d = new Date();d.myMet();document.getElementById("demo").innerHTML = d.myProp;}</script></body></html>
refer to this:http://www.w3schools.com/jsref/jsref_prototype_date.aspIf you ask me, this is like comparing statement two in an for statement;
;i < array.length;
vs
var I=0, n = arry.length; i > n; 
I sent an email to switch it... no pun indented. Edited by L8V2L

The first one is more efficient because it only calls getMonth once, but that is easily fixed in the second version. Switch statements are a little bit more cumbersome when there is only one line to execute.

Animation in Javascript is done by using setInterval() or setTimeout() to manipulate an element's style periodically.

Yes but, those are inefficient <~~~ I know efficient mean work right... so to be inefficient mean that it doesn't work as efficient, but something that work to efficient take up energy and cpu that could be use for other important task action... JSG comment is... confusing me.... um.... um...They say that requestanimtaionframe is better, and I agree for which it was made for as the name imply... so in sense their is only one animation function.

You don't need more than one animation function.

No they aren't. You schedule a function to run at a later time and then let the CPU idle. That's pretty efficient.

No language is perfect. There are just pros and cons.

Perhaps "imprecise" would be a better word.

 

Certainly requestAnimationFrame() has higher accuracy. It's a newer function that isn't as widely supported. For example, IE9 and under won't be able to use it.

for animation purpose I'm speaking on. The window method's setInterval() and setTimeOut(), are good for...I NEED TO LEARN MORE!!!!!! For minor task and interface that want take up much power, or much cpu. Like a nice clock animation, or a cute little background animation. Or a time out animation in a for loop... while loop would better to set it to true, and have the animation run on a set time out. Edited by L8V2L

The match() method returns an array of matches. The first match would be what's outside of the parentheses, all subsequent matches are associated to a pair of parentheses. Since the match of the whole expression is the same as what's in parentheses, the result will be an array of two identical elements.

WebGL is an interface that allows a programmer to have closer access to the computer's graphics chip to perform expensive operations.

... I wonder why wont they have it to where svg use the cpu to speed up it's rendering? I really like it... even know I know only the basic of it. I'm planning to learn(more so become familiar with) xml; the hold section that's on w3s.; to gain more of a understanding of svg. Edited by L8V2L
