javascript - HTML5 Canvas - Making an animated background with falling gold flakes -

-

I am working on a website that demands an animated background I am trying to fall into pieces of gold . In the beginning we tried to use an animated GIF, but it is a very heavy and sluggish way.

This is my first time working with canvas, I definitely would love anyone with more experience to give some input on it.

I found some code as a starting point and repurposed it for my needs. This is where I am present:

To work : I would like to slow down the motion of the falling particles, and I will change my shape to see it through the right circle. If I could get it to appear more realistic like falling gold flex, then it would be ideal. I also need to focus on the performance. Are there any ways to adapt it to run more efficiently?

Is there any shortage of this approach in terms of reach / cross-browser compatibility? I have done some research and it seems that it is widely supported.

Your help will be greatly appreciated!

I do not know whether it has got a chance to complete before, but goes here ....

To change the speed of the falling particles, you will be able to change the size of your fork pen at line 57 and 58 and type the code @vx and @vy Want to edit, something like this: 

  @ Vx = category (0,1) + 8 * xpos-5 @vy = 0.2*@r   
 I found that there is something more 'reliable' by changing DOP (and Y value to compensate):  
  @dop = 0.001 * Category (1,5) @ or = Category (-100, H- @ R2)   
 Regarding creating more 'realistic' snowflakes, I personally like to see the shapes close to "circle" because the  real  flex is hard to see in real life itself. But if you are eager to work on your original idea, then I can tell you.  
 Is there a simple example that you are looking for something simple  Pentaflake fractals  If you really want to throw people's brains away, then I would suggest looking at the source code of this HTML canvas fractal app.  
 I hope this will be helpful :)

excel vba - How to delete Solver(SOLVER.XLAM) code -

-
After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'

I have a UITextView and I change a word like the code at the end of UITextView.text: - (void) Replace TexttechWitWord: (NSString *) word {NSString * currentTextViewText = self.textView.text; CurrentTextViewText = [currentTextViewText stringByReplacingCharactersInRange: NSMakeRange ([self.textView.text length] - [word length], [word length]) withString: word; Self.textView.text = currentTextViewText; } Replacement work is fine, but it runs very slowly and very slowly when the textView now lengthens Is there any better way? I try the replacement range: with text for a week but still stuck. Not to know how to use it to replace it in your case. Please guide! Thanks in advance! This is an important job. As you are using an irreversible string and you are creating a very long string and before Assigned to NSString created from. NSString will be used instead of NSMutableString . - (UITableViewCell *) TableView: (UITableView *) Table View CellForOutPath: (NSIndex...
