Ratio 12 segment

Former Member over 5 years ago

Hi gentlemen.

I'm sorry to start this thread, but I need help with this feature:

I divided the Circle into 12 segments and every 5 seconds I fill in one segment, a total of 60 seconds = 1 minute. The problem is that my last segment is not filling up. Please advise where there may be a mistake?

I enclose an example of a function, including an error.

Thank you for your help

function drawCircle(dc) {
  	    var handWidth = dc.getWidth();
    	var position = System.getClockTime().sec /5; RATIO;
    	dc.setPenWidth(handWidth/18.3);
    	
    	for (var i = 0; i < 12; ++i) {
    
        if (i < position)
    	{
    		
    		dc.setColor(Graphics.COLOR_BLACK, Graphics.COLOR_BLACK); 
    	   
    	}
    	else
    	{
			
			   	
    	    dc.setColor(Graphics.COLOR_LT_GRAY, Graphics.COLOR_BLACK);
    	}		 
	
 
    	   var start = 360 - ( 4 + (30*i)); 
    	   var end = start - 21.1;
    	   dc.drawArc(handWidth/6.2, handWidth/2.47, handWidth/10.5, 1, start+90, end+90); 
  	    }
    
          }

I only took a quick look at the code and didn't test it. But I noticed the incrementing in the loop ++i . That means the loop runs only 11 times.

Try instead i++

Hello, thank you but i ++ doesn't work, nothing changes.

OK, next try

var position = (System.getClockTime().sec /5).toNumber();

The next attempt does not change anything and the last segment is not loaded.

Hi,

For me, that is logic That the last segment does not turn on.

If I follow your logic the first segment turns on when 5 seconds is passed because for exemple 3sec/5 =0. So the last segment can only turns on if sec=60 which That never happens

Is this done in onPartialUpdate? If so, that's not called at the top of the minute. onUpdate is.

As I understand it:
position may be 0...11 (with using toNumber()) and
i may be 0...11 (with using i++)

if (i < position) the arc is drawn in black
if (i >= position) the arc is drawn in gray

This means that there are 12 arc's possible. May be start and end should also be adjusted. The logic of var start = 360 - ( 4 + (30*i)); isn't clear for me.

The best way to solve this is debugging with an IDE as you can see what happens.

When you copy the source code to the SW. , so you understand what it is: var start = 360 - (4 + (30 * i));.

I just have 12 segments as a pattern, which are gray. One is filled every five seconds, 5x12 = 60 seconds.

When I adjust it this way, the last segment is filled in, but it's not completely accurate...

var position = (System.getClockTime().sec /4.9).toNumber();

Shent-Aurkhan (SHN) over 5 years ago in reply to Former Member

As I explained 0:0:59 + 1 sec = 0:1:0, 60 never happens.

Completly in accurate if you do ide by 4.9.

What you could do is to fill the last from 0 to 5 sec but the segment will never be all empty

Former Member over 5 years ago in reply to Shent-Aurkhan (SHN)

The logic will be that 60 seconds will not be enough for me to fill in 12 segments, so if I change the value to 4.9, the last segment will be filled in as well. Or I'll just make 11 segments ...
