- Addition / Subtraction: [?]
You can also add and subtract a value to/from the counter using the add and subtract methods:
myCounter.add(567);
myCounter.subtract(567);
- Set Value: [?]
You can manually set the value of the counter at any time using the setValue method:
myCounter.setValue(12345);
- Increment To: [?]
You can set the counter to increment to a value using the current pace and inc values by using the incrementTo method:
myCounter.incrementTo(12345);
- Smart Increment To: [?]
You can also let the counter figure out the best pace and inc values using a ‘smart’ increment technique.
myCounter.incrementTo(12345, 10, 400);
The above code would tell the counter to increment to 12,345 over a period of 10 seconds. I’ve also set a desired pace of 400 for the animation, but that will change when neccessary to optimize the animation.
Click the ‘Run smart increment example’ button to see a demo of this method in which the counter will increment to 4 different values, each with a duration of 10 seconds, dynamically adjusting pace and inc for optimal results.
