Dan-Expression for Counting

[Mylenium]

Hi, I’m obviously not Dan, but I’ll give it a try.

start_value=7000;
end_value=13000;
ani_time=30;

diff_value=end_value-start_value;
time_value=diff_value/ani_time;
out_value=time_value*time;

[out_value]

Apply this as usual to the source text property.

Thanks Millenium, but no go. I copied and pasted the expression to the text property and it starts
counting at 0 and ends at 994.00000000 with lots of places following after the decimal.
Dans expression for the money counter is this…

This is an expression for the source text of a text layer that should do the trick. Use a monospaced font or set kerning to 0:

startValue = 64122205;
endValue = 85302264;
dur = 30; //seconds

s = “” + Math.round(linear(time,0,dur,startValue,endValue));
“$” + s.substr(0,2) + “,” + s.substr(2,3) + “,” + s.substr(5,3)

Tom,

Try this:

startValue = 7000;
endValue = 13000;
dur = 30; //seconds

Math.round(linear(time,0,dur,startValue,endValue));

Thanks Dan. It is the same thing I tried when I deleted the last line of the Money Counter you helped me with a while back. The problem is the comma after the 1000s position (ie. 7000 vs 7,000) is gone.
How do you add a comma to the equation…And could you give me a laymans explanation of what the expression is telling AE to do?

startValue = 7000;
endValue = 13000;
dur = 30; //seconds

Math.round(linear(time,0,dur,startValue,endValue));
Thanks!

Oh, you want the comma. I get it now. 🙂

This should do it:

startValue = 7000;
endValue = 13000;
dur = 30; //seconds

s = “” + Math.round(linear(time,0,dur,startValue,endValue));
s.substr(0,s.length-3) + “,” + s.substr(-3,3)

It will only work for values from 1,000 to 999,999

The tricky part of the expession is just converting the number to a string and then manipulating the string (using the JavaScript substr() method) to split the string into two pieces an stick a comma in between. You may need to dig into a javaScript reference to really figure it out.

Yes sir, that did the trick. Thanks for the tip on where I can get info for understanding what substrings are and what it means to split them (And this enthusiasm from someone who still has nightmares about high school math class!).
Your help is truly appreciated.

Hello!

I have a similar question regarding this expression. I would like to add a comma with this expression:

//start

val = effect(“Slider Control”)(“Slider”);
numDec = 2; // digits to right of decimal
numDigit = 0; // digits to left of decimal

if (val < 1000000) sign = "" else sign = ""; s = Math.abs(val).toFixed(numDec); while (s.length < numDigit + numDec + 1) s = "0" + s; sign + s //end Thanks in advance!

[Jason Snell]

Works great, BUT, I need to add another comma because of how great/long the number is, is there anyway you could help? Thanks!

startValue = 0;
endValue = 120000000;
dur = 4; //seconds

s = “” + Math.round(linear(time,0,dur,startValue,endValue));
s.substr(0,s.length-3) + “,” + s.substr(-3,3)

[Dan Ebberts]

This is one way:


startValue = 0;
endValue = 120000000;
dur = 23; //seconds

s = "" + Math.round(linear(time,0,dur,startValue,endValue));
if (s.length > 6)
s.substr(0,s.length-6) + "," + s.substr(-6,3) + "," + s.substr(-3,3)
else if (s.length > 3)
s.substr(0,s.length-3) + "," + s.substr(-3,3)
else
s
