Counter expression

[Declan Smith]

The linear function evaluates the current time and returns a scaled value based on the parameters you have supplied. In this example, when time=0 (startT) the count starts and will start at 0 (beginVal). It will then evaluate, in a linear fashion, the next value to display until it reaches 4 seconds (endT) where it will display 100.

So if you wanted the count to start at 3 seconds and finish at 10 seconds, you would put startT=3 and endT at 10.

The t.tofixed(0) ensures that no digits of precision are displayed. i.e. numbers after the decimal point (you could use Math.floor(t) to achieve the same thing in this instance).

To add a % sign on the end, alter the expression as below.

startT = 0;
endT = 4;
beginVal = 0;
endVal = 100;
t = linear(time,startT,endT,beginVal,endVal);
Math.floor(t) + '%'

[Hamid Rohi-bilverdy]

Thank you sir. Worked as intended.

Btw I tried to type in words instead of values in beginVal and endVal. Offcourse an error occoured. Is it possible to make an espression where the start word and end word can be defined??

[Declan Smith]

If I understand you correctly, you want to display a selection of words rather than numbers? I have modified the expression below to include an array of words. The last line uses the integer number generated by the linear function to select one of the words from the ‘words’ array.

Note that the first element in the array is referenced as ‘0’ and the (in this case) the last one ‘9’. Such that:

words[0] will return ‘One’
words[9] will return ‘Ten’

The endVal in this case is the last reference of you words array you want to display, and the beginVal is the first reference.

words=['One','Two','Three','Four','Five','Six','Seven','Eight','Nine','Ten'];
startT = 0;
endT = 4;
beginVal = 0;
endVal = 9;
t = linear(time,startT,endT,beginVal,endVal);
words[Math.floor(t)]

Once again, thank you and you were spot on regarding, understanding my question. As I really want to learn and understand the same time i can’t figure out the math.floor expression…..

[George Goodman]

math.floor simply means round down. So a value of 1.000001 would return 1 and so would 1.99999999999999999999999999999999999999999999999999999999999999999

“|_ (°_0) _|”

Sincerely,

Hi there, I am not an expressions expert but can tinker a bit with them. I have been searching the threads here for a certain type of counter.

I want the counter to start at 0000 then end at 00032

I have tried a bunch of things but can’t get it to work, The expression I have adds another number for example it starts at 0000 but the goes to 00010

How can I get the expression to not add another number but turn one of the previous “0;s” into my count?

I hope this makes sense lol, basically I want there to always only be 4 number slots and to count up. “0000”

Thanks for your thoughts!

Here is what I am using:

numDecimals =0;
commas = true;
dollarSign = true;
beginCount = 0;
endCount = 23;
dur = 23;

t = time – inPoint;
s = linear (t, 0, dur, beginCount, endCount).toFixed(numDecimals);

prefix = “000”;
if (s[0] == “10”){
prefix = “0”;
s = s.substr(1);
}
;.0

if (commas){
decimals = “”;
if (numDecimals > 0){
decimals = s.substr(-(numDecimals + 1));
s = s.substr(0,s.length – (numDecimals + 1));
}
outStr = s.substr(-s.length, (s.length-1)%3 +1);
for (i = Math.floor((s.length-1)/3); i > 0; i–){
outStr += “,” + s.substr(-i*3,3);
}
prefix + outStr + decimals;
}else{
prefix + s;
}

so this adds the prefix of 2 “00” works fine until I get to 10. I tried the expression on this thread but also does not work right for my needs and not sure how to adjust it.

Thanks for your thoughts!

Try the expression below. Some explanation.

startTime – The time that the counter will start
endTime – The time that the counter will stop
beginVal – The first number the counter will register
endVal – The highest number the counter will count to.
padLength – The number of leading zeros required

startTime = 0;
endTime = 4;
beginVal = 0;
endVal = 32;
padLength=4;
t = linear(time,startTime,endTime,beginVal,endVal);
str = '' + t.toFixed(0);
while (str.length < padLength) { str = '0' + str; } str;

Guys is there anyway to replace the regular font numbers with pictures? ie) comps or psd’s in place of the fonts for the numbers? I have created 0-9 and need to use them (hand drawn). Is there a way to link this to the script?

Thanks a LOT!
