#### WIGGLE LOOP ####
```
freq = 1;
amp = 110;
loopTime = 3; // loop time in seconds
t = time % loopTime;
wiggle1 = wiggle(freq, amp, 1, 0.5, t);
wiggle2 = wiggle(freq, amp, 1, 0.5, t - loopTime);
linear(t, 0,  loopTime, wiggle1, wiggle2)
```
#### WIGGLE LOOP on 1D for 2D params ####
Add this line to end of wiggle loop code:
```
w = linear(t, 0,  loopTime, wiggle1, wiggle2);
[w[0], transform.position[1]]
```

#### WIGGLE TRANFORM SHAPE ####
set wiggles per second to 0\
Temporal Phase:
```
wigglesPerSecond = 1.5;
loopTime = 3.5;
Math.cos(degreesToRadians(360*time/loopTime))*360*wigglesPerSecond + value;
```
Spatial Phase:
```
wigglesPerSecond = 1.5;
loopTime = 3.5;
Math.sin(degreesToRadians(360*time/loopTime))*360*wigglesPerSecond + value;
```
#### SCROLLING FX ####
Offset FX 
Shift Center To ( create two keyframes )
```
posterizeTime(3);
loopOut("continue")
```

### Format Text
Format text to fixed numbre of decimals.
```
numSlider = thisComp.layer("Loading_BAR").effect("Loading Bar %")("Slider");
textString = parseFloat(numSlider).toFixed(1) // number of decimal points
textString + " % "
```

Format text , Padding + decimal number.
```
numSlider = thisComp.layer("Loading_BAR").effect("Loading Bar %")("Slider");

decimals = 1;    // number of decimal points
minDigits = 3;   // total number of digits BEFORE the decimal point (padding)

value = parseFloat(numSlider);

// build the string with fixed decimals
textString = value.toFixed(decimals);

// split into whole + decimal parts so we only pad the left side
parts = textString.split(".");
whole = parts[0];

// pad the whole-number part with leading zeros
while (whole.length < minDigits) {
    whole = "0" + whole;
}

// reassemble
padded = (parts.length > 1) ? whole + "." + parts[1] : whole;

padded + " % ";
```
