`.setTotalLength()`

Description

This function is used to set a value for the totalLength parameter of an EasyEase Object expressed in seconds.

It receives a float value which should positive and be greater than 0.0 to avoid unexpected results.

Example:

setTotalLength.pde

import easy.ease.*;

EasyEase curve = new EasyEase(this, 5);
EasyEase reference = new EasyEase(this, 1, 2, 2, 0);

void setup() {
    size(600, 400);
    textSize(30);
}

void draw() {
    background(#f1f1f1);
    stroke(#ff0000);
    fill(#ff0000);
    strokeWeight(5);
    float start = 50;
    float stopX = width - 50;
    float stopY = 50;
    float motor = curve.framer(frameCount);
    float refX = constrain(width - mouseX, start, stopX);
    float newTotLength = map(refX, start, stopX, 0, 4);

    curve.setTotalLength(newTotLength);

    float ptCurve_X = curve.linear(motor, start, stopX);
    float ptCurve_Y = curve.inOut(motor, height - 50, stopY);
    ellipse(ptCurve_X, ptCurve_Y, 50, 50);

    text("totalLength: " + String.format("%.2f", newTotLength) + " sec.", 300, 350);

    line(start, 380, stopX, 380);
    line(refX, 370, refX, 390);

    line(50, 20, curve.linear(motor, start, stopX), 20);
}
