Integer Number Ports

This page will explain how to create an input and ouput port of the type Integer

Click this link to see an example of all port types and code examples

Integer ports can hold a single integer like -2 0 10 101
They're useful when you want to have a parameter to access an array by index or don't want to have to use Math.floor on the numerical input.

//strict mode allows us to write cleaner code
"use strict";

//Create a input port of the type value
const inInteger   = op.inInt("Integer in");
//Create a output port of the type value
const outResult  = op.outNumber("Value out");

//when input port changes call the function 'update'
inInteger.onChange = update;

//this function runs every time the input port changes
function update()
{
    outResult.set(inInteger.get());
}
