Can I define a property within an object prototype (method)?

由 ℡╲_俬逩灬. 提交于 2021-02-05 09:10:28
问题 Question part 1: I've made an object constructor with properties in it, but I am wondering if I could define another property of the object within one of it's methods. For example: var Player = function(p1) { this.property1 = p1; this.property2 = 0; } then, can I define this.property3 in a method, like: Player.prototype.drawMethod = funtion() { this.property3 = 1; } and have it accessible, like: var obj = new Player(true); if (obj.property3 ===1 && obj.property1 === 1) { //code } else { obj

问题 I am using an npm, webpack, babel environment to write an application with p5.js. To be able to have the sketch as a module, I have the sketch in instance mode and import the library and add-ons as modules: import p5 from 'p5'; import 'p5/lib/addons/p5.sound'; import 'p5/lib/addons/p5.dom'; Then I load them to the window inside my sketch: const sketch = (p5) => { window.p5 = p5; ... } new p5(sketch); When I try to use: amp = new p5.Amplitude() I get a 'p5.Amplitude is not a constructor' error

How to run Processing+Twitter4j sketch in broswer

由 北慕城南 提交于 2020-01-11 11:17:48
问题 I'm a newbie programmer practicing Processing and I recently developed a sketch that uses Twitter4j. When I run the sketch in Java mode from the Processing Development Environment it works perfectly. Also, when I export the sketch from Java mode the resulting application runs perfectly. However, when I switch to JavaScript mode and try to run the sketch the browser preview does not display anything. I believe the problem is related to Twitter4j because when I remove the Twitter4j-related code

由 亡梦爱人 提交于 2020-01-01 03:57:05
问题 I'm writing a processingjs script that I want to resize depending on the users viewport width. As far as I know there's no functionality for this in processing, so I've been looking at JQuery and using $(window).width(); . Only I don't know how to get that value into the size(width, height) function in processing. Any ideas? Thanks Links if you need them: http://processingjs.org/ http://api.jquery.com/width/ 回答1: You can call $(window).width(); in the size function. Mixing js and p5 code is

问题 This is a follow-up of my question: Make the cursor a self-drawn image. I have a paint a picture application.

I want there to be a better user experience, so I am trying to draw the eraser

Make the cursor a self-drawn image

问题 I have a paint application program I have programmed from scratch in processing.js and incorporated it into my markdown code on my GitHub page. This means I would prefer to not use CSS (I would have to link to a JavaScript program that creates a link element to the CSS file and appends it to the head). In the paint program, there is an eraser that just paints the background, but I want it to look more like they are using an eraser by changing the cursor to the eraser when they have the eraser
