processing

问题 I am researching how to play alpha videos in processing to make augmented reality. What is the format and encoding needed to render video files with alpha channel? When I do this in Unity I use a special shader and video format so can use luma cut, whereas in the same video you put the white and black in one side (or up) and the color in the other side (or down), then the shader makes "the magic" and leaves the color over to cutted image. Here is a link to previous post: Video with alpha

问题 I have to view the side of the cube when pressing the key: • The user sees different views of the cube when presses the following keys: • The 1 key: the front view of the cube (red face) • The 2 key: the back view of the cube (yellow face) • The 3 key: the top view of the cube (blue face) • The 4 key: the bottom view of the cube (magenta face) • The 5 key: the right view of the cube (green face) • The 6 key: the left view of the cube (cyan face) I have the code. It works without the answer;

问题 Is there a way to disable the window's close button in Processing, during a certain event? Here is a snippet of the code: frame.addWindowListener(new WindowAdapter() { public void windowClosing(WindowEvent we) { if (youWin == 0) // condition that is supposed to keep the application opened { JOptionPane.showMessageDialog(frame,"You can't exit until you finish this game. OK?"); // keep applet opened } } } ); EDIT: I want to do it without using JFrames. 回答1: Edit: This answer is for Processing 2

问题 Im getting this error for processing, when I use Twitter4j 3 and processing 2. Ive tried browsing the error, but no one has resolved it. When ever I run my program for a period of time(30 seconds), it halts and gives this error. Im using the streaming API in my code. Im running processing on a MacOSX. EDIT**** Here is my code so far... void setup() { size(600, 600); smooth(); noStroke(); } void draw() { GetTweets(); } void method1() { System.out.println("method1 can be called and it works!!")

问题 I'm trying to generate a grid of points from its 4 corners. As this corners can be freely placed, it will look as the grid has a perspective. I've written the following code in Processing, where corners are in clockwise order (starting at top-left) PVector[][] setGrid(PVector[] corners, int cols, int rows) { PVector[][] grid = new PVector[rows][cols]; for(int y = 0; y < rows; y++) { float fY = (float)y / (rows - 1); PVector p1 = PVector.lerp(corners[0], corners[3], fY); PVector p2 = PVector

问题 I've created some nested arrays to display array of Images, one thing I cant get right it repeats the same image instead of drawing a new one in every loop. here is my example code simulates my problem var images = []; function preload() { for (var i = 0; i< 3; i++) { images[i] = loadImage("img/img" + i + ".jpg"); } } function setup() { createCanvas(900, 900); background(0); preload(); } function draw() { //image(images[0],0,0); for ( var y= 0; y < height; y=y+300) { for ( var x =0; x < width

问题 I will keep this short, I am making a Tower Defence game as a mini project while I have some spare time and I am trying to figure out how I can implement the towers to be able to shoot the enimies when they come into range using dist but I just don't know how to implement a method that uses the enimies position and the towers position. I have an ArrayList of CreepSprites and Towers CreepSprite[] CreepSprites; ArrayList<Tower> AllTowers = new ArrayList<Tower>(); ArrayList<Creep> AllCreeps =

问题 I am working on a tile based game, where various tiles have different states. I am now looking to add a player object, this object will continually check the states of the tiles in order to move. My Tile class: class Tile { int x, y; boolean empty = true; boolean baseCell = true; boolean active = false; public static final int EMPTY = 0; public static final int BASE = 1; public static final int ACTIVE = 2; Tile(int x_, int y_, boolean baseCell_) { x=x_; y=y_; baseCell=baseCell_; } void

问题 Following the collision between a ball from an array and an object (rectangle), the ball doesn't seem to have the same bounce affect as it has when it hits the ground. When coming into contact with the object, it seems to pick up speed and suddenly glitches through and comes to rest on the ground. Questions: Why does it seem to want to rest on the ground and not on the object itself? How can I make the ball have the same bounce affect when coming into contact with the object as it has when

问题 Solution: Start Processing 64 bit mode (Mac: in Preferences). Sketch/Import Library/Add Library (All the libraries are there: Thank you Processing Team !!!) Install what you want (I took Opencv for processing). Works. Enjoy :) Original Question: I have OpenCV installed on my system. Finally after a lot of fails and a complete new system install. Now I saw that there is this Processing OpenCV library: http://ubaa.net/shared/processing/opencv/ Which is awesome and it comes with a Mac installer
