I have just make an object move continuously and Now I want to make it stop in 10 seconds if the space bar is pressed?
Does anyone know how to implement this in processing? Thank you in advanced!
By default, Processing draws at 60 frames/second, so you can use that to your advantage.
//Global Variables
int countDownTimer = 600 //10 seconds * 60 FPS
boolean spacePressed = false;
void draw(){
if(spacePressed){
countDownTimer--;
if(countDownTimer == 0){
//Whatever happens after 10 seconds here
}
}
}
void keyPressed(){
if(key == " "){
spacePressed = true;
}
}

I'm currently working on a project in which I want an image to pop up after 3 seconds. Once that image has popped up the user has to click on the image to make a "done" image pop up that will disappear automatically after 3 seconds.
I've got most of it working except for the disappearing part. Does anyone know how I can time the image to disappear after 3 seconds?
PImage medic;
PImage medicD;
float time;
float startTime;
final int waitpopup = 3000;
final int DISPLAY_DURATION = 3000;
boolean showimage = true;
boolean showclock = true;
boolean showimagedone = true;
boolean hasClicked;
Clock clock;
void setup (){
size (1080, 1920);
medic = loadImage("medic.png");
medicD = loadImage("medicD.png");
clock = new Clock(width /2, height /2);
time = millis();
}
void draw() {
background (0);
imageMode(CENTER);
if (showclock) clock.display();
if (showimage && millis() - time > waitpopup) {
image(medic, width/2, height/2, 540, 540);
} if (hasClicked == true) {
showimage = false;
image(medicD, width/2, height/2, 540, 540);
} if (millis() > startTime + DISPLAY_DURATION) {
showimagedone = false;
}
}
void mousePressed() {
hasClicked = true;
startTime = time;
}
You can use the millis() function or the frameCount variable to check how much time has gone by, then do something after X seconds or after X frames.
You're already doing some of the work with the showimagedone variable, but you need to use that variable to conditionally draw your image.
I recommend starting with a simpler example and getting that working. Here's one example:
int clickedFrame;
boolean on = false;
int duration = 60;
void draw(){
if(on){
background(255);
if(frameCount > clickedFrame + duration){
on = false;
}
}
else{
background(0);
}
}
void mousePressed(){
clickedFrame = frameCount;
on = true;
}
This code show a white background for one second whenever the user clicks the mouse. You need to do something similar with your images.

I'm trying to build a ping pong game with Processing language. For this two-player game I have two controllers at each end of the 'table'. I coded the movements of the players (up and down) by binding them to the keys:
- w and s for player 1
- o and l for player 2
Although this works when I press them one at a time, I cannot figure out how to make them move simultaneously, as in pressing both w and o at the same time.
Here is my code:
int x=535;
int y=350;
int dx=5;
int dy=5;
int pX=10;
int pY=520;
int pX1=1870;
int pY1=520;
int pS=5;
void setup() {
size(1920,1080);
}
void draw() {
background(0);
rect(960,0,5,1080);
rect(pX,pY,40,150);
rect(pX1,pY1,40,150);
ellipse(x,y,50,50);
x=x+dx;
y=y+dy;
bounce();
move();
move1();
}
void bounce(){
if(x>=1920 || x<=0){
dx=-dx;
}
if(y>1080 || y<0){
dy=-dy;
}
}
void move(){
if(keyPressed){
if(key == 's'){
pY+=pS;
}else if (key == 'w'){
pY-=pS;
}
}
}
void move1() {
if(keyPressed){
if(key == 'l'){
pY1+=pS;
}else if (key == 'o'){
pY1-=pS;
}
}
}
What you want to do is create a boolean value for each key you care about. Then in the keyPressed() function, you set the corresponding variable to true, and in the keyReleased() function, you set the corresponding variable to false. Then in your draw() function, you check the variables to determine which keys are pressed.
Shameless self-promotion: I wrote a tutorial on getting user input available here. Check out the Handling Multiple Keys section.
I've written this code which creates a sketchbook.
I'm sure that there's a simple error, but why won't it stop playing at the end of the images?
Here is the code
import ddf.minim.spi.*;
import ddf.minim.signals.*;
import ddf.minim.*;
import ddf.minim.analysis.*;
import ddf.minim.ugens.*;
import ddf.minim.effects.*;
Minim minim;
AudioPlayer sou; //variable name;
final int NUMBER_IMAGES = 27;
PImage[] images; //sets PImage array
int framerate = 10;
int currentImage = 0;
String getImageName(int image_number) {
if (image_number == 0) { // == double equals checks for equality
return "title.gif"; //missing k0.gif and k26.gif until this line //added
} else if (image_number == 26) {
return "title2.gif";
} else {
return "data/K" + image_number + ".gif";
}
}
void setup () {
minim = new Minim(this); //define construction
sou = minim.loadFile("ambience.mp3");
sou.loop();
size (300, 300);
background (255);
frameRate(framerate);
imageMode (CENTER); // Tells the images to display relative to CENTRE
images = new PImage[NUMBER_IMAGES]; // initialises the array (not images)
for (int image_number = 0; image_number < NUMBER_IMAGES; image_number++) {
String filename; // Declared a String called filename
filename = getImageName(image_number);
images[image_number] = loadImage(filename);
}
}
void draw () {
// Set framerate
frameRate(framerate);
// Draws first image
image(images[currentImage], width/2.0, height/2.0);
currentImage++;
currentImage = currentImage % NUMBER_IMAGES;
}
void keyPressed() {
if (keyCode == UP) { // up arrow increases frame rate by one
framerate ++;
}
if (keyCode == DOWN) { //down arrow decreases framerate by one
framerate --;
}
}
I can't think of more details to add although I'm being told I can't post this as it is mostly code.
This line is the one that achieves the recurrent number loop.
currentImage = currentImage % NUMBER_IMAGES
What the % (Modulo) operator does is to calculates the remainder when one number is divided by another. So lets say for example that your NUMBER_IMAGES is 10, at first you'll have 1 & 10 and the value stored in currentImage would be 1. This continues until you reach 10 % 10 the value stored would be 0 and there you'll start all over again.
Here you can find more about the (Module) in Processing: https://www.processing.org/reference/modulo.html
Perhaps a more simple approach to achieve what you'll looking for would be to add a condition to stop when you reach the number of images.
void draw () {
// Set framerate
frameRate(framerate);
// Draws images
image(images[currentImage], width/2.0, height/2.0);
if(currentImage < NUMBER_IMAGES){
currentImage++;
}
}
Hope this helps.

Because you have this line inside your code it will show images forever
currentImage = currentImage % NUMBER_IMAGES
If you want stop drawing nex image simply change this line into something like this:
if(currentImage == NUMBER_IMAGES) noLoop()
noLoop() will stop whole draw() animation so it will display your last image. If you want then exit the animation you can add this to your keyPressed():
if (keyCode == ESC){
exit();
}
exit() will correctly exit your program. You can use this function instead of noLoop to end after last image.
Hey guys I am in the process of building this simple billiard game, and I want the black ball, labeled bBall, to go the same distance as the white ball, labeled wBall, and no farther. ie, if the white ball travels 20 pixels before it hits the black ball, I want the black ball to travel 20 pixels and then stop. How might I go about accomplishing this? Thanks for the help guys.

float cdistance;
int steps = 40;
void setup(){

background(16,77,27);
wBall = new ball(35,#ffffff);
bBall = new ball(35,#000000);

fill(myColor);
ellipse(xpos,ypos,ballDiam,ballDiam);
}
}
}
void keyPressed(){
if (key =='c'){

One way would be to make your
else if (click==4) {
if (cdistance<bBall.ballDiam) {
moving = true;
bBall.xpos-=difx/steps;
bBall.ypos-=dify/steps;
}
}
to
else if (click==4) {
if (cdistance<bBall.ballDiam) {
if (dist(wBall.xpos, wBall.ypos, bBall.xpos, bBall.ypos) < sqrt(sq(difx)+sq(dify))) {
moving = true;
bBall.xpos-=difx/steps;
bBall.ypos-=dify/steps;
}
}
}
essentially only moving the ball as long as its distance from the white one is less than the original difference...
Despite this though I feel you are approaching this the hard way. Maybe take a look to introduce speed and acceleration (and maybe even friction) calculations to your game and things will make more sense...
Hello everyone I have been following this tutorial here http://www.gogo-robot.com/2011/05/30/xna-skinned-model-animations/ and so far its great got the animations playing and everything, but now I want to expand it and stop the continuous loops say for instance i press the a key to make the model jump when i release the a key i want him to stop jumping but if i hold the a key i want him to keep jumping. Here what i have tried so far
and none of it works.
I am stumped here on how to do this thanks for any help with this.
private void HandleInput(GameTime gameTime)
{
currentGamePadState = GamePad.GetState(PlayerIndex.One);
// Check for changing anims
//SkinningData skinningData = model.Tag as SkinningData;
SkinningData sd = jumper.model.Tag as SkinningData;
if (currentGamePadState.Buttons.A == ButtonState.Pressed)
{
if (jumper.animationPlayer.CurrentClip.Name != "Fire")
jumper.animationPlayer.StartClip(sd.AnimationClips["Fire"]);
}
if (currentGamePadState.Buttons.X == ButtonState.Pressed)
{
if (jumper.animationPlayer.CurrentClip.Name != "DieF")
jumper.animationPlayer.StartClip(sd.AnimationClips["DieF"]);
}
//does not work
if (currentGamePadState.Buttons.X == ButtonState.Released)
{
if (jumper.animationPlayer.CurrentClip.Name == "DieF")
jumper.animationPlayer.StartClip(sd.AnimationClips["Idel"]);
}
if (currentGamePadState.Buttons.Y == ButtonState.Pressed)
{
if (jumper.animationPlayer.CurrentClip.Name != "Idel")
jumper.animationPlayer.StartClip(sd.AnimationClips["Idle"]);
}
//does not work
if (jumper.animationPlayer.CurrentTime == jumper.animationPlayer.CurrentClip.Duration)
{
//set him back to idel
jumper.animationPlayer.StartClip(sd.AnimationClips["Idle"]);
}
I have tried these configuration with no luck in the game
// Starts playing the entirety of the given clip
public void StartClip(string clip, bool loop)
{
AnimationClip clipVal = skinningData.AnimationClips[clip];
StartClip(clip, TimeSpan.FromSeconds(0), clipVal.Duration, loop);
}
// Plays a specific portion of the given clip, from one frame
// index to another
public void StartClip(string clip, int startFrame, int endFrame, bool loop)
{
AnimationClip clipVal = skinningData.AnimationClips[clip];
StartClip(clip, clipVal.Keyframes[startFrame].Time,
clipVal.Keyframes[endFrame].Time, loop);
}
// Plays a specific portion of the given clip, from one time
// to another
public void StartClip(string clip, TimeSpan StartTime, TimeSpan EndTime, bool loop)
{
CurrentClip = skinningData.AnimationClips[clip];
currentTime = TimeSpan.FromSeconds(0);
currentKeyframe = 0;
Done = false;
this.startTime = StartTime;
this.endTime = EndTime;
this.loop = loop;
// Copy the bind pose to the bone transforms array to reset the animation
skinningData.BindPose.CopyTo(BoneTransforms, 0);
}
Can you not attach a bool on the animation clip to tell it to play only once, or an active variable that can be called.
