updating/removing a string

I have a game which asks you a question if you get three matching images in a row, it then pops up with a question, this question stays on the screen and when they win again the question goes over the top and neither question can be read, is there a way to, on key-press remove the current question?

// images are 720 by 540

String[] questions = new String[4];

// link to answers

boolean overBox = false;

int[] answers = new int[4];

//int[] questions = new int[4];

int numFrames = 6; // The number of frames in the animation

int frame = 0;

changing a color variable to a tint?

I have a color variable to change the color of an object using a keyPress but I wanted to change that object into a Pimage is there a way I could make a tint variable?

color c; // variable to store the current color

void draw() {

// draw ellipse at mouse location with the current color and no stroke

noStroke();

fill(c);

ellipse(mouseX,mouseY,80,80);

}

void keyPressed() {

if (key == 'b') { c = color(0); } // press b to make the current color black

if (key == 'w') { c = color(255); } // press w to make current color white

Running SoundCipher and Minim

I seem to be having a problem, but I can't work out, my code when the mouse hovered would play piano music and this worked fine, I then wanted to add background music over the top which could be controlled with a keypress however adding the background music seems to stop the piano working, any ideas why?

}

ex.playNote(position*4, 60, 1);

playingExample = position;

}

if( mousePressed ) {

} else {

}

// check if note should be played

Starting a timer in an if statement?

I'm trying to make a timer to start only if some conditions are met first however no matter what I do the timer seems to just start count from as soon as I hit run. I need this timer to start in this if statement for my game to work, any help would really help (anything involving the timer I've highlighted in red)

Hi I'm building a slot machine game and am having a few problems I'm pretty new with processing.

I've made this code and need the "wheels" to be random but they all have the same image (vertically)

I realise you won't be able to see the images so here's some links if you want them.

if (keyPressed == true) {

// whats the key is it correct

}

if (i > 400) {

//display times up

}

}

}

// }



I'm also having issues with getting the "winner" (if the horizontal images's pixel in the left hand corner match go onto "winner".

I'd really appreciate any help anyone can offer.

Sounds with a mouse hover

Hi I'm trying to create essentially a keyboard which you can play the keys using a mouse hover (You can't see keys but different areas of the screen are different notes)
I found this online I really can't remember where:

import arb.soundcipher.*;

SoundCipher sc = new SoundCipher(this);

SoundCipher ex = new SoundCipher(this);

SoundCipher bg = new SoundCipher(this);

int t = 0;

int fps = 100;

int adding = -1;

String newPosition = "";

int playingExample = -1;

void setup() {

size(500, 500);

smooth();

frameRate(fps);

// generate piano

for( int i = 3; i < height / 14 - 3; i++ ) {

Key k = new Key(i);

}



bg.instrument(49);

bg.playNote(50, 20, 100000000);

}

void draw() {

frameRate(fps);

background(0);

t++;



// reset timer at full circle

if( t == 361 ) t = 0;



// draw timeline circle

noFill();

stroke(255);

ellipse( width/2 + 25, height/2, 400, 400 );



// draw current position circle

fill( 0 );

ellipse( width/2 + 200*sin(radians(t)) + 25, height/2 + 200*cos(radians(t)), 20, 20 );



// draw info text

fill(255);

text( "Press UP and DOWN keys to adjust speed ("+Integer.toString(fps)+"%).", 10, 20 );

if( adding > 0 ) {

fill(255);

text("Please enter a number between 0 - 360 for the position: " + newPosition, 10, height-5 );

}



}

public class Key {

int position;



Key( int p ) {

position = p;

registerDraw(this);

}



void draw() {

if( mouseX < 50 && mouseY > position*15 && mouseY < position*15 + 15 ) {

if( playingExample != position ) {

if( playingExample >= 0 ) {

ex.stop();

}

ex.playNote(position*4, 60, 1);

playingExample = position;

}

if( mousePressed ) {

fill(150);

adding = position;

} else {

fill(200);

}

} else {

fill(255);

}

stroke(0);

rect(0, position * 15, 50, 15);

}



}

public class Sound {

public int position;

public int pitch;

float x, y;

boolean enabled = true;



Sound( int position_, int pitch_ ) {

position = position_;

pitch = pitch_;

registerDraw(this);

x = width/2 + 200*sin(radians(position)) + 25;

y = height/2 + 200*cos(radians(position));

}



void draw() {

if( enabled ) {

boolean hovering = false;



// check if note should be played

if( t == position ) {

sc.playNote(pitch, 100, 1);

}

fill( pitch*2, pitch*2, pitch*2 );



// check if mouse is hovering above the circle

if( mouseX > (x-10) && mouseX < (x+10) && mouseY > (y-10) && mouseY < (y+10) )

{

hovering = true;

fill(200);

}



// check if mouse is pressed

if( mousePressed && hovering )

{

// remove this item

this.destroy();

}



ellipse( x, y, 20, 20 );

}

}



void destroy() {

enabled = false;

}





}

void keyPressed() {

if (key == CODED) {

if (keyCode == UP) {

if( fps < 150 ) {

fps = fps + 10;

}

} else if (keyCode == DOWN) {

if( fps > 50 ) {

fps = fps - 10;

}

}

}

}

void keyTyped() {

if( int(key) >= 48 && int(key) <= 57 ) {

if( adding > 0 && newPosition.length() < 3 ) {

fill(255);

newPosition = (String)newPosition + (String)Integer.toString(int(int(key) - 48));

}

} else if( int(key) == 10 ) {

newPosition = Integer.toString(Integer.parseInt(newPosition) % 360);

new Sound( int(Integer.parseInt(newPosition)), int(adding*4) );

newPosition = "";

adding = -1;

}

}

Like the keys on the left I don't know how to code the size of the area the sound is, if that makes sense, any help or examples would be appreciated.

Following the mouse and key presses

[2 Replies]

Basically I had this code originally:
void setup() {
size(1080, 720);
}

void draw() {

if (mousePressed) {

fill(255);

} else {
fill(0);

}
noStroke();
ellipse(mouseX,mouseY,80,80);
}

Which makes the ellipse follow the mouse and stay on the screen I want this but the colours to be controlled through key presses rather than the mouse (I'm playing with speech software and motion controls so I can't have mouse click)

So I wrote this code:

// Click on the image to give it focus,

// and then press any key.

int black = 'b';

int white = 'w';

void setup() {

size (1600, 700);

}

void draw() {

fill(black, white);

}

void keyReleased() {

if (key == 'b') {

black = 0;

} else {

black = 255;

if (key == 'w') {

white = 255;

} else {

white = 0;

}

}

noStroke();

ellipse(mouseX,mouseY,80,80);

}

Which works with the key released (again can't be pressed because of voice software) and only places a ellipse where the mouse is rather than making a continuous line of them follow the mouse, any ideas how I could fix this?

Any help would really be appreciated.

Changeing a point into an elipse

Hopefully a simple question but I have this code for hand tracking and I'm trying to make it into a painting game, a good place to start would be able to change the point into a ellipse so I have control over the size colour and I guess this has a decay rate?
This code is an example from the openNI library called Hands3d

I'm new at code so I'm trying to work out what does what in the code.

Kinect Blob tracking

[4 Replies]

- Forum: Integration and Hardware
Hello I am very new to processing and am basically trying to use blob tracking to make an interactive painting game. My main issue is I can't get any blob tracking to work, the only thing I've got to work is SimpleOpenNI and Blobscanner (blob scanner keeps saying no capture device connected to computer even though simpleopen NI can see my kinect camera.

Any way my question is can anyone help? how do I get Blobscanner to register the kinect or can I add tracking points to the depth in simpleOpenNI I have almost no coding knowlege so an example of this made would be very appreciated.

Side note I'm running on windows,

Thanks in advance.
