Multiple audio samples with minim

[5 Replies]

Hello all!

I'm currently writing a program that's basically a grid sequencer, and I had an audio question. Currently, my program can detect "hits" by displaying fill colors, but I'd like a variable audio sample (one of 16) to play depending on the position of the tile. I have my program split up into three different classes: Timer, Column, and Tile. It works by passing timing and placement information into an array of the Columns, which is made up of an array of the Tiles. I based my audio integration off of the following doorbell tutorial: http://www.learningprocessing.com/examples/chapter-20/example-20-3/

I was able to get it so a single sound played any time a tile was clicked, but whenever I tried to load a second sound I got an out of memory error. I should have plenty of memory for two data sounds, so I'm guessing I made a mistake somewhere along the line, and I'd appreciate someone taking a look at it. Thanks!

Question about collision

Hello, I'm currently working on a project that requires a grid to be laid out across the sketch, the user click on different tiles of the grid, and then a line moving across the screen be able to interact with only the clicked objects. I was wondering what the best way to go about this would be? Here's the code I have so far, it's just a column of the tiles instead of the full grid:

Tile [] tiles;

int spacer = 100;

color c = color(170, 170, 170);

void setup() {

size(400, 400);

tiles = new Tile[4];

for (int i=0; i < 4; i++) {

tiles[i] = new Tile(0, spacer*i, spacer);

}

}

void draw() {

background(255);

for (int i = 0; i<tiles.length; i++) {

tiles[i].display();

}

}

void mouseReleased() {

for (int i = 0; i<tiles.length; i++) {

Tile tile = tiles[i];

if (mouseX > tile.x &&

mouseX < tile.x + tile.w &&

mouseY > tile.y &&

mouseY < tile.y + tile.h) {

tile.pressed = !tile.pressed;

}

}

}

/////////////////Tile Class

class Tile {

int x, y, spacer;

boolean pressed;

int w, h;

color c = color(170, 170, 170);

Tile(int tempX, int tempY, int tempSpace) {

w = tempSpace;

h = tempSpace;

y = tempY;

x = tempX;

}

void display() {

fill(c);

rect(x, y, w, h);

if (pressed) {

c = color(170, 170, 0);

}

else {

c = color(170, 170, 170);

}

}

}
