I have this kind of code in a .js file, referenced from the .qml file:
var aliens = new Array(10*5);
//Create all aliens and position them on the board in rows
function createAliens() {
//Row 1
component = Qt.createComponent("alien1.qml");
var y = topline.y + topline.height + Sizer.alienYGap();
for (var i=0; i<10; i++) {
aliens[i] = component.createObject(board);
aliens[i].x = ((aliens[i].width + Sizer.alienXGap()) * i) +
Sizer.alienXGap();
aliens[i].y = y;
aliens[i].objectName = "alien_" + i;
}
etc etc etc
}
and then i might want to check a collision against all items in the array:
function checkBulletAlienCollision()
{
//Loop over each alien, checking if the bullet intersects
for (var i=0; i<50; i++) {
if (bullet && aliens[i]) { //Check if objects exist first
if (bullet.x > aliens[i].x && bullet.x < aliens[i].x +
aliens[i].width) {
if ((bullet.y > aliens[i].y || bullet.y +
bullet.height > aliens[i].y) && bullet.y < aliens[i].y +
aliens[i].height) {
playSound("killed");
score += aliens[i].pointsAwarded;
scoretext.text = "Score: " + score;
bullet.y = -bullet.height; //Move the bullet offscreen
explosion.x = aliens[i].x - (explosion.width -
aliens[i].width) /2;
explosion.y = aliens[i].y - (explosion.height -
aliens[i].height) /2;
aliens[i].destroy();
aliens[i] = null;
explosion.play();
if (alienanimation.interval >
100) { //Get faster when a alien is killed
alienanimation.interval -= 10;
}
break;
}
}
}
}
}
