So this is what is happening, The game keeps stopping because two circles collide with each other, I am trying to prevent that by making sure the ID is the square ID, im trying to allow the circles to collide together and just ignore the collisions but its not doing that, and I dont know how exactly to stop this from colliding with each other and only allow it to collide with the square.
basically I want to stop the circle from colliding with another circle and allow it to collide with the square.
Any help would be great thank you
game.engine.engine class
//collision detection class
iter = p_group.listIterator();
Sprite spr = null;
while (iter.hasNext()) {
spr = (Sprite)iter.next();
//remove from list if flagged
if (!spr.getAlive()) {
iter.remove();
continue;
}
//is collision enabled for this sprite?
if (spr.getCollidable()) {
//has this sprite collided with anything?
if (spr.getCollided()) {
//is the target a valid object?
if (spr.getOffender() != null) {
/*
* External func call: notify game of collision
* (with validated offender)
*/
collision(spr);
//reset offender
spr.setOffender(null);
}
//reset collided state
spr.setCollided(false);
}
}
}
this is where i check for collision in the game class which extends game.engine.engine package.
Game Class
// all the circles were are set up the same, theres four
// circletopleft, circletopright, circlebottomleft
// circle bottom left collides with circle top right

circleBottomLeft.setIdentifier(CIRCLEID_3);

circleBottomRight.position = new Float2(550, h-550);
circleBottomRight.setVelocity(new Float2(10.0f, -9.0f));
//keep ball inside secreen boundary

circleBottomRight.addAnimation(new ReboundBehavior(new RectF

circleBottomRight.setIdentifier(CIRCLEID_4);
addToGroup(circleBottomRight);

//make sure its not touched
if (other.getIdentifier() == SQUARE_ID &&
other.getIdentifier() == CIRCLEID_1 ||
other.getIdentifier() == CIRCLEID_2 ||
other.getIdentifier() == CIRCLEID_3 ||
other.getIdentifier() == CIRCLEID_4) {
stop();
Log.d("Game", "Collided, I collided with something");
if (p_paused) {
Message msg = handler.obtainMessage();
msg.arg1 = 1;
handler.sendMessage(msg);
it keeps stopping when top the two circles collide (417 seconds into the game theres a collision, and it doesnt touch the square. it happens exactly when the circle bottom left collides with circle top right
