Ive just started with andEngine the past week and i only started learning java/android 3 weeks.

I can use a for loop to add multiple sprites to the screen but when i try to check collisions on them it only does it to one and not the rest.

I want to be able to add a specific number for sprites made from the same texture to the scene, add collision detection to them and also make them slide across the screen (im making a game where you avoid the obstacles).

My simple code:

private void createobstacle(float pX, float pY) {

    obstacle = new AnimatedSprite(pX, pY, this.mObjTextureRegion.deepCopy(),     getVertexBufferObjectManager());
    obstacle.setScale(MathUtils.random(0.5f, 3f));
    scene.attachChild(obstacle);
}

private void createobstacle(int num) {
    for(int i=0; i<=num; i++ ) {
        final float xPos = MathUtils.random(30.0f, (CAMERA_WIDTH - 30.0f));
        final float yPos = MathUtils.random(30.0f, (CAMERA_HEIGHT - 30.0f));
        createobstacle(xPos, yPos);
    }
}

Ive read about arrays but i cannot find any tutorials about anything im stuck with.

Any help would be great!
