Hi all,

I need to fill a box with more sphere . For do this operation i want kno which can be the best solution?
I have used Instantiate() in a for cycle, but when i do this all objects collide and go out of the box. i not need mandatory to do this at runtime but i don’t know otheer way.
Can anyone help me?

Thanks

To avoid this collision issue, you could instantiate the objects at the top of the box and let them fall. You could use a grid pattern to instantiate a row of spheres, yield, instantiate another row, yield again, and so on. NOTE: this loop should not be in Update, because it doesn’t accept the yield instruction, but could be in Start - something like this pseudo code:

for (var q = 1000; q > 0; ){
    for (var i = 0; i < 10; i++){
        for (var j = 0; j < 10; j++){
            pos = Vector3(i * sphereDiameter, someHeight, j * sphereDiameter);
            Instantiate(spherePrefab, pos + box.position, Quaternion.identity);
            q -= 1; // decrement counter
        }
        yield; // let Unity breath until next frame
    }
}
