Collision/Gravity Problem

Hello, my name is Alex.
I m trying to do some simple sh*t but it doesn’t really work properly.
I m trying to stack squares one over another,but when i try to put them on the top of each other, they vibrate, the one that is under the one i m holding with mouse, it’s vibrating, and all the “building” is vibrating,as i approach the square i m holding in the air with my mouse.

ps: when i deactivate the rotation (the Z axis ),it’s not bugging anymore.

my skype: tzigared (add me, i m desperate)
my gmail: almostdead911@gmail.com

ps:in the image, it’s shown how i try to drag the square on the top of others, and the “building” vibrates and fall

update: there is a video in which i show you what its not working,because i don’t really know how to explain better

I suspect they are rigidBody cubes and their box colliders are causing a reaction to the cube you are controlling with the mouse.

i think so, and i don’t know what to do to make it smooth and without that bug.

Try making the mass of the block you are moving to a low amount and the stacked blocks mass much higher so they don’t react as much.

i don’t want to do that,since i want all the squares to be the same,i mean i can put 3-4, or even 6-7,it’s not that the x square needs to be different, they all need to be the same

Just make it the same mass once you have stacked it.

they are all same mass from the beginning,and that’s how it shoud be

So it should not work then.

why shouldn’t it work? you told me to change only 1 square’s mass,but i want all of the squares to have the same mass…because it will be only 1 type of square,not 2:)
