How do I stop a physics object in the middle of the air?

i have had this problem for weeks that no matter what i do doesnt work.

in the project,this object is supposed to stop at a specific height.

i tried disabling the physics behavior,enabling immobility and to try out using solid behavior to try to stop it but no matter what i do,it falls.

Do you check the Y position like this: Object.Y = 100 ?

If you do this - it won't trigger because Y will never be exactly 100, so you need to check if Y is between two values, kind of like: Object.Y > 90 and Object.Y < 110

thx,it worked
