Test capx:

In this capx, I try to set the same mass by setting density, then applying a force.

You could toggle "wait 0.1" to see the different result.
- With "wait 0.1", the mass of these two object is the same, so they move with the same velocity.
- Without "wait 0.1", the density would not be changed, so they move at different velocity.

I think its because when you change the density Construct destroys the body and recreates it with the new density, so there is bound to be a slight delay before the new body is created and usable.

So without the "wait 0.1" the force is applied to the old body with the old density, and with the "wait 0.1" its applied to the new body with the new density.

Agree.

Users might think the 'set density' is buggy since they don't know this trick (wait 0.1).

One solution is put a notify into manual.
