Godot 3.2 Changes to RigidBody2D forces, mass, inertia

jgrauman

Hi,

I just got around to trying out Godot 3.2. It looks great, but all the forces applied to my RigidBody2Ds affect them differently in 3.2 vs 3.1. I have to quadruple the mass of a RigidBody2D for the forces to be roughly similar for one object I tried, and the inertia needs to be upped quite a bit more than that. Rather than trying to track down exactly how much to reduce my forces or up the mass/inertia for every object, does anyone know more about these changes so I can figure out exactly what needs to change? TIA.

Actually, I think it's just that the game runs a lot faster now... I wasn't expecting that much of a performance improvement just from bumping to the next version!

Actually, there was a change. The way inertia is calculated changed. With no change to my code all my inertia values are different...

Strange, I do not remember reading that 2D physics in Godot changed. Looking through the change-log for Godot 3.2, there does not appear to be anything that would suggest changes to how Rigidbody2D nodes work, though maybe I missed it.

I didn't have to alter anything after moving to 3.2. It's also possible that our objects are set up very differently and the changes have been too subtle for me to notice..
