Hello, thanks for the reply!
So i read the description of the command SetPhysicsScale and it seems to be one important key in order to understand what is going on. I also looked into the notice you made. My first thoughts were that when the virtual resolution is scaled down and the physics scale remains the same, then the new screen in the physics system is less in meters x meters (width x height ) and with the same force an object will travel from the one side of the screen to the other faster not because the force is greater but because the object has to travel less meτers.
Yet i have some questions about the function createphysicsforce i cant answer. Need to study more
