Movable mesh not updating physics

[SimonGameDev (ZeSimon)]

Hello, I’m trying to simulate physics between two simple boxes, but I noticed that the physics isn’t updated (the top box doesn’t fall) if the bottom one is moved.
Am I missing something ?

Maybe the top box has already gone to sleep at that point and has it’s physics inactive?

Here is a thread that goes more into detail

Prevent rigid body from falling asleep

This worked for me, thanks!

For now you can add this type of function to the falling cube

Hopefully they will fix this in future updates of unreal that it won’t be needed
