Thanks for reporting this.
I assume you have some kind of script in your video that’s changing those parameters on dragStart and dragEnd?
You are correct that these are not being updated, and your request seems perfectly reasonable; and now that you mention it, potentially very useful for interesting gameplay.
Isn’t this the default behavior? You shouldn’t need to change anything in this case. If you mean click and hold for a few seconds for example, you should be able to add a constraint function to pause the movement for a few seconds
Edit: I don’t think I understood the issue; being able to modify the properties and it not updating definitely seems like a bug.
I’m not sure the original intent, but if you wanted to, say, allow a player to become ‘stronger’ the longer they pushed something, this would let you do it, which seems neat.
