Ah so it's good for say as an example changing the default move speed of the player when on food at changing the speed of the player when in a vehicle kinda scenario?
Since acceleration isn't part of this plugin- would you consider that an option?
With update 1.01, vehicles can have their speed values changed too. You can momentarily change their default speed set in the parameters using Plugin Commands.
Unfortunately, I will not include acceleration in this plugin. It would make things much more complex and I want to keep it simple.
