This package simply provides one function: GetPlayerTotalVelocity
which returns the players velocity in kilometres per hour.
The exact formula for this has quite a lot of history and debate centered around it in the SA:MP community. There is a discussion on the topic here.
Despite the many different methods people have come up with over the years, this library currently just employs a very simple multiplier of the vector of the player's velocity.
Simply install to your project:
sampctl package install ScavengeSurvive/velocity
Include in your code and begin using the library:
#include <velocity>
To test, simply run the package:
sampctl package run
And connect to localhost:7777
