 Today we will use [Nukkit](https://cloudburstmc.org/articles/) as software to run our program to calculate the URM, we will also use the [Projectiles](https://minecraft-archive.fandom.com/wiki/Category:Projectiles) entities which have an in-game URM, from the position you launch it to where it lands.
 
+First of all, we make a normal Nukkit plugin, we will make a listener class and use two events "ProjectileLaunchEvent" (called when an entity launches a projectile) and "ProjectileHitEvent" (called when the projectile hits something).
+
+We will use nbt to store two pieces of data, the time at which the projectile is launched (initial time) and the vector from where the projectile was launched (initial position / start).
+
+by calling "onProjectileLaunch", we will save the data already mentioned above.
+
+now for the "onProjectileHit" side, we will do all the calculations.
+
+we get the initial time and the initial position, also the current time and the current position.
+
+### Distance: To calculate the distance, we use the "distance" function of the vector3 class of the start vector.
+
+### Time: To calculate the time, we will do a simple operation, subtract the current time from the initial time and divide it by 1000, since both the initial time and the current time are given in milliseconds.
+
+### Velocity: To calculate the speed we divide the distance between the time
