Score Crafted

ScoreCrafted adds a simple scoring system to the game. 
The idea is quite simple: you play as usual and earn points (you get points for killing mobs, destroying blocks, placing blocks, crafting, smelting, and other actions).

For example:

Zombie — 10 points
Spider — 10 points
Skeleton — 20 points
Creeper — 30 points
Animal — 5 points
Slime — 5 points
Spawner — 50 points
Points are saved with the player, so they are not reset when you leave the world or server. Points are also displayed on the screen and in the player list.
To check the current number of points, use the /score command, and server administrators can add points using commands such as:
/score add 100
Death can also affect the number of points. Depending on the settings, you may keep them, lose some, or reset them.
