This is a small mod by Enosphorous, that aims to create a more realistic environment around minecarts.In vanilla Minecraft, you can stop a minecart in its tracks by simply standing in the way – it works like this for all mobs. Have you ever gotten frustrated at that stupid sheep who has cut off your path into your mine, sending you all the way back? If so, it’s time for the Killer Minecarts mod. This mod creates a very dangerous environment around moving minecarts.
If a minecart is moving above a certain speed, when it comes into contact with a mob (including players) it will deal a large amount of damage to them and flinging them in a random direction, most likely killing them. This is not so on two occasions: 1) If the entity is a player, that damage is reduced, for the sake of balance. 2) If the entity is a creeper, it will immediately explode in your face. This mod does not add any new items or blocks, and is simply to make minecarts a bit more useful/dangerous.
