SpawnerCraft for Minecraft 1.11.
SpawnerCraft is a "Nearly Vanilla" mod. This series intends to introduce small gameplay changes into the game to make more things within the game available and convenient, while maintaining balance.
SpawnerCraft allows a player to create their own spawners wherever they wish, while (by default) still requiring the player to find a generated spawner, therefor keeping the element of exploration and reward in vanilla, while adding the possiblility to move spawners (with a bit of work) or even obtain a non-standard spawner that is not available in a survival map normally.
