private static final BlockChalkstoneBlockSlab.EnumType[] META_LOOKUP = new BlockChalkstoneBlockSlab.EnumType[values().length]; Am i wrong saying that this array is full of nulls? Try doing this in byMetadata(int meta) in the Enum Class: public static BlockChalkstoneBlockSlab.EnumType byMetadata(int meta) { if (meta < 0 || meta >= META_LOOKUP.length) { meta = 0; } return values()[meta]; }

SuParticle.java -> public SuParticle()... super(world, zSpeed, zSpeed, zSpeed, zSpeed, zSpeed, zSpeed); I think this is the mistake youre looking for... The particle is getting spawned but not at the correct coordinates. Try this instead: super(xCoord, yCoord, zCoord, xSpeed, ySpeed, zSpeed);
