I have recently (About 15 hours ago) launched a ClassiCube server which resembles the Premium gamemode format of survival.Here is one of my admin's recorded videos
The following commands related to SMP are :
/craft block amount_of_blocks_you_want_to_use
Example : /craft log 4
That will craft 4 logs into 16 wooden planks.
/smelt Block_Smelting Block_Burning Amount_of_Blocks_Being_Smelted
Example : /smelt sand log 4
That will smelt 4 sand using 8 logs into 4 glass.
It takes 2 logs to smelt 1 block.
Fall, drowning, and lava damage have been completed.
Known Bugs: Items resetting after disconnect (Solution is known and about to fix it)
Planned: PvP, custom client and applet, and an Mob AI, plus we are working on CPE support
This server was made to increase ClassiCube's popularity, so far we have gotten around 40 new players in 1 night. The server name is [NeonGaming] Survival Server. The software cannot be used publicly but you may contribute to it at https://github.com/NeonGaming/NeonGaming-SMP . Have Fun!!
