save [filename]

• Save the game to a file.

load [filename]

• load the game from a file.

Note:
Normally save and load can only be executed by the server itself, but you can use 'set unsafe true' to get around it. Notice that it is dangerous to let remote user access to your filesystem.

fill [Status] [A x,y] [B x,y optional]

• Status: [0] Empty [1] Wall
• Fill the area from A to B as the given Status.
• B defaults to the same as A
• e.g. fill 1 0 0 10 10 | fill 1 0 0

tp [A id] ([B id] or [B x,y])

• Teleport A to B
• A should be alive, and there should be space around B.
• e.g. tp 0 1 | tp 0 1 1

revive [A id optional]

• Revive A.
• Default to revive all tanks.

summon [n] [level]

• Summon n tanks with the given level.
• e.g. summon 50 10

kill [A id optional]

• Kill A.
• Default to kill all tanks.

clear [A id optional]

• Clear A.(only Auto Tank)
• Default to clear all auto tanks.

clear death

• Clear all the died Auto Tanks
  Note: Clear is to delete rather than to kill, so the cleared tank can't revive. And the bullets of the cleared tank will also be cleared.

set [A id] [key] [value]

• Set A's attribute below:
• max_hp (int): Max hp of A. This will take effect when A is revived.
• hp (int, < max_hp): hp of A.
• target (id, int): Auto Tank's target. Target should be alive.
• name (string): Name of A.

set [A id] bullet [key] [value]

• hp (int): hp of A's bullet.
• lethality (int): lethality of A's bullet. (negative to increase hp)
• range (int): range of A's bullet.
• e.g. set 0 max_hp 1000 | set 0 bullet lethality 10
  Note: When a bullet hits the wall, its hp decreases by one. That means it can bounce "hp - 1" times.

set tick [tick]

• tick (int, milliseconds): minimum time of the game's(or server's) mainloop.

set msgTTL [ttl]

• TTL (int, milliseconds): a message's time to live.

set longPressTH [threshold]

• threshold (int, microseconds): long pressing threshold.

set seed [seed]

• seed (int): the game map's seed.

set unsafe [bool]

• true or false.

WARNING:
This will make the remote user accessible to your filesystem (through save, load).
