addcharacter(index) nothing/error If Index is 0 (.AddCharacter(0)), it will find the next available slot on the account. (Otherwise pass 1-5) Will create a naked, uncolored, male character named 'new character' at 1, 1, 1 on Britannia. No scripts are ran for this method of character creation. Edit this new character via the script creating it.
ban() true bans the account
checkpassword(string pass) boolean/error returns true if 'pass' is the account's password
delete() true/error Delete this empty account.
deletecharacter(integer slot) true/error Deletes character in slot 'slot'. returns error if not character in that slot (1..5)
disable() true disables the account
enable() true enables the account
eraseprop(string propname) true EraseObjProperty for account objects.
get_member(string membername) object, value of member or error Gets the value of the built-in member 'membername'. var objname := obj.get_member("name") is the same as var objname := obj.name
getcharacter(integer slot) true/OfflineCharacterRef gets an OfflineCharacterRef for the character in slot 'slot'. returns error if not character in that slot (1..5)
getprop(string propname) true/error GetObjProperty for account objects.
move_char(string destacctname, integer slot) true/error Move character from this account to destination account. You can use it to flip chars on same account too.

Client
Explanation
Object representing a connected client. The ClientRef is important when having packethooks which are active before characters are selected, when you only have access to the Client and not the Character. Because the ClientRef contains most information that was in the Character before, it becomes redundant to have those methods and properties in the Character and they will be removed in a future release.

SendAreaPacket(int x, int y, int range, string realm) integer/error Sends this packet to all the players in range of x,y. Returns integer number of clients this packet was successfully sent to.
SendPacket(Character) true/error Sends this packet to character.
SetInt16(int offset, int value) true/error Sets an 16-bit (2-byte) value at offset (0-based). If offset is greater than current size, the packet is resized to fit the new data and the encoded size is updated for variable length packets. Resizing is not allowed for fixed-length packets. Automatically converts to Big-Endian.
SetInt16Flipped(int offset, int value) true/error Sets an 16-bit (2-byte) value at offset (0-based). If offset is greater than current size, the packet is resized to fit the new data and the encoded size is updated for variable length packets. Resizing is not allowed for fixed-length packets. Automatically converts to Low-Endian.
SetInt32(int offset, int value) true/error Sets an 32-bit (4-byte) value at offset (0-based). If offset is greater than current size, the packet is resized to fit the new data and the encoded size is updated for variable length packets. Resizing is not allowed for fixed-length packets. Automatically converts to Big-Endian. NOTE: currently there's a compiler problem setting 0xFFFFFFFF, it gets converted to 0x7FFFFFFF. Use multiple SetInt16 or SetInt8 calls for now.
SetInt32Flipped(int offset, int value) true/error Sets an 32-bit (4-byte) value at offset (0-based). If offset is greater than current size, the packet is resized to fit the new data and the encoded size is updated for variable length packets. Resizing is not allowed for fixed-length packets. Automatically converts to Low-Endian. NOTE: currently there's a compiler problem setting 0xFFFFFFFF, it gets converted to 0x7FFFFFFF. Use multiple SetInt16 or SetInt8 calls for now.
SetInt8(int offset, int value) true/error Sets an 8-bit (1-byte) value at offset (0-based). If offset is greater than current size, the packet is resized to fit the new data and the encoded size is updated for variable length packets. Resizing is not allowed for fixed-length packets.
SetSize(int newsize) integer/error Sets the new size of the packet, possibly destroying data if packet size was decreased. Updates the encoded size for variable length packets, not allowed for fixed-length packets. Returns the old size of the packet.
SetString(int offset, string string, int nullterminate) true/error Sets a string value at offset (0-based). If offset plus length of string is greater than current size, the packet is resized to fit the new data and the encoded size is updated for variable length packets. Resizing is not allowed for fixed-length packets. Set nullterminate to 1 if you want to automatically append a 0 terminator.
SetUnicodeString(int offset, array unicode character, int nullterminate) true/error Sets a unicode string at offset (0-based). If offset plus length of string (2*number of members in the array) is greater than current size, the packet is resized to fit the new data and the encoded size is updated for variable length packets. Resizing is not allowed for fixed-length packets. Set nullterminate to 1 if you want to automatically append a double 0 terminator. Unicode strings in eScript are arrays of 2-byte values. See unicode.em for useful functions. CAscZ in basic.em is useful for character sets that use the ascii/ansi standard.
SetUnicodeStringFlipped(int offset, array unicode character, int nullterminate) true/error Sets a unicode string at offset (0-based). If offset plus length of string (2*number of members in the array) is greater than current size, the packet is resized to fit the new data and the encoded size is updated for variable length packets. Resizing is not allowed for fixed-length packets. Set nullterminate to 1 if you want to automatically append a double 0 terminator. Unicode strings in eScript are arrays of 2-byte values.

+ string string concatenates the strings, returns the new string.
[start,length] string 'Substring': returns a new string from the character range between start and length, inclusive. Returns error if index out of range. Ex: var str := "yomama"; str[2,3] would return "oma".
[substr] string/uninit seaches the string for 'substr'. If found, returns the first character of the substring, else uninitialized object.
[substr] := replace_str string finds the first occurance of 'substr' and replaces substr with 'replace_str'. returns the new string.
find(search,[start]) int returns like Find(string, search, start) the index of the first occurance of 'search' after 'start' within str, but unlike the basic.em function the Start parameter is optional if not given it searches the whole string
format(args) string formats a string using the data from args. Accepts the following format: {:x} for hex representation {:o} for octal {:b} for binary Add a # to get notation prefix, e.g.: "{:x}".format(10) -> "a" "{:#x}".format(10) -> "0xa" Parameters can be simple: "You have {} gold coins".format(120) -> "You have 120 gold coins" and are unpacked implicitly by their order: "{} hits {} for {} of damage".format("John", "Bob", 120) -> "John hits Bob for 120 of damage" However you can specify parameters explicitly (first argument is at 1): "You hit {2} for {1} damage".format(120, "John Doe") -> "You hit John Doe for 120 damage" Format allows accessing object members: "Spell {1.spell_name} requires reagents: {1.reagents}".format(struct{spell_name:="Fire Wrath", "Ba, Bm, Ga"}) -> "Spell Fire Wrath requires reagents: Ba, Bm, Ga" Implicit members also work: "{name} you hit level {level}".format(struct{name:="Jane Doe", level:=4}) -> "Jane Doe you hit level 4" Character or item members are accessed the same way: "{1.name}, your shield {2.desc} has {2.hp} hp".format(who, who.shield) -> "Admin, your shield Buckler of Death has 150 hp"
join(array) string returns a string which is the concatenation of the array elements, seperated by str
length() int returns number of characters in the string
lower() string returns like lower(str) the lowercase version and also modifies the str
upper() string returns like upper(str) the uppercase version and also modifies the str
