Parameters:

  1. int dataType: The cOffset constants can be used to specify the datatype used for the offset. Integers and floats are 4 bytes long, vectors are 12 bytes long and strings can be of variable length (specified by the 32 bit int preceeding the chars of the string)
  2. (Optional) bool forward: Default: true. Setting this to false will make the file position move back

Moves the file position forward (or backward) relative to the current file position, and by an amount of bytes equivalent to reading the given data type

6.7. xsOpenFile

Returning Type: bool

Prototype: bool xsOpenFile(string filename)

Parameters:

  1. string filename: The name of the file to open, without the .xsdat extension

Opens an existing .xsdatfile in read only mode. After invoking this function, the reading functions can be used to read data from the file. Returns true if the file was successfully opened. In a multiplayer game, the file being read must exist for all players and contain the same data to avoid an out of sync error

6.8. xsReadFloat

Returning Type: float

Prototype: float xsReadFloat()

Reads and returns a float from the previously opened .xsdat file. Note that this function does not check if the value being read is actually meant to be a float, which means the value being read is bit casted into a float regardless of what it originally was. This function also moves the file position forward by 4 bytes

6.9. xsReadInt

Returning Type: int

Prototype: int xsReadInt()

Reads and returns an integer from the previously opened .xsdat file. Note that this function does not check if the value being read is actually meant to be an integer, which means the value being read is bit casted into an integer regardless of what it originally was. This function also moves the file position forward by 4 bytes

6.10. xsReadString

Returning Type: string

Prototype: string xsReadString()

Reads and returns a string from the previously opened .xsdat file. Note that this function does not check if the value being read is actually meant to be a string, which means the value being read is bit casted into a string regardless of what it originally was. This function also moves the file position forward by 4 bytes + the amount of bytes in the length of the string

6.11. xsReadVector

Returning Type: vector

Prototype: vector xsReadVector()

Reads and returns a vector from the previously opened .xsdat file. Note that this function does not check if the value being read is actually meant to be a vector, which means the value being read is bit casted into a vector regardless of what it originally was. This function also moves the file position forward by 12 bytes

6.12. xsSetFilePosition

Returning Type: bool

Prototype: bool xsSetFilePosition(int byteOffset)

Parameters:

  1. int byteOffset: 0 indexed byte offset to determine which byte to read and return from the file

Sets the byte (0-indexed) of the file that the next read function will start reading from.

6.13. xsWriteFloat

Returning Type: bool

Prototype: bool xsWriteFloat(float data)

Parameters:

  1. float data: The float value to write

Writes a floating point number to the previously created .xsdat file. Causes an error if a file hasn't been opened before using. Returns true if the floating point number was successfully written. Floats are written in the 32 bit IEEE 754 format

6.14. xsWriteInt

Returning Type: bool

Prototype: bool xsWriteInt(int data)

Parameters:

  1. int data: The integer to write

Writes an integer to the previously created .xsdat file. Causes an error if a file hasn't been opened before using. Returns true if the integer was successfully written. Integers are written as signed 32 bit numbers

6.15. xsWriteString

Returning Type: bool

Prototype: bool xsWriteString(string data)

Parameters:

  1. string data: The string to write

Writes a string to the previously created .xsdat file. Causes an error if a file hasn't been opened before using. Returns true if the string was successfully written. A string is written to the file in two parts, an unsigned 32 bit integer (indicates the length of the string) followed by that many bytes making up the actual characters of the string

6.16. xsWriteVector

Returning Type: bool

Prototype: bool xsWriteVector(vector data)

Parameters:

  1. vector data: The vector to write

Writes a vector to the previously created .xsdat file. Causes an error if a file hasn't been opened before using. Returns true if the vector was successfully written. Vectors are written as 3 consecutive floating point numbers, one for each coordinate.

7. Ai Scripting

7.1. xsGetGoal

Returning Type: int

Prototype: int xsGetGoal(int id)

Parameters:

  1. int id: The goal id/number to get for the current AI

Gets the goal id/number of the current AI

7.2. xsGetStrategicNumber

Returning Type: int

Prototype: int xsGetStrategicNumber(int id)

Parameters:

  1. int id: The SN to get for the current AI

Gets the SN of the current AI

7.3. xsSetGoal

Returning Type: int

Prototype: int xsSetGoal(int id, int value)

Parameters:

  1. int id: The goal id/number to get for the current AI
  2. int value: The value to set the goal id/number to

Sets the goal id/number of the current AI

7.4. xsSetStrategicNumber

Returning Type: int

Prototype: int xsSetStrategicNumber(int id, int value)

Parameters:

  1. int id: The SN to get for the current AI
  2. int value: The value to set the SN to

Sets the SN of the current AI

8. Functions With Seemingly No Practical Use

8.1. xsAddRuntimeEvent

Returning Type: bool

Prototype: bool xsAddRuntimeEvent(string runtimeName, string functionName, int functionArgument)

Parameters:

  1. string runtimeName: This is the name of the runtime to create the event in. This should be "Random Map" for RMS and "Scenario Triggers" for scenarios. Find which one to use in a general script by using the xsGetMapName(true) function and checking the extension. To use with an AI, set the runtime name to "Expert" and pass the player number as the arg
  2. string functionName: This is the name of a user defined function that takes a single integer argument
  3. int functionArgument: This is an integer argument that is passed to the function given to the argument functionName when this event runs.

A runtime event is called after all the XS code has finished executing but before rules start executing. It calls the function functionName given to it with the functionArgument passed to it as a parameter. For programmers familiar with the terminology, this is basically a way to set a callback. It also returns true if the function name given to it exists, otherwise it returns false. Does not work with built-ins

8.2. xsBreakPoint

Returning Type: void

Prototype: void xsBreakPoint()

This function is meant to add a break point to the execution of XS code for debugging. This used to cause a crash in crash earlier versions of DE.

8.3. xsDumpArrays

Returning Type: void

Prototype: void xsDumpArrays()

This function is supposed to blogs out all XS arrays. Currently, it does absolutely nothing.

8.4. xsGetContextPlayer

Returning Type: int

Prototype: int xsGetContextPlayer()

Returns the current context player ID.

8.5. xsGetFunctionID

Returning Type: int

Prototype: int xsGetFunctionID(string functionName)

Parameters:

  1. string functionName: The name of the function to get the hash of

Returns the hash of a given function. This function has no practical application and is probably for internal usage only.

8.6. xsSetContextPlayer

Returning Type: void

Prototype: void xsSetContextPlayer(int playerNumber)

Parameters:

  1. int playerNumber: The player to set the context player to

In other functions involving a playerNumber argument, the value of the context player is used if -1 is passed as playerNumber to them. xsEffectAmount will use the value of the context player as its player if -2 is passed to it as the player argument.
