UOAssist API

UOAssist API (UOA API)

Razor supports the UO Assist API to allow basic integration into Razor. This information was pulled from here. It has been slightly modified for formatting purposes.

Messages Received

Messages that Razor will process (WM_USER = 0x0400 or 1024)

Request Data (WM_USER+200)

This is used to register your application with Razor. Once your application is registered Razor will begin sending your application the messages described below.

Note

If you have registered a window and wish to unregister just send the message with the window handle again.

Count Resources (WM_USER+201)

This will prompt Razor to begin counting resources.

  • Parameters: NONE
  • Returns 1 on successful start or 0 on stop.

Note

If resources are already being counted the count will be stopped.

Currently it will always return 0 - this MAY be changed in the future but for now it will be zero

Get Coords (WM_USER+202)

Gets the current location of the character.

Note

You MUST use SendMessage for the return value to be valid.

Get Skill (WM_USER+203)

Gets the current skill level of specified skill.

  • Parameters: WPARAM = skill number ( 0 based ) LPARAM (when 0 the return will be the 'display' value, when 1 it will be the 'base' value, 2 = get lock value, 3 = get skill name ).
  • Returns: Skill level * 10. Meaning if the skill level was 19.4 you would get 194 returned. Or if lock value was requested the return is 0 = up, 1 = down, 2 = locked. If the skill name is requested the value is a global atom that you will need to free.

Note

You MUST use SendMessage for the return value to be valid.

Get Stat (WM_USER+204)

Gets the stat and its related attribute.

  • Parameters: WPARAM = stat to get (str = 0, int = 1, dex = 2, weight = 3, 4 = Max HP, 5 = tithing points)
  • Returns: Requested stat (str,int,dex, weight, max hp) in the loword and (hp,mana,stam, max weight, current hp) in hiword. You MUST use SendMessage for the return value to be valid.
Set Active Macro (WM_USER + 205)

Tip

This is not enabled in Razor

Sets the active macro

  • Parameters: WPARAM = macro (zero based 0-7)
Play macro (WM_USER+206)

Plays/Stops active macro

  • Parameters: None
  • Returns: 0 - macro stopped 1 - macro playing
Display text (WM_USER+207)

Displays text on the game screen

  • Parameters: WPARAM loword = color hiword = (0- over characters head 1- system message) LPARAM = global atom that contains string - Razor frees the atom after using it (See Windows SDK on ATOMS)
  • Returns 0 - failure either the user isn't logged in or the atom wasn't found, 1 - success

Tip

Razor will only read strings 255 characters or less, I didn't actually test to see if uo can handle strings that long so if you plan to use long strings you should test that out first.

Request house/boat information (WM_USER+208)

Requests the information on house(s)/boat(s) in the nearby area.

  • Parameters: None
  • Returns: 0 - failure (not logged into game) 1 - success

Tip

You should make sure you are set to receive updates from Razor first.

Add command line command (WM_USER+209)

Add a command line command to Razor. When the user types the command (prefix is '-') you can receive a notification and the parameters the user enters using this feature. For example if you add the command 'broadcast' and the user types in '-broadcast run away' your window will receive a message with 'run away' as the parameters (in a global ATOM).

  • Parameters: WPARAM - HWND of the window to receive the message. LPARAM - ATOM of the command (NOTE: spaces won't work correct)
  • Returns On failure 0 - All command space has been used, 1 - the command ATOM was not found (must be a global atom)
    • On success - returns the value of the message your window will receive (should be >= WM_USER + 400). The message you will receive will be like this:
      • MessageID = return value from add call (remember to use SendMessage)
      • WPARAM = NULL - either a global atom couldn't be create or no parameters were entered
      • or a global ATOM that contains the parameters (You must delete the ATOM yourself)(See Windows SDK on ATOMS)

Tip

Commands are not case sensitive. If you add a command '/command' the user will have to type -/command in order for you to get the message. To remove a command send the command again with a zero as the WPARAM.

Get User ID (WM_USER+210)

You must use send message on this one. It returns a ID that Razor can use to identify the user (NOTE: it is not the actual user ID used by the servers). This is used to add a player to your party.

  • Returns 0 if no user is logged in or a value if a user is logged into the game.
Get Shard Name (WM_USER+211)
  • Returns 0 if no user is logged into the game or if a global atom could not be created.
  • Returns a global atom with the shard name in it.

You must use SendMessage for this message.

Add user to party (WM_USER+212)
  • Parameters: WPARAM - User ID obtained from Get User ID message.
  • Returns 0 on success, 1 on error (will not work if a macro is playing) You must use send message if you want the return value.
Get UO window handle (WM_USER + 213)
  • Parameters: None
  • Returns the HWND of the UO window. NOTE - you must use SendMessage to get the correct value.
Get poison status (WM_USER + 214)
  • Parameters: None
  • Returns 1 if poisoned or 0 if not poisoned. NOTE - you must use SendMessage to get the correct value.
Set skill lock (WM_USER + 215)
  • Parameters: WPARAM = zero based skill number, LPARAM = lock direction [0 = up, 1 = down, 2 = locked]
  • Returns 0 on success, 1 on failure (will fail with invalid param(s) or not logged into game). NOTE: when the lock value is set Razor requests the current skill values from the server. So don't set locks in rapid succession for a long period of time or you may lag yourself out.
Get account identifier (WM_USER + 216)
  • Parameters: None currently
  • Returns 0 if no character is logged into game otherwise a identifier for the account
