UO.GetTradeOpponent
ClassicUO • Runtime API
Returns the trading character’s numeric serial.
Exact syntax
UO.GetTradeOpponent(TradeNum:Any) -> Any
Parameters
TradeNum— Integer current window number, 1 through TradeCount(). Zero and negative numbers are invalid. Not a serial.
Returns
Integer: partner character serial from the window’s LocalSerial; 0 if absent. Not a container or Boolean; test <> 0.
Behavior
- GetTradeContainer/GetTradeOpponent/GetTradeOpponentName/ConfirmTrade/CancelTrade number windows from 1; TradeContainer/TradeOpponent/TradeName and every TradeCheck form index them from 0. This client deliberately preserves those conventions; reference manuals from different engines disagree on origins.
- Reads run on the game thread using live windows in this World. Disposed windows are excluded. Reading sends no packets and waits for no response. UI ordering may change when windows open, close or move to the front; an index is not a persistent identifier.
- ConfirmTrade and writing your TradeCheck box send a packet only when acceptance changes. The server controls the other box. CancelTrade sends cancellation once. 1/TRUE means local state/handling, not completed transfer. Names and both checks do not prove that offered items stayed unchanged.
Internal functions: from call to result
The C# call path is explained below, followed by executable Basic helpers. The scripts do not reimplement the network protocol.
1. ExecuteStealthCompatibility
Registration selects by argument count and NumberConversions converts numbers. The two-argument TradeCheck validates sides 1/2 and maps them to bridge indices 0/1. Legacy serials pass through ToHex.
Integer: partner character serial from the window’s LocalSerial; 0 if absent. Not a container or Boolean; test <> 0.
Project source: external/InjectionScript/src/InjectionScript/Runtime/InjectionApiUO.cs; function ExecuteStealthCompatibility.
2. GetTradeOpponent
Invoke marshals reading/writing to the game thread with script cancellation; the method reads ID1/ID2, LocalSerial, OpponentName or acceptance flags from the selected TradingGump.
Returns the trading character’s numeric serial.
Project source: src/ClassicUO.Client/Game/Managers/ClassicUOInjectionApiBridge.cs; function GetTradeOpponent.
3. FindNumberedTrade
FindNumberedTrade validates number>0 before subtracting 1; FindTrade rejects negative indices and enumerates only live TradingGump windows belonging to this World.
GetTradeContainer/GetTradeOpponent/GetTradeOpponentName/ConfirmTrade/CancelTrade number windows from 1; TradeContainer/TradeOpponent/TradeName and every TradeCheck form index them from 0. This client deliberately preserves those conventions; reference manuals from different engines disagree on origins.
Project source: src/ClassicUO.Client/Game/Managers/ClassicUOInjectionApiBridge.cs; function FindNumberedTrade.
The helper is fully defined and called by Main. Range/ID checks reduce mistakes but calls are not atomic: the selected window may change between them. For an action, expectedPartner is a saved character serial, not a price or contents validation.
Examples
Direct read or action
# Direct read or action
#
# Returns the trading character’s numeric serial.
#
# Integer: partner character serial from the window’s LocalSerial; 0 if absent. Not a container
# or Boolean; test <> 0.
SUB Main()
# Call once and save value/result. Zero is the first index, one the first number (see this
# command’s syntax). HEX displays numeric serials; CStr displays numbers or text.
VAR value = UO.GetTradeOpponent(1)
UO.Print(HEX(value))
END SUB
Parameter and execution notes:
- Call once and save value/result. Zero is the first index, one the first number (see this command’s syntax). HEX displays numeric serials; CStr displays numbers or text.
