Queries

Queries request information about the state of the world from Osiris. They can be used in the part of a rule that checks conditions. Queries almost always succeed, except if you pass an initialised value as an [out] parameter and it does not match the value the query would returns. Below, this will be called the Default Return Value. If a query can also fail under other circumstances, this will be mentioned.

    CharacterIsAlly

    Full definitions

              GetClosestAlivePlayer

              Full definitions

                Notes

                • Be careful if you check for extra conditions on the returned player: if any of those conditions fail, no other players will be considered.
                • If you want to start a dialog, use ProcGetClosestAvailableCharacterTo

                Notes

                • This call returns the outermost container. I.e., if a character has crate in their inventory, and the crate contains a pouch with the item, this call will return the character.

                Notes

                • This routine will first get a random position in the trigger, and if this random position is not valid on the AI-grid, the coordinates will be snapped to a nearby valid position on the AI-grid.
                • This call does not work for polytriggers

                Return values

                • <b>Success/Failure: </b>Default return value.
                • _Bool: 0 if _Status has not been applied to _Target, 1 if it has been.
