Guten Abend @all!
Ich bin nun schon mehr als 3 Stunden dabei dieses PathFinding-Script von "Near Fantastica" zum laufen zu bekommen. Das mit dem Player-Pathfinding klappt wunderbar, aber wenn ich die Funktion Event-Pathfinding probiere (wozu ich es auch brauche) bekomme ich ständig "Syntax-Error" oder "Wrong Numbers of Arguments".
Habe bereits alle mir erdenklichen Schreibarten probiert, aber ich bekomms nicht hin. Hat es vllt. jemand von Euch schon mal verwendet und könnte helfen?
Ansonsten würd ich auch auf nen anderes Pathfinding-Script umsteigen, nur ich finde kein anderes. Gibt es noch mehr?
Hier ist der Quellcode:

Wenn Ihr helfen könntet wärs echt toll!:)
Ich bin nun schon mehr als 3 Stunden dabei dieses PathFinding-Script von "Near Fantastica" zum laufen zu bekommen. Das mit dem Player-Pathfinding klappt wunderbar, aber wenn ich die Funktion Event-Pathfinding probiere (wozu ich es auch brauche) bekomme ich ständig "Syntax-Error" oder "Wrong Numbers of Arguments".
Habe bereits alle mir erdenklichen Schreibarten probiert, aber ich bekomms nicht hin. Hat es vllt. jemand von Euch schon mal verwendet und könnte helfen?
Ansonsten würd ich auch auf nen anderes Pathfinding-Script umsteigen, nur ich finde kein anderes. Gibt es noch mehr?
