Funktion aus Unit1 in Unit3 benutzen

[Pseudemys Nelsoni]

Moin,

ich habe die unit1 in der die funktion ist in meiner unit3 eingebunden, wenn ich die funktion in der unit 3 verwenden möchte bekomme ich aber trotzdem

Zitat:

[Fehler] Unit3.pas(97): Undefinierter Bezeichner: 'GetLevel'
[Fataler Fehler] Unit1.pas(74): Verwendete Unit 'Unit3.pas' kann nicht compiliert werden

weiss jemond warum?

[mirage228]

in die unit3 schreiben:

Delphi-Quellcode:

uses
  { ... }, Unit1;

voila, fertig

unit1 ist in unit3 und unit3 in unit1, deswegen weiss ich nicht wieso das nicht geht :\

unit1 sieht so aus:

uses Unit3, Unit2;


unit3 sieht so aus:

uses Unit1;

[Wormid]

Steht die Funktionsdeklaration von GetLevel im Interface-Teil der Unit1?

[Pseudemys Nelsoni]

jo, bei den ganzen anderen proceduren die automatisch hinzugefügt werden...also ganz oben unter "type"

ist das falsch?

[andianon]

Stehen die "uses unit1" bzw. "uses unit3" jeweils im interface-Teil? Kreuzreferenz?

[Thunderchild]

Die automatisch erzeugten Prozeduren dürfen nicht in Private stehen. Wenn dem so ist, verschiebe sie nach public.

[Pseudemys Nelsoni]

ich weiss nicht ganz wie das gemeint ist, aber ich habe 2 uses (wie immer) in meinen units, und die units die ich eingebunden habe sind beim 2ten "uses"(warum gibts den teil überhaupt 2mal?)

[andianon]

Warum zweimal ist an anderer Stelle nachzulesen. Kannst du die beiden Units posten?

[Pseudemys Nelsoni]

klar, wird zwar bisschen viel aber ....


also das ist unit1 derzeit:
