Finde die Fehlerquelle nicht

Recommended Posts

Guten Abend

Ich bin auf einen Error zugestoßen, den ich nicht beheben kann bzw. da mir das Wissen dazu fehlt. Diesen Error lässt mich nicht in den Gamemode rein...

Kann mir jemand verraten, wie man diesen Fehler beheben kann? Wäre sehr dankbar auf eine hilfreiche Antwort :D

Der Fehler versteckt sich anscheinend in Zeile 110:             Vector3 targetVelocity = new Vector2(move * 10f, m_Rigidbody2D.velocity.y);

Gruß

Die Fehlermeldung sagt doch ziemlich genau was los ist.

Du willst auf eine Rigidbody2D-Komponente zugreifen, aber das GameObjekt "offiziell fertiger Charakter 3" hat diese Komponente nicht.

Würde also mal drauf tippen dass du das noch hinzufügen musst?

Achso, ggf mal

m_Rigidbody2D = GetComponent<Rigidbody2D>();

zu

m_Rigidbody2D = gameObject.GetComponent<Rigidbody2D>();

ändern, falls die Komponente vorhanden ist?

vor einer Stunde schrieb Damian izz back:

Wie bereits erwähnt liegt der Fehler anscheinend bei Zeile 110

Nur weil der Fehler in einer Zeile auftritt, heißt es nicht, dass der Fehler in dieser Zeile liegt.

Wenn du eine Komponente nicht auf deinem GameObject hast, dann gibt GetComponent eben null zurück beim Versuch, die Referenz zu besorgen. Knallen tut's aber erst, wenn du die nicht existente Komponente benutzt, und das passiert eben in Zeile 110. Du hast definitiv keine Rigidbody2D-Komponente auf einem GameObject, auf dem dieses Script liegt.

Sag mal, wie häufig willst du eigentlich noch ein Thema mit dem Titel "Finde die Fehlerquelle nicht" erstellen? Versuch doch im Titel dein Problem zu benennen. Das macht es uns als Forenmitglieder einfacher zu Wissen, ob wir eventuell helfen können.
