Problème avec les stairs

[Deans]

Bonjour,

Oui encore moi, mais voilà j’ai voulu ajouté une stairs à mon mod sauf que quand je lance mon jeu je reçoit un crash-report alors j’ai essayé de comprendre d’où ça vient et apparemment ça vient de l’enregistrement du block enfin je croit.

Voici les codes :

Voilà j’espère pouvoir régler ce soucis. Merci d’avance.

Bonsoir,
Le NPE vient d’ici

  for(Block b : blocks)

Ta liste de bloc n’est jamais initialisé, donc forcement ça fait un NPE. Le problème est global à tous tes blocs et ne semble pas lié à ton escalier.

@Deans a dit dans Problème avec les stairs :

Block b : blocks

Bonsoir,

Merci de m’avoir répondu sauf que comment je fait pour pouvoir faire fonctionner tout ça ?

Merci d’avance.

[robin4002]

Ah, erreur de ma part, ta variable est en fait initialisé plus bas, je n’avais pas vu (dans la fonction init, ligne 56).

Mais il serait mieux de remplacer:

	private List<Block> blocks;

	public void init()
	{
		blocks = Lists.newArrayList();

Par :

	private final List<Block> blocks  = Lists.newArrayList();

	public void init()
	{

Comme ça pas de risque de npe (d’ailleurs pareil pour les blocs, vaut mieux tout déclarer en constante).

[Deans]

Je vient juste faire ce que tu m’as dit et je crash toujours et pareil que le crash-report que j’ai mis plus haut.

Il y a quoi à cette ligne ? (les lignes sur le code que tu as envoyé ne semble pas correspondre).
