[1.7.10] Comment centrer un gui ?

JustAnDev

Regarde sur une gui de la meme type que toi(exemple:Si ta classe est extend de Gui Screen regarde dans le code du jeu une classe qui est extend de guiscreen (ils sont tous centrés))

kraniax

Ok merci, tu m’expliquer à quoi correspond width et height. Je sais que c’est la longueur mais je sais pas de quoi.

JustAnDev

Je peux voir le code de la classe que tu regarde car je pense que c’est la taille de l’image mais j’en suis pas sur

JustAnDev

ok donc le seul truc que je vois a rapport avec ton precedent message que le guiWidth et guiHeight et ca c’est bien la taille de l’image

kraniax

Non, la taille de mon image est de 256x256 mais lorsque je met une valeur plus basse mon image s’affiche quand même.
J’ai été voir dans le code du hopper, la valeur height est pas la même que la taille de l’image qui est de 256.

JustAnDev

Je parle de la taille de l’image par Minecraft!(pas de ton vrai image)

kraniax

J’ai pas compris la taille de l’image par Minecraft.

JustAnDev

La taille reperé par Minecraft(genre si je met x = 20 et y = 20 il va couper mais toi c’est pas le cas(J’ai vu le truc de la transparence: ) ))(Attends on parle de centrage pas de taille?)

kraniax

Ah ok, oui je parle de centrer l’image mais pour la centrer il faut qu’il y est le bon guiWidth et guiHeight et ensuite faire :

int guiX = (width - guiWidth) / 2
int guiY = (height - guiHeight) / 2

JustAnDev

J’ai fait un calcul
(ecran de 256 px avec gui de 256px et le result est 0(debut de la pos mais je vais test pour un screen de 1280*720 donc ul demmare dans le width a 512 et height a 232 apres j’ai pas verif si c’est le milieu mais bof bof on fait avec))

kraniax

Le result, c’est quoi ?

JustAnDev

512 et 232

kraniax

Oui, mais ça signifie quoi le result, c’est la valeur de “width” et “height” ?

JustAnDev

ouais c’est la pos que t’auras sur un screen 1280*720

kraniax

C’est-à-dire que si je marque :

drawTexturedModalRect(width, height, 0, 0, guiWidth, guiHeight);

Le gui va apparaître aux coordonnées 512 et 232 ?

JustAnDev

nan c’est bien le code mais aux zéros ajoute guiX et guiY(et suppr les zéros car tu vas le placer au tout debut (et ce que j’ai dit c’est si mc a une réso(taille) de 1280*720)

kraniax

Ah ok, merci. Est-que par contre tu sais pourquoi lorsque j’ouvre mon gui des fois ça crash et des fois non ?

JustAnDev

Sans rapport je ne peux t’aider

// Don't be sad. I'll do better next time, I promise!
