Win32 boucle de jeu

Je crée un jeu simple en utilisant l'API Win32. Quand je clique sur la fenêtre, une boule apparaît et commence à rouler ressembler à un jeu de bidaWin32 boucle de jeu

Mon problème est quand j'appelle "InvalidateRect", mon jeu très lag. Je ne sais pas que je fais quelque chose de mal !!!

Et mon HPEN ne fonctionne pas comme ce que j'attends

S'il vous plaît aider !!! Merci et désolé pour mon mauvais anglais

Essayez un débogage. Vous ne vérifiez pas les valeurs de retour. Peut-être que certains de ces appels échouent. Où le programme passe-t-il son temps? Et l'utilisation d'asm rend votre vie très difficile pour absolument aucun avantage du tout. –

Ce n'est pas une bonne idée d'utiliser le temps du système pour des problèmes de vitesse. Utilisez votre procédure moveEllipse à la place et augmentez vectorX et vectorY pour plus de vitesse. InvalidateRec devrait être appelé s'il y a une vraie mise à jour nécessaire. Vous pouvez atteindre cela en utilisant une minuterie au lieu de changer et de vérifier l'heure du système: SetTimer.

Un débordement de pile est en train de se produire, vous avez probablement l'intention d'appeler "PeekMessage" à la place de "GetMessage" L'ID de temporisateur est également choisi de manière inappropriée. Il est de type "UINT_PTR". peut passer une adresse mémoire unique – IInspectable

@IInspectable: Je voulais dire 'GetMessage' et enlevé le mauvais push Désolé 'UINT_PTR' signifie [*" Un entier non signé, dont la longueur dépend de la taille du mot du processeur "*] (https://msdn.microsoft.com/library/cc248915.aspx) Il n'a pas besoin d'être unique et doit être une valeur directe, pas une adresse mémoire – rkhb

Il doit être unique pour une minuterie. s d'une entité distincte est le moyen le plus simple de garantir l'unicité. C'est pourquoi l'ID est un "UINT_PTR" (par rapport à un "UINT", ce qui serait ** suffisant ** pour contenir un identifiant unique pour les minuteurs simultanés pris en charge maximum). Voir [Comment appeler SetTimer avec un ID de temporisateur qui est garanti pour ne pas entrer en conflit avec un autre ID de temporisateur?] (Https://blogs.msdn.microsoft.com/oldnewthing/20150924-00/?p=91521). – IInspectable

Vous gérez un seul message entre l'exécution de votre GAME_LOOP. Cela ne présage rien de bon. Au lieu de cela, vidangez toute la file d'attente de messages entre les mises à jour d'écran. La solution est simple: Ajouter

jmp MESSAGE_LOOP

juste après

call DispatchMessage

Merci, mais il est encore en retard :( –

@ hinhVănKiệt: Eh bien, un appel à 'SetSystemTime' pour implémenter la synchronisation locale, process-private, n'est pas idéal non plus.Il y a probablement beaucoup plus de problèmes avec le code, mais ma réponse – IInspectable
