Alô turma do Guj!
Tô tentando fazer uma brincadeira aqui, usando a classe runnable e thread. Conheço um pouco de java, mas essas classes estou começando a usar. O problema que apareceu é: Eu executo a classe ‘Pinball’ clico no button ‘start’ e a label azul(que depois vai ser a bola) se move no eixo y ate um ponto aleatorio e outro método faz ela ir à esquerda e então a idéia é rebater com uma label ‘Raq’ . Tá tudo no começo. o problema é que enquanto a label azul está se movendo prá esquerda e mesmo depois que ela pára a label amarela ‘raq’ trava e não consigo movê-la com as setas ‘->’ e as demais. Só consigo fazer funcionar as setas reiniciando a aplicação ou antes de clicar em ‘start’. Porque esse travamento enquanto as classes que movem o quadrado azul(‘bola’) estão em execução? Onde está o êrro? Me ajudem, por favor! Abaixo estão as classes envolvidas no programa.
