Java hra - draggovanie obrázku (nejde) – Java – Fórum – Programujte.com

Zdravím... som v podstate začiatočník a v škole máme projekt, takú menšiu hru (zadanie vyzerá takto http://edi.fmph.uniba.sk/~tomcsanyiova/Java/11hra3x3/index.htm) a mám problém s pohybom objektu v applete... kód vyzerá takto:

(ide o môj prvý príspevok tu vo fóre, takže ak som niečo urobil zle, berte na to pls ohľad a upozornite ma, aby som vedel do budúcna)

Díky moc

Při každém paint vytváříš nové Pricitadlo. Zbytek jsem moc nestudoval.

Jop, díks. Už som vytváranie pričítadla hodil do inicializácie a je to ok. Ešte raz díky
