Problem med kryds og bolle spil
Hey Jeg sidder og roder med et lille kryds og bolle spil. Men jeg har et problem som er ved at give mig grå hår :S Når man klikker på et felt for henholdsvis at placere et kryds eller en bolle, så ska man klikke to gange før den første "brik" bliver sat. Efterfølgende virker det fint. Her er min paint metode: if(gameState == GAME_STATE_INTRO) { g.drawString("Kryds og bolle :)", 100, 100); } else if(gameState == GAME_STATE_START) { // tegn bræt m.m. board.draw(g,Color.red, tur); writeMessage(g); board.drawPieces(g); } Her er den metode som skal tegne brikkerne: public void drawPieces(Graphics g) { int _x = this.width / 3; int _y = this.height / 3; int i = 0; Piece piece = new Piece(); while(i < pieces.size()) { piece = (Piece) pieces.elementAt(i); g.drawImage(piece.pic, this.offset + _x*piece.x + 2, this.offset + _y*piece.y +2, null); i++; } } og koden til at placere en brik: int i = -1; if(board.convertPos(mouse).x != -1 && board.convertPos(mouse).y != -1) { i = board.setPiece(tur, board.convertPos(mouse).x, board.convertPos(mouse).y); if(i == 0) tur(); else if(i == 2) setMessage(1, "Feltet er allerede fyldt!", Color.red); } else { setMessage(1, "Ugyldigt felt!", Color.red); } og setPiece() : public int setPiece(int tur, int cellx, int celly) { Piece piece; if(cells[cellx][celly] == NOT_ASSIGNED) { cells[cellx][celly] = tur; if(tur == 0) piece = new Piece(circle); else piece = new Piece(square); piece.assign(cellx, celly); pieces.add(piece); return 0; } else return CELL_ALREADY_USED; } håber i ka finde problemet :)
