im building blackjack game in java school , can't seem figure out how add first 4 cards gpanel. array of cards shuffled , strings in array match file name of images. can first card in array load not other three. awesome.
public void paintcomponent(graphics g) { //system.out.println(gameinprogress); if(gameinprogress == true) { super.paintcomponent(g); graphics2d g2 = (graphics2d) g; image image = null; int i; currentposition = 0; (i = 0; < 4; i++) { image = toolkit.getdefaulttoolkit().getimage("images/"+deck[currentposition - i]+".png"); currentposition++; } g2.drawimage(image, 115, 5, 80, (int) 106.67, this); g2.finalize(); } }
you have 3 main issues in code.
the first issue caused [currentposition - i] because result equal 0, image/card @ array index 0 1 ever drawn.
the second issue draw 1 image because g2.drawimage called after loop, instead should inside loop 4 images/cards drawn.
the third issue draw images in same place, if drawing 4 images see last 1 because covers previous ones.
try this, should print 4 images (assuming have 435x112 panel):
public void paintcomponent(graphics g) { //system.out.println(gameinprogress); if(gameinprogress == true) { super.paintcomponent(g); //add couple new variables int x = 115; graphics2d g2 = (graphics2d) g; image image = null; int i; (i = 0; < 4; i++) { image = toolkit.getdefaulttoolkit().getimage("images/"+deck[i]+".png"); //new location of g2.drawimage //the x positions should change each time g2.drawimage(image, x, 5, 80, 107, this); //change x location of next image x = x + 80; } //moved g2.drawimage here above bracket g2.finalize(); } }
