Apa itu thread? Nanti saya akan jelaskan di postingan yang akan datang.
Konsepnya sebenarnya sederhana, jadi ada sebuah thread yang mengatur jalannya animasi. Kita dapat mengatur millisecond ketika thread berjalan.
Inti dari project saya ini yaitu ada dua buat gambar/posisi orang, kemudian bergerak dan berubah posisi secara bergantian.
Oke langsung lihat saja source codenya, bebas untuk di utak-atik :
Buat kelas java dengan nama human2D.java

ngak jalan gan slahnya di
Balas//memanggil kelas thread
animasiOrang orang = new animasiOrang(this, xHuman, yHuman, vHuman);
animasiAwan awan = new animasiAwan(this, mulai);
oh maaf gan source codenya ada yg kelupaan. Sekarang udah di update, cek postingan gan ... ^^
BalasWah ada Willy wkwkkwkw :D
Balasijin copas gan
BalasKa ga bisa,
BalasCannot find symbol
DrawHuman(g2, xHuman, yHuman, vHuman);
bisa.. pake lowercase
BalasdrawHuman(g2, xHuman, yHuman, vHuman);
udah ka tapi masih ga bisa keterangannya cannot find symbol - method drawHuman(java.awtGraphics2D,int,int,int)
Balasitu kenapa ya ?
Kak maaf, program nya ga bisa di bagian JApplet applet = new applet();
Balasapplet.init();
frame.getcontenPane().add(applet);
Sama bagian
getContentPane().add(panel)
