PERTEMUAN 5 5.1.Teks Terdapat 2 cara memunculkan teks a. Dibuat sebagai image .png Teks dibuat dengan Photoshop / coreldraw/ atau software lain, disimpan sebagai image. Image dicopy kefolder image dari project yang dibuat. Langkah selanjutanya buat actor, actor diberi image sesuai gambar berisi teks..
b. Menggunakan class: greenfoot.image 1.membuat Actor contoh :tulisan, tanpa gambar. Buka editor, isikan program ini. import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo) import java.awt.Font; import java.awt.Color; /** * Write a description of class tulisan here. * * @author (your name) * @version (a version number or a date) */ public class tulisan extends Actor { private String huruf; private int panjangHuruf; public tulisan( String depan ) { huruf = depan; // membuat kotak untuk tulisan panjangHuruf = (huruf.length() +2) *16; setImage (new GreenfootImage(panjangHuruf,24)); // menentukan font GreenfootImage gambar = getImage(); Font jenisHuruf = gambar.getFont(); gambar.setFont(jenisHuruf.deriveFont(24.0F)); //mencetak gambar.clear(); gambar.setColor(Color.RED); gambar.drawString(huruf, 1, 18); }
2.Memanggil Contruktors, sebgai latihan di panggil dari world :
4. Supaya muncul maka perlu di tambahkan objek import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo) /** * Write a description of class Bg here. * * @author (your name) * @version (a version number or a date) */ public class Bg extends World { tulisan T=new tulisan("anak kelas C dan D"); /** * Constructor for objects of class Bg. * */ public Bg() { // Create a new world with 600x400 cells with a cell size of 1x1 pixels. super(600, 400, 1); addObject(T,200,100); } public void act(){ }
6.2 Membuat game Dasar
Siapakan bahan : 1.gambar selamat datang 2.Gambar menang 3.Gambar kalah 4.Buat project 5.Buat latar 6.Buat actor : a.musuh b.Menang( untuk menanpilkan kata menang) c.lakon d.Score e.Awal ( untuk menanpilkan kata selamat datang) f.kalah
a.Latar import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo) /** * Write a description of class latar here. * * @author (your name) * @version (a version number or a date) */
