java - why is it only painting one of the components? -
package puzzle; import java.awt.color; import javax.swing.*; import java.util.*; public class puzzle { integer x = 50; integer y = 50; int x2 = 100; int y2 = 100; int vnotx = 0; int vnoty = 0; float t = 0; float t2 = 0; jframe frame = new jframe(); move m = new move(x, y,color.green); move n = new move(x,y,color.orange); java.util.timer timer = new java.util.timer(); java.util.timer timer2 = new java.util.timer(); public puzzle() { frame.setundecorated(true); frame.setsize(400, 400); frame.add(m); frame.add(n); frame.addkeylistener(new java.awt.event.keyadapter() { public void keypressed(java.awt.event.keyevent evt) { formkeypressed(evt); } }); com.sun.awt.awtutilities.setwindowopacity(frame, 1f); timer.scheduleatfixedrate(new timertask() { public void run() { rd(); } }, 0, 20); timer2.scheduleatfixedrate(new timertask() { public void run() { t2+=.01; x2 =(int) ((math.cos(t2)+1)*100); y2 =(int) ((math.sin(t2)+1)*100); system.out.println(x2+", "+y2); } }, 0, 2); } int z = 0; public void rd() { z++; m = new move(x, y, color.green); n = new move(x2, y2, color.orange); frame.add(n); frame.add(m); frame.validate(); } private void formkeypressed(java.awt.event.keyevent evt) { int id = evt.getid(); int kc = evt.getkeycode(); if (kc == 39) { final java.util.timer right = new java.util.timer(); right.scheduleatfixedrate(new timertask() { public void run() { t += .01; int x1 = x; if (x + 51 < 400) { x = x1 + (int) (10 * t) + (-1 * ((int) (20 * t * t))); } if (t > .5) { t = 0; right.cancel(); } } }, 0, 10); } if (kc == 37) { final java.util.timer left = new java.util.timer(); left.scheduleatfixedrate(new timertask() { public void run() { t += .01; int x1 = x; if (x - 1 >= 0) { x = x1 + (int) (-10 * t) - (-1 * ((int) (20 * t * t))); } if (t > .5) { t = 0; left.cancel(); } } }, 0, 10); } if (kc == 40) { final java.util.timer right = new java.util.timer(); right.scheduleatfixedrate(new timertask() { public void run() { t += .01; int y1 = y; if (y + 51 < 400) { y = y1 + (int) (10 * t) + (-1 * ((int) (20 * t * t))); } if (t > .5) { t = 0; right.cancel(); } } }, 0, 10); } if (kc == 38) { final java.util.timer left = new java.util.timer(); left.scheduleatfixedrate(new timertask() { public void run() { t += .01; int y1 = y; if (y-1 >= 0) { y = y1 + (int) (-10 * t) - (-1 * ((int) (20 * t * t))); } if (t > .5) { t = 0; left.cancel(); } } }, 0, 10); } if (kc == 32) { } if (kc == 67) { } if (kc == 77) { } } public static void main(string[] args) { new puzzle().frame.setvisible(true); } } why not adding both instances of move class. adds last 1 called. class paint below should change in order paint both instances of move
package puzzle; import java.awt.*; import java.awt.geom.*; import javax.swing.*; public class move extends jpanel{ int x; int y; color kk; public move(int x1, int y1, color k) { x=x1; y=y1; kk = k; } public void paintcomponent(graphics g) {graphics2d g2 = (graphics2d)g; super.paintcomponent(g2); g2.setcolor(kk); g2.fill(new roundrectangle2d.float(x, y, 50, 50,10,10)); g2.drawstring(x+", "+y, 200, 200); } } the class move paints rectangle position , color passed puzzle class
are taking layout managers consideration? know jframe's contentpane using borderlayout default layout manager, , if add components without constants, added borderlayout.center, , 1 of these can visible @ time (the last added).
i think might better disassociating move jpanel, yes making paintable, making more of logical object rather gui component , instead of having extend jpanel, allow single drawing jpanel hold 1 or more move objects , draw move objects in jpanel's paintcomponent method.
also, seem using several java.util.timers in code, since swing application, better served using javax.swing.timers instead, in fact perhaps 1 swing timer functioned game loop.
