Robot class slowing down
I am using the robot class to make a macro that moves and clicks the mouse for a few hours. At first, the macro works correctly, and completes about five runs per second. However, after a few minutes the macro starts slowing down, and after an hour it is running through once every 10 seconds. Every run is exactly the same, so why could it be slowing down?
Here's exactly what it's doing:
1. get the color of the next pixel in a BufferedImage.
2. make a robot and have it type the RGB values of the pixel into another window.
3. move the mouse and click it a few times.
I'm not using the hard drive. I'm not searching anything. I am not copying anything. Every run is exactly the same. Why is it getting slower as it runs? It finishes about a quarter of the image in 5 minutes, then hours later it has only done a few more rows.

Timer Class not accurate and slows down my animation!?
Does anyknow how why my timer object is not accurate and why it slows down my animation that is also present on my GUI at the same time?
I have a timer in the form of 0.00 the left of the decimal point should represent a second but it doesnt, run my code and see for yourselves. below is my code if anyone can fix these 2 problems i will be very thankfull:

xfoI'm (being lazy and) using the older RT app posted on your last thread. I removed the
TimeNow timer from the RT class and used System.currentTimeMillis (as you requested) to
determine the elapsed time during the animation (see "startTest", "stop" and
"movingObject" methods). Also changed the DecimalFormat to NumberFormat and set the
"maximumFractionDigits" to "2" so it will truncate the fraction to two digits (more simple
than before). Made arrangements for the ShapeMovingPanel class to update the
"timerJTextField" during the animation (RT.updateTime method).
The MouseMotionListener is causing the animation to appear jerky and uneven. The
"mouseMoved" method is very busy while the mouse is moving. You might consider recording
the "mousePressed" events instead of the "mouseMoved" events, ie, the events where the user
is attempting to click inside the moving shape. It would allow the app to be more
responsive and might eliminate the uneven motion of the animating shape.

How do I get rid of the Not Using SoftArtisan File UP notice that is slowing down my uploads to class where I teach? A notice now appears every time I upload an image to class as an attachment that says, Not Using SoftArtisan File UP, and this appears to be slowing down my uploads tremendously. I want to get rid of this. I never used it before and don't need it and don't want it. I just want the uploads to work like they did before this idiotic notice started slowing things down.
Hello,

Does loading too many classes into jvm slow down performance?
hi all,
does loading too many classes into jvm will slow down performance. Our application is CPU bound, if we use any framework we need to load all the classes related to that framework in JVM. Does this have any effect on the performance of the JVM.
thanks and regards,
akmaldoes loading many classes into jvm slow down performance.It will increase the time it takes for the JVM to load your application.
Our application is CPU boundThe time it takes the JVM to load your application is not likely to be an issue for you then. -
I need to make a macro with the robot class that draws a picture in a paint program. For each color in the image (256 colors total) it should change the paint color and drawing each 2x2 pixel that's that color. I made the program and it works correctly for about an hour, but then it starts slowing down a LOT, entering the wrong color codes, and drawing single pixels instead of 2x2.
Here is the code for changing the color:
robot.mouseMove (535, 504);
robot.mousePress (InputEvent.BUTTON1_MASK);
robot.mouseRelease (InputEvent.BUTTON1_MASK);
robot.mouseMove (568, 410);
robot.mousePress (InputEvent.BUTTON1_MASK);
robot.mouseRelease (InputEvent.BUTTON1_MASK);
robot.mousePress (InputEvent.BUTTON1_MASK);
robot.mouseRelease (InputEvent.BUTTON1_MASK);
for (i = 0; i < 6; i++)
robot.keyPress (color.toUpperCase ().charAt (i));
robot.keyPress (KeyEvent.VK_ENTER);
robot.keyRelease (KeyEvent.VK_ENTER);Here is the code for drawing each pixel:
robot.mouseMove (415 + (w * 2), 185 + (h * 2) - 1);
robot.mousePress (InputEvent.BUTTON1_MASK);
robot.mouseMove (415 + (w * 2), 185 + (h * 2) + 1);
robot.delay (100);
robot.mouseRelease (InputEvent.BUTTON1_MASK);Does anyone know why the robot stops working after about an hour?I'll guess that this might have something to do with it:
for (i = 0; i < 6; i++)
robot.keyPress (color.toUpperCase ().charAt (i));
//need to release the key!
robot.keyRelease (color.toUpperCase ().charAt (i));
}Also, about your code to draw one pixel: it draws three pixels in a vertical line, at least in my paint program. -
I am creating an automotive braking system using flash and have a wheel turning. I want the wheel to slow down and stop after the brake pedal is pushed at a certain frame. I know I could do this with frame by frame animation but was hoping there was a short cut - javascript?? If not the slowing down portion then is there code for just making the internal movie clip (wheel turning) to stop when it gets to a frame.? Thanks
you can use the ticker class to create a loop that you use to control the wheel's rotation or frame, TweenJS v0.6.0 API Documentation : Ticker

High CPU usage and program slowing down
Hi. I have helped write a program in AS3 that uses classes. We have 2 frames in our movieclip that consists of an ant moving. We have a class of ants and can create 15 instances of them and the program runs fine with the ants walking around looking for food and going back to a corner that is their nest and going back out again. The ants also respond to mouse movement if the mouse pointer is near an ant.
If we create more than 15 ants, then the program starts to slow down. If we have 30 ants on the screen, then there is noticable stuttering of the ant movement. The CPU usage on a P4 2.5Ghz Pentium is around 50%.
Is this normal? or is something wrong?
I would have thought we would be able to scale up the number of ants easily.
Thanks
Trev.Hi kglad.
Thanks for the reply.
I assume enabling cacheAsBitmap is set in the ant class Constructor, as we have tried that and it has helped, see below. We can now create 30 ants with very slight stuttering.
We have an ant class as below.
public class TAnt extends MovieClip { // lots of code here }
ant Constructor as below.
public function TAnt(newX: Number, newY: Number, sW: Number, sH: Number, rCyc: Number) {
this.cacheAsBitmap = true;
// more code here }
// We have implemented a Finite State Machine for the ant behaviour.
regarding the ants using a loop and using a controller class, I am not sure what you mean.
We are creating instances of the ants in the Ants.fla file which is in the Action file and add each new ant to an array. See below.
for (var a = 0; a < nAnts; a++) {
var newAntX = Math.random() * screenWidth; // randomly generate ant location
var newAntY = Math.random() * screenHeight;
var rCyc = Math.random() * 800;
var ant = new TAnt(newAntX, newAntY, screenWidth, screenHeight, rCyc); // create ant
addChild(ant); // add ant so visible on screen
ants.push(ant); // add ant to array
So we use an array for looping through the ants in the Ants.fla Action file.
Is this the way you mean?
Thanks

Windows 7 Pro on iMac (mid 2011) and network slows down
We have an office with about 8 mid 2011 21" iMacs running Windows 7 Pro courtesy of Bootcamp. The machines boot quickly and all programs open quickly. They each have from 2 - 4 mapped network drives to a 2012 Windows Server 2008 R2 HP GL380 server on-site and are wired with Gig Ethernet HP business class switches). The users' Documents, Desktop, and a couple other directories are re-directed to the file server using an Active Directory Group Policy Object (GPO).
A couple of the computers will regularly start to slow down after only 20 or 30 minutes of use. The rest have occasionally experienced it but it's always independent of others experiencing the slowdown. The computers with the more regular slowdowns I've also booted into OS 10.7.x and the transfer rates to the same file server are fast and consistent. BTW, all computers are current on Windows updates and Apple updates.
I've tried some of the suggestions I found here: http://www.neowin.net/forum/topic/950538-running-windows-7-via-bootcamp-on-mac-m ini-slows-down-over-time/
1.)
Disable all property's that has something to do with "Offload" under advanced on the nic properties.
Also disable "Recieve Side Scaling".
And set "Speed and Duplex" to auto.
2.)
Turn off windows feature "Remote Differential Compression" (Uninstall) under "programs and features".
3.)
Run fallowing command in cmd:
netsh int tcp set global autotuninglevel=disabled
netsh int tcp set global chimney=disabled
i ran disabled on every setting i could.
so it looks like this now:
C:\Users\tab>netsh int tcp show global

Hi
I am trying to make a little robot that can draw a 2D map of the suroundings. (It uses a rotating distance sensor, like af radar)
I whant to use the picture-control, to draw in the information, so i can get a printable picture out. I have already created a "picture-radarbeam" that reprecents one meassurement in the picture, and it works just fine.
So, the problem is then i try to put the picture in a while-loop and i want the program to sketch the measurements all the time (I mean updating the picture canstantly). Short after it starts, its slows down dramaticly (It seams like it reamember all the preavues sketches, and sketch them all every time the picture updates.). I tried to solve the problem by write the pictue to a image-file, and then load it again to a picture-string, but that is also a very slow solution.
Any sugestions?

hi have anyone an idea how can i make screenshoot from my scene without the class robot?
at moment i use the Robot class to make screenshoots from my sceene
Rectangle screenRect = new Rectangle(20,10,800,600);
try{
Robot robot = new Robot();
BufferedImage image = robot.createScreenCapture(screenRect);
ImageIO.write(image, "png", new File(fileName));
} catch (AWTException e1) {}
catch (IOException e) {} thats the code to make screenshoots but i think its not good to use AWTThat depends: when modularity kicks in (Java 9 with early availability in Java 8?) you may end up with some light JVMs tailored for JavaFX-only without any AWT / Swing support. And if you are not connected to the Net (which is more common than you may think) you may not be able or want* to download the extra module(s) that give AWT / Swing support.

WOW jeje i just notice your code looks like a game
since i'm not an expert in games dont take this as an advice this is only a question: why would you need to slow down the x=x-speed? cant you use a smaller value for speed?
all the events run inside a single Thread called ThreadDispatcher so if you are calling events a lot then your calling fire() a lot and if the fire() method is
a long task the other events have to wait until the fire method finished to get their time.

(B.T.W -- An instance of LayerManager controls drawing the level)
The application draws the whole tiledlayer (onto the offscreen buffer) but only shows whats appropriate to the view window.
The application calculates which bit of the tiledlayer needs to be drawn to the view window, but as the tiled layer gets larger, the calculations become alot more complex (therefore slowing the app down)
I cant really think of any other way of drawing a large background without slowing down the application. If i use sprites I will end up with 400 of them (One for each tile), and that would slow the application down to miniscule rates( especially when I try to calculate collision detection for about 80 tiles)
This is the code use for constructing a simple level:
*MAIN GAME CLASS
public class Level extends TiledLayer
*Dimension Fields - Constant after intitialisation
/*The width of the square tiles that make up this layer*/
static int TILE_WIDTH = 34;
/*The Height of the square tiles that make up this layer*/
static int TILE_HEIGHT = 34;
/*This gives the number of squares of "texture" to put along
the screen -- Changing this to 10 means a smaller level but faster game*/
static int INITIAL_COLUMNS = 23;
/*This gives the number of squares of "texture" to put along
the screen -- Changing this to 10 means a smaller level but faster game*/
static int INITIAL_HEIGHT = 23;
public Level() throws Exception
super(INITIAL_COLUMNS, INITIAL_HEIGHT, Image.createImage("/icons/Level.png"), TILE_WIDTH, TILE_HEIGHT);
/*Quickly fill some cells*/
fillCells(1, 1, 20, 1, 1);
fillCells(1, 1, 1, 20, 1);
/*sets object position*/
setPosition (0, 0);
void reset()
setPosition (0, 0);
}I didn't see it in your code but I am sure you are using a for(x;x;x) loop to draw the scene.
Yes, your are correct, your slow down is that all of your map is being processed as if it were all going to be drawn to the screen. You have to write the code that avoids this. On your 10x10 you are running the loops 100 times, but when you increase the size to 23 by 23 you are running the loops 529 times every time you have to redraw the scene. The solution is to set up some tracking variables and put them in your loop so we only have to run the loops 81 times, no matter how big the map is.
Something I have been trying lately is drawing all of my layers in one for loop.
map_width = 32; // this is the size of the map
map_height = 32; // not all of the map will fit in the screen
width = 9; // this is the tile size of the screen
height = 9; // 9 tiles wide, 9 tiles high
character_x_possition = (possition x on the map divided by 34 which is your tile width);
character_y_possition = (possition y on the map divided by 34 which is your tile width);
corner_x = character_x_possition - 4; // or 5?, just try it, I can't remember
corner_y = character_y_possition - 4; //or 5 again
for(int x = corner_x; int < corner_x + width; x++)
{ for(int y = corner_y; int < corner_y + height; y++)
Draw layer 1 to backbuffer
if(x == char_possition && y == char_possition)
{ Draw Character to back buffer }
else { Draw layer2 to back buffer}
Draw layer 3 to back buffer
Draw back buffer to screen
//////////// END OF SORT OF CODE :-) /////////////
You can also use something similar to cut out time in colision checking, theres no since in checking the entire scene for colision when there are only 9 possible colisions at a given time, there are also some advanced meathods such as quad trees, but these at the moment are beyond me until I can find the time to sit down and study them. Hopefully some else will post on these, but they be beyond the needs of your game. I breifly read over them and went with the 9 tile checking for my game.
One other note, if this is an rpg, there is rarely benefit for an offscreen NPC to be moving. :-) -

"No pool in place - just leaking" Error slowing down MacPro
Whenever I am running the creative cloud app. I am getting this error message in my console:
Creative Cloud[4627]: objc[4627]: Object 0x792c53f0 of class __NSCFData autoreleased with no pool in place - just leaking - break on objc_autoreleaseNoPool() to debug
It comes up every half a second, and is slowing down my computer...
please help! I was on the phone with tech support for over an hour, and no help at all.
Thanks,
LeahHI,

I have the same messages in Console also. I don't think it's anything to be concerned about. It's just programming language.

Doing Shift-End using Robot class
I am trying to use the Robot class to do a Shift-End in order to select the text in a window from the cursor to the end of the line. However, the following code only moves the cursor to the end of the line without selecting the text.
robot.keyPress(KeyEvent.VK_SHIFT);
robot.keyPress(KeyEvent.VK_END);
robot.keyRelease(KeyEvent.VK_END);
robot.keyRelease(KeyEvent.VK_SHIFT);
Note that I have been able to make the following code work. So the problem with the code above does not seem to be with the Shift key per se or with the ordering of the statements.
robot.keyPress(KeyEvent.VK_SHIFT);
robot.keyPress(KeyEvent.VK_A);
robot.keyRelease(KeyEvent.VK_A);
robot.keyRelease(KeyEvent.VK_SHIFT);
Any idea how to make the Shift-End work? I am using an XP PC.My ENTIRE code follows. Not surprisingly, the shiftEnd.actionPerformed gets a nullPointerException during execution. And being new to Java, I get the feeling I might be missing a whole bunch of stuff. For example, do I need to register for events? Do I need to generate a shift-End ActionEvent somehow? It is only the last 4 lines that are at issue here. Everything down to that point accomplishes what I want, i.e., position the mouse in a text window in the upper right-hand corner of my screen, move the cursor to the top of that window, then go down 5 lines. At that point, I want to do the shift-End to select all text in the line.
import java.awt.*;
import java.awt.event.*;
import javax.swing.KeyStroke;
import javax.swing.JTextField;
public class KeyStrokeTest {
/** Creates a new instance of KeyStrokeTest */
public KeyStrokeTest() {
* @param args the command line arguments
public static void main(String[] args)
throws AWTException{
Robot robot = new Robot();
// Position mouse over Test Director test
robot.mouseMove(600,300);
// Press and release left mouse button to set focus in Test Director test
robot.mousePress(InputEvent.BUTTON1_MASK);
robot.mouseRelease(InputEvent.BUTTON1_MASK);
// Go to top of Test Director test
robot.keyPress(KeyEvent.VK_CONTROL);
robot.keyPress(KeyEvent.VK_HOME);
robot.keyRelease(KeyEvent.VK_CONTROL);
robot.keyRelease(KeyEvent.VK_HOME);
// Go down to first line of request
for(int i=0;i<5;i++) {
robot.keyPress(KeyEvent.VK_DOWN);
robot.keyRelease(KeyEvent.VK_DOWN);
robot.delay(1000);
// Do a shift End
KeyStroke keyStroke = KeyStroke.getKeyStroke(KeyEvent.VK_END,KeyEvent.VK_SHIFT);
JTextField textComponent = new JTextField("String");
ActionListener shiftEnd = textComponent.getActionForKeyStroke( keyStroke );
shiftEnd.actionPerformed( null );
