Why do you want your sketch to keep looping?

If the image is not big, it should be ok to let draw execute its draw normally.

You could use noLoop() and this will ensure draw is run only once. If you answer my first question or provide some code, we will be able to understand your question better.

Also, please post in the new forum: https://discourse.processing.org

Hard to say

Look at function inputs

connect the main ifs with else if so only one of them can be executed at a time

Also at the end of the function say key=0;

Note that there is a new forum

Brand-new to Android Mode. I have run a few Android Mode apps on my Galaxy 7 but wanted to develop on my Windows 10 64 bit computer with the emulator. When I try emulation itm the emulator, briefly opens up, nothing happens in it and then it closes and errors are reported in the Processing console: _BUILD SUCCESSFUL in 37s 28 actionable tasks: 28 executed Emulator process exited with status -1073741819. EmulatorController: Emulator never booted. NOT_RUNNING Error while starting the emulator. (NOT_RUNNING) Shutting down any existing adb server... Done. _

My setup: I installed the latest Processing 3.4 yesterday and the Android SDK. Here is what I get when I select to update the SDK google usb_driver 11.0.0

Hello again, I'm trying to redraw over this 2D pixel array of this program.

// main setup settings
int dimy = 800;            // screen width 1681
int dimx = 850;            //screen height 1019

int plots = 171294;        // number of plots to execute per frame (x30 = plots per second) 171294
//zoom/magnification
float magx = 4.0; // default 3.0, smaller means more zoom
float magy = magx*(dimy/float(dimx));
//pan
float panx = 0.3; //default is 0.5
float pany = 0.0; //default is 0.0
//brightness multiplier
float brt = 1.0; // brightness factor

// 2D array to hold exposure values
int[] exposure = new int[dimx*dimy];

    }
    //Return Iterate(x0,y0,DrawIt) True in Plot  
    if (key == 'R') {
     Ex = 2;
    }
}

I've studied and tested many pixel array programs recently, but don't understand it enough to figure it out the exact method. I know the pixel array exposure[] is a 2D array within the looping, nested boolean iterate(x0,y0,drawIt) and that the pixel array output is derived from the specific code:

    // Draws pixel to screen -
    // Based on if drawIt boolean is true, and iterations[i] > 3

      // Defines and Draws Pixels in 2D Exposure Array
      // Draws pixel when iteration[i] > 3 within current boolean cycle of xnew, ynew values
      if (drawIt && (i > 3)) {

         ix = int(dimx*(panx+xnew+magx/2.0)/magx);
         iy = int(dimy*(pany+ynew+magy/2.0)/magy);

         //Defines points (ix,iy) within screen ranges
         if (ix >= 0 && iy >= 0 && ix < dimx && iy < dimy) {
           // rotate and expose point
           exposure[ix*dimy+iy]++;
       }
     }

It's not a boolean true/false issue as the entire program is written in an infinite loop of nested booleans drawing, iterate(x0,y0,drawIt) and when halted either in the drawing section or the plotPlots() section the pixel array remains intact upon continuation of the program (as demonstrated with Keypressed 'r', 'R'). The program is well threaded into itself with it's booleans and I have no reason to change that fact.

How would I go about updating the entire pixel array in this program to a single color (black) upon key press? Blanking out the canvas and the program continuing it's constant pixel drawing process of exposure points on screen again without the old pixels.

Can anyone run this project to android?

https://github.com/diwi/PixelFlow/tree/master/examples/Fluid2D/Fluid_WindTunnel

I spent a weeks to find solution but nothing.

after remove unuse function (eg. mouseButton) i got this error.

* What went wrong:
Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForDebug'.
> java.lang.RuntimeException: java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex

If anyone know the solution please tell me

I am going to do the UI in VScode and I find that it cannot be executed with the .exe file I compiled. I searched and many say I should make a .bat file. I tried in my Processing but I cannot find where I can exported a .bat file. Know it is trivial, but still many thanks for your time.

Thanks Kfrajer, I tried the code and got errors while compiling...

Howdy,

I’m trying to build a simple App in processing and run it on my Google Pixel.

I already found the answer to my question, just 3 seconds after posting it here. Sorry. Here's the original post:

Using Windows 10 64bit. So I exported my sketch, and I have a .exe file that starts by double-clicking. Nothing special here, I know. However, if I drag another random file in Explorer and drop it onto the .exe file, then it doesn't open - not even a window. Investigating with task manager shows that javaw.exe opens and then instantly closes right away.

From what I read, dropping a file onto a .exe simply makes Explorer run the .exe with path to the dropped file as a command line argument. But this isn't the case, or else the sketch wouldn't instantly close and I'd be able to get the received file path by reading args[0]. (args is an array of strings that contains every command line argument received)

I want to have a .exe on which I can quickly drag and drop files and which will perform my code on such files. How?

edit: After dropping the file onto the .exe 100th time out of desperacy, it actually opened and received the file as args[0]. This removes this question immediately, but I can't find the delete button(yet), and this also sparks a new question: why it didn't work previous 99 times?

in a microservices architecture, i would like to make Processing generated applet to perform some task

You need to provide more details. Like what sort of stdin and stdout you want to work with? For stdin, you could use the args passed to a processing sketch if you run it from node.js via the exec command (not tested). The exec command is demonstrated by Shifman here:

Kf

You are using this in P3D. is this necessary? How do you display your movies?

Also, if you execute this in draw(), shouldn't it be:

if (but1_1==1 && !movie.isPlaying()) {
       println("video 1");
       movie = new Movie(this, "1.mp4"));
       movie.loop();
       movie.volume(0);
       but1_1=false;
}

Kf

Can you erase the Processing folder and download the zip again?

Remember to extract the zip and then go to the folder and run the executable. What OS are you using?

Kf

In both cases it took longer when using the P3D (OpenGL) renderer than it did with the standard Java AWT renderer.

This is not surprising because it will take longer for OpenGL to initialise because of its complexity compared with Java AWT. The size of the script will have no impact on the time to initialise the renderer.

From the users perspective waiting several seconds might seem unacceptable for a tiny Processing script to execute but perfectly acceptable for a large Processing script. In both cases the efficiency is the same.

There are many factors that can affect the start up time including

• CPU type and speed
• amount of RAM
• Operating system and its version
• GPU processor, speed, memory etc.
• OpenGL drivers (version)
• Java version
• ...

From a students perspective it probably seems worse because the code-run-code-run... cycle is very quick so any delay in executing the script can be annoying.

For a snake game, I have the food teleport to a random spot on the screen when you eat it, but it's possible for the food to end up on your tail, and not on an empty space. Basically, I sort of need some way to check if the food's x is in the arrayList for the snake's x, and the smae with y, and if so, to execute an action until that is not true.

Just to inform you, package on processing 3.3.7 is recognized as an error so I could not use the Keycode you sent me.

But based on your inputs, with research and experimentation, indicated are the following details. (Please correct me if I am wrong).

(1) I needed to use the System.exit(0); due to the reason that it is the only tested way I used to disconnect the target device with the app via bluetooth. When I don't use the indicated code, the app disconnects with the process but target device does not disconnect, creating an inefficiency in accessing app when placed on the background, which only happens when the back button is pressed.

(2) onBackPressed(); onHomePressed(); is not read in processing 3.3.7. I think that the reason to this is that, onBackPressed and onHomePressed runs in an activity and not in a fragment. And P3.3.7 executes commands in a fragment

(2) onStop(); onPause(); are affected by all buttons, that is why running System.exit(0); affected all buttons making all of the them disconnect application with the target device.

(3)onStop(); onPause(); when used in running System.exit(0); affects the app background button, giving it a minor inefficiency, wherein when the button is pressed if it is the only app on the background, there is a situation wherein you need to re-access the application twice.

(4) Based on my observation, pressing the backbutton destroys the app before it places it on the background, making the application disconnect without making the target device disconnect bluetooth connection. So due to this instead on focusing codes using onBackpress();, I used on onDestroy(); because it is not affect by the app backround button and homebutton. So applying system.exit(0); onDestroy, is just like executing the exit upon back button press.

So tested and finalized, due to the reason that the application has no more issues when pressing the 3 buttons, I used the indicated code below in exchange for the code that I used in this thread.

public void onDestroy(){ System.exit(0); }

These is a shared effort, so I will just indicate it as answered from akenaton's last response. Thank you.

I have found out that the algorithm is kind of faulty, because of lines 20-30. Only the one specific device should be updated, but instead I am updating all of them for each device. That means the number of updated devices would increase exponentially with each device added, which could result in terrible performance.

int dupdates = 0;
boolean changed;
for (ExDevice d : devices) {
    d.resolved = false;
    for (ExDevice.Pin p : d.pins) p.resolved = false;
}
do {
    changed = false;
    for (ExDevice d : devices)
        if (!d.resolved) {
            d.behavior(); // execute the behavior no matter what because some things are done in an external JS script, even if nothing is connected
            for (ExDevice.Pin p : d.pins)
                if (p.isInput) {
                    if (!p.resolved) {
                        for (ExDevice.Pin cp : p.connected)
                            if (!cp.resolved) {
                                p.level = cp.level;

                            }

            for (ExDevice.Pin p : d.pins) { // this was the faulty part: the input pins weren't checked for resolving properly
                if (p.isInput && p.resolved) {

• The sketch variable is passed to p5's constructor as a callback.
• In order to know when that callback is actually invoked, we'd need to study p5.js' source code.
• Also notice that setup() is a callback of the sketch callback.
• Until the execution reaches the alert() inside setup(), the property type had been assigned to "A" a long time ago.

@jayson You should be able to run Processing as root by executing root processing in a terminal.

Another possibility is to simply make the USB webcam available to all users, by running something like this sudo chmod 666 /dev/video*.

I've always had problems with this tool. I'm running Windows 10, and using this command:

processing-java --sketch=[path] --no-java --platform=linux --export

And it always exports just the Windows executables.

I am thinking about using --build to have more control over my build, but it's kind of inconvenient. Am I typing the command wrong?

Also I can't find any reference to processing-java in the Processing source code, so that just makes it harder for me to understand this tool.

Hi, everyone. I am now trying Processing android mode. But cant build a simple sketch.

I am on windows 7 64x and a Huawei phone with android version 4.4.4

I used p5 version: 3.3.7 And the android mode version: 4.0.1

The android sdk environment is: Google Repository 58.0.0
google usb_driver 11.0.0
Android SDK Build-Tools 26.0.2
Android SDK Platform 26 2
Android SDK Build-Tools 26.0.3
Android Support Repository 47.0.0
Android SDK Tools 26.1.1
Android SDK Platform-Tools 27.0.1

I just test the simple example:Basic-Color-Brightness I didnt modify any code but it cant run on the device

the console shows:

    Build folder: C:\Users\User\AppData\Local\Temp\android5727509137112162348sketch
    :app:preBuild UP-TO-DATE
    :app:preDebugBuild
    :app:compileDebugAidl
    :app:compileDebugRenderscript
    :app:checkDebugManifest
    :app:generateDebugBuildConfig
    :app:prepareLintJar
    :app:generateDebugResValues
    :app:generateDebugResources
    :app:mergeDebugResources
    :app:createDebugCompatibleScreenManifests
    :app:processDebugManifest
    :app:splitsDiscoveryTaskDebug
    :app:processDebugResources

and then the error in red:

error: failed to create directory 'C:\Users\User\AppData\Local\Temp\android5727509137112162348sketch\app\build\generated\source\r\debug\processing\test\brightness'.
