I would like to load a text file that is outside of the data folder. I can get the full path but loadString seems to need a file inside the data folder.

Thanks in advance.

Hello, I'm trying to catch every click on my interface so that something is only drawn in my draw event when the mouseclick was not on the interface. I have this at this moment:

1. class MyControlListener implements ControlListener {
     void controlEvent(ControlEvent theEvent) {
     UI = true;
    }
   }

But this seems to not change the variable at all. With listener I was able to catch mouseclicks on groups but not on buttons,sliders,radiobuttons and dropboxes. I wonder if anyone knows the answer.

Thanks in advance.

I'm trying to draw a 16x16 grid made out of rects (drawn with rect or line) but both are terribly slow. I know trying to draw 3600 rects/ 125 lines isnt very fast but I need this. Maybe there is something wrong with my code or it could be done in a faster way. Please let me know.

1.   for (int i = 0; i < width/16; i++) {
       for (int j = 0; j < 45; j++) {
           rect(i*16,j*16,i*16,j*16);
       }
     }

I'm compiling this for Android 2.3.4 on a Sony Xperia Play and have the Test.svg file in the data folder.

1. PShape s;
   
   void setup() {

     smooth();
     noLoop();
   }
   
   void draw() {
     shape(s, 10, 10);
   }

Thanks for any help

Hi, I wanted to create a delay in my game once for a second and searched for a function and found the Delay(); function but the wiki says:

delay() has been removed. Nobody understood what it did, and when they did, they didn't understand why it was there. Huge source of confusion, especially for beginning students.

So how can I reproduce the effect of this function?

Thanks in advance.

Hello, I'm using processing to create an android game but I have a problem. When I try to rotate a rectangle to the mouse it rotates way too fast. I tryd this code out in gamemaker and it worked perfectly. It rotates way too fast in the .exe too.

Here is my code:

1. // Build a container to hold the current rotation of the box
   float boxRotation = 0;
2. void setup() {
     // Set the size of the screen (this is not really necessary
     // in Android mode, but we'll do it anyway)
     size(480,800);
     // Turn on smoothing to make everything pretty.
     smooth();
     // Set the fill and stroke color for the box and circle
     fill(255);
     stroke(255);
     // Tell the rectangles to draw from the center point (the default is the TL corner)
     rectMode(CENTER);
   }
3. void draw() {
     background(mouseY * (255.0/800), 100, 0);
     boxRotation = direction_to_point(width/2,height/2,mouseX,mouseY);
4.   // Draw the ball-and-stick
     line(width/2, height/2, mouseX, mouseY);
     ellipse(mouseX, mouseY, 40, 40);
5.   // Draw the box
     pushMatrix();
     translate(width/2, height/2);
     rotate(boxRotation);
     rect(0,0, 150, 150);
     popMatrix();
   }
6.   public float direction_to_point(float tempx1, float tempy1, float tempx2, float tempy2)
     {
       float xd = tempx2 - tempx1;
       float yd = tempy2 - tempy1;
       return 360-90*( 1 - signum(xd) - 2/PI*atan( yd / xd ) );
7.     //this is the problem^^
       }
    
     int signum(float f) { 
     if (f > 0)
     return 1; 
     if (f < 0)
     return -1; 
     return 0;}

Thanks in advance.
