Hi forum,

I think I found a bug. The following works:
1. int[] w = {};
  w = append(w,4);
  //-----------
  String[] x = {};
  x = append(x,"Test");
  //---------
  float[] y = {};
  y = append(y,4);
While this doesn't work:
1. long[] z = {};
  z = append(z,4);
Should this not be a bug please explain to me my error.

Thank you!

Hi Forum,

How could I make processing do something when any key has been pressed for longer than 3 seconds?

Thx

Change (close one and open&run another) Processing file.

Hi Forum,

I guess closing one is easy, just use
1. exit();
But how can I get Processing to open and run another pde (not an applet). Is this possible?

I cant just forward it to a website where I saved the applet because I am using this Library TTS.

This would need to run in Windows and Ubuntu, not Mac.

Thank you

Delay in a void

Hi,

I don't get why this is not working. I know that the delay function is not ideal, but I don't know an alternative...

This is a little bit more complicated. We got a code from our teacher with which we could work. This is what you need to know to understand the code:

rfR is a sprite.

display displays the sprite at a given point (this point is not given in the code below)

hit gets the width and height of playerR and rfR and checks if they overlap.

What doesn't work? The delay function seems to stop the whole program, not just the void. Is this normall?

Heres the simplified code:
1. int r2, powerup;
        void setup()
              {
                    size(500, 700);
                    frameRate(5);
  
                    r2 = (int)random(8258, 16789);
                    powerup = powerup = (int)random(7890,19321);
              } //end setup
  
  dispRFr = 0; //display rfR when this = 1
  spL = 5;
  
        void draw()
              {
                     if(millis()>=r2)
                           {
                                  dispRFr = 1;
                     }
                     if(dispRFr == 1)
     {
                            rfR.display();
                            if(playerR.hit(rfR))
                                   {
                                         spL += 10;
                                         dispRFr = 0;
                                         rfRwait();
           }
  }
               } //end draw
  
  void rfRwait()
        {
              delay(powerup);
              spL -= 10;
        }
Thx for the help

Random in if

Hi Forum,

I cant get this part of my program to work. What am I doing wrong? Do I need to "start" the millis somehow?
1. if(millis()<=random(8258,16789))
  {
  somecrap
  }
So after 8258-16789 milliseconds "somecrap" is suppost to happen. It is not :(

Processing is not giving me any errors...

Thx in advantage :)
