Reset Scipt

Hi there,

Can someone tell me how to reset a script? Or to get is to run on a schedule?

Thank your for your help in advance...

It depends on what's gone on in the program beforehand. Basically, you'll have to write it yourself to make a script that will change everything back to how it was when the program ran for the first time.

Hi Manic,

Thanks for your reply. I'm still a bit lost. I'd like to start  and stop a sketch at 8am and 5pm. I - as you can tell - am completely new to Processing. Is it in the void setup I'd do that?

Thanks,

Rob

well, you could just put whatever code you want to run inside an if statement like this;

Quote:
if(hour()>8 && hour()<17){
 //commands go here
}

But that won't reset the settings.

I'm guessing you want/need to run this program in a public place.

I would recommend creating an object called Exibition or whatever, so every time you want to reset the program, you just create a new "Exibition" object with the original parameters.

Example

Code:

class Exibition{
    float value;

    Exibition(float value){
	  this.value=value;
    }

    void drawExibition(){
	  //your code here
	  println(value);
	  value++;
    }
}


and

Code:

Exibition exibition1;

void setup(){
    size(800,600);
    exbition1=new Exibition(1); //original parameters here
}

void draw(){
    if(hour()==8){
	  exibition1=new Exibition(1);
    }
    else if(hour()>8 && hour()<17){
	  exibition1.drawExibition();
    }
}


This way, whenever the clock hits 8am a new "Exibition" object will be created on top of the old one, with the original parameters (in this case the value 1). If the clock is between 8am and 5pm it will execute the "drawExibition" function, which will actually work as the regular "draw()".

I believe the "hour()==8" might fail because if the frame falls in between a fraction of a second before or after it will not be executed,but I think that can be solved easily.

Thus, you will actually create a new exibition every day, rersetting things to its original state.

It might be overkill for your case, but I've found out it helps to simplify bigger code.

An interesting way to do resetting of papplets:

Code:

import java.lang.reflect.*; //important!
class vars { //INITIAL VALUES BELOW
    int seed = 3;
    float[] weird = new float[]{3.0f, HALF_PI, 452.f};
}
int seed; //will be initialized with above values
float[] weird;

void setup(){
    size(640,480);
    recreate(); //True setup
}
void recreate(){
    //Ignore this code if you don't understand 
    //(it's complex, but does cool stuff!)
    Class thisclass = getClass();
    Class[] inner = thisclass.getDeclaredClasses();
    for(int i = 0; i < inner.length; i++){
	  if (inner[i].getName().equals("vars")){
		 thisclass = inner[i];
		 break;
	  }
    }
    Field[] toUpdate = thisclass.getFields();
    Field[] myUpdate = getClass().getFields();
    vars copier = new vars();
    for(int i = 0; i < toUpdate.length; i++){
	   for(int k = 0; k < myUpdate.length; k++){
		  if(myUpdate[k].getName().equals(toUpdate[i].getName()){
		myUpdate[k].set(toUpdate[i].get(vars));
		break;
	 }
	   }
    }
}

int lastChangeOnAM = false;
void draw(){
	if (lastChangeOnAM){
	   if (hours()>16){
	   recreate(); //Reset to values in class vars
	   lastChangeOnAM = !lastChangeOnAM;
	  }
	} else {
	   if (hours()>8){
	   recreate();
	   lastChangeOnAM = !lastChangeOnAM;
	   }
	} 
     //Code here that will reset on 8:00 and 16:00
}
