Scripting / Re: Last played games

Does attract mode load the romlist after return from game? If so, you could use a plugin that will modify the romlist during to game transition, all in squirrel.

Scripting / Re: crt_lottes horizontal scan lines?

So I was looking at the slightly modified version of lukem nukem / crt lottes in flat blue theme.

Can anyone explain the difference to me between rotated and vert params?

Here’s the screensaver code I created. It should be enough to get you going on an object that will take care of what you want. Its essentially the same concept of doing something after a period of inactivity.

In this example, I used FadeArt to display video and had all other elements on the surface „osd“. That surface would disappear leaving just the video as a screensaver to prevent screen burn in. Could also modify it to select random games as well.

Code: [Select]

//
// ScreenSaver
//

class ScreenSaver {
  active = false;
  delay = null;
  fade_time = 50;
 
  time = 0;
  last_signal = 0;
 
  constructor( sec ) {
    delay = sec.tointeger()*1000;
   
    fe.add_ticks_callback( this, "Timer" );
    fe.add_transition_callback( this, "LastSignal" );
    fe.add_signal_handler( this, "BlockSignals" );
    fe.add_ticks_callback( this, "Start" );
    fe.add_ticks_callback( this, "FadeOut" );
    fe.add_transition_callback( this, "End" );
  }
 
  // private functions
 
  function Timer( ttime ) {
    time = ttime;
  }
 
  function LastSignal( ttype, var, ttime ) {
    last_signal = time;
  }
 
  function BlockSignals( signal ) {
    if ( active )
      return true;
    return false;
  }
 
  function Start( ttime ) {
    if ( !active && ( ttime >= last_signal + delay ) )
      active = true;
  }
 
  function FadeOut( ttime ) {
    if ( active && ( osd.alpha != 0 ) )
      osd.alpha -= 255/fade_time;
  }
  ^%≥÷∂f,-p;
  []\]\]
  function End( ttype, var, ttime ) {
    if ( active ) {
      active = false;
      osd.alpha = 255;
    }
  }
}

if ( config["screensaver"] == "Yes" )
  local screen_saver = ScreenSaver( config["screensaver_delay"] );

« on: July 30, 2017, 03:43:20 PM »

Yes. I've done it. I'll see if I can find the code tonight or tomorrow. Here's a basic outline from memory of what I did.

Create an object with tick and timer variables. Object has a tick function that updates the tick variable so it can be used in other object functions. Same function or separate function will also will add time to the timer variable. If timer variable reaches limit, then do whatever you want. Object also has function that listens for key press and resets timer back to zero.

That's what I did to implement my own screensaver.

You can store Params and variables in autohotkey. I've done it. I never thought about illegal characters. Is it possible you can escape them?

I know you can store variables in AHK, my problem is how do I get them from AM? Is there a way to output them from AM, so they can be used in an AHK script? I don't know how you take the variables from AM and make them something an external AHK script can use.

The same exact way as in your thread!

See the ahk docs: https://autohotkey.com/docs/Scripts.htm#cmd
