General / Re: Weird rom list navigation

« on: January 01, 2023, 04:44:55 PM »

I was pulling my hair over this and I wasn't able to pull off anything useful from the source code, so I made a fix with some custom squirrel code:

Hope this helps anyone struggeling with that issue.

Scripting / Fixing "next/prev_letter" hanging on certain titles.

« on: January 01, 2023, 04:36:53 PM »

This is my fix for AM hanging on letters when the "Title" has a different case as the previous entry, has special or numeric chars in it or other reasons as the famous "vs." or ", The" hanging.
Pre-sorting your romlists by "Title" (2nd entry in the csv file) helps.
I hope I correctly copied this from my layout file. Pls let me know otherwise.


Layout:

Code: [Select]

//////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
// Fixing next_letter / prev_letter /////////////////////////////////////////////////////////////////////////////////////

::current_signal <- "";

function setCurrentLetterIndex() {
    ::print("setCurrentLetterIndex()\n");

        if(::letterIndexes[i] >= fe.list.index) {
            ::currentLetterIndex = i-1;

I think I managed to get rid of the screensaver by disabling DPMS with "xset":

Check for any blanking, screensaver, timeouts and DPMS (Energy Star) with

Code: [Select]

xset q

Disable DPMS:

Code: [Select]

xset -dpms

Don't forget to add these to a script and execute it on startup.

I have decided to use 2 layouts, one for menu and one for lists.
Now, if I wanted to return from a display straight into the last viewed system I need to fill and read a global variable.

In my menu layout:

Code: [Select]

if(::last_display_index){
    jumpToSystem(::last_display_index);
}else{
    jumpToSystem(0);
}

and in the Emulator/List layout:

Code: [Select]

::last_display_index = fe.list.display_index;

This kind of declaration must be wrong, because I always get "The index last_display_index does not exist."[/s]


edit:
The solution to this was rather simple...

Code: [Select]

local sys_index = fe.list.index;
local sys_index_name = fe.displays[sys_index].name;
my "sys_index" controlls the system to show.

Unfortunately I already tried every grub-related solution prior to my post and none of those work for me.
Must be something related to X, I dunno.

Not sure what a screen blank is.

or a console-blanking, when the screen turns off - a screensaver.
as I said I already went for the grub-option but it's not working.

RetroArch has some kind of disabling that works a charm...

I'd like to share this set of voices I made while experimenting with Attract Mode layouts...

Maybe someone finds this useful.

Is there a opposite method for add_x? Like remove_image and remove_artwork?

Also, I see that the base for positioning a video is top/left. Could it be that this is different for images?
When I do

Code: [Select]

fe.add_image("myImage.extension", 0, 0, layout_with/2, layout_height/2);it looks like the horizontal center is off to the left...

I'm still struggeling to disable the screen blank in AttractMode.

Another day - another question...

When I create a surface to "group"  images that are aligned horizontally,
must it be the exact size of the layout?

I'm asking because when I create a surface that is 10x wider than the layout it just disappears...

I had the same solution, but without the "::" (What does it mean?)

But it doesn't seem to work:
Script Error in /opt/retropie/configs/all/attractmode/layouts/012019-menu/layout.nut - the index 'sys1' does not exist

edit:
ha! Got the solution here: https://developer.valvesoftware.com/wiki/Squirrel#Tables

The assignment outside a table has to be a key/value pattern with "<-" instead of an equal-sign :-)

Thanks!

I'm looking for an elegant way to create this by the number of displays with a loop:

Code: [Select]

::OBJECTS <- {
sys0 = "",
sys1 = "",
sys2 = "",
sys3 = "",
sys4 = "",
sys5 = "",
sys6 = "",
sys7 = "",
sys8 = "",
sys9 = "",
sys10 = "",
sys11 = "",
sys12 = ""
}

It's coming together.. bit by bit, thanks guys!

Is there a way to prevent AM from jumping into another Display when I hit left or right in the "Displays Menu"?
I'd like to do custom stuff when up/down/left/right is pressed and I can't find a way to unbind the default signals/actions.

edit:
I think I solved this one...
I'll post my code when it's ready.

With your help I already sorted some problmens I had out, thanks!

Is there a way to re-assign the signals or the way a listbox is navigated?

I'd like to have a horizontal control scheme on start in the displays-menu, then a classical list - a bit like EmulationStation works.
My idea is to position a list and set it to ".visible = false", then animating the system-logos on a horizontal line.
Now I guess I just need to tell the list it has to react to "left/right" instead of "up/down" by manipulating the default signals...?




Is there something like dynamic assignment?

In other languages this might work:

Code: [Select]

array = {1,2,3,4,5};
which_element = "element_" + array[0];
which_element.animate(); // -> should be the same as: element_1

or like this

Code: [Select]

for(i=0;i<10;i++){
    ["element"+i].doSomething;
}

in other words: is there a way to make up an object's name out of a string + a variable and then do something with it?

Another thing that I can't sort out is the screensaver.
I'm on Ubuntu Server 18.04 LTS and already added the console blanking command to my grub file.
In RetroArch, when a game is running the screen will stay on forever, but in Attract Mode it blanks after a short time.

I dunno how it's done in RA but I'd love to disable any (system-)screen blanking or screensaver for good.
(this is not related to AM-screensaver)

If anybody has an idea, I'd love to hear it.
