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;
            return;
        }
    }
    ::currentLetterIndex = (::letterIndexes.len()-1);
}

function buildLettersArray() {
    ::print("CurrentList: "+fe.list.index+" of "+fe.list.size+"\n");
    ::currentLetterIndex <- 0;
    local list_size = fe.list.size;

General / Voice-over for layouts

« on: February 02, 2019, 06:43:42 PM »

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

Maybe someone finds this useful.

Scripting / Diving into squirrel-scripting: some questions

« on: January 30, 2019, 01:26:04 AM »

Hey guys,
I'd like to thank you for all the efford that went into attract mode. Having the freedom of doing so much with it is just awesome.

I'm creating a layout for a 240p-setup to be outputted to a crt and ran into some questions I'd like to sort out.
First issue is with the default font and missing font-size parameter for it:
The font-size is calculated by the layout's size. Mine is 320x240 so the font in my "Configure"-menu is appx. 8px in height, which is okay as long as I use a pixel-font that was created with 8px height in mind. The help-messages on the bottom of the menu are rendered smaller, appx 5px in height in my layout, so again, if I use a font like "CG pixel 4x5" those texts display just fine but the menu-items don't display properly because the 5px font is stretched to a height of 8px.
I would love to see some more parameters to target this issue maybe sometime in the future development of attract mode.
Next is a scripting question about creating a condition for "DisplayName". This does exist as a Magic Token so it can be used in "add_text" but when I want to create a condition I fail to do something like this:

Code: [Select]

if([DisplayName] == "Displays Menu"){
    // code for the layout where I can select the different displays/systems
}else{
    // code for layouts that relate to a display/emulator/gamelist
}I use snaps with a low alpha value in the background and titles as a small preview image in my layout. When a display has a lot of entries in its gamelist I see performance issues while navigating through the list of games, so I'd like to remove all media while browsing and add it back to the layout after a delay-timer counted to a given value. I've seen concepts like this in other threads but I have to ask:
How can remove an image or artwork and use a function to add it to the layout.
Something like this, called on transition-callbacks doesn't seem to work:

Code: [Select]

function showImage(){
    fe.add_image(...);
}
I sure have some more questions, but for a start this is enough ;-)


Thanks, any help with this is very much appreciated!
