Jayenkai	Created : 17 December 2020 Edited : 17 December 2020 PHP Spritesheet Shuffler
A PHP script which. 1. Scans a folder for files named "filename_spritewidth_spriteheight_raw.png" or "filename_spritewidth_spriteheight_rawglow.png" 2. If padding is enabled, adds padding to the entire image, and sets the output to the next binary step. (eg 64,128,256,512,1024,2048) (I know that has a name, but right now I'm braindead!!) 3. Copies each individual sprite from your original sprite sheet onto the new sheet, leaving padding if required, and stripping out Magenta and Cyan from the output. (255,0,255 & 0,255,255) 4. Saves back out as a plain sprite sheet with transparencies where required, and again with IDs for each sprite on the sheet. 5. If the filename ended with rawglow instead of just raw, then it adds a blurry glow, and saves that version as G_filename.png (Note : This is slow!!) 6. If you've set a DupFolder, it places another copy of the final spritesheet in there, too. <?php $lf=chr(13).chr(10); echo '-=-=-=-=-=-=-=-=-=-=-=-=-=-'.$lf; echo ' Sprite Padder'.$lf; echo ' and'.$lf; echo ' Transparency Doohickey'.$lf; echo ''.$lf; echo 'A simple enough PHP script,'.$lf; echo ' by Jayenkai'.$lf; echo ' AGameAWeek.com'.$lf; echo 'with help from'.$lf; echo ' Rychan : @refreshgamesuk'.$lf; echo '-=-=-=-=-=-=-=-=-=-=-=-=-=-'.$lf; // -=-=-=-=-=- // Settings // -=-=-=-=-=- $pad=1; // width of padding around each sprite $countfix=1; // If I can fit "n and a bit" sprites on a row, // should the first one on the second row be n, or n+1? $strip=0; // Whether to remove the width/height when deciding on the filename $DupFolder="../../asset/"; // If you want a duplicate version of the file to be saved. // -=-=-=-=-=- // Code! // -=-=-=-=-=- $flist=scandir('./'); for ($n=0;$n<count($flist);$n++) { if (substr(strtolower($flist[$n]),-8)=="_raw.png") {Conv($flist[$n],0);} if (substr(strtolower($flist[$n]),-12)=="_rawglow.png") {Conv($flist[$n],1);} } function Conv($filename_raw,$glow) { global $lf,$pad,$countfix,$MaskA,$MaskB,$DupFolder,$strip; $fz=0; $fzw=0;$fzh=0; $filename=substr($filename_raw,0,strlen($filename_raw)-4); $filename_rawless=substr($filename,0,strlen($filename)-4); if ($glow==1) {$filename_rawless=substr($filename_rawless,0,strlen($filename_rawless)-4);} $bits=explode('_',$filename); $c=count($bits); if ($strip==1) { $filename=$bits[0]; $filename_rawless=$bits[0]; } if ($glow==0) {echo 'Conv : '.$filename.'

Daren't test with PHP8, it'll probably implode!!
