Eight Direction & More Frames

[LunarBerry]

Hi, first off this is a really handy and efficient setup. I love how it'll read normal/default sprite sheets and then has the ability to setup custom ones. Cause our project requires the main characters to have more actions, while NPCs etc. are to just have the game's default setup (as NPCs don't require much more movement than just walking around). I've actually worked to making diagonal facing sprites but have no real way of implementing them when using this script. I even tried using another script in hopes it'll keep this one functioning but will call on the diagonal/quarter version but it brought it to read like a single set sheet for walking.
Is there a way to make a script call from within the script to read another set of templates for the "_custom" sprites, to act as diagonal facing (or assign them to the "diagonal" keys") and still work the same way? Not worried about default/NPC sprites as we're not worried about them doing much and if it does, that can be done in another method, so the way it's reading basic sprites is perfect. It's cool in keeping to one sprite sheet, but I don't mind setting up a separate sheet for that. Or perhaps is there another separate script out there that might do the trick? You mentioned Frank's MultiPose script. Does this script provide this effect I'm looking for?
Any help is appreciated ^^

In case you're wondering, I tried implementing Paradog's script with some minor script edits while using a "_quarter" version template copy of the provided sprite sheet in your demo (just made everything reversed so i could see any differences) and as mentioned, in a weird way it worked but wasn't reading the other poses/actions in the sheets, just the first set. Dash function still worked but was still reading the first walk set. ^^; That and I think it's also effecting the "npc"/default sprites as in trying to read a diagonal version which there wouldn't be any (which is also not needed anyways). So that didn't work out well. X_x;;
