SpriteShadow (Duke3D Shadows) v1.9 (calling mod authors)

Adds shadows under monsters, like in Duke Nukem 3D. Works with all monsters and players, for any game and with any mod. Autoload ready.

Requires GZDoom 4.1.3 or higher!

Update July 10th 2019 (version 1.9)

- GZDoom version bump to 4.1.3.
- Do not serialize shadows. This means the shadow actors do not get written into saved games. Might help with multiplayer saved game stability.
- Github repository added.

Spoiler: "Old Updates"


Known Bugs or Limitations:

- Shadows are ignoring player's crouching sprite frames for some reason
- Looks like crap when sprite billboard mode is set to XY. Monsters look like crap with this setting even on vanilla so I don't recommend it anyway (why was this option even added, ugh)

If you find any other bugs, please let me know.

Have fun!

Glad to see you didn't give up on this despite the guy who originally asked giving up on it so quickly. :)

I don't remember how it was in Duke3D, but if there's a ledge, won't part of the shadow end up hovering in the air?

Yessss! I've wanted something like this for a long, long time!

Honestly, making this work with EVERY actor may not actually be a good idea - not every actor will look good with this, resulting in weird things like shadows for fire on torches etc.

Fucking hell, this is incredible.

Dumb question, but just to make sure, would it be all right if I nicked it for use in my own projects?

Kinsie: I think I can limit it to actual living monsters by just doing a check for the +ISMONSTER (bIsMonster in ZScript) flag, although of course this won't be 100% fool proof against people who are doing hacky things with Things that aren't supposed to be monsters but are still flagged as such...

TerminusEst13: Have fun! When/if I update this to be more modular, I'll update this thread. I don't think the way I did it in that proof of concept is the best way (I can't imagine copy/pasting all that into every monster definition... a better way would be if this thing just works in the background with minimal code)

Additionally, I'm not feeling too good about that hack I did to force the shadow to be drawn under the monster (that is, spawning the shadow -> spawning a copy of said monster -> destroying original/map-placed copy of monster, in that order)... o_O

Yeah, there's definitely a lot of avenue for tweaking to make things more streamlined, but I think that's half the fun of things like this. It's like a puzzle game!

You'll probably solve it first, but I still like fiddling and experimenting. :D

Thank you very much again for this!

This looks very interesting! Hopefully you figure out a way to do this for everything.

Do you really need to extend Actor to do this across the board? It's only monsters that generate this effect in Duke, right?

(/me might be posting without any real idea of how much ZScript is/isn't capable of)

Yes, because if I don't extend Actor, I'd have to end up coding the functionality and a bunch of "replaces" for EVERY kind of monster (what I am doing in the latest version of the WAD in the OP). And it won't cover mod monsters without manual intervention.

The whole point of putting it in Actor is so that every monster in any mod, ever, will have the functionality, because when it boils down to it, everything you place in the map descends from Actor.

Simply checking for bIsMonster is enough to filter the effect to only happen on actual, living monsters... should be a non-issue, in most cases. So don't worry, the shadows won't be spawned for items, decorative stuff, etc...

(and again, I am already doing a monster check in the WAD in the OP - this shadow won't appear on the player, even if you give yourself the item - it will only appear on monsters)

Very impressive work, congraulations for this showcase of the capabilities ZScript has :)

Nash, I gotta say this is a gamechanger. It looks good in screenshots, but actually playing is incredible. I never knew how much I needed this until now. This tiny change makes Doom look so much better.

Thank you! I really want to make this modular and be autoload-friendly, so I'll just wait for "extends Actor" to be possible.

I also could submit it as a GZDoom feature but I think that's way out of scope for base engine functionality.

EDIT: Found a bug

Monsters that disappear when dying (Lost Soul, Pain Elemental) will leave their shadows behind despite their corpse not existing anymore. Will be fixed for next version
