[minimod][v1.0.1] HitImpact - pieces of walls

[m8f]

Download

HitImpact spawns textured particles when a surface is hit.

Features:
- works for hitscan and projectile attacks,
- works for all games and mods (in theory),
- works even when loaded with old saves.

Known issues:
- Performance. HitImpact tries to minimize the amount of particles created when a lot of hits happen in a short period of time, but performance drop is still inevitable.
- Silliness. Basically, an impact particle has a version of a surface texture, and for some textures this may look silly.
- Accuracy. Don't expect physical simulation level of precision. It's approximations and compromises salad.

There is room for improvement, help appreciated!

HitImpact is a part of DoomToolbox.

This is a really nice idea and seems to work pretty much as intended. I like the idea of matching the appearance of the particles to the wall by simply using the wall texture.

However, that does lead to the "silliness" mentioned in the OP. For example, when hitting the TEKGREN5 walls near the star of map01 you can see the little band of brightness for the light on all of the particles. I don't suppose there is some way of just selecting a small area from the middle of the hit texture to map onto the particle is there?

There is ZScript Canvas which may help with that, I haven't tried it yet. Simply selecting an area from the middle won't do, because what if there is a bright switch in the middle of a texture, and the player shoots in a corner of the wall? So, I'd have to determine precisely what part of texture is hit. Which seems to be doable for hitscan, Side structure has information about texture offsets and scale. With projectiles it would be more difficult, even now I'm cheating a bit with choosing where missiles hit walls.

Not sure if it's worth it. While I was testing this (including on a TEKGREN5), a "headcanon" formed in my head, that that wall contains small pieces of electronics inside it.

Edit: maybe I can select random pieces of texture to apply to particles. Then at least unfitting parts won't show up always.

If that's doable, I think it would be fine and more-or-less logical. Obviously, sometimes the hit wouldn't be near an obvious bright (or otherwise identifiable) feature that ended up on one of the particles but I think it would probably be OK and an improvement over the whole texture being the particle. Aside from anything else, it would make the particles less hi-res looking compared to the walls.

Random pieces look much better!

HitImpact updated to v1.0.0.

New:
- random parts of textures are used instead of full texture
- sector special color support
- 3D floor support
- explosion direction improved

Fixed:
- some walls not spawning particles

Remains:
- Silliness (though reduced)

Yes, yes they do. A significant improvement. Nicely done.

Look good but acts weird with laser mod, when the laser points at the floor or walls, ceiling, it creates debris and never ends. Not sure if the laser is the issue or hit impacts.

You didn't specify which laser mod, so I'm not sure about the fix. I fixed it for my Laser Sight mod. Please try the version from here. Does it fix it for you?

[cosmos10040]

Looks like it worked! Thanks.

HitImpact updated to v1.0.1.

Fixed:
- projectiles that explode when hitting sky no longer create debris.
- NoTrigger puffs no longer create debris.

I do love this small visual touch, thank you!
