ZDoom

Yum: Agreed, but I've heard back from nobody on the Zandronum team who can give me a clear cut answer on if I may use their resources with permission, so this is off the table entirely until either someone decides to make sprites for me or they respond with a resounding 'yes'. Only then will I make a PR for this.

Some weapons mods (like mine) already use PowerWeaponLevel2 for other things, I use it for an akimbo weapon. So unless ZScript can add new powerups, this is impossible to DIY while still having my guns akimbo for instance.

I'll file this off as 'DIY'.

How I'd implement it:

1. Change Weapon.SisterWeapon to accept a numerical value. 0, 1, 2 and nothing all mean PowerWeaponLevel2 for backwards compat, and 3 would be PowerWeaponLevel3, which would be the Spread rune. The Weapon.SisterWeapon value would need to be the same obviously.

I think two things are needed for the theoretical spread powerup:

* Allow weapons to opt out from implicit powerup handling, meaning it handles that itself somehow.
* If the weapon doesn't opt out, hitscan/projectile attack functions aim the attack by whatever angle the spread is supposed to be to the left/right and then finally perform the normal attack. Since IIRC they use a helper attack function there is no need to add a dirty hack to all the attack functions and the changes can be consolidated to the respective hitscan/projectile helper functions.

Interesting. I'll see if I can reach out to Carnevil then, if he's still around.

Also been pondering about adding ot her zandronum elements, i.e. doomsphere, and the skulltag specific health/armor bonuses, wonder if folks would approve...

The assets themselves are mostly derived from Doom alpha sprites, IIRC.

I thought you would have to ask Carnevil. Didn't he copyright them or something?
If I remember correctly, there was some issue relating to Carn that stood in the way of Skulltag's assets being included in Zandronum rather than being in a separate pk3. I could be wrong though.

How should I handle adding credits for where they're due? In the event I get permission to add them into GZDoom. And, should they be part of the GZDoom extras .pk3?

My first thought was, what if there could be an in-between point where the functions call on a virtual that's executed on the powerups, like ModifyDamage is called for taking damage. But... that might generate recursion issues.

I think I'll leave it out for now in the mean time.

The only clean way would be, like I said, as a powered up sister weapon with its own attack sequence. But that'd come with its own set of problems.

Realistically I'm not sure how the spread effect as it exists in Skulltag could be handled cleanly. Perhaps it's best to leave it behind.

The most obvious thing would be to make that rune activate the regular weapon powerup and define the alternative fire modes as the powered up sister weapon.
But I have no idea how that might interfere with existing mods that already use the feature.

How would you prefer it be handled instead? Or should it be outright excluded?

It added some hacks to the actual firing functions - which is an absolute no-go because it's too restrictive and very, very dirty.
