Redefined weapons with EDF, now berserk no longer autoswitches

Recommended Posts

I redefined the DoomMarine player class as follows:



playerclass DoomMarine
   defaultskin    marine
   thingtype      DoomPlayer
   altattackstate S_PLAY_ATK2
   superhealth    200

   default true

   weaponslot 1 { weapons : CoolChainsaw, CoolFist }
   weaponslot 2 { weapons : CoolPistol }
   weaponslot 3 { weapons : CoolSuperShotgun, CoolShotgun }
   weaponslot 4 { weapons : CoolChaingun }
   weaponslot 5 { weapons : CoolMissileLauncher }
   weaponslot 6 { weapons : CoolPlasmaRifle }
   weaponslot 7 { weapons : CoolBFG9000 }
   weaponslot 8 { weapons : CoolChainsaw }
   weaponslot 9 { weapons : CoolSuperShotgun }

// rebornitem AmmoClip, 50
   rebornitem CoolPistol
   rebornitem CoolFist


The only difference between these weapons and the regular ones is the tic duration of the fire sequence, which is slightly faster. For example, the fist:


weaponinfo CoolFist : Fist, 0
	selectionorder 9.0
		PUNG B 4
		PUNG C 3 A_Punch
		PUNG D 4
		PUNG C 3
		PUNG B 5 A_ReFire
		goto Ready
	sisterweapon EpicFist

The sisterweapon is the same but even faster, obviously a tome of power variant.


The problem is, picking up a berserk pack no longer auto-switches to the fist, and I can't figure out why. It might have to do with selectionorder, but if I don't put that there, the old selectionorder is not inherited. I hope one of the devs can help me here; is this a bug or am I missing something?

You probably need to add a "pickupeffect BerzerkBox" definition with a "changeweapon CoolFist" in it (in a custom "sprites.edf" file).

This isn't reaallly a bug. The BerzerkBox references the Fist weapon directly. To avert this issue I'd suggest using deltas instead.

    name DoomMarine

    // The below won't work until the next DRDTeam build
    // Pistol ammo used to be here but now it's long long gone
    rebornitem Pistol
    rebornitem Fist

This is what the delta for fist would look like. I think there will still be issues if you're tomed whilst you get the powerup. I'll need to think about suitable fixes for that. I have an idea for one but I'm sure there'll be some weird edge-cases. Frankly I'm surprised people are even using the tomed weapon stuff so soon. Makes me nervous about comitting stuff in devbuilds that I might want to change prior to a major release.

    name Fist

		PUNG B 4
		PUNG C 3 A_Punch
		PUNG D 4
		PUNG C 3
		PUNG B 5 A_ReFire
		goto Ready
	sisterweapon EpicFist

I lied about DRDTeam I'm just gonna attach an exe w/ the changes so you don't have to wait. Here you go: Eternity.7z

What attracted you to use inheritance instead of deltas, if I may ask? My goal here is to try identify how to adjust to docs so that in future the best course of action is more obvious.

You're the best. Unfortunately the delta solution doesn't quite work as intended for a few reasons:


- The weapondelta entry, for whatever reason, uses the sisterweapon's attack speed

- Using playerdelta like that doesn't account for the rest of the weapons (I also defined WeaponGivers, just didn't post them here)

- For whatever reason, I am unable to switch to the pistol regularly, even after using "rebornitem CoolPistol"



- When running out of pistol ammo, or any other situation which causes a switch to the fist, the game crashes:

Probably my (limited) past experience with GZDoom's DECORATE. Seems more straightforward to me, since I've had a shot at redefining player classes that way in the past. Also, I didn't really know what deltas were. It seemed simpler to just copy the relevant information from the Doom EDF files and change only what I needed to change. All things considered it works pretty much exactly how I want. I'll probably use @andrewj's solution and just work around the sisterweapon problem when it comes up. I'm kind of dumb, I didn't even think to redefine the BerzerkBox.

Won't quote for brevity, but your dashed points in order:

  • Thaaat sounds like a really bizarre bug. That needs fixing.
  • You should be able to add the rest of the weapons too just fine to the delta.
  • I'm not quite sure about this one. Also sounds like a bug.
  • A crash is a crash. I fixed most of these sorts of bugs but I'm not surprised a few linger.

Would you be able to provide me we any WIPs (privately if you want) that I can test and fix this with? The third point you have it'd also be super helpful if you could figure out the circumstances of being unable to switch to the pistol.

PM'd. Some clarification:


- Disregard points 2 and 3, those were on my end.

- The sisterweapon attack speed is only upon initial spawn. After switching to the fist again it works as intended. In fact, when picking up berserk it even "switches" to the regular version.


It's probably still on my end, I don't really know what I'm doing :/

OK thanks. I might be a smidge slower to react to this than the past couple things. Contrary to quick changes I made recently I expect to be inundated with work fairly soon.

For a line like `weaponinfo Foo: Bar, 8` you don't need the `, 8`. That is the dehackednum, and is for internal use only, basically.


The crash and wonky starting weapon are due to your 'Epic*' weapons having a selectionorder. I just realised now, but weapons with POWERED_UP cannot have this property set so I've explicitly disallowed this and it will cause an error at startup if it occurs from now on.

The wonky starting weapon in particular happens because when you have two weapons with the same selectionorder which are eligible for being chosen the one with the lowest alphabetical value is chosen. Following this, EpicFist is chosen over Fist. It worked before because CoolFist comes before EpicFist alphabetically. When a player is spawned the "best" weapon is chosen by picking the weapon the player owns current w/ the lowest selectionorder (falling back on the alphabetical check).


You don't need to specify selectionorder in a delta unless you're actually changing it, for what it's worth. Inheriting weapons do need their own selectionorders for the moment to actually end being autoselectable once you run out of ammo, but I might change that. I'm not sure if I intentionally made it that way back when I first implemented it...


Anyway in the meantime I'd suggest using deltas and remove selectionorder from the powCancelered up weapons. The code change I made only adds an error message.


I appreciate you reporting these issues, by the way. Helping find these edge-cases is super handy. Let me know if there's any further problems.

That works! Good info to know. I probably would have used deltas had there been more info on it (I don't think there's any examples of weapondelta or playerdelta).


Also, unfortunately, I did find one more thing... if the tome of power variant is active upon exiting a level, the active weapon stays "powered up" to the next level until another one is selected. I've implemented weapondeltas for all non-powered versions and removed all selectionorders in the weaponinfo definitions. I'm sure there's some way to work around this with ACS, but maybe there's an easier method.
