Shoot from weapon "without" player

[Apeirogon]

Lets take a simple doom pistol. Is it possible to make it shoot without using it as player ready weapon?

[Void Weaver]

What do you mean "make it shoot without using it as player ready weapon"? How it supposed to acts directly in game?
Do you mean doing call A_FireBullets outer of 'Fire' state or something else?

[Apeirogon]

Execute weapon "fire" state without using them as Psprite.

[Void Weaver]

... what about replacing fire-Psprites by other custom ones or even TNT1?

For ex.:

Code: Select all

ACTOR InvPistol : Pistol replaces Pistol
{
  Weapon.SlotNumber 2
  Weapon.SlotPriority 1
  States
  {
  Ready:
    TNT1 A 1 A_WeaponReady
    Loop  
  Fire:
    TNT1 A 4
    TNT1 B 6 A_FirePistol
    TNT1 C 4
    TNT1 B 5 A_ReFire
    Goto Ready
  Flash:
    TNT1 A 7 Bright A_Light1
    Goto LightDone
    TNT1 A 7 Bright A_Light1
    Goto LightDone
   }
}

[Apeirogon]

Such possible in zscript without replacing actor.
I need a way, if it possible of course, to shoot from weapon directly from inventory. Like panic button to shoot from shotgun/pistol/etc without picking them up as weapon.

[Void Weaver]

Oh, seems I've got it. I guess this can be easily done at ZScript, but unfortunately I can provide only decor example.

That Shotgun can fire Missiles when alt-fire pressed at any part of Ready\Fire sequence without breaking shooting sequence or playing any RLauncher sprites:

Code: Select all

ACTOR AssaultShotgun : Shotgun replaces Shotgun
{
Weapon.SlotNumber 3
Weapon.SlotPriority 1
States
{
Ready:
SHTG A 1 
{
A_WeaponReady(WRF_ALLOWRELOAD|WRF_ALLOWUSER#);
If(GetPlayerInput(INPUT_BUTTONS)&BT_ALTATTACK)
{A_Overlay(2,"MissileShot");Return state("");}
Else{Return state("");}
}
Loop
  
Fire:
SHTG A 3 
{
A_WeaponReady(WRF_NOPRIMARY|WRF_ALLOWRELOAD|WRF_ALLOWUSER#);
If(GetPlayerInput(INPUT_OLDBUTTONS)&BT_ATTACK&&GetPlayerInput(INPUT_BUTTONS)&BT_ALTATTACK)
{A_Overlay(2,"MissileShot");Return state("");}
Else{Return state("");}
}
SHTG A 7 
{
A_FireShotgun;
A_WeaponReady(WRF_NOPRIMARY|WRF_ALLOWRELOAD|WRF_ALLOWUSER#);
If(GetPlayerInput(INPUT_OLDBUTTONS)&BT_ATTACK&&GetPlayerInput(INPUT_BUTTONS)&BT_ALTATTACK)
{A_Overlay(2,"MissileShot");Return state("");}
Else{Return state("");}
}
SHTG BC 5

A_WeaponReady(WRF_NOPRIMARY|WRF_ALLOWRELOAD|WRF_ALLOWUSER#);
If(GetPlayerInput(INPUT_OLDBUTTONS)&BT_ATTACK&&GetPlayerInput(INPUT_BUTTONS)&BT_ALTATTACK)
{A_Overlay(2,"MissileShot");Return state("");}
Else{Return state("");}
}
SHTG D 4 
{

{A_Overlay(2,"MissileShot");Return state("");}
Else{Return state("");}
}
SHTG CB 5 
{
A_WeaponReady(WRF_NOPRIMARY|WRF_ALLOWRELOAD|WRF_ALLOWUSER#);
If(GetPlayerInput(INPUT_OLDBUTTONS)&BT_ATTACK&&GetPlayerInput(INPUT_BUTTONS)&BT_ALTATTACK)
{A_Overlay(2,"MissileShot");Return state("");}
Else{Return state("");}
}
SHTG A 3 
{
A_WeaponReady(WRF_NOPRIMARY|WRF_ALLOWRELOAD|WRF_ALLOWUSER#);
If(GetPlayerInput(INPUT_OLDBUTTONS)&BT_ATTACK&&GetPlayerInput(INPUT_BUTTONS)&BT_ALTATTACK)
{A_Overlay(2,"MissileShot");Return state("");}
Else{Return state("");}
}
SHTG A 7 A_ReFire
Goto Ready
	
AltFire:
Stop
	
MissileShot:
TNT1 A 8 A_GunFlash("Flash.MissileShot")
TNT1 A 0 A_TakeInventory("RocketAmmo",1)
TNT1 A 12 A_FireProjectile("Rocket",0,0)
Stop	

Flash.MissileShot:
TNT1 A 3 Bright A_Light1
TNT1 A 4 Bright
TNT1 AA 4 Bright A_Light2
Goto LightDone	
}
}

As variant instatnt attack can be called from CustomInventory item.

Code: Select all

Actor InvMissileShooter : CustomInventory
{
+INVENTORY.ALWAYSPICKUP
Inventory.MaxAmount 0
States
{
Spawn:
POSS A -1
Pickup:
TNT1 A 0 A_JumpIf(CountInv("RocketAmmo")<=0,3)
TNT1 A 0 A_TakeInventory("RocketAmmo",1)
TNT1 A 0 A_SpawnItemEx("Rocket",0,0,Height/2,cos(pitch)*20,0,-sin(pitch)*20,0,SXF_TRANSFERPITCH)
TNT1 A 0
Stop	
}
}

Btw, in a one of those threads you can also find a some useful related stuff for current task, I guess:

[Matt]

Can a player sprite be given to an actor that has no controlling player?

That require changing weapon code, while I need a way to do so without changing weapon code.

Can a player sprite be given to an actor that has no controlling player?

No, since psprite class nailed to playerinfo struct and you cant "deattach" it and/or create new psprite class/playerinfo struct.



Problem with weapon, that a_fireprojectile, and similar weapon functions, works only if player available. So I can change weapon state, when it lie on the ground, to "fire" and it play it states and animations, but dont actually shoot. And in inventory I cant call states of it without using it as reference to psprite.
So looks like this is impossible.

[Void Weaver]

That require changing weapon code, while I need a way to do so without changing weapon code.

It's quite significant detail. Anyway

As variant, instatnt attack can be called from CustomInventory item.

Give the similar item via ACS or, that's even better, write it on ACS entirely. This way doesn't bother about weapon or player actors altering.

[Matt]

Such possible in zscript without replacing actor.
I need a way, if it possible of course, to shoot from weapon directly from inventory. Like panic button to shoot from shotgun/pistol/etc without picking them up as weapon.

Do you mean something like:

1. I am holding BFG
2. I need to shoot pistol
3. I am still holding BFG but a pistol shot comes out of me

If so, is it acceptable to replace the pistol, or do you need a solution that uses the vanilla pistol actor?

[Apeirogon]

Second, vanilla BFG and vanilla pistol.

I ant to make it applicable to any weapon in general.

[Graf Zahl]

To make it short: All weapon actions directly access the PlayerInfo. Good luck trying to set it up so that it works without one. Some may just work without handling ammo consumption but others will just do nothing without a player.

[Apeirogon]

Not without playerinfo, without using weapon states as reference for psprite.
