A new weapon spawn function

Ultimate Freedoomer · Post by **Ultimate Freedoomer** » Mon Sep 30, 2019 4:13 pm

Okay, I recently had an idea for a new weapon function: A_SetSpawnState. Basically, this would be a customizable version of A_selectPiece. The parameters would be as follows:

spawnstatenumber: this would determine what value to look for in order to carry out the jump
Statename: what state to jump to when the "state number" parameter equals the called value
Transfer sprite frame: situations where it'd be overlayed would use this. It'd be a boolean value.
Weapon.spawnlevel: this actor property is basically used by the 'spawnstatenumber" value of this function in much the same way A_SelectPiece uses the "health" property.

As an example, here's the a proposed recreation of the Vanilla Sigil using a_setSpawnState to recreate A_SelectPiece (thanks to the "modding the Sigil made easy" template for everything else):

Code: Select all

Actor NNSigil : weapon replaces Sigil
{
	Weapon.Kickback 100
	Weapon.SelectionOrder 4000
	+FLOORCLIP
	+WEAPON.CHEATNOTWEAPON
	+WEAPON.NOAUTOAIM
	Inventory.PickupSound "weapons/sigilcharge"
	Weapon.spawnlevel 1
	Tag "$TAG_SIGIL" // "SIGIL"
	Inventory.PickupMessage "$TXT_SIGIL" // "You picked up the SIGIL."
	States
	{
	Deselect:
		"----" A 1 Bright A_Lower(6)
		Loop
	Select:
		TNT1 A 1 Bright
		{
		If(CallACS("NNSigilPieceCount")==5)
		{
		a_overlay(2,"Viewlevel5");
		}
		If(CallACS("NNSigilPieceCount")==4)
		{
		a_overlay(2,"Viewlevel4");
		}
		If(CallACS("NNSigilPieceCount")==3)
		{
		a_overlay(2,"Viewlevel3");
		}
		If(CallACS("NNSigilPieceCount")==2)
		{
		a_overlay(2,"Viewlevel2");
		}
		If(CallACS("NNSigilPieceCount")==1)
		{
		a_overlay(2,"Viewlevel1");
		}
		A_Raise(6);
		}
		goto ready
	Viewlevel1:

What would this do that can't be done in a custom ZScript function?

EDIT: Or even just a few well-placed A_JumpIf* calls... I had to check the date on the OP to make sure this wasn't some kind of forum glitch and I was seeing a post from 5 years ago or something

This would help in situations where you’d want to make an upgradeable weapon without creating entirely new actors. The main issue is recreating the "health value to determine spawn state" setup.

This is a hack, nothing more. The answee is 'no'.

In what way is this a "Hack"?

Post by **Graf Zahl** » Tue Oct 01, 2019 1:48 am

In the way that it circumvents every established procedure to do such things.

Like I said: the main issue is that (as far as I know) no way of recreating the "health value spawn state" element of A_SelectPiece.

You'll have to do it yourself in ZScript. The engine development's' general direction these days is, DECORATE won't be extended anymore for specific-case function requests like this.

Do note that a ZScript function can be called from DECORATE.

Searching "health" in the OP and looking more closely I see what the intention is, and I think the answer to my original question is no (scroll down to the cyberdemons).
