A blindning weapon

[Kzer-Za]

I want to give one weapon in Heretic an altfire with a blinding attack.

So I was wondering how to best go about it. From my limited knowledge of modding it seems that the way to go is to give this attack a FORCEPAIN flag and to give each monster a custom Pain state for this attack's type of damage and a Blind state in which this monster would A_Wander. Something like this:

Code: Select all

	Pain.BlindingWeapon:
		TNT1 A 0 A_SetUserVar("user_blindtimer", ACS_NamedExecuteWithResult("LevelTimer"))
		Goto Blind
	Blind:
		TNT1 A 0 A_JumpIfTargetInsideMeleeRange("BlindMelee") // I want the monster to fight if you bump into it
		SPRT ABCD x A_Wander
		TNT1 A 0 A_JumpIf((ACS_NamedExecuteWithResult("LevelTimer") - user_blindtimer) > 350, "See")
		Loop
	BlindMelee:
		// it would be a copy of Melee, except the ending:
		Goto Blind

Perhaps, I don't know a better way that someone could offer? What would be the drawbacks of this method?

You could simply have a variable like `sight_range` defined on your monster, when it's blinded, reduce it to some low value that is still enough for a melee attack, and make your `See` sequence use the parametrized version of `A_Look` that uses the `sight_range` variable for its `view range` argument and leave the rest unchanged. Don't forget to restore sight range after blind ends.

Thanks, I will try it when I know zscript better.

But it's not even ZScript really! It is actually feasible in Decorate.

Ah, you mean like this?

Code: Select all

IMPX ABCB 4 A_LookEx(0, 1, 50)

Or

Code: Select all

IMPX ABCB 4 A_LookEx(1, LOF_NOSIGHTCHECK)

But this works only until they don't actually go to their See state, I just tested it. And they do go to their See state if you attack them, even if you add LOF_NOSOUNDCHECK, LOF_DONTCHASEGOAL. And the intended purpose of the weapon was to temporarily allow attacking the blinded monster with impunity So if I understood you correctly, this doesn't seem to work as I intended.
