Grr, I deliberately stripped Otiluke's Resilient Sphere of its secondary type 6 protection too....

[Roana]

The various monster summoning spells (MSI-VII, Animal Summoning I-III) all fail to penetrate immunity-to-spell-level defences. For instance, if you cast Monster Summoning I on someone protected by Minor Globe of Invulnerability, nothing happens.

 

I think there's a strong case for treating this as a bug. Reason being: it's trivial for players to circumvent it by casting the spell right next to the intended target rather than actually on it. It only matters for enemy AI scripting, and then only because

 

OnTheFloorButReallyReallyReallyCloseTo(NearestEnemyOf(Myself))

 

inexplicably got left out of the scripting language.

 

As far as I can see this is fixable just by increasing the Power of all summoning spells to 10 (that's what SCS does). Thoughts?

 

Hello,

 

why don't you solve scripting problems by scripting in another way ?

 

The BG games have mighty scripting abilities, but I guess, most of the modders learn WeiDu first...

 

Use this command and you get rid of your scripting probelm:

 

IF

 

See(NearestEnemyOfType([0.0.0.MAGE_ALL]))

See(NearestEnemyOfType([0.0.0.FIGHTER_ALL]))

HaveSpell(MONSTER_SUMMONING_3)

 

THEN

 

RESPONSE #100

 

Spell(LastSeenBy(Myself),MONSTER_SUMMONING_3)

 

END

 

As the Minor Globe of Invulnerability can only be cast on target "caster", a fighter will never have it (except there is - may be - one item somewhere in the game, that can cast it... - but this item has to be equipped and used just at the moment, the enemy cast his spell - chance is there, but it is a very little chance)

 

Just my two cents

 

Regards

I've no problems setting the power to zero to bypass these protections; I'm not in favor of changing the schools or types because I think these may have unforeseen ramifications.

 

@Nythrun

Please stop deleting posts; it made the thread completely incomprehensible. If code turns out to be incorrect or unnecessary, just edit your post to say so.

 

@Roana

For parties without fighters it means they won't cast the spell at all, which I consider a bigger bug than the original issue. Whatever target you choose to use there, it still wouldn't cast at a solo mage and would still fail on a Globed fighter-mage.

[devSin]

The target of the spell is irrelevant. Only the caster can break the summoning (although you script it on somebody, the engine still picks a ground target, and the effects are only checked against the caster).

[Nythrun]

There's a version difference between Windows BG2 and the Mac port then, because in WinBG2 casters' spell level immunity, secondary type immunity, and magic resistance never protect from their own spells. The caster is the only one who can't break summoning.

[devSin]

This is not the case when the effects from an external target are checked against the caster. It's the same reason things like some weapons fail MR when their impact effects affect the wielder.

[Nythrun]

Right, because the target type for summoning spells is area in the extended header and self for the actual effects, so the area is checked before target self has a chance to pass on its bypassing abilities via inheritance.

 

I think I'm talking past you again somehow, though, so I'll shut up.

[devSin]

I saw bypassing resistance and immunities mentioned elsewhere, so I wanted to clarify a bit: although it can be qualified that Target: Self effects bypass resistance, it omits the crucial part of the check -- the caster needs to be the target of the ability. Even dripping with resistance or immunities, you can still cast Magic Missile on yourself and feel the burn. In this case, it doesn't matter that the ability target and effect target is Preset Target, it matters that the effect to be applied is applied to the originator of the effect (caster == target).

 

Armor will bypass resistance because you cast it on yourself (and the effects affect the caster). If you cast Lightning Bolt or Burning Hands on Mrs. Berrybreath (before she gets swallowed by da bear!), since the target is not the same object as the caster, the effects won't bypass resistance, but you can cast them on yourself, and the effects will bypass resistance. Monster Summoning I will not bypass resistance because you can only choose a ground target (even if you click or script to cast on an actor, the engine will still pick only coordinates to target), in which case the originator of the Target: Self effects is not the caster (they're external effects and subject to normal resistance and immunity checks).

 

I haven't done anything with Baldur's Gate in a long time, but I suspect that there's no way any of these summoning spells will ever fail due to resistance and immunities on actors other than the caster (even if you click on Mencar Pebblecrusher, the game just treats it as if you'd clicked on the ground exactly at his current location). The only issue here is that any resistances or immunities that the caster has will block the effects from the summoning spells from being applied (causing the spell to fail).

For player casters, this is dead right. But it's not right (I'm fairly sure) for enemy AI scripts. They still target individuals, not the floor around them.

The behavior should be identical (even scripted to Spell(NearestEnemyOf(),SUMMON_THIS), the engine still picks a spot on the ground). But it's been a long time.
