[LE] Script IF Statement help

[gitsas]

For some reason this script runs BOTH If statements??

Scriptname AAAGiveSpells extends activemagiceffect  

SPELL Property HolyLight  Auto
BOOL  Property HolyLightKnown = False Auto


Event OnEffectStart(Actor akTarget, Actor akCaster)

Actor Player = Game.GetPlayer()
INT PlayerLevel = Player.GetLevel()

;HOLY LIGHT

If PlayerLevel >= 1 && HolyLightKnown == false
	Player.addspell(HolyLight)
	Debug.Messagebox("Holy Light Added")
        HolyLightKnown = true
EndIf


If PlayerLevel >= 1 && HolyLightKnown == true
	Debug.Messagebox("You already know this spell.")
EndIf



EndEvent

Yep. Because the spell is added in the first loop, so the second loop is always going to be true.

[IsharaMeradin]

Multiple ways to fix this.

Examples:

 

Use an ElseIf so that if the first fails it tries the second

If PlayerLevel >= 1 && HolyLightKnown == false
	Player.addspell(HolyLight)
	Debug.Messagebox("Holy Light Added")
        HolyLightKnown = true
ElseIf PlayerLevel >= 1 && HolyLightKnown == true
	Debug.Messagebox("You already know this spell.")
EndIf

Reverse the order so that it checks for a true bool when it should be false - but both conditions will be checked every time thus a small but wasted amount of processing time

If PlayerLevel >= 1 && HolyLightKnown == true
	Debug.Messagebox("You already know this spell.")
EndIf
If PlayerLevel >= 1 && HolyLightKnown == false
	Player.addspell(HolyLight)
	Debug.Messagebox("Holy Light Added")
        HolyLightKnown = true
EndIf

Check once for player level, then check the bool and use an Else statement to process one if true and the other if false

If PlayerLevel >= 1 
	If HolyLightKnown == false
		Player.addspell(HolyLight)
		Debug.Messagebox("Holy Light Added")
        	HolyLightKnown = true
	Else
		Debug.Messagebox("You already know this spell.")
	EndIf
EndIf

Thank you so much! it works!

 

I also tried to add an animation:

elseif Player.HasSpell(HolyLight) && PlayerLevel >= 1
	Game.ForceThirdPerson()
	Debug.SendAnimationEvent(Player, "IdlePray")
	Utility.Wait(4.0)
	Debug.Messagebox("You now know Holy Light.")

Everything works great, but the animation never stops.

Do you by any chance know how I can stop it?

 

I tried:

Debug.SendAnimationEvent(Player, "ActionIdleStop")

But it doesn't work.

 

Thanks again for the help!!

Figured it out its: debug.SendAnimationEvent(Player,"IdleForceDefaultState")

[NexusComa2]

;------------------------------------ why it didn't work

If PlayerLevel >= 1 && HolyLightKnown == false ; they don't have the spell and are over level 0

Player.addspell(HolyLight) ; spell added

Debug.Messagebox("Holy Light Added") ; added announced

HolyLightKnown = true ; flag set to true

EndIf

; at this point in the script they now have the spell and the flag is set to true so the next if statement will fire too

If PlayerLevel >= 1 && HolyLightKnown == true ; they do have the spell and are over level 0

Debug.Messagebox("You already know this spell.") ; known announced

EndIf

;------------------------------------ fix (one of many ways)

 

If HolyLightKnown == true ;most unlikely checked 1st

Debug.Messagebox("You already know this spell.")

Elseif PlayerLevel >= 1 ; fix with a double meaning (no need for the &&) elseif statement

Player.addspell(HolyLight)

Debug.Messagebox("Holy Light Added")

HolyLightKnown = true

EndIf

I also find the >= level 1 suspect ... is it possible to be a level 0 ?

Not possible to be level 0. The player always starts out at level 1.

[NexusComa2]

I didn't think so and would make that part of the script redundant. So ...

 

if HolyLightKnown == true ;most unlikely checked 1st

Debug.Messagebox("You already know this spell.")

Else ;simple else statement

Player.addspell(HolyLight)

Debug.Messagebox("Holy Light Added")

HolyLightKnown = true

EndIf

[IsharaMeradin]

Unless they are testing the script to ensure that it behaves properly before adding in the correct level requirement. In which case, the level check would still need to be present.

[NexusComa2]

True. The only real issue was "syntax logic". The "old true/false", if statement logic error in with the syntax. Just looking for a way to slip in how an else statement would be used ...

The combinations of: if, else, elseif and endif can be used to ask any question or direct program flow and logic. Well worth the time to really dig into how the combinations can be used (along with, used with flags).

I just looked at your [ Spoiler ] ... I see you did cover that ...
