A_JumpIfInTargetInventory problem

[OrinTheDoom]

I have a piece of code where a player is given or taken away Inventory item "Stl", depending on player's light level.

Code: Select all

script "LightCheck" enter
{
  while (true)
  {
    if (GetActorLightLevel(0) <= 96)
	{
		GiveInventory("Stl", 1);
	    SetActorProperty(0, APROP_RENDERSTYLE, STYLE_ADD);
	    print(f: CheckInventory("Stl")); //Gives 1.52...
	}
    else 
	{
	    TakeInventory("Stl", 1);
	    SetActorProperty(0, APROP_RENDERSTYLE, STYLE_NORMAL);
	    print(f: CheckInventory("Stl")); //Gives 0
	}
	delay(1);
  }
}
//Seems to work fine

However, when I use A_JumpIfInTargetInventory(), odd bug occurs.

Code: Select all

States
  {
  Spawn:
	POSS AB 0 A_GiveInventory("StKill", 1) //Not important in this case
	Goto Idle
  Idle:
	POSS AB 0 A_JumpIfInTargetInventory("Stl", 1, "DarkIdle")
	POSS AB 10 A_Look
	Loop
  DarkIdle:
	POSS AB 0 A_JumpIfInTargetInventory("Stl", 0, "Death")
	POSS AB 10 A_LookEx(0, 0, 192)
	Loop
  See:
	POSS AABBCCDD 0 A_TakeInventory("StKill", 1) //Also not important
	POSS AABBCCDD 0 A_JumpIfInTargetInventory("Stl", 1, "DarkSee")
	POSS AABBCCDD 3 A_Chase
	Loop
  DarkSee:
	POSS AABBCCDD 0 A_JumpIfInTargetInventory("Stl", 0, "See") //It automatically goes to "See" state, even though "Stl" = 1
	POSS AABBCCDD 3 A_Chase
	POSS AABBCCDD 0 A_JumpIfTargetInLOS("Search", 0, 0, 0, 768)
	Loop
  Search:
	POSS AABBCCDD 0 A_ClearTarget
	POSS AABBCCDD 0 A_JumpIfInTargetInventory("Stl", 1, "DarkSearch")
	POSS AABBCCDD 3 A_Wander
	POSS AB 10 A_Look
	Loop
  DarkSearch:
	POSS AABBCCDD 0 A_JumpIfInTargetInventory("Stl", 0, "Search")
	POSS AABBCCDD 3 A_Wander
	POSS AB 10 A_LookEx(0, 0, 192)
	Loop

When I alert the monster, it runs "See" state normally, but as soon as I enter the dark area (where is supposed to be "Stl" = 1 and jump to "DarkSee"), the "DarkSee" state automatically jumps back to "See" state, as if "Stl" = 0 and causes the game to overload and crash. I have figured that out by putting "Death" state instead of "See" state.
What could be the cause of the problem?

[wiki=A_JumpIfInventory]From the wiki[/wiki]:

Note that if amount is 0, the jump is only performed if the actor is carrying the maximum number of that item. This is useful for checking whether the player has the maximum amount of ammo for a particular weapon, regardless of whether or not he's found a backpack.

Well, seems like I've missed that one out XD thanks a lot!

Understandably, since that bit of info isn't included in the A_JumpIfInTargetInventory page.

UPDATE:
Meanwhile, i've figured out the problem; the part where it checks for amount - it doesn't check the exact amount (if you have 2, then you also have 1 of the item).

Code: Select all

script "LightCheck" enter
{
  GiveInventory("Stl", 1);
  while (true)
  {
    if (GetActorLightLevel(0) <= 96)
	{
		if (CheckInventory("Stl") < 2) GiveInventory("Stl", 1);
	    SetActorProperty(0, APROP_RENDERSTYLE, STYLE_ADD);
	    print(f: CheckInventory("Stl"));
	}
    else 
	{
		if (CheckInventory("Stl") > 1) TakeInventory("Stl", 1);
	    SetActorProperty(0, APROP_RENDERSTYLE, STYLE_NORMAL);
	    print(f: CheckInventory("Stl"));
	}
	delay(1);
  }
}

Code: Select all

ACTOR Stl : Inventory
{
  Inventory.MaxAmount 2
}

Code: Select all

  Spawn:
    POSS AB 0 A_GiveInventory("StKill", 1)
	Goto Idle
  Idle:
	POSS AB 0 A_JumpIfInTargetInventory("Stl", 2, "DarkIdle")
    POSS AB 10 A_Look
	Loop
  DarkIdle:
	POSS AB 0 A_JumpIfInTargetInventory("Stl", 1, "Idle")
    POSS AB 10 A_LookEx(0, 0, 192)
	Loop
  See:
    POSS AABBCCDD 0 A_TakeInventory("StKill", 1)
    POSS AABBCCDD 0 A_JumpIfInTargetInventory("Stl", 2, "DarkSee")
    POSS AABBCCDD 3 A_Chase
    Loop
  DarkSee:
    POSS AABBCCDD 0 A_JumpIfInTargetInventory("Stl", 1, "See")
    POSS AABBCCDD 3 A_Chase
	POSS AABBCCDD 0 A_JumpIfTargetInLOS("Search", 0, 0, 0, 768)
	Loop
  Search:
    POSS AABBCCDD 0 A_ClearTarget
    POSS AABBCCDD 0 A_JumpIfInTargetInventory("Stl", 2, "DarkSearch")
    POSS AABBCCDD 3 A_Wander
	POSS AB 10 A_Look
	Loop
  DarkSearch:
    POSS AABBCCDD 0 A_JumpIfInTargetInventory("Stl", 1, "Search")
    POSS AABBCCDD 3 A_Wander
	POSS AB 10 A_LookEx(0, 0, 192)
	Loop

and, unfortunately, still doing the same bug
