Checking content in hands + Spell light is active [Solved]

[Jouki]

Hello, can you someone help me how can I get information if the party holds the torch in hand? I would like to create codnition if there's (or not) a light in room do something

Jouki, I think the torchEquipped() script below should do the trick.

It checks all the champions with an item in their hand with the "TorchItemComponent", which should for all torches.
However, there might be other items with lightsources that don't have this component. This script does not check for those.

Code: Select all

function torchEquipped()
	local hasTorch = false
	for i = 1,4 do
		local c = party.party:getChampionByOrdinal(i)
		hasTorch = hasTorch or checkSlotForTorch(c, 1) or checkSlotForTorch(c, 2)
	end
	return hasTorch
end

function checkSlotForTorch(champion, slot)
	local torchInSlot = false
	local j = champion:getItem(slot)
	if j then
		torchInSlot = (j.go:getComponent("torchitem") ~= nil)
	end	
	return torchInSlot
end

	local j = champion:getItem(slot)
	if j then
		torchInSlot = (j.go:getComponent("torchitem") ~= nil)
	end	
	return torchInSlot
end

this line sends error

local j = champion:getItem(slot)

"getItem a nil value", I have no idea why is it doing, it looks everything is right...

..."getItem a nil value", I have no idea why is it doing, it looks everything is right...

*I was wrong... I get a different error...

Ah... This happened when I called the wrong function.

Try this:
Temporarily add this to the script and call it with a button.

Code: Select all

function check()
	print(torchEquipped())
end

It should [when the button is pressed] print true or false ~whether anyone has a torch equipped. It's a neat script.

You have probably linked both functions to the same floor trigger. The torchEquipped function calls on the checkSlotForTorch function (which doesn't need to be connected up). Because you've linked the second function it's running twice, but in the second instance it doesn't know what item in what slot it's supposed to be looking for (the torch called by the first function).

oh god, idk if I was calling wrong function, nevermind it works (printing true/false) btw could you write script checking if the spell "light" is actived, please? ^^

btw could you write script checking if the spell "light" is actived, please? ^^

I don't know if that's possible; it was not [really] possible in LoG1.

Code: Select all

-- Returns true if the Light spell is activated.
function lightSpellOn()
  -- no light source: 0.1, 0.13, 0.25
  -- torch: 1.2, 0.8, 0.6
  -- light spell: 0.56, 0.75, 1.2
  -- both: 1.76, 1.55, 1.8
  return party.torch:getColor()[3] > 1.19
end

This is new...
Worked out from the light components in the asset pack definitions? Very neat.

wow, thanks. It's much easier way to figure out.
