I have an item that creates light when in the characters hand(like a torch) and everything works fine except it always lights brightest to the north, and the ground to the south is completely dark so you can barely even see the floor. I tried using light_component:setDirection(vec(3)) but it didn't change anything. I probably have to change the offset or something but there is no
function to do that in the scripting reference.
light definition:

Code: Select all

			onEquipItem = function(self, champion, slot)
--				print("onEquipItem")
				if (slot == ItemSlot.Weapon) then
--					print("on")
					local light_component = party:createComponent("Light", "light")
					light_component:setBrightness(0.2)
					light_component:setColor (vec(64, 40, 18))
					light_component:setRange(6)
					light_component:setDirection(vec(3))
				end
			end,
			onUnequipItem = function(self, champion, slot)
--				print("onUnequipItem")
				if (slot == ItemSlot.Weapon) then
--					print("off")
					party:removeComponent("light")
				end
			end,

Yes there is. Component:setOffset() is in both the official scripting reference and the wiki one:
http://www.grimrock.net/modding/scripti ... #Component
https://github.com/JKos/log2doc/wiki/Co ... #component

LightComponent:setDirection() is only meaningful for directional lights, which your light is not (the default light type is point).

I'm back to my candle item.

I'd suggest adding a TimerComponent to the party on the fly instead of spawning a new object, so that you don't have the issue of the timer slowing down if the party leaves the map.

I have tried this but if I don't oversee anything there is no way to give a component a name by a function. So I am not able to adress it here and to set its stats.

Seems I have to get back to my external timer object and live with the fact, that it will run slower when the party is on another level. Or I script something that copies that timer always on the party.level.

You can provide a second argument to createComponent() to name the new component. For example:

Code: Select all

party:createComponent("Timer","fish")

Really? Good to know.

Too sad that it's not documented anywhere...

Has anyone recreated the "testament" object that the island master drops when killed in the Trickster's Lair?

Has anyone recreated the "testament" object that the island master drops when killed in the Trickster's Lair?

There's nothing special about this object, it's defined in nex_assets.lua in the asset pack:

Code: Select all

defineObject{
	name = "testament",
	baseObject = "base_item",
	components = {
		{
			class = "Model",
			model = "assets/models/items/waxseal_note.fbx",
		},
		{
			class = "Item",
			uiName = "Testament",
			gfxIndex = 235,
			weight = 0.1,
			traits = { "readable" },
		},
		{
			class = "UsableItem",
			onUseItem = function(self)
				GameMode.showImage("assets/textures/gui/scroll_images/testament.tga")
				return false
			end,
		},
	},
}

I actually never noticed this file o,o

Well, well, it's me again - still working on that candle item.

What I have so far is this in the onEquipItem function:

Code: Select all

					local tim = self.go.id
					if not party.tim then 
						party:createComponent("Timer", "tim") 		
						party.tim:setTimerInterval(5) 
						party.tim:disable()
						party.tim:addConnector("onActivate", "find_item" , "destr", self.go.id) 
					end
					party.tim:start()

This works so far, means: the component gets created, gets programmed and triggers this function in an external script entity:

Code: Select all

			function destr(item)
				delayedCall(self.go.id,0.01,"destr2", item)
			end
			function destr2(item)
				find_item.script.findAnywhere(item,party.level,true)
				hudPrint("The candle has burned to the end.")
				party:removeComponent(item)
			end

What doesn't work that I get the name of the item (which is the same as the created component's name) handled over to the external function. I know that a fourth value is not reported for addConnector("onActivate", "find_item" , "destr", self.go.id) - but I hoped that it works. Doesn't seem so. So I do not know how to tell the other function (minmay's findAnywhere) which item is meant to be destroyed.

Anyone an idea how to do that?

Use the candle's id (or another string containing it, if you prefer) as the name of your TimerComponent. You can then retrieve it with Component:getName(). Like this:

Code: Select all

local timerName = self.go.id
if not party:getComponent(timerName) then
	local timer = party:createComponent("Timer",timerName)
	timer:setTimerInterval(5)
	timer:addConnector("onActivate", "find_item", "destr")
end
party:getComponent(timerName):start()

Code: Select all

function destr(timer)
	local itemId = timer:getName()
	find_item.script.findAnywhere(itemId,party.level,true)
	hudPrint("The candle has burned to the end.")
	timer.go:removeComponent(timer:getName())
end

Remember to pause the timer in your onUnequipItem hook as well.
