(help) Custom TAB or RECIPE avaliable only during the night

[Joy Machs]

Hello everyone.

After fight a lot to start to understand how to MOD things in DST, I reached a point where I wasn't able to fix by myself.

My character is a star gazer and he can craft a custom item called "star chart" who work similar to item "map scroll". This item is always available in "Cartography" tab since you have the ingredients to craft it. So the issue is:
 

Since he is only able to create "star charts" when he can see the stars, he only could make this item during the night phase of the game and in the "forest world". Not inside "caves".

So, there is a way to make the recipe be available to craft only during the night phase? And the is a way to add a speech like "I can't draw what I can't see" when the character tries to create this item during  the day, dusk or in the caves?
 

Here is what my star_chart.lua looks like now (it's a bit dirty >_<):

Thanks since now! =)

I've got an idea what you could try doing.
 

local tinkeringtab = AddRecipeTab("Tinkering", 10, "images/tinkering_tab.xml", "tinkering_tab.tex", "tinkeringtab")

local wagstaffnormalgoggles_recipe = AddRecipe("wagstaffnormalgoggles", {Ingredient("goldnugget", 1), Ingredient("pigskin", 1)}, tinkeringtab, TECH.NONE, nil, nil, nil, nil)

You need to create a new crafting tab similar to how I did, and the last bit of it "tinkeringtab" is the tag needed to access that tab, So only characters with the tinkeringtab tag can access  it, So what you could do is watch the world states using inst:WatchWorldState I believe, and once it becomes night you add the tag, and once night is over you remove the tag. Thus removing access to the recipe during day and dusk but letting you accces it during night.

[eternalLocket]

If I understand correctly, the mandrake checks if it's daytime to decide if it should kill the mandrake or make it run around. Could probably use that as well to decide whether the tab becomes unlocked or not, depending on the time of day.

[Joy Machs]

Thanks for your suggestions, I was able to make some progress. Here we go:

My character LUA  has a local function to determinate his speed depending the time of the day: day/dusk/night:
 

-- Speed values
local day_speed = 0.9
local dusk_speed = 1
local night_speed = 1.2

local function onphase(inst, phase)
	local speed = 1
	
	if phase == "day" then speed = day_speed
	elseif phase == "dusk" then speed = dusk_speed
	else speed = night_speed
	end
	
	inst.components.locomotor:SetExternalSpeedMultiplier( inst, "Acceleration", speed )

end

 

So I thought I could use the same function, but now using tags. I changed the tag of the star chart recipe to "chartman" and write this local function using it:
 

--cartographer
local function onphase(inst, phase)

    if phase == "night" then inst:AddTag("chartman")
    elseif TheWorld.worldprefab == "cave" then inst:RemoveTag("chartman")
    else inst:RemoveTag("chartman")
    end

 

The result was great! No crashes and when my character spawned in the world, the "Cartography" tab wasn't there. When the night came, as I made the first item to create the star chart, the "cartography tab" appear, making the recipe available. (images below)

Spoiler

But now I hit my face in another issue:

Case 1 - IF I don't craft the item, when the day comes, the cartography tab disappear in the moment I move any item in my inventory.

Case 2 - IF I craft the item, when the day comes, the cartography tab stay there and the recipe disappear. (image below)

Spoiler

In Case 1, as I could see, it seems like the local function only actives the cartography tab when I move some item in my inventory in any sense (moving any item to another space, craft something, picking something...) and the same happens when the day comes. The cartography tab only disappear when I move some item.

In Case 2, my intention is to make the cartography tab disappear, similar to when we get away from the Cartographer Desk. I don't know if has to do with "learn" the recipe and I need to forget it to make the tab disappear of if the is a way to make the tab hide even with the recipe learned.

My gosh... I'm becoming bald with all this issues. XD

EDIT: Just in case someone wants to try my mod, I made it available in workshop. Here goes the link:

post a link of my mod

[eternalLocket]

I am new to lua and modding, so I wouldn't know the code to make it work. But in your first case, it sounds like what you need is for the tab to be unlocked by default. So that it's not reliant on whether you have the crafting materials needed to make anything. While also keeping it linked to the time of day. So all I can really suggest is also looking at what makes the regular tabs unlocked by default. Then try to find a way to link that to the time of day.

As for your second case, I suggest looking at the code for the Ancient Pseudoscience Station. Since crafted items from it are not remembered; in case you want to go that route. I have no idea if it would be possible to simply hide the tab though, probably is.

I imagine the reason the recipe is disappearing is because the night time requirement is linked to it. But not linked to the tab disappearing. So either find a way to make the tab disappear too. Or keep the recipe from being remembered.

So, based on this hint, I could make a small progress. Thanks!

First, I searched for the altar_prototyper.lua, but then I thought: "he said the crafted itens aren't remembered"... So I decided to search the recipes of the Ancient Tab. A thing ancient recipes had in common is a "unlock = true" in their recipes scripts. So I did the same with my star char:

----------
local star_chart_recipe =
AddRecipe("star_chart", {Ingredient("fav_pencil", 1, "images/inventoryimages/fav_pencil.xml"), Ingredient("waxpaper", 1)}, GLOBAL.RECIPETABS.CARTOGRAPHY,
GLOBAL.TECH.CARTPGRAPHY_ONE,
nil,
nil,
true, (this nil was related to the item be remembered(I don't know if I can use this term) or not.)
nil,
"chartman",
"images/inventoryimages/star_chart.xml")
----------

Now, the only thing I need is to make the cartography tab appear automatically when the night falls and disappear when the sun rises.

Yes. I took a look in the science machine and cartographer desk to try to understand how they become available through "proximity", but I couldn't realize how to do it relating with the world time.

A workaround would be: make the function inspect the inventory (something like read the itens or refresh the inventory) when the night falls and inspect again when the sun rises... but I don't know if it would work and how I can do it.

Just like people told you above. Make a periodic task with inst:DoPeriodicTask() and check TheWorld.state.isday 

Add tag "hide", check If night and has tag "hide" then remove tag "hide" add tag "show" and put your code, otherwise (not night and has tag "show") remove tag "show" and add tag "hide". And then start periodic task with that function. Something like that...

Probably you don't need to inspect your inventory. If you aren't sure how to try to look for game's scripts.

I'm afraid I'm not able to script your idea. I can understand what you said, but I wouldn't know how to put it to work or how to write the lines. My knowledge about LUA was obtained searching others mods and its very poor to be honest.

I confess I looked in others prefrabs like "pigman", "fireflies", "glommer_flower" and other one who has something related with "time" and "night phase", but I wasn't able to recognize any line who could help me out.

Right now, everything I tested leads me to the same result: The cartography tab only appear it I interact with a item in my inventory. The same happens when it has to disappear. It's the last thing I have to do to make my mod complete and that's why I'm asking for help! XD

I'm very grateful for the tips so far, but seems like I can't break this wall alone. =/

[thezotikrus]

This is not mine idea, I saw it somewhere. I believe it should look like that

Spoiler

inst:AddTag("hide")
local function CheckDayTime(inst)
	if TheWorld.state.isnight and inst:HasTag("hide")
		--SHOW YOUR CARTOGRATHY TAB SOMEHOW
		inst:RemoveTag("hide")
		inst:AddTag("show")
	end
	
	if TheWorld.state.isday and inst:HasTag("show")
		--HIDE YOUR CARTOGRATHY TAB SOMEHOW
		inst:RemoveTag("show")
		inst:AddTag("hide")
	end
end

inst:DoPeriodicTask(0.0, function(inst) CheckDayTime(inst) end)

 

So it should constantly check day state and hide or show your tab. You only need to put your part from altar prototyper or something like that.

[Ultroman]

Why not listen for the worldstate change events? You can set up a listener to listen for when it changes to day, to dusk, to night, even the moonphases etc.
