[SOLVED] How to make custom tech tree?

[Maris]

I think it's possible... But how?

Currently there are 4 tech trees in DST: SCIENCE, MAGIC, ANCIENT and SHADOW. I'd like to add one (or few) custom tech tree for custom crafting structure. I thought it's easy but it's not. I hope that I missed something...

@Maris Hm, I'm looking for all the places where they put Maxwell's SHADOW tree when they added it, maybe you missed one of these?

• constants, TECH.NONE.NEWTREE = 0, also TECH.NEWTREE_ONE, etc (these are optional, but get used in the recipes a lot)
• components/builder:EvaluateTechTrees makes specific mention to each of the trees in order to bring in self.bonus. Looks like it might involve a messy override in order to add intrinsic character bonuses to a tree, because it does both the check and the result without any functions in between to hook into... You could maybe do it by replacing self.accessible_tech_trees with a proxy table that has a metatable so you can intercept the assignment? That's pretty gross, though.
• components/builder_replica has Setters and Getters for each tree's intrinsic bonuses, these are called later in recipepopup
• KnowsRecipe explicitly checks each tree in both builder and builder_replica
• components/prototyper constructor, self.trees.NEWTREE = 0, and have any prototyper prefabs you make increase that
• prefabs/player_classified OnTechTreesDirty checks each of them explicitly. You could add a listener for "techtreesdirty" and make your check there. Also inst.newtreelevel would need to be added.
• recipe, self.level.NEWTREE = self.level.NEWTREE or 0 needs to be added, could be done by overriding Recipe._ctor, or doing an AddClassPostConstruct (maybe? the recipe.lua file doesn't return the class though, so maybe not)
• tuning, PROTOTYPER_TREES needs to have each of its entries modified (although I think if you don't they should default to zero from the other changes)
• widgets/recipepopup GetHintTextForRecipe takes into account player intrinsic bonuses to trees for the help text. This looks like it might need to be overridden

It's actually pretty straightforward IIRC

local newtab = AddRecipeTab("Tab Name", *position on crafting menu (integer, 1 or more)*, "images/newtab.xml", "newtab.tex", *tag character must have in order to access the tab. Set to nil if you want everyone able to use it*)

Then when you add your recipes, reference 'newtab' for the tab.

E.g. AddRecipe("itemname", ingredients, newtab, etc)

@chromiumboy He's not adding a new recipe tab, he's adding a new tech tree. Like the way that there are items unlocked by various tiers of science, and items unlocked by various tiers of magic, etc.

Thanks a lot! I think i did it!

I made a lib for including in any mod. It's compatible to itself so the mods with the lib will be compatible to each other. 

How to use:

modimport "custom_tech_tree.lua"
AddNewTechTree("NEWTREE",2) --makes TECH.NEWTREE_ONE and TECH.NEWTREE_TWO

There was an error (crash on class.lua line 24), so I did it the other way. I'm not sure if it's really possible to make a proxy on tables in a component. Anyway thanks! I used your comment as a TODO list.

Oh, whoops, brain shortcircuited when I read references to Maxwells shadow magic XD Good to see that you guys seem to have sorted it out though

Thx, everything works perfect)

What I need change for the character don't learn the recipe after prototype, like Maxwell with the book (or ancient's crafts, etc)?

I want he can only craft around the custom tech machine

@edit I find, it is in recipe:

Recipe("name", {Ingredient("prefab", 2)}, RECIPETABS, TECH, nil, nil, true, nil, "tag")

Set true if the character can't learn the recipe.
