Basic Modding Examples

From Vintage Story Wiki
Jump to: navigation, search

A large amount of game content is freely modifiable through editing text files. If you feel like tinkering around, just open your assets folder. To locate it under windows, hit Winkey+R in Windows then paste in this line %appdata%/Vintagestory/assets and hit enter.

Starting from Version 1.6 you should enable the error reporter by running the chat command /errorreporter 1 when you modify json files. With this, if you made any mistakes while changing the asset files, the game will display a dialog showing you all the errors it found.

In earlier versions of the game you need to manually check out the log files in %appdata%/VintageStoryData/Logs/server-main.txt and client-main.txt

Changing sleep duration in beds

Beds in the Vanilla game are pretty limited, as they let you only sleep 3-5.5 hours every night. More often than not players prefer to skip the whole night. To achieve that open the file assets/blocktypes/wood/generic/bed.json

Line 7-11 should contain these lines:

	attributesByType: {
		"bed-wood-*": { sleepEfficiency: 0.375 },
		"bed-hay-*": { sleepEfficiency: 0.25  },
		"bed-woodaged-*": { sleepEfficiency: 0.45833  }

The sleepEfficiency attribute is specific to the bed. In this case a value of 1 means the player can sleep half the day. The hay bed has a value of 0.25, which means the player can sleep for 12 * 0.25 = 3 in-game hours. Change the value to anything between 0...1 and start the game or leave and re-enter your singleplayer world. Next time you sleep in the bed you will be skipping that amount of time.

Making wolves less dangerous

Our favorite arch enemy the wolf. If you don't like the silent horror of the winterlands, we can tame him with a few tweaks ;-) Open the file assets/entities/land/wolf-male.json

Line 47-60 should contain this:

	code: "meleeattack",
	entityCodes: ["player"],
	priority: 2,
	damage: 10.01,
	slot: 1,
	mincooldown: 1500, 
	maxcooldown: 1500, 
	attackDurationMs: 800,
	damagePlayerAtMs: 500,
	animation: "Attack",
	animationSpeed: 2.5,
	sound: "creature/wolf/wolf-attack"

This is the configuration for the wolves ai task to induce damage to very close by enemies. By default the wolf damages you by 10.01 health points, which means any unprotected player dies in 2 attacks. If you were to change it to 5, the wolf has to attack you up to 4 times before a fully healed player dies.

Right below is the enemy seeking task

	code: "seekentity",
	entityCodes: ["player"],
	priority: 1.5,
	movespeed: 0.022,
	seekingRange: 20,
	animation: "Run",
	animationSpeed: 1.5,
	sound: "creature/wolf/wolf-growl"

You can perhaps read out that the wolf has a seeking range of 20 blocks. This means if the wolf finds a player within a radius of 20 blocks, it will start walking towards that player. Changing that to something lower, like 5 blocks, means you can get much closer to a wolf before he begins to chase you.

Be sure to also apply the changes to the female wolf in wolf-female.json!

Playing around with world generation

Inside the assets folder, navigate to worldgen/terrain/standard. Copy aside the landforms.json so you have a backup, then open the landforms.json. Remove everything in this file and paste in the following text:

	code: "landforms",
			"code":  "humongous mountain",
			"comment": "humongous mountains with caverns in them",
			"hexcolor": "#5BC184",
			"weight": 2,
			"useClimateMap": false,
			"terrainOctaves":          [0, 0, 0, 0, 1,   1, 1, 1, 0.6, 0.2],
			"terrainOctaveThresholds": [0, 0, 0, 0, 0.5, 0, 0,   0,   0, 0],
			"terrainYKeyPositions":    [0,  0.33, 0.37, 0.42, 0.43, 0.5, 0.6, 0.7, 0.9, 0.97, 1],
			"terrainYKeyThresholds":   [1,    1, 0.87, 0.84, 0.7, 0.94, 1, 1, 0.1, 0.05, 0]

Now next time you create a new survival world, the entire world is made of humongous mountains. Congratulations, you can now officially call yourself a modder!

Very shortly explained, this file defines the list of land forms that may appear in the world. Each section enclosed in { ... } is one landform. If you feel like, you can play around with the values for terrainYKeyPositions and terrainYKeyThresholds and see what happens (they have to be values between 0 and 1). These numbers basically determine the shape of the landform at certain elevations.

More info on on that is available on the World Generation page.

Playing around with blocks

You can tweak, add or remove almost any block you want, inluding their shape. Inside the assets folder: - The blocks themselves are all in the subfolder blocktypes - The block textures in textures/blocks - The shapes of the blocks are in blockshapes/ - these you can open up with our custom model creator

Some examples what you can do: Let's make the fire pit emit a red light and huge particles
