pyunity.files module

Source code: pyunity/files.py

---

Module to load files and scripts. Also manages project structure.

pyunity.files.convert(type, list)

Converts a Python array to a C type from ctypes.

Parameters:

• type (_ctypes.PyCSimpleType) – Type to cast to.

• list (list) – List to cast

Returns:

A C array

Return type:

object

class pyunity.files.Behaviour

Bases: Component

Base class for behaviours that can be scripted.

Awake()

Called every time a scene is loaded up, regardless whether the Behaviour is enabled or not. Cannot be an async function.

async Start()

Called every time a scene is loaded up. Only called when the Behaviour is enabled. Can be either a normal function or an async function.

async Update(dt)

Called every frame. Can be either a normal function or an async function.

Parameters:

dt (float) – Time since last frame, sent by the scene that the Behaviour is in.

async FixedUpdate(dt)

Called every frame, in each physics step. Can be either a normal function or an async function.

Parameters:

dt (float) – Length of this physics step

async LateUpdate(dt)

Called every frame, after physics processing. Can be either a normal function or an async function.

Parameters:

dt (float) – Time since last frame, sent by the scene that the Behaviour is in.

async OnPreRender()

Called before rendering happens. Can be either a normal function or an async function.

async OnPostRender()

Called after rendering happens. Can be either a normal function or an async function.

OnDestroy()

Called at the end of each Scene. Cannot be an async function.

class pyunity.files.Scripts

Bases: object

Utility class for loading scripts in a folder.

template = 'from pyunity import *\n\nclass {}(Behaviour):\n    async def Start(self):\n        pass\n\n    async def Update(self, dt):\n        pass\n'

Type:    str

var = {}

Type:    dict

static CheckScript(text)

Check if text is a valid script for PyUnity.

Parameters:

text (list) – List of lines

Returns:

If script is valid or not.

Return type:

bool

Notes

This function checks each line to see if it matches at least one of these criteria:

1. The line is an import statement

2. The line is just whitespace or blank

3. The line is just a comment preceded by whitespace or nothing

4. The line is a class definition

5. The line has an indentation at the beginning

These checks are essential to ensure no malicious code is run to break the PyUnity engine.

static GenerateModule()

static LoadScript(path, force=False)

Loads a PyUnity script by path.

Parameters:

• path (Pathlike) – A path to a PyUnity script

• force (bool) – Continue on error

Returns:

The compiled PyUnity script

Return type:

type

Notes

This function will add a module to sys.modules that is called PyUnityScripts, and can be imported like any other module. The module will also have a variable called __pyunity__ which shows that it is from PyUnity and not a real module. If an existing module named PyUnityScripts is present and does not have the __pyunity__ variable set, then a warning will be issued and it will be replaced.

class pyunity.files.Prefab

Bases: Asset

Prefab model

Contains(obj)

Instantiate(scene=None, parent=None, position=Vector3(0, 0, 0), rotation=Quaternion(1, 0, 0, 0), scale=Vector3(1, 1, 1), worldSpace=False)

Instantiate this prefab.

Parameters:

• scene (Scene, optional) – The scene to instantiate in. If None, the current scene is selected.

• parent (GameObject, optional) – The parent to instantiate the Prefab under. If None, the prefab will be instantiated at the root of the scene.

• position (Vector3, optional) – Position of the newly created GameObject, by default Vector3.zero()

• rotation (Quaternion, optional) – Rotation of the newly created GameObject, by default Quaternion.identity()

• scale (Vector3, optional) – Scale of the newly created GameObject, by default Vector3.one()

• worldSpace (bool, optional) – Whether the above 3 properties are world space or local space, by default False

Returns:

The newly created GameObject

Return type:

GameObject

Raises:

PyUnityException – If scene is None but no scene is running
