Description
-----------

The ``Engine`` class allows you to query and modify the game's run-time parameters, such as frames per second, time scale, and others.

Property Descriptions
---------------------

.. _class_Engine_editor_hint:

- :ref:`bool<class_bool>` **editor_hint**

+----------+------------------------+
| *Setter* | set_editor_hint(value) |
+----------+------------------------+
| *Getter* | is_editor_hint()       |
+----------+------------------------+

If ``true``, it is running inside the editor. Useful for tool scripts.

.. _class_Engine_iterations_per_second:

- :ref:`int<class_int>` **iterations_per_second**

+----------+----------------------------------+
| *Setter* | set_iterations_per_second(value) |
+----------+----------------------------------+
| *Getter* | get_iterations_per_second()      |
+----------+----------------------------------+

The number of fixed iterations per second (for fixed process and physics).

.. _class_Engine_physics_jitter_fix:

- :ref:`float<class_float>` **physics_jitter_fix**

+----------+-------------------------------+
| *Setter* | set_physics_jitter_fix(value) |
+----------+-------------------------------+
| *Getter* | get_physics_jitter_fix()      |
+----------+-------------------------------+

.. _class_Engine_target_fps:

- :ref:`int<class_int>` **target_fps**

+----------+-----------------------+
| *Setter* | set_target_fps(value) |
+----------+-----------------------+
| *Getter* | get_target_fps()      |
+----------+-----------------------+

The desired frames per second. If the hardware cannot keep up, this setting may not be respected. Defaults to 0, which indicates no limit.

.. _class_Engine_time_scale:

- :ref:`float<class_float>` **time_scale**

+----------+-----------------------+
| *Setter* | set_time_scale(value) |
+----------+-----------------------+
| *Getter* | get_time_scale()      |
+----------+-----------------------+

Controls how fast or slow the in-game clock ticks versus the real life one. It defaults to 1.0. A value of 2.0 means the game moves twice as fast as real life, whilst a value of 0.5 means the game moves at half the regular speed.

Method Descriptions
-------------------

.. _class_Engine_get_author_info:

- :ref:`Dictionary<class_Dictionary>` **get_author_info** **(** **)** const

"major"    - Holds the major version number as an int

"minor"    - Holds the minor version number as an int

"patch"    - Holds the patch version number as an int

"status"   - Holds the status (e.g. "beta", "rc1", "rc2", ... "stable") as a String

"build"    - Holds the build name (e.g. "custom-build") as a String

"string"   - major + minor + patch + status + build in a single String

.. _class_Engine_has_singleton:

.. _class_Engine_is_in_physics_frame:

- :ref:`bool<class_bool>` **is_in_physics_frame** **(** **)** const

Returns ``true`` if the game is inside the fixed process and physics phase of the game loop.
