Pausing the game

Many games require some sort of pause mode to allow the player to take a break from the action. In Godot, pausing is a function of the SceneTree and can be set using its paused property. When the SceneTree is paused, three things happen:

• The physics thread stops running
• _process() and _physics_process() are no longer called on any nodes
• The _input() and _input_event() methods are also not called for inputs

When pause mode is triggered, every node in the running game reacts accordingly, based on how you’ve configured it. This behavior is set via the node’s Process/Mode property, which you’ll find near the bottom of the Inspector list.

The pause mode can be set to the following values:

• Inherit – The node uses the same mode as its parent
• Pausable – The node pauses when the scene tree is paused
• When Paused – The node only runs when the tree is paused
• Always – The node always...
