How can I programmatically enable fullscreen mode for my PC game using Godot?

Enabling Fullscreen Mode in Godot

To programmatically enable fullscreen mode in a PC game developed with Godot, you can utilize the engine’s scripting capabilities to adjust window display settings. Below are the steps and script snippets to achieve fullscreen functionality:

Using GDScript

func _ready():
    # Set the game window to fullscreen mode
    OS.window_fullscreen = true

This simple script can be attached to a node within your scene. When the scene loads (_ready() function), it sets the game window to fullscreen.

Say goodbye to boredom — play games!

Toggle Fullscreen Dynamically

To allow players to toggle between fullscreen and windowed mode, you can implement a function bound to an input action, such as a key press:

func toggle_fullscreen():
    OS.window_fullscreen = !OS.window_fullscreen

Bind this function to a key in the project settings under Input Map, and call toggle_fullscreen() when the key is pressed.

Adjusting Screen Resolution

Fullscreen applications often need specific resolutions. Use the following command to set a specific resolution:

OS.set_window_size(Vector2(1920, 1080))

This will ensure that when in fullscreen, the game maintains a 1920×1080 resolution.

Considerations

• Aspect Ratio: Make sure your game’s visuals adhere to a consistent aspect ratio. Use anchors, containers, or code to adjust the UI dynamically.
• Performance: Test your game’s performance across different resolutions as the changes might affect rendering.
• Context Restoration: Switching between window modes can sometimes lead to resource reallocation in graphics. Ensure that textures and shaders respond dynamically to such changes.

By following these steps, you can effectively manage and implement fullscreen mode within your Godot projects, offering players a seamless experience across different screen configurations.
