How can I implement a feature that allows players to toggle full screen mode in my game’s settings using Defold?

Implementing Full Screen Toggle in Defold

To implement a feature that allows players to toggle full screen mode in Defold, follow these detailed steps:

1. Accessing Game Settings

Begin by accessing the game’s settings module. Defold uses scripts for handling changes in configuration. Ensure you have a dedicated script that manages user settings related to the display, including screen mode.

2. Scripting the Full Screen Toggle

-- Defold script to toggle full screen mode
local function toggle_fullscreen(self)
    local current_mode = sys.get_config("display.fullscreen", "0")
    if current_mode == "1" then
        sys.set_config("display.fullscreen", "0")
    else
        sys.set_config("display.fullscreen", "1")
    end
    restart_game() -- Necessary to apply changes
end

This script snippet checks the current full screen status using sys.get_config and toggles it. Note that changes take effect after a restart which can be triggered by restart_game().

3. Integrating with UI

Integrate the script with a button in your game’s settings menu. Use Defold’s GUI scripts to handle button clicks and call toggle_fullscreen when the player chooses to switch modes.

function on_message(self, message_id, message, sender)
    if message_id == hash("toggle_fullscreen") then
        toggle_fullscreen(self)
    end
end

4. UI/UX Considerations

Ensure that your game provides visual feedback or a confirmation dialogue when the screen mode is toggled. This enhances the player experience and confirms the action was successful.

5. Testing and Optimization

• Test the toggling functionality across different platforms to ensure consistency.
• Optimize transition times between windowed and full screen to prevent potential lag or screen flickering.

Properly implementing this feature can significantly enhance player experience by allowing flexible display options tailored to player preferences.
