FAQ

Frequently asked questions:

• Q: Why is the map black when loading for the first time?

  • A. You must obtain a free API key from either (or both) MapTiler which currently does not require a credit/debit card, or Mapbox which does require a credit/debit card, but as of writing, you will receive 200K free requests per month, which should be sufficient for an individual user.

• Q: Why is it that when I change my grid width/height settings, nothing happens after hitting apply?

  • A. You must restart Supercell Wx in order to apply these changes. Each version reduces the number of settings requiring a restart.

• Q: How can I contribute?

  • A. Head to Developer Setup and Contributing to configure the Supercell Wx development environment for your IDE. Currently Visual Studio and Visual Studio Code are recommended, with other IDEs remaining untested at this time.
