Restore Mapper

Adds the unused Mapper item to the store.

All players in the lobby must install.

Default functionality remains more or less identical to vanilla, but with some fixes:

• Mapper always follows the player holding the device, instead of who is selected on the ship radar
• Multiple mappers can display different things on their screens
• Mapper now plays a short animation when updating the screen for additional feedback

Some added perks:

• Mapper can see inside of caverns, where the ship radar would normally display a "No signal!" screen.
• Mapper draws a line back to main entrance for its user
  • This must be enabled in the config (seems like Zeekerss intended this feature as a compromise for the "screen duty" player)
• Mapper works in utility slot as of v80+!

As of v1.5.0, the host can now also configure the price and battery usage variables. All "Gameplay" configs sync with clients that join your lobby.

Inventory icon was generated by debbicar using RuntimeIcons and slightly tweaked. Mod icon is based on a slightly earlier version generated by MiraakThuri.
