About this project
What does Under Construction! add?
This mod adds a “ruined” tower to the player’s world spawn. Players will need to collect resources and deposit them into the chest in order to “build” the tower. The tower has multiple levels that require multiple instances of “building” to complete the whole tower. The materials will be displayed in the top left corner of your game view.
Notes:
- Putting in more resources than what the build requires will refund the excess resources
- Materials HUD does not show unless the GUI Size is <= 3
Commands:
/tower level get(outputs the current level of tower)/tower level set <level>(1 through 3, or “max” or "reset")/tower materials(outputs the materials needed for upgrade)/tower hud(turns on/off the materials requirement display)
