Machinery

• Adding machineries to a map can enrich the level's logic.
• This chapter will introduce the characteristics of all official machineries.
• This chapter can be considered an official machinery compendium.

Doors and Keys

TIP

• Doors and Keys can be found in Assets → Items → DoorsAndKeys.
• There is no functional difference between a Normal Key and an Opaque Key. However, when the camera is above water and a Normal Key is in the water, the key will not be rendered. Therefore, please use an Opaque Key when placing keys in water.

LockedLocked_Door_Blue	Key_Blue or Key_Blue_Opaque	The Door and Key's states reset after the player dies.
LockedLocked_Door_Green	Key_Green or Key_Green_Opaque	The Door and Key's states reset after the player dies.
LockedLocked_Door_Red	Key_Red or Key_Red_Opaque	The Door and Key's states reset after the player dies.
LockedLocked_Door_Cyan	Key_Cyan or Key_Cyan_Opaque	The Door and Key's states do not reset after the player dies.

TIP

• Physical Machineries can be found in Assets → Items → Machinery.
• Some machineries may not be very physical.

Supplies

TIP

• Supplies can be found in Assets → Items → Misc.

Supply Name	Characteristics	After Death	Notes
Cure	Restores 15 durability to the player ball and gives 15 score.	Resets	Does not give score after resetting.
Electric	Restores 50 power to Sticky Ball, repels other balls and causes damage.	Resets	Cannot repel Steel Ball, not triggered by Ice Ball.

Ball Switchers

TIP

• Ball Switchers can be found in Assets → Items → Switcher.

• When the player ball is within the Ball Switcher's trigger area, its scaleIce Ball and powerSticky Ball can be rapidly restored.
• The ball-switching process is triggered when the player ball enters the trigger area or touches the Ball Switcher.
• When the player ball is already inside the trigger area, the ball-switching process will not be triggered again.

Rail Cart

TIP

• Rail Carts can be found in Assets → Items → RailBlock.

Usage:

• Create one or more sections of rail, which can be single or double rails.
• Based on the rail type and your actual needs, select a suitable rail cart type and place it on the track.
• Adjust the position of the rail cart. Normally, the cart's Y-axis height should be the same as the rail's Y-axis height.
• Select the cart, and in the Inspector → Item Links → Settings, add all the rail items the cart needs to travel on.
  • In the Hierarchy, select the rail items and drag them one by one into its list.

Death Area

TIP

• The Death Area can be found in Assets → Items → Misc.

• Please ensure the Death Area is large enough to cover all possible areas where the player ball might die.
• When the map involves the Balloon Ball, please also cover the area above the path with a Death Area.
• Try not to use Death Areas to block shortcuts.
