Colored Locked Doors
|
|
|
|
This script handles the blue, green, red, yellow and small-key doors.
|
|
|
|
Each door has a corresponding key that will unlock it. Small Key doors consume a
|
|
small key when unlocked for the first time.
|
|
|
|
Options: "unlocked" can make the door unlocked by default when the level begins.
