Usage
To set up door you first need to create network. Use keycard programmator.

First you see a network name

Currently selected user

But how to add Network and User? Type Network Name at the bottom box to set a name

Then click add button at the left Minus button deletes network

Now your menu changed and you will see something like this

To add user you need to type a username at box below (replace your network name) and then click one of these buttons as like network management above

Now you can view this user settings: his role and access level. But how do you manage it?

There are a few buttons on the right

Arrows changes user role: member / moderator / admin / founder Plus and minus buttons manages user level
Magnifying glass button used to find players. For example if you want to chage someones properties you can type his name at box below and click this button. System will found this user in selected network
But why do we need user level and roles? Now let's move to Keycard menu

Here you can view keycard's properties. First of all you need to bind your keycard to network. To do this you need a role at least moderator. Adding networks is similar to the network creation we did before

Now you can change keycard properties. To set level you have a buttons on the right. Level can be changed only by moderators and higher. But moderators can modify level in case their user level we changed in network configuration is higher. For example: User level: 5; User Role: Moderator; That means this user can set keycard level up to 5; Admins and Founder has no restrictions in management.
You propably noticed these buttons. They are manages first two parameters of keycard.

Final variant of the keycard configuration

How to add keydoors?
You need Door Programmator

First of all set it's configuration as well as your keycards

Then click on KeyDoor and manage it's configuration


!! Warning !! After setting network you need to re-open GUI
This button sets auto closing. By default keydoor closes in few seconds. But if you switch it's mode it will kept opened untill you click it with hand.

Most of the assets belongs to [Nazzy] (also mod inspired from one of his project)(https://www.youtube.com/channel/UCQ2L7O1KDK7ze75dSe1C-yg)
