"Kool Server for CasperLet" is a script to drop in your CasperLet units. It gives access to tenants on connected Kool Doors (and other items like Kool Rezzer Auto, Kool Rezzer Mini...), Kool Bell, and allows your CasperLet managers to do some setup.

■ What it does ?

1. When someone rents your home:
- Tenant and sub-tenants are automatically granted access to Kool Doors or Rezzers.
- They can add access for a list of names, independently for the CasperLet system.
- They can add access for one group of their choice, independently from the prim or land group.
- They can allow everyone (party mode) then switch back to private access in one click.

2. Your CasperLet managers:
- Managers get full access to Kool Door setup menus.
- When a unit is not rented, managers can set doors to allow everyone for visits, or restrict access to owner/managers only.

■ What do you need ?

- The "Kool Server for CasperLet" script (in this box!)
- The Kool Door (RP version, to buy separately) to build your houses. Or the Kool Rezzer Auto or Mini (to buy separately) to offer rezzable scenes in your rental homes. Note: Builder/Retail versions have no server connection, they need to be upgraded first.
- The CasperLet rental system (to buy separately from CasperTech).

■ How to setup ?

1. Drop the "Kool Server for CasperLet" script into your CasperLet unit (the prim which contains the "CasperLet" script). It will auto-assign an available server number (you can change it later). Ex.: First unit will be Server=101.

2. Connect the Kool Doors of this house to this server. At least the main doors. Drag mouse off the door to get the menu and in Access/Server, select the corresponding server for this house. Ex.: 101.

3. Repeat for each rental. We suggest you process one by one to avoid confusion. Each unit must have a unique number on sim. Ex.: Second unit will be Server=102, third unit Server=103... up to 399.

If you or a manager need to change a server number or the Visit mode, get the setup menu:
- Drag the mouse off the unit prim (like on a Kool Door).
- Or click the unit then click the link in chat (be within 20 m of the unit).
As two menus will pop-up, ignore the CasperLet menu to keep only the "Kool Server for CasperLet".

There you can choose a new number using the + and - buttons, list all servers on sim, or list connected doors (with their TP links).

You can also enable or disable visitors access (=everyone) when not rented. Click the 'Send' button to dispatch this visit setting to all other servers on sim.

■ Notes

The system works for the SAME OWNER, You must own everything: "Kool Server for CasperLet", "Kool Doors" (RP model) and the "CasperLet" system.

You can mix "Kool Server for CasperLet" and "Kool Server" in the same sim, but each needs a unique number. Doors which are in Access=Local (not yet connected to a server), will use Server=1 to check for manager/admin access, so it’s best to always have a Kool Server 1 active for admins.

If you need to buy "Kool Door", know that they work also without CasperLet. They work in stand alone mode, or connected to a "Kool Server" for multiple-groups access and more.

"Kool Builder Door" (Builder or Retail) do not connect to any server. They need to be upgraded to the personal "Kool Door".

This product works with CasperLet v1.55 (tested July 2025). We will do our best to keep it working with this system, yet we are not liable if CasperLet receives drastic changes or is discontinued.

For support, suggestion or any issue, contact me.

If you have more than 4 doors to configure, this script is going to make your life a living hell. It automatically assigns server numbers to CasperLet units but not the KoolDoor, which means that you'll get random combinations between the doors. What is worse, you can't manually set numbers, and if it finds two numbers it doesn't ask which server number to update so you'll be going back and forth trying to figure out which door opens with which rental unit.

Your best bet is to rezz all the rental units you need where you need them, check that they have unique server numbers, and only then go set the server numbers to the KoolDoors as you have to do that manually, anyway.

I've been setting up and test a lot of systems and pushing some limits. April 20, 2021 is the two year mark for all sites setup. I use CasperLet with Kool Server for CasperLet with the Rezzers and Doors. Casper is an excellent product and Kool Door Servers and Scrips make it even better. I've made door

Yes, I put Kool Doors in Kool Rezzers that have been set for specific configurations. Works great in doing region wide swaps.

The scripts work great in the Casper for rentals. I also use the Kool Servers on same regions for game mixes on site. I use the door scripts making builds and may have one or more moving objects in a item. Having separate servers plus with the available configuration options on each door provides a variety of options for any site.

Feel free to visit the Milda Region and check things out.

If you have a place with room and apartment rentals, and you're using Kool door scripts and Casperlet, this script automatically controls access to the doors when rented, allows for visits when not rented. I'm using it a lot and it works without a flaw.

Funktioniert einwandfrei mit den Mietvendoren.

Endlich einmal etwas, was gut durchdacht ist und auch so funktioniert.
