User:AdminSR1/Scripting Protecting Plug-in Files

This script will allow you to only allow access to an esp plug-in file if requirements are met.

Usage

There are many reasons why you may want to protect a plug-in file from only allowing authoirsed users to test said file or if you want to use said file for personal use. This method can also be used to prevent piracy.

Preperations

First lets make a quest to handle our script so that it will run as soon as the player loads into the game.

To do this go to the Object Window and under the Character tab, open the Quests sub menu. Then right click on any quest and click New. Give this quest an ID and insure that Allow Repeated Stages is checked on the Quest Data menu. Then lets make a new stage under the bQuest Stages menu and call it stage 10. Make sure that Run On Start is checked. The close the Quest Window and reopen the same quest we just made. This will give us access to the stage fragments. Lets go over to the Scripts tab on the far right end of the quest window and make a new script by pressing Add followed by [New Script].

Once you have clicked on [New Script] name it what you would like and click OK. Now please refer to the Script part of this tutorial.

Script

This is an example script. It can be used to prevent access to a plugin file by displaying a series of messages and menus that will either let the player into the game with the plug-in or take them back to the main menu where they can uninstall the plug-in file.

EXPLANATION:

The first part of the script uses the Group Function. This is used to group properties together and make a cleaner look to the script. Note that groups, like other functions have to be ended using EndGroup. Group Functions can be named which is what is after the word Group, the first group is named Reqiured_Properties. Group names can not have spaces so underscores will have to do. Once a group has been created, script properties can be put inside them. Using {} underneath either a group or a property will allow you to add a note so that you can refer back to it later.

The next part of the script after all properties have been declaired is the Requirements Section, which is where you can define what should be true, or even false in this case. We are using Game.GetPluginInstalled() to check if a plugin is installed and enabled in the players game. If so a message will be showed.

The Self.Reset() and Self.Stop() Functions are part of the Quest scripting and stop and restart the quest so that the message will be displayed if the player go to the menu and loads the game again.

The functions below all of this are what control happens with messages and menus where aiButton is the integer that will correspond with what button is pressed in the message box and then will follow out set instructions. These functions are then called such as how the first function called Menu() is called when the user has met the reqiurments of the script.

; -------------------------------------------------- Contributors & QAT's  This section will display current testers of this Alpha Release mod in the form of a message
Function QATs(int aiButton = 0)
aiButton = Contributors01.Show()
	If aiButton == 0
		Menu()
	EndIf
EndFunction

Finishing

After you have finished with your script and it has successfully compiled, go back to that stage we created earlier and under the kmyQuest tab just above the fragments window, select the script you just made. Then in the fragment type kmyQuest.Start() . This will insure that the script will start when the player loads into the save game.

And you are done! You now have a plug-in file that will only load if the user mets your requirements.
