Region Offset - Change Encounter Tables On The Fly

[sawyerfriend]

Hello everyone! I'm trying to do one post a day until I make a habit of it, so part of that will be posting some utilities that I've made in the past. This is a favourite of mine!

Region Offset

Have you ever wanted to make random encounter tables update mid-game? For example, after a critical story moment, areas may get swarmed with more powerful enemies, or a location might temporarily get overrun with an enemy faction. In the past, I've made duplicate maps to accomplish this effect, but I later created a plugin to achieve this. That plugin is now yours!

How To Use It

The plugin contains a Region Offset Variable parameter. Select the variable you want to use to define this, and the game will add this number to the current regions on the map. Here's an example:

On this map, I have three regions: 1, 2, and 3. But if you look at my encounter table, you'll find that I also refer to regions 51, 52, 53, and 101, 102, and 103.

Once the plugin is installed, at any point in the game I can simply change the offset variable to 50, and I'll gain access to the random encounters in that range, or 100 to gain access to those other encounters. If I want to go back to the original encounters, I can simply return the variable to 0.

Important!

This plugin does NOT modify regions, only the encounter tables within those regions. Any other scripts or events that refer to regions will refer to their default region, i.e. the region shown on the map in the editor.

PLUGIN

Here's the plugin, simply copy and paste this code!

//=============================================================================
 /*:
 * @plugindesc v1.0.0
 * Use this to offset region enemies using a variable.
 * @author Sawyer Friend
 * @help
 * This lets you add a flat number to region encounters based on a variable, so you can change what enemies appear at given times.
 *
 * Simply define in the plugin params which variable that you want to add onto the regions, then change that variable as desired.
 *
 * (Example: Variable 6 is the variable that changes regions. If you set it to 1, every Region 1 will now pull enemy data from
 * Region 2, etc.)
 * 
 * NOTE: This plugin only affects the enemy data. The regions will still be recognized as their normal region number for any other
 * purposes (this is to ensure compatibility with other plugins and features)
 * 
 * @param Region Offset Variable
 * @desc This is variable that will offset the regions.
 * 0 will not offset any region.
 * @default 0
 *

Sawyer.Parameters = PluginManager.parameters('SawyerRegionOffset');
Sawyer.Parameters = Sawyer.Parameters || {};
Sawyer.RegionOffset = Sawyer.RegionOffset || {};
Sawyer.RegionOffset.variable = Sawyer.Parameters['Region Offset Variable'];


Game_Player.prototype.meetsEncounterConditions = function(encounter) {
	var region = Math.floor(this.regionId() + $gameVariables.value(Sawyer.RegionOffset.variable));
    return (encounter.regionSet.length === 0 ||
            encounter.regionSet.contains(region));
};

Most of my plugins are proprietary and made for use specifically within my games' systems, but I'd be willing to clean some of them up to make them public here as well. I hope this helps you guys!

ah sweet, that's a clever way of handling it!
