Jump plugin

じ☆ve冰风

Current version: 2 (updated dec 1st)

Version 2:

Added the option alwaysAllowJumping. If false, the player will not jump if the destination is a tile that he could have reached by simply walking [jumpDistance] tiles forward.

Version 1:

Initial release.

Intro:

This plugin allows the player to jump on the map.

You can specify terrain tags that the player can jump over. By default, this terrain tag is number 1. This is configurable. Don't forget to apply this terrain tag to tiles such as water, or your player won't be able to jump over anything.

Features:

- Configurable terrain tags that can be jumped over.

- Directional passage detection (see attachment).

- Proper handling of looping maps.

- Optionally jumping over "same level as character" events. The default behavior is configurable and overridable for each event.

- Ability to toggle the jumping ability on or off.

- Player can jump onto "below character" events, such as lily pads in the water.

- Plays nice with other plugins.

The attachment shows a jumpable path. The player can reach the chest without the need for any events for the jumping. It's all handled by the plugin.

Configuring the jump key

This plugin does not include any logic to expand upon RMMV's default keymapping. There are other existing plugins that you can use for that. The sole purpose of the plugin is to enable jumping.

Download:

Copy the contents of the code box in the spoiler and simply save it to your plugins folder. The name of the file doesn't matter.

The plugin is freely available for commercial use.

Spoiler/*:* @author Wouter Alberts (Sulsay)** @plugindesc Enables jumping over specified terrain tags and, optionally, events.** @param alwaysAllowJumping* @desc Boolean - If false, jumping is disabled when pointless, to prevent "bunny hopping" all over te map.* @default true** @param eventsAreJumpableByDefault* @desc Boolean - Determines if events at level "same as character" can be jumped over by default.* @default true** @param jumpableTerrainTags* @desc Integer[] - The terrain tags that can be jumped over.

If false, the player will not jump if the destination is a tile that he could have reached by simply walking [jumpDistance] tiles forward.** Version 1:* - Initial release.** Available for commercial use for free.** If you set eventsAreJumpableByDefault to true, you can override this behaviour with an event note containing "<!jumpable>".* Inversely, if eventsAreJumpableByDefault is false, override it with "<jumpable>".* This behaviour only applies to events with priority "Same as character".** To customize the sound that plays when jumping, supply a json object with at least the key "name".** jumpableTerrainTags is an array of integers containing the numbers of terrain tags that your player can jump over.* Apply such a terrain tag to water, holes in the floor and other small obstacles that appear jumpable to the player.** The jumpKey is set to "pageup" (Q) by default. Use a plugin for additional key mappings if you want to have more options than what RMMV supplies by default.* Additional key mappings are not part of this plugin, because a plugin should do as little as possible and minimize the risk of introducing conflicting behaviour.** Plugin commands:* - toggleJumpingEnabled* Toggles the jumping feature on/off. Supply an optional boolean argument (true or false) to enable or disable it.*/(function () {    var fileNameWithoutExtension = document.currentScript.src.split('/').pop().split('.')[0];    var options = PluginManager.parameters(fileNameWithoutExtension);    for (var key in options) {        if (options.hasOwnProperty(key)) {            try {                options[key] = JSON.parse(options[key]);            }            catch (err) {                var stringValue = String(options[key]);                console.warn('Failed to parse parameter "%1", falling back to string value: %2'.format(key, stringValue));                options[key] = stringValue;            }        }    }    var sound = {name: 'Jump1', volume: 100, pitch: 100, pan: 100};    ['name', 'volume', 'pitch', 'pan'].forEach(function (key) {        if (options.sound[key] != null) {            sound[key] = options.sound[key];        }    });    options.sound = sound;    options.eventsAreJumpableByDefault = !!options.eventsAreJumpableByDefault;    var priorityToRevertToOnLand = null, // This is set at the start of a jump, and gets reset to null upon landing.        isJumpingEnabled = true;         // Flag that can be set with the plugin command "toggleJumpingEnabled" (which accepts optional true or false argument).    var Tile = (function () {        function Tile(x, y) {            this.x = x;            this.y = y;            this.adjustXForHorizontalLoop();            this.adjustYForVerticalLoop();        }        Tile.prototype.adjustXForHorizontalLoop = function () {            if ($gameMap.isLoopHorizontal()) {                var mapWidth = $gameMap.width();                this.x += this.x < 0 ?
