Introduction
While RPGMMV event system is really cool and handy, it misses some concepts from normal programming languages. You can always use JavaScript, to make more "tight" actions, but if it don't fit in a single Script command or takes time, then it's really hard to return on Events "rails".

And you have to use a lot of common events or variables or constantly copy-paste code because of some limitations.

Plugin tries to resolve that as much as possible, to leave global variables for global stuff and tracking, to leave common events for a really common stuff and to have more straightforward event code.

Features
It's not like you cannot do anything from that list without this plugin, but in much less convenient way.

• imperatively run other events on the map (possibly as parallel, imitating any other event, mixing with another, etc);
• pass values from child events to the parent (like functions in normal programming languages!);
• scheduling events;
• run events just before leaving the map;
• doing this directly from block of current event without spreading it even on the map;
• generating proper move route commands on the fly from JS;
• tweaking next commands in the current event in any way;
• turning "Show Choices" into large programmable conditional branches;
• and actually just build your own "Show Choices" tree without most limitations.

How to Use
!! Must be under YEP_CoreEngine in plugins list !!

Plugin does not provide any configuration, you just add it as is and use.

Plugin Commands / Script Calls
Up to date commands list (almost every go into "Script Calls") available here. Several simple script commands are easy to use (and they're on screenshots), others are just a more convenient API interface for manipulating events for those who know how and not really designed for beginners.

Demo
Demo project available here. It has most of the commands used with detailing in the comments.

Download
Downloadable here. I may update it really often, so it's easier for me to have it in a more accessible for me place.
In case of updating, version 1.7.3 as an example:

• first number (1) increases for breaking changes, backward compatibility (except for "unstable" features) is partially lost;
• second number (7) increases for new features, updates should be safe and may bring something new;
• third number (3) is bugfixes or very minor new features (accepted one more type of argument, for example).

Terms and Credits
Use anywhere you want, commercial is ok, crediting is mandatory.
Possible plugin extensions in case of sharing should not include original plugin, download links for it should lead to this thread or this page.
