Global Interpreters for common events.

じ☆ve冰风

What is a script with such a boring name for?

Did you ever happen to use a parallel common event? It will run all across the maps. But alas, it will restart once you transfer to a new map. And thus, if you don't want that to happen, you would need heavy eventing.

The first photo shows the common event I made.
Second photo is how it reached to the third message on it's execution.
Third photo shows what happens once the player transfers to another map, while the event still works.

Well, that won't happen anymore with this script
. In the same example, the third image would show the forth message of the common event, if my script were activated.

This script works only with common events!!!

So, why do the common events restart?
What I see of it, it is because their interpreter is assigned to class instance variable, which is erased once you transfer to another map. In my script, the interpreters are stored in global array, which is also added to the save file.

What it is that interpreter anyway?
The interpreter is class in the RPG Maker, that reads and interpret events code, and execute it. Which is why it is so important to be preserved when the player transfers to another map, if we don't want the common event to restart its execution.

You don't want all common events to have global interpreter?
There are settings. You can fill an array with the id's of the common events you want to have global interpreter, or set all to work with it (which I am not sure how much that will affect the productivity).

Here is the script:

7. Optionally, you can send me link to check your finished game, if
8. my script is used on it.
10. Version 1.0. Date of release: 22 May 2018
12. Version 1.1 Date: 26 May 2018
13. Changelog:
14. Added additional aliases for more compability. Also fixed one part of my
15. code that I did not liked.
17. About the script: Did you ever had to use parallel process event, across the maps,
18. without it to restart everytime you transfer?
19. This script does just that, but only with the common events.
20. It does that by adding the common event interpreters into global array.
21. This global interpreter goes into the save file too.
22. You have the option to set this to work for all common events,
23. or only those, which id's are included in the array bellow, in the Settings
24. header.
