PISSEDOFFNOOB'S PROFILE

Hello,

I have been searching the internet for hours to no avail. Yes, no doubt I just failed to find the information that has to be there somewhere.. I am trying desperately to understand how to use the Event Command, "Script..." All I'm trying to do is shake the screen up and down, instead if side to side. The map is the interior of a ship at sea. I'm using a parallel process event. Here is what I have tried so far.

1. Screen Effects>Shake Screen (no option for side to side)
2. Call Event with script pasted from lines 119-123 of Game_Screen from the Script Editor. Added a line "@shake_direction = x" and tried various numbers (1, 0, -1)

3. Pasted lines from Game_Interpreter and messed with them some..

Idk why the numbers in brackets aren't showing up in this post, but they are there in the script.
4. Google. Search terms like, "rpg maker vx ace call script", "rpg maker vx ace command events tutorial", "rpg maker screen shake up and down", "rpg maker vx ace scripting tutorial", "rpg maker vx ace command events script" etc. and variations of the same questions...
5. Cursing at RPG Maker, Google etc.

Please help. There are many wise people who understand what to do. It's probably going to be an extremely simple fix (hence the cursing at Google..heh) but please don't be upset at my inability to find my own answers (I'm doing that for you).

Also, how can I keep the shaking going when messages are being displayed?

Thank you kindly.
