Random Occurrence System (R.O.S.)

Introduction
My apologies. This was meant for Halloween but I got caught up in uploading the tutorial.

I've been playing a lot of horror games lately; mostly Dead Space. I got to a point in the game where there was a door that was chained and kept shaking, like something wanted to get out. I walked in front of the door and thought, "What if something actually popped out of that door?" That's when I got the idea for R.O.S. I figured that the reason some RM games don't scare players is because the player already knows what's coming. What people are afraid of is the unknown. I desperately wanted to make this system for RPG Maker but never found the time. But this October, I found the time to really devote myself to RPG Maker. Enjoy the system!


About the System
This system requires some heavy eventing and editing. The level of difficulty is from moderate to high so have patience with the system.

Available in the Demo:

Enemies

• Regular (Set up by you. ABS compatible)
• Self Checking (Runs on Parallel Process to check their own X and Y values. ABS compatible)

Traps

• Active Trap (Triggered by Player Touch and runs once. Player must step on trap again to re-activate)
• Active Persistent Trap (Runs on Parallel Process and triggered by player or other conditions)
• Passive Persistent Trap (Runs on Parallel Process and is independent. Processes as soon as player enters the map)

Ventilation System (Requires Self Checking enemies)

• Exits (For enemies to exit the vent system and surprise the player)
• Entrances (For enemies to re-enter the vent system to hide from or chase the player)

A more detailed explanation is found in the demo. It explains all the tips you need to get this system functional.

It's hard to understand the system just from pictures but here you go.
