Event Positions

Author: Tsukihime

 

Overview

 

Often times you want to create event conditions for when the player leaves a particular tile.

For example, if the player is standing on a push button, you want to check whether the player has left or not.

 

This script provides extended position-tracking information, such as the last x,y position a character was on and the last region ID.

 

Features

• Get the player's previous position and region
• Get an event's previous position and region

Usage

 

These are mainly for events.

You can access position information by the standard

 

$game_player.x
$game_player.y
$game_player.region_id
$game_player.last_x
$game_player.last_y
$game_player.last_region_id

$game_map.events[event_id].x
$game_map.events[event_id].last_y

You can also use some methods that make this easier

 

player_pos
player_last_pos
event_pos(event_id)
event_last_pos(event_id)

These return a list of values corresponding to your position information

 

player_pos ==> returns [x, y]
player_last_pos ==> returns [last_x, last_y]

The "last position" is updated whenever you successfully move to a new position. So if you're walking against a wall, your last position doesn't change (and it shouldn't cause you haven't moved yet).

 

Example

 

Suppose you really were making a push-button which is activated when you stand on it, and deactivated when you leave. Actually, you don't need this script for it lol

 

Anyways you'd have two event pages

The first page has a conditional branch

 

if player_pos == event_pos(@event_id)
#turn it on
self-switch ON

Second page has a conditional branch

 

if player_pos != event_pos(@event_id)
#turn it off
self-switch OFF

While you can do this without using a script, you must agree that it's much more compact.

 

Another example is the ground-breaking request which I wrote this script for, where you are checking arbitrary tiles and arbitrary player positions.

I can use this script to, for example, make the flames to go to the top of the barrels instead of the middle? Sorry if I completly misunderstood the script.

Just noticed that a lot of my dropbox files are corrupt.

I don't know which ones are still being referenced so I'll just go and update all of it with proper versions.

Excuse me, but am i using your script correctly?
