OnUnTouch:

Description

Defines an area that when walked into will trigger one of two event labels. If
it is a Player, trigger OnTouch: label. If it is a monster, trigger
OnTouchNPC: label. The OnUnTouch: label works opposite way. This label trigger
when a player leave the area.

Calculating spawned area

File:Ontouch.jpg These triggers
will define an area, centered on the NPC and spanning triggerX cells in
every direction across X coordinate axis and triggerY cells in every
direction across Y coordinate axis. Thus each one will have N*2 cells, where N
is triggerX or triggerY , plus the one that the NPC is.
Unlike in arithmetics X and Y will also be taken into account when calculating
the area that will trigger the NPC. There are four quadrants, each with
triggerX * triggerY cells plus both axes.

Note that each coordinate is a cell and does not represent map
coordinates!

4*(x*y) + 2*x + 2*y + 1

A simple way to measure the area of any polygon that will be covered by
OnTouch is ( _triggerX 2+1)( triggerY 2+1)_
Trick* : Using "end;" at the beginning of the script stops players from
executing the script by clicking on the NPC, so they can only execute it if
they walk into the specified area.

Event labels

Two event labels are defined and each one handles one of two block types BL_PC
or BL_MOB id est a player or a mob.

OnTouch:

Handles player types (BL_PC)

OnTouchNPC:

Handles mob types (BL_MOB)
If no trigger label is defined the code will execute from the beginning of the
script, the same way that it would if someone clicked on the NPC.

Example

prontera,147,153,3  script  Mary    71,3,3,{
    end;

OnTouch:
    mes "[Mary]";
    mes "Have you seen my lamb?";
    close;
OnTouchNPC: // NO ONE IS ATTACHED!
    announce "A mob passed here",bc_blue|bc_all;
    end;
}

This script will spawn 3 cells in each direction plus a cell in the center.

4* _3_ * _3_ +2* _3_ +2* _3_ +1 = 49

Or

( _3_ *2+1) * ( _3_ *2+1) =
7*7 = 49
