[Scripting Question] Alternative way for the trainers to spot the player

[HarmonyConcept]

In Essentials, the trainers spot the player when he walks into their line of sight.

How would I do an alternative system, where the fight starts if the player is too close of the trainer?

I would like the trainer to spot the player as on the picture on the right. He would turn towards the player and engage him.

Also as the trainer would move, it can't be done by eventing each case.

If anyone got an idea of how to start... I'd be glad to hear it!

You can put a Players Touch event that makes the trainer move and face to him according to the tile the player is on, and use switches to end it with no loop continuity.

It could do the trick for a static trainer, but:

Also as the trainer would move, it can't be done by eventing each case.

It could do the trick for a static trainer, but:

You can just make an event that moves all the events with the same movement route the trainer has.

Though I would imagine if there are a lot of trainers it could cause some lag.

First of all, into Game_Player script section, before def pbCheckEventTriggerAfterTurning, add this:

  def pbTriggeredAreaEvents(triggers,checkIfRunning=true)
    result = []
    # If event is running
    if checkIfRunning && $game_system.map_interpreter.running?
      return result
    end
    # All event loops
    for event in $game_map.events.values
      next if !event.name[/^Area\((\d+)\)$/]
      distance=$~[1].to_i
      # If event coordinates and triggers are consistent
      if pbPlayerInEventArea?(event,self,distance) and triggers.include?(event.trigger)
        # If starting determinant is front event (other than jumping)
        if not event.jumping? and not event.over_trigger?
          result.push(event)
        end
      end
    end
    return result
  end

Then, into def pbCheckEventTriggerFromDistance(triggers), after this line:

ret.concat(pbTriggeredCounterEvents(triggers))

Add this line:

ret.concat(pbTriggeredAreaEvents(triggers))

Then, into def check_event_trigger_touch(x, y), after this entire lines:

      if event.name[/^Counter\((\d+)\)$/]
        distance=$~[1].to_i
        next if !pbEventFacesPlayer?(event,self,distance)
      end

Add the following lines:

      if event.name[/^Area\((\d+)\)$/]
        distance=$~[1].to_i
        next if !pbPlayerInEventArea?(event,self,distance)
      end

Into PField_Field script section, before def pbEventFacesPlayer?(event,player,distance), add this:

def pbPlayerInEventArea?(event,player,distance)
  x1=event.x
  x2=event.x
  y1=event.y
  y2=event.y
  found=false
  for i in 0...distance
    x1-=1
    x2+=1
    y1-=1
    y2+=1
    if((player.x==x1 && player.y==event.y) ||
       (player.x==x2 && player.y==event.y) ||
       (player.x==event.x && player.y==y1) ||
       (player.x==event.x && player.y==y2))
      found=true
      break
    end
  end
  if((player.x==event.x-1 && player.y==event.y-1) ||
     (player.x==event.x+1 && player.y==event.y-1) ||
     (player.x==event.x-1 && player.y==event.y+1) ||
     (player.x==event.x+1 && player.y==event.y+1))
    found=true
  end
  return found
end

IT'S VERY IMPORTANT THAT YOUR EVENT MUST TO BE NAMED Area(x), LIKE Counter(x), AND IT MUST TO HAVE Event Touch TRIGGER. CHANGE THE X VALUE TO THE MAX DISTANCE OF THE EVENT'S SIGHT.

I followed those instructions and it seems to work flawlessly! Many thanks!
