Range Checks

[killerogue]

Hello! I was working on RC with Chandler earlier today and I came up with these distance checks.

I needed them for a few things and I thought it might be awesome to let the public be able to use them as well.

The class checks for the NPC can be changed as you wish. There is another function to this set. But I have not completed it yet, so when I do I'll make sure to post it here! =D

PHP Code:

public function playerInRange()
{
for ( pl: players )
  {
    if ( pl.x in this.getPlayerVec( 2, 2 )[0] )
    {
      if ( pl.y in this.getPlayerVec( 2, 2 )[1] )
      {
        return true;
      }
    }
    else
    {
      return false;
    }
  }
}


public function enemyInRange()
{
for ( cl: findareanpcs( this.getPlayerVec( 10, 10 )[0], this.getPlayerVec( 10, 10 )[1], 64, 64  ) )
  {
    if ( cl.isinclass( "mud_enemyfunctions" ) )
    {
      if ( cl.x in this.getVec( 2, 2 )[0] )
      {
        if ( cl.y in this.getVec( 2, 2 )[1] )
        {
          return true;
        }
      }
      else
      {
        return false;
      }
    }
  }
}


public function getPlayerVec( xDist, yDist )
{
  temp.dx = player.x + 1 + vecx( player.dir ) * temp.xDist;
  temp.dy = player.y - 1 + vecy( player.dir ) * temp.yDist;

  return ( { temp.dx, temp.dy } )
}
