Graal Forums - Range Checks

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 } )

}
