Density Question

Exophus	It depends. Do you want to check all of the turfs two tiles away from the mob? -Exophus

Satans Spawn	No, I just meant the square two tiles ahead of the mob. §atans§pawn

There's probably an easier reason, but I am tired.. It's 5:02 AM and I didn't sleep yet. :(

for(var/turf/T in world)
  if(T.x==src.x&&get_dist(src,T)==2)
    //do everything here...
    //If it were anything but an area or turf you should add a break here in case there are multiple objects or mobs in that tile.

Think something along the lines of:

  // Alright, let's cut to the chase:
  // We want to get the turf two in front of us.
  // Here are the things we need to do:
  // NORTH: Y + 2 
  // SOUTH: Y - 2 
  // WEST: X - 2
  // EAST: X + 2
  // NORTHEAST: X + 1, Y + 1
  // SOUTHEAST: X + 1, Y - 1
  // NORTHWEST: X - 1, Y + 1
  // SOUTHWEST: X - 1, Y - 1

var/turf/T = locate( ( dir == EAST ? x + 2 : ( dir == WEST ? x - 2 : ( dir == NORTHEAST || dir == SOUTHEAST ? x + 1 : ( dir == NORTHWEST || dir == SOUTHWEST ? x - 1 : x ) ) ) ), ( dir == NORTH ? y + 2 : ( dir == SOUTH ? y - 2 : ( dir == NORTHEAST || dir == NORTHWEST ? y + 1 : ( dir == SOUTHEAST || dir == SOUTHWEST ? y - 1 : y ) ) ) ), z )

It's one massive line, but I'm fairly certain it might get what you want done. Uh, it's highly unreadable, but I sort of explained what I did up above it. You might want to go over it again and make sure I did it all correctly, as it's 5 AM and I'm somewhat tired. ~_~

Satans Spawn	The problem with both of your codes (as far as I know) is that turfs do not have an x value to compare with mine, otherwise this crisis would have been averted... :( but thatnks anywho :D §atans§pawn

Jul 30 2006, 1:02 am In response to Satans Spawn
Audeuro	Where are you placing this stuff? Mine should work nicely as long as it can access a mob's x, y, and z.

Jul 30 2006, 1:02 am In response to Satans Spawn
Exophus	I just realized mine wouldn't have worked for what you wanted anyways. X_x I misunderstood.. Like I said.. Tired. I could've done that method a lot better, too. Dunno what I was thinking. -Exophus

Basically, I want to check to see if the player is able to hop over a fence or not... This is still the very early stages of the game, so I plan on making it better, but for now this is just to find out how to do it and then elaborate it.

Audeuro	So are you trying to check the space on the other side of the fence, or what?

Here is my current code. I didn't write an optimized code, obviously, I just went with something that would work, and this does just that. However, I am now looking for ways that this can be optimized. Any suggestions are welcome.

First of all, get rid of all of the direction checks. You should be able to use get_step() to get the turf in a certain direction instead of using locate(). Also, block() returns turfs, so you your failure check will not always be correct.

turf/outside/fence
  Click()
    if(src == get_step(usr, usr.dir))
      var/turf/check = get_step(src, usr.dir)
      if(check.density) return // is the destination dense?
      for(var/atom/A in check)
        if(A.density) return // are there any dense objects in the destination?
      usr.loc = src // set the player's loc onto the fense
      spawn(3)
        usr.loc = check // then set them to the destination

Satans Spawn	I replaced my stuff with yours, but it doesn't seem to be working. I will continue playing with it, but from what I can figure out is it won't get past "if(src in get_step(usr, usr.dir))". I put in a check of world<<src under that line and indented properly, but there is no output. §atans§pawn

Jul 30 2006, 10:50 am In response to Satans Spawn
Unknown Person	Sorry, I forgot that src was a turf. Since get_step() returns a turf, you have to compare src with the get_step(). I modified my original post. ~~> Unknown Person
