Ok, what I'm talking about is if PLAYER had 4 arrows on his HUD (or let's just use 4 verbs for now). Each verb moved his camera to the north, south, east, or west of him when it was pressed. The maximum it could be moved though, was when he was still on screen, like so:

X = Screen Edges
P = Player

XXXXXXXXXX
X_________X
X_________X
X_________X
X____P____X
XXXXXXXXXXX

XXXXXXXXXX
X_________X
X________PX
X_________X
X_________X
XXXXXXXXXXX


XXXXXXXXXX
X____P____X
X_________X
X_________X
X_________X
XXXXXXXXXXX

How can I do this? Any hints or examples?

The closest thing I know is the variable client.dir

But it'll do the following:

(NORTH = default)
XXXXXXXXXX
X_________X
X_________X
X_________X
X____P____X
XXXXXXXXXXX

(WEST)
X
XXXXXXXXX
X||||||||||X
X|||||||||PX
X||||||||||X
X||||||||||X
XXXXXXXXXX


(SOUTH)
XXXXXXXXXXX
X____P____X
X_________X
X_________X
X_________X
XXXXXXXXXX


Play around with it and you'll see what I mean (note the extra X is)

Well, client.dir only rotated my screen. I need the command to move the screen so the client is against the edges of the screen.

holy crapperz o.O you can rotate the map like that o.O how come i never knew this lol... probly kuz ive never wanted to do it... oh well! good to know just incase

and! for this edge thing, just use client.view to get how far they can see

client/perspectivev = EDGE_PERSPECTIVE

Is that what you were looking for?

No no, I mean to move the screen so it's not centered on the client, not expand their view. Like in my examples.

Maybe, I'm not sure how to use that : /

I pasted that code, but no view changes happened...

Erm, nvm, just tried it. Not what I'm looking for. But it's on a good track. When you move to the edge of the screen with that code applied, that's exactly what I mean.

You could try changing the client.eye to the location of where you want it, assuming that the stage is on a fixed size:
mob/verb/North_Screen()
  client.eye=locate(round(world.maxx/2),world.maxy,z)

So you basically want the screen to move and your char to stay still? I would cheat. I would make it so if you click on a certain verb, your mob is added as an overlay to where you are standing, then you are invisible. People will THINK that they are moving the screen, but they are really just invisible.

Basically using locate, client.eye, and knowing the view size, you can accomplish this. Look them up, try to incorporate something.

Hmm, how about using client.eye.
client
  verb
    Look_West()
      eye = locate(x-a,y,z)
      mob.dir = WEST
    Look_East()
      client.eye = locate(x+a,y,z)
      mob.dir = EAST
    Look_North()
      eye = locate(x,y+a,z)
      mob.dir = NORTH
    Look_South()
      eye = locate(x,y-a,z)
      mob.dir = SOUTH
//x,y,z are the mobs current location
//a is the difference between the mobs location and where you want the center of view to be
//mob.dir sets the mob to face the direction


I don't know if that will work, just an idea.

This will lock the view though, so you will have to edit the move proc so the eye moves along with the mob.

Something like:
client
    Move(loc,dir)
        if(dir == WEST) eye = locate(mob.x-a,mob.y,mob.z)
        if(dir == EAST) eye = locate(mob.x+a,mob.y,mob.z)
        if(dir == NORTH) eye = locate(mob.x,mob.y+a,mob.z)
        if(dir == SOUTH) eye = locate(mob.x,mob.y-a,mob.z)
        ..()

Again not tested.

Horrible advice. How would you give the effect of movement anyways?

Maybe this'll help;

mob
    verb
        Up()
            panEye(0,1,1,5)
        Down()
            panEye(0,-1,1,5)
        Right()
            panEye(1,0,1,5)         
        Left()
            panEye(-1,0,1,5)
        Up_Right()
            panEye(1,1,1,5)
        Reset()
            src.client.eye = src

    proc
        panEye(var/x,var/y,var/lag,var/max)
        //description: "pans" the client eye in the specified
        //direction, at the specified speed, pausing for
        //the specified lag each iteration.
        
            //x/y: the speed affecting the respected axis.
            //if you dont want to affect the axis, set it to 0
            //lag: the wait time before the eye moves again
            //max: the maximum amount of steps the eye takes
            
            //in a loop going from 1 to max, increasing by 1...
            for(var/i = 1; i <= max; i++)
                //change the client.eye loc accordinly.
                src.client.eye = locate(src.x + (i*x),src.y + (i*y),src.z)          
                //wait for the determined lag time until repeating.
                sleep(lag)


Run that and see how she works, the only thing left out is making sure the eye doesnt go off the map.

[EDIT]

A little better description; giving the proc a negative value for the x or y parameter will move left/down (respectively). Giving values for both axises will result in diagonal movement. Using the function, you're not limited to perfect diagonals, for example if you gave x a value of 2 and y a value of 1, it'd move diagonally to the top right of the screen, going faster towards the right side.

So if using client.eye, could I tell it to move 1 square to the right of the player? Like on the X ( X is Left and Right, right?) axis? If so, how?

Ah! I got it now. I was looking for a way to make it so that you can't go off screen, but I found out. Thanks a lot ^.^

Erm... how do I extend the user's client.view with it? Because I'm trying to set it so that what you now see is your view. (For greater range on weapons and such)

In response to Pakbaum
Im not sure what you mean, do you want to increase the total visible area of the map? You can do that using the client.view, property, eg;

mob/verb/set_view(viewRange as num)
   src.client.view = viewRange


But that changes the entire screen layout along with it, shrinking the map view port to fit, which would probably get pretty annoying after a while. If byond shrunk the size of all of the tiles when view was changed instead of shrinking the size of the map view window, then that'd look a bit better.

Example of what I mean:

Player's view: 5
Weapon's range: 12

The player can't see 12 squares around him, only 5. However, his weapon can shoot up to 12 squares away. So he can look north to extend how much he can see, taking full advantage of the weapons range, instead of just the 5 squares around him.

Ah, so basically you want to use something like the code snippet I gave but make the eye go further than what the source can see, and when you tried this, it went black.

Simple fix, just add this;

mob/Login()
   client.eye.perspective = EYE_PERSPECTIVE


By default, the perspective setting is set to MOB_PERSPECTIVE, where the eye calculations are made from what the user's mob can see. Switching it to EYE_PERSPECTIVE, it'll adjust its calculations to wherever the eye's position is.
