Tested SendAll(), end of this prototype

After a significant modification to the Codebase library, I imported a lot
of the Codebase updates back to this porject. Some files that exist in
Codebase still carry the zlib license header; these files are still under
the zlib license.

Following a significant struggle with SDL_net, I've decided to ditch that
library and write my own version. It currently only supports TCP
networking, and only works on windows platforms,  but it is sufficient at
this time.

+Tortuga is a 3/4 top down multiplayer RPG set in a large archipelago occupied by warring pirate clans. The emphasis of this game is on multiplayer competition, exploration in an open world, and solo adventuring. The game runs on a Minecraft like server system with a goal of about 50-100 players on a single server. The player characters are tied to the server where they are created, and are susceptible to permadeath: deletion of a character upon death. The servers are designed to allow a large amount of modification by the hosts.
+
+## Libraries
+
+* [SDL](http://www.libsdl.org/) - Simple DirectMedia Layer API
+* [SDL_net](http://www.libsdl.org/projects/SDL_net/) - SDL's networking extension; modified source included under libs/SDL_net
+* [Codebase](https://github.com/Ratstail91/Codebase) - files included locally; modifications will be included upstream further into this project.
+
+## Instructions
+
+* This project uses C++11, which is available via GNU (or MinGW) 4.7, or Visual Studio 2012. Personally, I'm using MinGW 4.7.2.
+* You need to build the library in the common/ directroy before any others.
+* I'm trying to keep this as IDE agnostic as possible, so if you use an IDE, please add it's files to .gitignore.
+* You can read more details on the GitHub wiki [here](https://github.com/Ratstail91/Tortuga/wiki).

-My game Tortuga will have permadeath; it's actually one of the first design decisions I made. How to implement it, however, is another decision all together.
-
-A while ago, before the implementation of hardcore mode, I was playing on a Minecraft server that boasted something close to permadeath: your account would be banned for 15 days, so long that it's almost unavoidable that you'd lose all of your hidden items. This was a brutal server; the further you went from spawn, the more dangerous it became, not less. If the natural hazards didn't kill you, another player would.
-
-I loved it.
-
-Although I haven't been back to that server since I died for the last time, the experience will stay with me forever. I'd played and died on that server a few times, each time I had to wait for my ban to clear. I never really lost much, since I never survived for very long. Even today, in a single player world, I'm likely to die on the first night.
-
-After playing for a while, I began to understand the mentality needed to survive there. Always fear other people, never take risks, and never hoard valuable items if they could be better spent keeping you alive. One day, the last day I played, I found a hole in the ground that someone was obviously using as a "hidden" base. I tried to get in, always careful not to trigger any traps. However, while I was trying to get in, the owner came home.
-
-I was suddenly attacked from behind, I barely had enough sense to dig down, since they were wearing enchanted diamond armour. I had no chance against them. I thought I was safe, digging 10, 20, 30 meters down, but no, they poured lava down the hole and plugged it up. I was a gonner, and I knew it. I was futilely digging and thrashing around in what was now my tomb, about to lose my life. I'd survived for so long, only to lose it all by not keeping a lookout.
-
-When the game over screen flashed up, I screamed. I screamed, and screamed, and screamed. For 5 minutes, my mind was blank, nothing but hatred and pain and loss. I'm sure you've seen the video of the angry German kid who died in WoW, but have you ever actually experienced that pain? Have you ever worked so hard, and lost it all?
-
-For days afterwards, that loss was all I could think about. Even now, that experience stays with me. What about that game, that server, invoked so much pain that I almost lost consciousness from screaming? Me of all people, who thought he was invincible?
-
-I've played games that have moved me, terrified me, made me fall in love and fight for the people that I care about. But never have I played a game that has made me feel pain and loss like that. I died that day. Me.
-
-Pain and loss are part of life, but not games. Permadeath seems like the obvious choice for creating a sense of loss for the player, but there are so few games with permadeath, and even fewer multiplayer games. Pain and loss can be conveyed in other ways, I'm sure anybody who's played Final Fantasy 7 knows that, and some games are especially well suited to delivering that message. However, for a player to feel like they are the one who's died, that is a challenge.

articles/collision-logic.md

-Abstract:
-
-The goal of this pseudocode is to create a collision system that brings several
-colliding bodies to a near-contact state (no space between the bodies, but not
-overlapping), while preserving the motion of said bodies. For simplicity, I've
-decided to use a square box (BoundingBox, or BBox for short) for the collidable
-bodies.
-
-Example:
-
-My current game has a tiled-map, where the tiles are arranged on a 2D grid. The
-tiles each have a flag indicating if they are solid (i.e. collidable) or not. I
-also have characters walking around on these tile maps, that must not intersect
-with solid tiles. For stylistic reasons, I want characters moving at an angle
-to "slide" along these walls, and continue along with their original velocity
-when they've circumvented the obstacles.
-
-I'd also like to keep the possibility of non-grid collisions using this logic
-open (for objects like trees, etc.) if the code allows it.
-
-Obviously, there are many in depth issues that I will need to  take into
-account when writing this logic, that have been glossed over or omitted in this
-article.
-
--------------------------
-
-```
-	velocity = motion + speed
-	if (collision(position + velocity)) then
-		if (collision(position + {velocity.x, 0})) then
-			velocity.x = 0
-		end
-		if (collision(position + {0, velocity.y})) then
-			velocity.y = 0
-		end
-	end
-	position = position + velocity
-```
-
-This code is a basic outline for a collision system that preserves the object's
-motion, but it still leaves several pixels of space between the bounding boxes.
-Notably, it also treats "collision" as an abstract concept, rather than as an
-event that could happen multiple times per frame.
-
--------------------------
-
-```
-	velocity = motion + speed
-	if (collisionSimple(BOXSET, position + velocity)) then
-		velocity.x = collisionX(BOXSET, velocity.x)
-		velocity.y = collisionY(BOXSET, velocity.y)
-	end
-	position = position + velocity
-```
-
-Here, collisions are still abstract, but "BOXSET" is defined externally
-(probably as a set of solid boxes, and their positions). This does require more
-in depth calculations, as well as three specialized utility functions, but the
-results might be what I'm looking for.
-
-If there are any collisions between the player object and the given box set,
-then collisionX() and collisionY() are called to calculate the new distance
-that the character will move.
-
--------------------------
-
-```
-	bool collisionSimple(BOXSET, newPos):
-		for_each box in BOXSET do
-			if (box.overlap(PLAYER.box + newPos)) then
-				return true
-			end
-		end
-		return false
-	end
-```
-
-collisionSimple() first runs through the BOXSET, checking if any of the given
-bounding boxes would collide with the player object's new position (just
-pretend PLAYER is accessible). In this case, non-tile bounding boxes can be
-included as part of BOXSET; they're treated just the same. The optimal outcome
-is that there are no collisions.
-
-A possible, but flawed, optimization that could be preformed here is to remove
-any elements from BOXSET that do not collide with newPos, and let the other
-utility functions operate only on what remains. However, if there are any
-collisions, than newPos is not the algorithm's final result, therefore any
-final result that the algorithm would calculate based on the remaining elements
-would not have been checked against the removed elements.
-
-Just something to note.
-
--------------------------
-
-```
-	var collisionX(BOXSET, velocityX):
-		var ret = velocityX
-
-		for_each box in BOXSET do
-			if (box.overlap(PLAYER.box + PLAYER.position + {velocityX,0})) then
-				if (velocityX > 0) then
-					ret = min(ret, box.west - PLAYER.position.x)
-				else
-					ret = max(ret, box.east - PLAYER.position.x)
-				end
-			end
-		end
-
-		return ret
-	end
-```
-
-Two things: 1. collisionX() and collisionY() should be identical except for the
-axis of operation and 2. if a player object is "sliding" along a wall (or
-stuck), then these functions will be called every frame.
-
-collisionX() and collisionY() check the sides of the elements in BOXSET, and if
-there's a box that the player would collide with, given the current distance to
-move, than the distance is reduced, based on if the character is moving left or
-right (or up or down).
-
-An unfortunate bug I can already see is that this logic doesn't check corners;
-it might be possible to get stuck on a corner of a wall, but if this becomes an
-issue in my implementation I will update this article with that information,
-and you can promptly ignore it.

-The Game Map
-
-This section outlines the game’s map system. This system utilizes pagination to create a theoretically infinite game map, as well as supporting multiple tilesets in the same map. The goal of this design is to create a system with as much flexibility as possible, and simply enforcing a more rigid approach higher in the tool chain.
-
-Tile
-
-The Tile class is the basic unit of the map system, and is explicitly a POD (plain old data) structure. A tile has these members:
-
-X Position
-Y Position
-Depth
-Width
-Height
-Tile Index
-
-The tile’s X and Y positions are relative to their container region’s location. A tile’s depth allows multiple tiles to be drawn at the same location, and in the correct order; tiles with lower depths (including below zero) are drawn first. If a new tile has the same X position, Y position and depth as an existing tile, the old tile is overwritten.
-
-The width and height members indicate the graphical size of the tile (not actually used when drawing), while the tile index is the specific tile for the sheet manager to draw. A negative value here is considered an error message.
-
-Region
-
-The region class has these members:
-
-X Position
-Y Position
-Width
-Height
-Tile Container
-
-Each region in a certain map must have the same width and height, and it’s X and Y positions must be multiples of those width and height values, respectfully. The outcome of this restriction is a theoretically infinite grid of region objects.
-
-Each region holds a set of tiles corresponding to the region’s bounds. The tiles’ X and Y positions are relative to the regions’, so moving the region will move the tiles as well. A region object is created or loaded when a tile is place in it’s bounds; similarly, if a region has no tiles it should be deleted or removed from memory.
-
-The exact width and height of a region has no significant impact, other than loading or transmission costs. The width and height of a map can be adjusted as needed.
-
-Region Pager
-
-The region pager class has these members:
-
-Region Width
-Region Height
-On New Callback
-On Delete Callback
-Region Container
-
-The Region Pager class holds a series of region objects, as well as creating and deleting them as needed. Every region theoretically exists at any time, so if a non-existent region object is requested, it is created and then returned. This class also has the Prune() method, which removes all regions out of bounds from memory, and the DrawTo method, which takes (among other things) the sheet manager for the map.
-
-The width and height members must be set before the pager is used, and must not be changed while it still has regions loaded. These are used to create region objects as needed.
-
-Each pager can also have two different callbacks set: “on new” and “on delete”. If either of these are set (that is, not null) then each region object’s address is passed to these after it is created or before it is destroyed, respectfully. The callbacks are intended to be used for domain specific processes, such as loading or saving data, or even requesting data from a remote server.
-
-Tile Sheet
-
-A tileset is a series of tile graphics stored in a single file. The tile sheet class loads a tile set into memory, and provides utilities for drawing them to the screen. The tile sheet class has these members:
-
-Image
-X Count
-Y Count
-Total Count
-Begin
-End
-
-The Image class is utilized heavily here by storing the graphical data and the tile size. Any file loaded into a sheet object must have all tile images arranged in a grid pattern, and they must all have the same width and height. The width and height must be provided when the file is loaded.
-
-The X and Y counts are the number of tiles along the X and Y axis of the sheet’s image, and the total count is the number of tiles in the whole sheet (which is equal to the product of the X and Y counts).
-
-Begin is the index of the first tile on the sheet (default is zero), and end is the index after the last tile (defaults to the value of total count). These indicate the range of the tiles, and are mostly used by the sheet manager. They are also used by the InRange() method, which checks to see if a certain tile is in that sheet.
-
-Tile Sheet Manager
-
-This class has these members:
-
-Tile Sheet Container
-Range End
-
-This class is a wrapper around a key-value container, using strings as the keys. Given a specific tile index, this class will draw the correct tile from the loaded sheets, or it throws an error.
-
-Also, this class keeps track of the end of the sheet’s ranges.
