Terrain Replacement System
List of all Terrain Types
Terrain Type Constants (Thanks to Darthfett)
Requires a vJass preprocessor
Most of it is just a single function, which replaces a terrain type with another, in game.
The functions:
JASS:
OldTerrain and NewTerrain are the Id's of the Terrain. (For example: 'Nice' (Northrend, Ice))
NewTerrain Replaces OldTerrain.
WhichRect is the rect in which the terrain will be replaced.
This is a simpler version of the above. It replaces terrain Globally, and therefore, only takes 2 arguments.
JASS:
Similar to the version without 'reversed' on the end. This makes it easier to change terrain back to what it was. (It's easier to add a "Reversed" to the function name, than to change the order of the arguments)
The Uses:
If you want to have seasons or some sort of weather in your map, you can use this to change the terrain type as well as having the weather effect. It's also useful for dynamically changing complete areas.
A sample of this is in the test map.
Note that the 16-tile limit still exists.
How to use the Terrain Constants:
Instead of finding out what the Raw Code for the terrain you want is, you can simply use the Global Constants created by Darthfett.
To use them, use TILESET_TILE in place of the raw code.
For example:
JASS:
ReplaceGlobalTerrain(LORDAERONSUMMER_DIRT, DUNGEON_DIRT)this will replace Lordaeron Summer dirt with Outland dirt.
The Code:
JASS:

// | ReplaceTerrainTypeEx takes integer OldTerrain, integer NewTerrain, rect WhichRect |
// | OldTerrain and NewTerrain are the ID's of the terrain you want to Replace. New replaces Old. |

// | ReplaceGlobalTerrain and ReplaceGlobalTerrainReversed are shorter versions of ReplaceTerrainTypeEx. |
// | They only take the 2 terrain types, and will affect the entire map, replacing Old, with New. |
// | The 'Reversed' version is there so it's easier to switch back to the old terrain without having to |
// | change the order of the arguments (You just need to Copy and Paste the "Reversed" after the |
// | function name! |

// | -=-= Version History: =-=- |
// | Version 1: |
// | - Created TRF - Didn't work on maps larger than 32x32 |
// | |
// | Version 1.5: |
// | - Made compatible for all map sizes, However, could take over 20 seconds to completely change |
// | the terrain on some maps. |
// | - Tried timers, Worked well, with a short code, but took a few minutes to change large maps. |
// | |
// | Version 2: |
// | - Remade the entire System, using Function.Execute. Works instantly for all map sizes now, the |
// | code is also short, although a LagSpike may occur when used. |
// | |
// | Version 2.5: |
// | - Shortened code by a massive amount by doing some simple loops |
// | - Now works for all map sizes, up to 480x480. |
// | |
// | Version 3: |
// | - Fixed a major bug involving rects nor changing properly |
// | - Optimized and shortened the code even more |
// | |
// | Version 4: |
// | - Fixed a leak, and removed a pointless function |
