Making your own maps for DTA tutorial - The Dawn of the Tiberium Age Mod for C&C: Tiberian Sun

Here are a few things you should know before you start mapping:

• In FinalSun, the snow theater is really DTA's temperate theater and the temperate theater is really DTA's desert theater.
• DTA does not have any slopes, so make sure that whenever you make a map it has the minimal height to prevent terrain damage from occurring. 
• Make sure AutoShore is disabled or shores will be placed around any tile you place on the map. You can find this option under the 'Options' drop-down menu.
• Make sure you never place tiberium on impassable tiles, because this will cause harvesters to move onto those tiles and get stuck.
• Never select blue tiberium from the side bar; this will make FinalSun crash.
• Experiment with overlappting tiles a lot; you'll be able to create many interesting shapes this way and in the case of horizontal and vertical shores it's even necessary to everlap when you want to connect a diagonal shore to them.
  The following images show which cells should be overlapped to connect a diagonal tile to a horizontal or vertical one (click to view in full size):
  
  
• After finishing a map, save it with a ".dpr" extension (or simply rename "yourmap.mpr" to "yourmap.dpr" after saving it).
• Whenever you finished a map for DTA, you can upload it at the DTA maps forum at Project Perfect Mod.
  Maps that are good enough will be included with the next version of DTA (with the authors of the maps credited in the readme file, naturally).
