Optionally specify a folder name for the map. The folder may be delimited by backslashes to nest the map multiple levels of folders. The folder will become the parent of the map in the project tree. It is for organizational convenience in the project tree only, and does not affect other uses of the map.

The name of a map must be unique among all map names in the project. A name must begin with a letter and contain only letters, digits and spaces.

Each map is associated with its own source code file in the generated project. The name of the map determines the filename of the source code file containing all code for the map (which is the name of the map with "_Map.cs" appended).

Simply stated, this is the size of the map. The size is specified independently of the layer sizes because you may have layers that you don't want to be entirely visible within the map (for example if a portion of a layer is used only as a source of tiles for copying to another part of the layer). To understand this size, consider a map with a scrollable size of 800x600 displayed on a screen that shows 640x480 pixels. Such a map will be able to scroll 160 pixels to the right (800 minus 640) and 120 pixels down (600 minus 480). Notice how the display size plus the distance that a map can scroll represents the total scrollable size for the map.

To easily calculate a reasonable value for the Scrollable Size based on the layers within the map, use the "Wizard..." button. It will allow you calculate a size based on a desire to make all areas of all layers visible or a desire to keep the map from scrolling to any area where any one of the layers will not fill the display. (You can also select a subset of layers on which to base this calculation.)

Keep in mind that changing a layer's scroll rate or size, or changing the resolution of the game after setting this may result in layers no longer exhibiting the desired behavior specified in the wizard, until you update the Scrollable Size in accordance with new conditions.

Each side of the display has a scroll margin associated with it on each map. This number is used when using rules that scroll the map. Scrolling a sprite into view can use the scroll margins of the map containing the sprite to position the view so that the sprite will maintain a minimum distance between the edge of the display and itself. A bottom scroll margin of 100, for example, will ensure that the sprite doesn't come within less than 100 pixels of the bottom of the display unless it has reached the bottom of the map.

If you don't want the map to completely fill the display when it is active, you can specify a smaller area in which to draw the map. If you want to map to fill the display regardless of the resolution, you can specify all zeros, and the size will default to fill the display.
