Free Hero Mesh

The same consideration about line endings with DOS also applies to Windows.


=== Mac OS X ===

(TODO)


=== Sandboxing ===

Many sandbox systems have problems, such as:

* Assumes all text is Unicode.

* Cannot request a command to use with popen (or from configuration files).

* When asking for a file, cannot also include certain other files whose
names are done by adding additional text onto the end of the name (this is
needed for SQLite to work, and also for non-composite puzzle sets in Free
Hero Mesh).

* Assumes a desktop environment.

Therefore, if it is to be used, a better one should be made up.

  created, destroyed, or moved. It still receives broadcast messages
  normally, and can also be addressed specifically.

(CollisionLayers <userflags...>)
  Define user flags as CollisionLayers bits; the first defined flag is
  bit0. Up to 8 flags can be defined in this way.

(Density <numbers...>)
  Define the default Density settings for classes that use the collision
  layers. Each number must be in range 1 to 255, and there cannot be more
  than eight density numbers defined. Their order is the same as the order
  of the user flags in the (CollisionLayers) block.

(InputXY <options...>)
  Enables coordinate input. Currently there are no options, so the options
  must be left blank. See the documentation about the CLICK message for
  more details about coordinate input.

(LevelTable <definitions...>)
  Define the level table. See the section about level table definition
