Constant Summary collapse

ZENO_UNLIMITED =

Set zeno_level to this to turn off zeno checking.

VERSION = 
'1.3.29'
Infinity = 
Math::Infinity
Always = 
Transition.new :name => :Always, :guard => nil
Enter =

The asymmetry between these two states is that components in Enter are active in the continuous and discrete updates. Components in Exit do not evolve.

end

.with_library(&block) ⇒ Object

Defer a block until just after the library ruby code is loaded, but before commit. Necessary for defining inline C functions or shadow_attrs. Note that a whole require statement could be placed inside the with_library block.

def RedShift.with_library(&block) # :yields: library
  @library_calls << block
end

.worlds(world_class = World) ⇒ Object

Returns a list of all worlds (instances of RedShift::World and subclasses), or just those descending from world_class. Not very efficient, since it uses ObjectSpace.each_object, but useful in irb.
