# add several types of cloud generators
# timed entry (around 2000 turns), also for Sewer

# Gameplay: 

# Using this function will turn any ^ glyph on the map into a fog generator
# of the following kind:
#{{
#function place_vapours()
#subst("^ = lua:fog_machine{ pow_max = 20, delay_min = 50, delay_max = 300, size = 12, #start_clouds = 1, cloud_type = "freezing vapour"} ")
#end
#}}

# Using this function will turn any ^ glyph on the map into a fog generator.
# Any use requires two parameters as follows:
# : place_fog(_G, "freezing vapour", 200)
{{
function place_fog(e, type, strength)
   e.lua_marker(".", fog_machine { pow_max = strength, cloud_type = type,
                     delay_min = 50, delay_max = 300, size = 12, 
                     start_clouds = 1 } )
end
}}

# lacking possible random fog generators
