GENWORLD_REDRAW_TIMEOUT  Timeout between redraws.

Definition at line 14 of file genworld.h.

Enumerator:
GW_NEWGAME  Generate a map for a new game.
GW_EMPTY  Generate an empty map (sea-level).
GW_RANDOM  Generate a random map for SE.
GW_HEIGHTMAP  Generate a newgame from a heightmap.

Definition at line 24 of file genworld.h.

enum gwp_class

Enumerator:
GWP_MAP_INIT  Initialize/allocate the map, start economy.
GWP_LANDSCAPE  Create the landscape.
GWP_ROUGH_ROCKY  Make rough and rocky areas.
GWP_TOWN  Generate towns.
GWP_INDUSTRY  Generate industries.
GWP_UNMOVABLE  Generate unmovables (radio tower, light houses).
GWP_TREE  Generate trees.
GWP_GAME_INIT  Initialize the game.

Function Documentation

void GenerateWorld ( GenerateWorldMode  mode,
uint  size_x,
uint  size_y 
)

void HandleGeneratingWorldAbortion (  ) 

Really handle the abortion, i.e.

clean up some of the mess

Definition at line 238 of file genworld.cpp.

void IncreaseGeneratingWorldProgress ( gwp_class  cls  ) 

Increases the current stage of the world generation with one.

Parameters:
cls the current class we are in.
Warning: this function isn't clever. Don't go from class 4 to 3. Go upwards, always. Also, progress works if total is zero, total works if progress is zero.

Definition at line 1103 of file genworld_gui.cpp.

void SetGeneratingWorldProgress ( gwp_class  cls,
uint  total 
)

Set the total of a stage of the world generation.

Parameters:
cls the current class we are in.
total Set the total expected items for this class.
Warning: this function isn't clever. Don't go from class 4 to 3. Go upwards, always. Also, progress works if total is zero, total works if progress is zero.

void WaitTillGeneratedWorld (  ) 

This will wait for the thread to finish up his work.

It will not continue till the work is done.
