Function Documentation

void GenerateWorld ( GenWorldMode  mode,
uint  size_x,
uint  size_y,
bool  reset_settings 
)

void GenerateWorldSetAbortCallback ( GWAbortProc proc  ) 

Set here the function, if any, that you want to be called when landscape generation is aborted.

Parameters:
proc callback procedure

Definition at line 209 of file genworld.cpp.

References GenWorldInfo::abortp.

Referenced by GenerateTerrainPerlin().

void GenerateWorldSetCallback ( GWDoneProc proc  ) 

Set here the function, if any, that you want to be called when landscape generation is done.

Parameters:
proc callback procedure

Definition at line 199 of file genworld.cpp.

References GenWorldInfo::proc.

void HandleGeneratingWorldAbortion (  ) 

Really handle the abortion, i.e.

clean up some of the mess

Definition at line 253 of file genworld.cpp.

References _switch_mode, GenWorldInfo::abortp, CleanupGeneration(), ThreadObject::Exit(), and GenWorldInfo::thread.

Referenced by _GenerateWorld().

void IncreaseGeneratingWorldProgress ( GenWorldProgress  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 1332 of file genworld_gui.cpp.

Referenced by _GenerateWorld(), GenerateLandscape(), GenerateTerrainPerlin(), GenerateTowns(), PlaceInitialIndustry(), and PlaceTreesRandomly().

bool IsGenerateWorldThreaded (  ) 

Tells if the world generation is done in a thread or not.

Returns:
the 'threaded' status

Definition at line 68 of file genworld.cpp.

References GenWorldInfo::quit_thread, and GenWorldInfo::threaded.

static bool IsGeneratingWorld (  )  [inline, static]

Check if we are currently in the process of generating a world.

Returns:
are we generating world?

Definition at line 74 of file genworld.h.

References _gw, and GenWorldInfo::active.

Referenced by DoCommandP(), DrawDirtyBlocks(), HandleAutoscroll(), HandleKeypress(), HandleMouseEvents(), HasRoadTypesAvail(), and StateGameLoop().

bool IsGeneratingWorldAborted (  ) 

Is the generation being aborted?

Returns:
the 'aborted' status

Definition at line 245 of file genworld.cpp.

References GenWorldInfo::abort.

void SetGeneratingWorldProgress ( GenWorldProgress  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.

Definition at line 1318 of file genworld_gui.cpp.

Referenced by _GenerateWorld(), GenerateIndustries(), GenerateLandscape(), GenerateTowns(), and GenerateTrees().

void WaitTillGeneratedWorld (  ) 

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

It will not continue till the work is done.
