void DrawCross (  UInt16    xpos, UInt16    ypos, UInt16    xsize, UInt16    ysize )

Draw all zones around the point that is being painted. Parameters: xpos  horizontal position ypos  vertical position xsize  the size on the x-axis ysize  the size on the y-axis Definition at line 149 of file drawing.c. References DrawFieldWithoutInit(), getMapHeight, getMapWidth, UIFinishDrawing(), UIInitDrawing(), and UInt16.

void DrawFieldWithoutInit (  UInt16    xpos, UInt16    ypos )

draw a field without initializing something. ONLY call this function if you make sure to call UIInitDrawing and UIFinishDrawing in the caller Also remember to call (Un)lockWorld (2 functions) This function will not try to draw outside the bounds of the current world, or the defined 'clipping region' Parameters: xpos  horizontal position ypos  vertical position Definition at line 177 of file drawing.c.

welem_t GetGraphicNumber (  UInt32    pos )

Get the graphic to use for the position in question. Parameters: pos  index into map array Returns: the graphic to paint at this location Definition at line 229 of file drawing.c. References getWorld(), IsPowerLine(), IsRail(), IsRoad(), IsWaterPipe(), UInt32, and welem_t. Referenced by BuildSomething(), and DrawFieldWithoutInit().
