EXPORT 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.

EXPORT void DrawField (  UInt16    xpos, UInt16    ypos )

Draw the field at the specified location. Parameters: xpos  horizontal position ypos  vertical position Definition at line 139 of file drawing.c.

EXPORT 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.

EXPORT void ScrollDisplay (  dirType    direction )

Scroll the map in the direction specified. Parameters: direction  the direction to scroll map in Definition at line 54 of file drawing.c. References dirType, dtDown, dtLeft, dtRight, dtUp, getMapHeight, getMapWidth, Int8, and UIScrollDisplay(). Referenced by doButtonEvent(), and MoveCursor().
