Minimap to Mainscreen¶
The core for our minimap to mainscreen projection. Supports rotation, and zoom, and resizable client.
MM2MS extends the Minimap interface as well as the mainscreen interface with functionality to convert coordinates to & from the minimap to the mainscreen.
MM2MS¶
type TMinimapToMS¶
type
TMinimapToMS = record
BASE_W, BASE_H: Int32; // the size of the area we project to (mainscreen size)
MSCX, MSCY: Int32; // the center of the area we project to (mainscreen center)
MMCX, MMCY: Int32; // the center of the area we project from (minimap center)
SCALE_MIN, SCALE_MAX: Double; // direct zoom (relates to BASE)
ZOOM: Double; // current zoom
YSHIFT: Double; // zooming may cause mid-Y to shift
end;
The comments explains it. This is the datastructure MM2MS uses.
MM2MS.Init¶
procedure TMinimapToMS.Init(Resizable: Boolean);
This method is called automatically once SRL loads. So you don’t have to deal with it.
This methods Init’s the MM2MS variable, sets up values needed for a succesful projection. MM2MS supports Resizable RS client, but SRL does not. This is added only for future-proofing.
MM2MS.Transform¶
function TMinimapToMS.Transform(coord: Vector3; matrix: TMatrix4): Vector3;
Transforms the given coordinate with the given transformation matrix matrix
MM2MS.Project¶
function TMinimapToMS.Project(Coords: Vector3Array; Rotation: Vector3): TPointArray;
Projects the given coordinates coords
and applys the given Rotation
vector to the projection.
MM2MS.Run¶
function TMinimapToMS.Run(Arr: Vector3Array; Roll:Single=$FFFF): TPointArray;
The method we actually call (internally) to project our coordinates from the minimap to the mainscreen.
MM2MS.SetZoom¶
function TMinimapToMS.SetZoom(ZoomLevel: Double): TPointArray;
If you are not playing at fully zoomed out you need to set the zoom-level for MM2MS to operate with.
The expected input is a value between 0
and 100
where 100
is fully zoomed out.
** Example **
MM2MS.SetZoom(Options.GetZoom());
The example sets the zoom to whatever level is set in the RS options.
Minimap¶
Extend the minimap-functionality with MM2MS functions
Minimap.ArrToMs¶
function TRSMinimap.ArrToMs(Arr: Vector3Array; Roll:Single=$FFFF): TPointArray; overload;
function TRSMinimap.ArrToMs(Arr: TPointArray; Roll:Single=$FFFF): TPointArray; overload;
Takes array of points on the minimap, returns mainscreen projected array of points. The first method takes a vector3 array as input, so we can pass height as well, and more detailed coordinates to scale.
Minimap.VecToMs¶
function TRSMinimap.VecToMs(Vec: Vector3; Roll:Single=$FFFF): TPoint;
Takes a single coordinate as a Vector3 on the minimap, and converts it to a point on the mainscreen.
ROLL is the compass angle, by leaving it default it will gather the compass angle itself.
Minimap.PointToMs¶
function TRSMinimap.PointToMs(PT: TPoint; Roll:Single=$FFFF): TPoint;
Takes a single coordinate as a TPoint on the minimap, and converts it to a point on the mainscreen.
ROLL is the compass angle, by leaving it default it will gather the compass angle itself.
Minimap.VecToMsRect¶
function TRSMinimap.VecToMsRect(Vec: Vector3; Roll:Single=$FFFF): TRectangle;
Takes a single coordinate as a Vector3 on the minimap, and converts it to a rectangle / tile on the mainscreen.
ROLL is the compass angle, by leaving it default it will gather the compass angle itself.
Minimap.PointToMsRect¶
function TRSMinimap.PointToMsRect(PT: TPoint; Roll:Single=$FFFF): TRectangle;
Takes a single coordinate as a TPoint on the minimap, and converts it to a rectangle / tile on the mainscreen.
ROLL is the compass angle, by leaving it default it will gather the compass angle itself.
Minimap.VecToMsBox¶
function TRSMinimap.VecToMsBox(Vec: Vector3; Roll:Single=$FFFF): TBox;
Takes a single coordinate as a Vector3 on the minimap, and converts it to a rough box on the mainscreen.
ROLL is the compass angle, by leaving it default it will gather the compass angle itself.
Minimap.VecToMsBox¶
function TRSMinimap.PointToMsBox(PT: TPoint; Roll:Single=$FFFF): TBox;
Takes a single coordinate as a TPoint on the minimap, and converts it to a rough box on the mainscreen.
ROLL is the compass angle, by leaving it default it will gather the compass angle itself.
Minimap.StaticToMsRect¶
function TRSMinimap.StaticToMsRect(StaticMMPoint: TPoint; Height:Int32=0): TRectangle;
Takes static minimap coordinate, rotates it to compass angle, and returns a rectangle on the mainscreen The static point is therefor gathered at north, and it will rotate it as expected.
Minimap.StaticToMs¶
function TRSMinimap.StaticToMs(StaticMMPoint: TPoint; Height:Int32=0): TPoint;
This is the same as the above, only that it returns a single point on the mainscreen.
Mainscreen¶
Extend the mainscreen-functionality with MS2MM function
Mainscreen.PointToMM¶
function TRSMainScreen.PointToMM(MS: TPoint; Height: Int32=0; Accuracy:Double=0.2): Vector3;
Takes a mainscreen point and converts it to a point on the minimap.
Returns a Vector3 which includes input height. Conversion to a TPoint if that’s what you need is simply done by calling .ToPoint on the result.
Example
WriteLn Mainscreen.PointToMM(Point(250,140), 2); // as a vector (more accurate)
WriteLn Mainscreen.PointToMM(Point(250,140), 2).ToPoint(); // as a TPoint (lost accuracy)
