# DotFilters
Methods to handle DotFilters. Dot filters are filters that filter in or out ERSMinimapDots.

(TRSDotFilter)=
## type TRSDotFilter
```pascal
TRSDotFilter = record
  Bounds: TPointArray;
  Circle: TCircle;
  Inside: Boolean;

  Timeout: Boolean;
  Timer: TCountDown;
end;
```
Type used to filter minimap dots.


- - -

## TRSDotFilter.Create
```pascal
function TRSDotFilter.Create(bounds: TPointArray; c: TCircle; inside: Boolean; time: Int32 = -1): TRSDotFilter; static;
```
Static method to create a TRSDotFilter.


- - -

## TRSDotFilter.IsExpired
```pascal
function TRSDotFilter.IsExpired(): Boolean;
```
Checks if a TRSDotFilter is already expired by checking it's timer.


- - -

## TRSDotFilter.IsValid
```pascal
function TRSDotFilter.IsValid(p: TPoint): Boolean;
```
Checks if a point is valid accordint to the current TRSDotFilter;


- - -

## TRSDotFilter.Draw
```pascal
procedure TRSDotFilter.Draw(out bitmap: TMufasaBitmap);
```
Internal method to draw the current dot filter on a bitmap for debugging.
You can see this in action by calling `Debug(TRSDotFilter)`.


- - -

(TRSDotFilterArray)=
## type TRSDotFilterArray
Type used to manage and interact with arrays of TRSDotFilters.


- - -

## TRSDotFilterArray.Setup
```pascal
procedure TRSDotFilterArray.Setup(bounds: TPointArray; circle: TCircle; inside: Boolean; time: Int32 = -1);
procedure TRSDotFilterArray.SetupBounds(bounds: TPointArray; inside: Boolean; time: Int32 = -1);
procedure TRSDotFilterArray.SetupCircle(circle: TCircle; inside: Boolean; time: Int32 = -1);
```
Creates and adds a TRSDotFilter to the current TRSDotFilterArray.


- - -

## TRSDotFilterArray.ClearExpired
```pascal
procedure TRSDotFilterArray.ClearExpired();
```
Clears expired TRSDotFilter from the current TRSDotFilterArray.
You usually don't need to call this directly, but you can if you want.
Other methods already take care of this by default for you regardless.


- - -

## TRSDotFilterArray.IsValid
```pascal
function TRSDotFilterArray.IsValid(dot: TPoint; clearExpired: Boolean = True): Boolean;
```
Checks if a dot/point is valid in any of the TRSDotFilters in the current array.
By default, expired TRSDotFilters are cleared from the array while this runs.


- - -

## TRSDotFilterArray.FilterDots
```pascal
function TRSDotFilterArray.FilterDots(dots: TPointArray): TPointArray;
```
Filter the dots/points passed into this according to our current TRSDotFilters.


- - -

## TRSDotFilterArray.Draw
```pascal
procedure TRSDotFilterArray.Draw(out bitmap: TMufasaBitmap);
```
Internal method for drawing the TRSDotFilterArray on a bitmap for debugging.
You can see this in action by calling `Debug(TRSDotFilterArray)`


- - -

## TRSMinimap.GetFilteredDot
```pascal
function TRSMinimap.GetFilteredDotArray(dot: ERSMinimapDot; dotFilters: TRSDotFilterArray): TPointArray;
function TRSMinimap.GetFilteredDot(dot: ERSMinimapDot; dotFilters: TRSDotFilterArray): TPoint;
```
Retrieves and filters minimap dots according to the specified TRSDotFilters.


- - -

## Debug
```pascal
procedure Debug(filter: TRSDotFilter); overload;
procedure Debug(filterArray: TRSDotFilterArray); overload;
```
Debugs a TRSDotFilter or TRSDotFilterArray on the client.
