Some themers expressed desire to have translucent themes. While the current AA stuff in uLandGraphics won't really allow this to work with LandBackTex properly, seems to me it should be safe to allow alpha for LandTex. Our LandTex should all have alpha of 255 on the existing themes.

unit uCursor;

interface

procedure init;
procedure resetPosition;
procedure updatePosition;
procedure handlePositionUpdate(x, y: LongInt);

implementation

uses SDLh, uVariables;

procedure init;
begin
    resetPosition();
end;

procedure resetPosition;
begin
    SDL_WarpMouse(cScreenWidth div 2, cScreenHeight div 2);
end;

procedure updatePosition;
var x, y: LongInt;
begin
    SDL_GetMouseState(@x, @y);

    if(x <> cScreenWidth div 2) or (y <> cScreenHeight div 2) then
    begin
        handlePositionUpdate(x - cScreenWidth div 2, y - cScreenHeight div 2);

        if cHasFocus then
            SDL_WarpMouse(cScreenWidth div 2, cScreenHeight div 2);
    end
end;

procedure handlePositionUpdate(x, y: LongInt);
begin
    CursorPoint.X:= CursorPoint.X + x;
    CursorPoint.Y:= CursorPoint.Y - y;
end;

end.
