java - Rectangle2D.contains() not properly detecting coordinates in boundaries -


i writing tower defense game intro cs2 class. have piece of code find next coordinate on map enemy unit:

  def findnextcoordinate(): (double, double) = {     val numaccessiblecoordinates = 8     val angle = 360 / numaccessiblecoordinates     val pixelsperframe = speed / maingame.fps //hypotenuse     val currentcoor = coordinates      def getaccessiblecoordinates(c: (double, double)): array[(double, double)] = {       val points = array.fill(numaccessiblecoordinates)((0.0, 0.0))        (i <- 0 until numaccessiblecoordinates) {         val currangle = angle *         val x = math.cos(currangle) * pixelsperframe         val y = math.sin(currangle) * pixelsperframe         points(i) = ((currentcoor._1 + x), (currentcoor._2 + y))       }       points     }      val accessiblepoints = getaccessiblecoordinates(coordinates)     var nextcoor = accessiblepoints(0)     var distfromfinish = coordinate.distancebetween(coordinates, maingame.finishcoordinates)      (pt <- accessiblepoints) {       val ptdistfromfinish = coordinate.distancebetween(pt, maingame.finishcoordinates)       var containstower = tower.containstower(pt)       println(containstower)       if (ptdistfromfinish <= distfromfinish && !containstower) {         nextcoor = pt         distfromfinish = ptdistfromfinish       }     }     nextcoor   }

"coordinates" variable stores coordinates given creep (this code snippet method in creep class).

the problem running collision detection. creep walk right through towers. (here tower.containstower method:)

def containstower(coor:(double,double)):boolean = {   var flag = false   (t <- maingame.towers) {     if (t.tower.contains(coor._1,coor._2)) flag = true   }   flag }

where t.tower java rectangle2d object. method returns true when creep walk through it, , yet i'm not getting desired effect of "blocking off" coordinate contains tower (rectangle2d) object.

can shed light why i'm getting behavior?

your default case go along x when there's no better option staying are. you'll run right tower default. should change default else, or use like

getaccessiblecoordinates.filternot( containstower ).minby{ pt =>   coordinate.distancebetween(pt, maingame.finishcoordinates) }

assuming there @ least 1 accessible coordinate.

by way, pathing not in general easy problem, , solution above tend leave oscillating solutions blocked creep run , forth between 2 closest spots. that's better running tower when other move take farther away are.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...

c++ - qgraphicsview horizontal scrolling always has a vertical delta -

Image
i've subclassed qgraphicsview custom canvas used in cad application. i've reimplemented qgraphicsview::wheelevent check keyboard modifiers control key and, if control key pressed, zoom. i'm trying implement horizontal scroll when user holds shift , uses wheel. the problem i'm having horizontal scrolling always scrolls 0.279. not huge problem, hugely annoying , points else being wrong. so, here questions: is right way implement horizontal scrolling? if not, is? how eliminate delta of 0.279? thanks in advance. code , sample output below void myview::zoom(int delta) { double factor = pow(1.2, delta/abs(delta)); this->scale(factor, factor); } void myview::scrollhorizontal(int level) { qpointf center = maptoscene(viewport()->rect().center()); qdebug() << "center: " << center.x() << ", " << center.y(); centeron(qpointf(center.x() - level, center.y())); } void myview::wheelevent(qwheeleve...
