处理未检测到死苍蝇

如何解决处理未检测到死苍蝇

潜伏了一段时间，第一次发帖:)

我目前正在为 uni 开发一个小游戏。我已经完成了大部分工作，但我遇到的“问题”是迷失在隧道视野中。我希望有人能够为我指明正确的方向。

我有一个程序（下面的代码）可以将苍蝇的图像打印到画布上。苍蝇拍跟随鼠标，当苍蝇在苍蝇拍的范围内并按下鼠标时，苍蝇会被击退。

我遇到的问题是程序仍将死蝇识别为具有碰撞检测功能，因此无论我单击活蝇的死蝇，仍会检测到碰撞并产生新的苍蝇。

任何帮助将不胜感激:) 谢谢！

PImage fly,flybye,swatter,swatted;
float[] fX,fY;  // fly locations array
float[] swat;  // fly swatted binary boolean array,1 = swatted,0 = not swatted
int score = 0;  // increments when swatted.

void setup(){
  size(800,400);
  fX = new float[0];
  fY = new float[0];
  swat = new float[0];
  fly = loadImage("fly.png");
  flybye = loadImage("flybye.png");
  swatter = loadImage("swatter.png");
  swatted = loadImage("swatted.png");
  
  fX = append(fX,random(1,800)); //first fly - random location
  fY = append(fY,400));
  swat = append(swat,0); // used as a boolean and matches to each individual fly,0 = fly not 
  swatted,1 = swatted.
}

void populate(){ // draw the flies in memory to the screen.
  for(int i = 0; i < fX.length; i++){
    if(swat[i] == 1){ // if swatted
      flybye.resize(30,30);// resize the fly image and place based on fx/fy array values
      image(flybye,fX[i],fY[i]);
    } else { // not swatted
      fly.resize(30,30);
      image(fly,fY[i]);
    }
    
  }
}

void collisionDetect(){ //collision detection - detect collision between swatter and fly
  for(int i = 0; i < swat.length; i++){ // bounding Box detection
    if(dist(fX[i],fY[i],mouseX,mouseY) < 50){ // condition should look at location of mouse 
                                                    and individual coordinates in fX and fY
      swat[i] = 1; // swatted
      fX = append(fX,800)); //new fly placed in random location when old fly dies.
      fY = append(fY,400));
      swat =append(swat,0); // new fly not swatted
      score++; //increment score
    }
  }
}

void draw(){ 
  background(255);
  populate(); // draw flys to screen.
  fill(0);
  textSize(20);
  text(score,5,20);// set a text size and location for the score.
  if(mousepressed) { // image swap
    collisionDetect();
    image(swatted,mouseX - 30,mouseY - 30);   //draw swatter image to around mouse locaiton - might want to play with this to get it to look right.
  }else{
    image(swatter,mouseY - 30); // if not pressed then alternative image.
  }
  
}

解决方法

难道你不应该在碰撞检测中测试苍蝇是否被拍打： $event->sheet->setCellValue($priceSummaryCell,'=SUM('.$priceSummaryCellFormula.')'); $styleFooterSummery = [ 'borders' => [ 'allBorders' => [ 'borderStyle' => \PhpOffice\PhpSpreadsheet\Style\Border::BORDER_DOUBLE,// BORDER_THICK BORDER_THIN 'color' => ['rgb' => '2f2f2f'] ],] ];
