我正在尝试制作这个 "fps" 游戏，但出于某种原因，mouseClicked 功能无法正常工作

Question

当我出于某种原因尝试执行此代码时，这部分代码：(RX1 = random x 1, RY1 = random y 1)（“+50 部分在那里，因为矩形的宽度为 50）

if(mouseClicked && mouseX > RX1 && mouseX < RX1 + 50 && mouseY > RY1 && mouseY < RY1 + 50){
    fill(0, 0, 0);
    rect(RX1, RY1, 50, 50);
}

不起作用，程序只是忽略它，我把它放在我能想到的任何地方，非常感谢有人的帮助，谢谢！

Here is the direct link to it

这是剩余的代码，以备不时之需（除了 if mouseclicked 部分之外的所有内容都有效

//random x and y variables for targets
var RX1 = random(25, 375);
var RX2 = random(25, 375);
var RX3 = random(25, 375);
var RX4 = random(25, 375);
var RY1 = random(25, 375);
var RY2 = random(25, 375);
var RY3 = random(25, 375);
var RY4 = random(25, 375);

    //the juicy stuff
    
    draw = function() {
         //coloring
     
      background(255, 255, 255);
        fill(255, 0, 0);
     
     //targets:

        rect(RX1, RY1, 50, 50);
        rect(RX2, RY2, 50, 50);
        rect(RX3, RY3, 50, 50);
        rect(RX4, RY4, 50, 50);
 
 //gun
 fill(0, 0, 0);
 
//front sight
    rect(mouseX - 5, mouseY, 10, 20);
    fill(255, 255, 255);
    ellipse(mouseX + 0.5, mouseY + 5, 5, 5);
    fill(0, 0, 0);
 //back sights
 rect(mouseX + 10, mouseY, 20, 20);
 rect(mouseX - 30, mouseY, 20, 20);
 
 //slide
 rect(mouseX - 35, mouseY + 20, 70, 50);
 
 //grip ledge
 fill(77, 77, 77);
 rect(mouseX - 35, mouseY + 71, 70, 20);
 fill(0, 0, 0);
 
 //grip
 rect(mouseX - 30, mouseY + 90, 60, 100);
 

};
//on mouse click/during shooting
    if(mouseClicked && mouseX > RX1 && mouseX <       RX1 + 50 && mouseY > RY1 && mouseY < RY1 + 50     ){
    fill(0, 0, 0);
    rect(RX1, RY1, 50, 50);
}

P.S。我知道我只为一个矩形制作了最后一个片段，没有一个可以以任何方式工作

我想我已经让程序响应鼠标点击。问题似乎是您检查鼠标单击的 if 语句不在 draw 函数之外，该函数永远循环，因此它从不检查 if 语句。我尝试将该 if 语句放在 mousePressed 函数中（无论您在代码中的什么位置，它都会在单击鼠标时被调用），它现在似乎可以工作（或者至少它在 if 语句中执行代码）：

//variables

//random x and y variables for targets
var RX1 = random(25, 375);
var RX2 = random(25, 375);
var RX3 = random(25, 375);
var RX4 = random(25, 375);
var RY1 = random(25, 375);
var RY2 = random(25, 375);
var RY3 = random(25, 375);
var RY4 = random(25, 375);

//the juicy stuff

draw = function() {
     //coloring
     
      background(255, 255, 255);
        fill(255, 0, 0);
     
     //targets:

        rect(RX1, RY1, 50, 50);
        rect(RX2, RY2, 50, 50);
        rect(RX3, RY3, 50, 50);
        rect(RX4, RY4, 50, 50);
     
     //gun
     fill(0, 0, 0);
     
    //front sight
        rect(mouseX - 5, mouseY, 10, 20);
        fill(255, 255, 255);
        ellipse(mouseX + 0.5, mouseY + 5, 5, 5);
        fill(0, 0, 0);
     //back sights
     rect(mouseX + 10, mouseY, 20, 20);
     rect(mouseX - 30, mouseY, 20, 20);
     
     //slide
     rect(mouseX - 35, mouseY + 20, 70, 50);
     
     //grip ledge
     fill(77, 77, 77);
     rect(mouseX - 35, mouseY + 71, 70, 20);
     fill(0, 0, 0);
     
     //grip
     rect(mouseX - 30, mouseY + 90, 60, 100);
     
    
};
//on mouse click/during shooting
mousePressed = function() {
    if(mouseX > RX1 && mouseX < RX1 + 50 && mouseY > RY1 && mouseY < RY1 + 50){
    fill(0, 0, 0);
    rect(RX1, RY1, 50, 50);
}
};
