绘制中的 Def mouseClicked() 不起作用，我该如何解决？

Question

I am making a dnd application for fun, the char class is what each character is, but I can't seem to get to work

I have tried commenting out sections of code, yet it seems to be a problem with the init function

This is my code:

global mouseY
global x
x = 0

chars =[]



def setup():
    global tsize 
    tsize = 50    


def draw():
    global x
    if x == 0:
        def mouseon(x,y,xs,ys):
            return(mouseX <= xs and mouseX >= x and mouseY <= ys and mouseY >= y)
        class char:
            def __init__(self, name, HP, img, CLASS, SIZE, id):
                self.xp = 0
                self.yp = 0
                self.SIZE = SIZE
                self.name = name
                self.HP = HP
                self.img = img
                self.CLASS = CLASS
                self.id = id
                self.Hover = False
                chars.append(self)

        dog = char("john", 100, "x.png", "archer", 50, 0)
        print("l") 
        x = 2

    else:
        fill(255)
        background(255)
        stroke(0)
        strokeWeight(1)
        for i in range(height/50):
            for j in range(width/50):
                rect(i*50,j*50,49.5,49.5)
        for i in chars:
            def mouseClicked():
                    if mouseon(i.xp,i.yp,i.xp+i.SIZE,i.yp+i.SIZE):
                        i.Hover = True
                        print('h')
                    else:
                        print("n")
                        i.Hover = False
            def mouseReleased():
                    print("o")
                    i.Hover = False
            if i.Hover:
                fill(0)
                rect(i.xp+1, i.yp+1, i.xp+i.SIZE+1, i.yp+i.SIZE+1)
            fill(0,255,0)
            strokeWeight(0)
            rect(i.xp, i.yp, i.xp+i.SIZE, i.yp+i.SIZE)

expected result: when I press the mouse, I should get h or n printed to the console, and when I release it, I should get o

Actual results: nothing

EDIT: to clarify,
Draw is called once every frame
setup once at the beginning
mouseClicked when the mouse is clicked
and mouseReleased when the mouse is released

Answer 1

okay, so I had to put the mouse clicked and released functions at the bottom and put the for loops in those, but it solved my problem

the updated code is

global mouseX
global mouseY
global x
x = 0

chars =[]


def setup():
    global tsize 
    tsize = 50    


def draw():
    global x
    if x == 0:
        global mouseon
        def mouseon(x,y,xs,ys):
            return(mouseX <= xs and mouseX >= x and mouseY <= ys and mouseY >= y)
        class char:
            def __init__(self, name, HP, img, CLASS, SIZE, id):
                self.xp = 0
                self.yp = 0
                self.SIZE = SIZE
                self.name = name
                self.HP = HP
                self.img = img
                self.CLASS = CLASS
                self.id = id
                self.Hover = False
                chars.append(self)

        dog = char("john", 100, "x.png", "archer", 50, 0)
        print("l") 
        x = 2

    else:
        fill(255)
        background(255)
        stroke(0)
        strokeWeight(1)
        for i in range(height/50):
            for j in range(width/50):
                rect(i*50,j*50,49.5,49.5)
        for i in chars:
            if i.Hover:
                fill(0)
                rect(i.xp+1, i.yp+1, i.xp+i.SIZE+1, i.yp+i.SIZE+1)
            fill(0,255,0)
            strokeWeight(0)
            rect(i.xp, i.yp, i.xp+i.SIZE, i.yp+i.SIZE)

def mouseClicked():
    for i in chars:
        if mouseon(i.xp,i.yp,i.xp+i.SIZE,i.yp+i.SIZE):
            i.Hover = True
            print('h')
        else:
            print("n")
            i.Hover = False
def mouseReleased():
    for i in chars:
            print("o")
            i.Hover = False
