Question

我真的不知道如何在Eclipse中正确使用相对路径。我在src文件夹旁边创建了一个res文件夹，里面有一个图像文件夹。

这是我目前的代码：

import os 
import random
import time
from utilities import roll


class Character(object):
    # A Class for ALL characters - player, enemy etc.
    def __init__(self, name, hp, armor, damage, strength,
                 intelligence, wisdom, dexterity, constitution, charisma,
                 inventory, profession):
        self.name = name
        self.hp = hp
        self.armor = armor
        self.damage = damage
        self.strength = strength
        self.intelligence = intelligence
        self.wisdom = wisdom
        self.dexterity = dexterity
        self.constitution = constitution
        self.charisma = charisma
        self.inventory = inventory
        self.profession = profession


class Player(Character):
    # A class for the Player character only.
    # We will use a few parameters to set initial variables
    def __init__(self):
        super().__init__(name="", hp=10, armor=10, damage=10, strength=7,
                         intelligence=7, wisdom=7, dexterity=7, constitution=7,
                         charisma=7, inventory=[], profession="")
    maxhp = 10
    level = 1
    exp = 0


class Enemy(Character):
    # a class for any enemy.
    def __init__(self):
        super().__init__(name=enemyname, hp=10, armor=10, damage=10,
                         strength=7, intelligence=7, wisdom=7, dexterity=7,
                         constitution=7, charisma=7, inventory=[],
                         profession="")

playerchar = Player()
# simply call playerchar rather than calling the Class each time


def menu():
                            # Running the Main Menu under a single Function.
                            # This is the simplest method of running the menu

        print("3. Quit")
        choice = input("\n>")
        if choice == 1 or choice == "start":
            gameloop()
        elif choice == 2 or choice == "settings":
            settings()
        elif choice == 3 or choice == "quit":
            break
        else:
            print("Please select an option from the menu.")


def settings():
    # Settings page for all amendments
    # TODO - create a 'settings' file and have this read/amend it?

    menu()

        playerchar.name = input(">")
        print("Well then, " + playerchar.name + ", let us begin.")
        statchoice()


def choosestat(statname, max, min):
    # Takes the name of the stat
    # as mentioned in the Player/Character class and
    # a min/max value for the length. Allows the player
    # to set their stats for the char.
    print("Your stat choices are: " + str(stats))
    choice = int(input("Please select a strength score ("+min+":"+max+")\n"))
    if type(choice) == int and choice < (max+1) and choice > (min-1):
        self.statname = stats[choice-1]
        stats.pop(choice-1)
    else:
        print("Please select a valid option.\n")

            # quick function to display all relevant stats in-line.

    choosestat(charisma, 1, 1)

    displaystats(playerchar)
    reroll = input("Do you wish to re-roll?")
    if reroll == "yes" or reroll == "y":
        statchoice()


menu()

Answer 1

尝试这样做

JButton addButton = new JButton(new ImageIcon(getClass().getResource("images\button.png")));

Answer 2

您可以使用getClass().getResource(...)创建一个图标，如下所示：

 Icon icon = new ImageIcon(getClass().getResource("/images/button.png"));
 JButton b = new JButton(icon);

Answer 3

Based on the forum无需写下 /res/image.png ，而只需写下 /image.png 即可。（顺便说一下，该图像位于src / main / resources文件夹中）

Answer 4

你可以这样写。

JButton addButton = new JButton(new ImageIcon("images/button.png"));

图像/图标使用相对路径
