问题 I'm working on a game. At a certain point, I would like to create special GameObject. The special GameObject is called Projectile and is the same as GameObject but has a dx and dy as well as some other functions that only a projectile will have. I am trying to make Projectile extend the GameObject class, but I run into issues when I try to create an instance of Projectile. I've tried different ways of declaring Projectile and shuffling declaration order but can't seem to figure out why I'm

问题 So let's say I have a lua file, and at the top, I define a variable outside of any function, but I call it local local x = 1 Is there any difference between that local x, and a global x? 回答1: Yes, as it is local to the chunk that it is created in. Lua handles a chunk as the body of an anonymous function with a variable number of arguments (see §3.4.11). As such, chunks can define local variables, receive arguments, and return values. Moreover, such anonymous function is compiled as in the

问题 Is there any way to get several values from a function without creating variables for it? local major, minor, revision, codename = love.getVersion() -- Get current LÖVE version as a string. So instead of making four different variables (or array) we'll use something that will just return a value you need. get( love.getVersion(), 0 ) -- Will return the first value (major). I read somewhere that I can use square brackets and tried love.getVersion()[1] but it says "Attempt to index a number

问题 I have tried to add horizontal movement into my game in love, but I haven't found a way yet. This is my code. PADDLE_SPEED = 200 player1 = Paddle(10, 30, 5, 20) player1 = Paddle(10, 30, 5, 20) player2 = Paddle(VIRTUAL_WIDTH - 15, VIRTUAL_HEIGHT - 30, 5, 20) player3 = Paddle(30, 10, 20, 5) player4 = Paddle(VIRTUAL_WIDTH - 30, VIRTUAL_HEIGHT - 15, 20, 5) ball = Ball(VIRTUAL_WIDTH / 2 - 2, VIRTUAL_HEIGHT / 2 - 2, 4, 4) if love.keyboard.isDown('w') then player1.dy = -PADDLE_SPEED elseif love

问题 I am new to game development but I need to know if it is possible to create a save game feature in love2d with lua. 回答1: Sure. You can use a variety of libraries available. My current recommendation is Ser Binser ( Ser has been deprecated ). This process is called "table serialization." Then, you can do something like this to effectively create a "save." local ser = require 'Path.to.ser' local save function love.load() if love.filesystem.exists( 'Save.lua' ) then save = love.filesystem.load(

问题 Good whatever time of day! I have some sprite: A point has coordinates Actor.x; Actor.y . AB length = 96 BC length = 86 AC length = 42 All calculations are approximate, I made it with help the ruler in Photoshop. Sprite always towards mouse, angle (in radians) stores in Actor.direction variable. I draw sprite with scale 0.3 . All bullets toward mouse (that is Bullet.direction == Actor.direction ). I need to create bullets in the B point. How I can calculate coordinates of the B point with any

问题 I'm writing a little game for visual deficient people, but I'm having a hard time getting the mouse position. Let me explain : I need to know where in the table the mouse cursor is, without having a click, and then I want to play a sound. That sound would be different for every position. Any thoughts? Thanks, in advance! e.g., when the mouse is on the 1st box would be played the audio "a1", when it's on the 2nd box, "a2", and so on. I tried with: mouse_x, mouse_y = get_Position() if mouse_x
