Hey, I'm getting a visual bug where a sort of ghost line effect is seen during sprite movement (from a sprite sheet) whenever the sprite moves past / through its quad edge values.

I spent the night building an animation system that runs animations off of sprite sheets and noticed it and thought it was just my code, but then I tested it with a static, moving paddle and the same thing happens.

It's like there's an invisible grid of funny lines at each quad width / height interval that shows up on the sprite whenever it moves.

Hi, the direct source code is throwing an error on line 73. It says "bad argument, string expected, got no value", but clearly paddle_hit.wav is defined. The file exists, all is well.

But the error?

pls help me out

When you hit a brick with the ball, the particle effects are meant to have the same colour as the brick you just hit. For me, the particles are just plain white no matter the colour of the brick. Does anyone know what's wrong?

Whenever I start the game, the level is always 32. If I die or beat the level, it still says Level 32. Is there a way to fix this?

im having trouble with my game because i keep running into the error mentioned in the title, heres my playstate.lua code:
--[[
GD50
Breakout Remake

-- PlayState Class --

Author: Colton Ogden
[email protected]

Represents the state of the game in which we are actively playing;
player should control the paddle, with the ball actively bouncing between
the bricks, walls, and the paddle. If the ball goes below the paddle, then
the player should lose one point of health and be taken either to the Game
Over screen if at 0 health or the Serve screen otherwise.

]]

PlayState = Class{__includes = BaseState}

function PlayState:init()
self.paddle = Paddle()

-- initialize ball with skin #1; different skins = different sprites

23- self.ball = Ball(1) -- this is where the error occurs

-- give ball random starting velocity
self.ball.dx = math.random(-200, 200)
self.ball.dy = math.random(-50, -60)

-- give ball position in the center
self.ball.x = VIRTUAL_WIDTH / 2 - 4
self.ball.y = VIRTUAL_HEIGHT - 42

-- use the "static" createMap function to generate a bricks table
self.bricks = LevelMaker.createMap()

end

function PlayState:update(dt)
if self.paused then
if love.keyboard.wasPressed('space') then
self.paused = false
gSounds['pause']:play()
else
return
end
elseif love.keyboard.wasPressed('space') then
self.paused = true
gSounds['pause']:play()
return
end

-- update positions based on velocity
self.paddle:update(dt)
self.ball:update(dt)

if self.ball:collides(self.paddle) then
    -- reverse Y velocity if collision detected between paddle and ball
    self.ball.dy = -self.ball.dy
    gSounds['paddle-hit']:play()
end

-- detect collision across all bricks with the ball
for k, brick in pairs(self.bricks) do

    -- only check collision if we're in play
    if brick.inPlay and self.ball:collides(brick) then

        -- trigger the brick's hit function, which removes it from play
        brick:hit()
    end
end

if love.keyboard.wasPressed('escape') then
    love.event.quit()
end

end

function PlayState:render()
-- render bricks
for k, brick in pairs(self.bricks) do
brick:render()
end

self.paddle:render()
self.ball:render()

-- pause text, if paused
if self.paused then
    love.graphics.setFont(gFonts['large'])
    love.graphics.printf("PAUSED", 0, VIRTUAL_HEIGHT / 2 - 16, VIRTUAL_WIDTH, 'center')
end

end

any help would be appreciated, heres the traceback error too jic:
