User prompt
the ball currently has a flipping animation, that only flips the asset based on the ball's position relative to it's center. replace this animation to ensure this flipping happens once every second, regardless of the ball's position
User prompt
add a black outline to the score with a thickness of 10
User prompt
stretch the background over the entire screen
User prompt
add a background to the game that strecthes across the entire screen
User prompt
the score needs to remain at 0 until the platform starts moving, only start counting after the platform mvoes for the first time
User prompt
add +1 to the score once every second. only start counting after the player moves the platform, until then keep the score to 0
User prompt
add a score to the screen
User prompt
add a score to the game. it needs to start from 0. add +1 every second. only start adding +1 after the player moves the platform, until then keep the score 0
User prompt
make the rectangle invisible
User prompt
the ball rotates a bit too fast. maintain the same values for it's movement, but the rotation should not appear as fast
User prompt
the ball's rotation seems to not be working as intended. the ball should never rotate clockwise if the platform's middle is to the right of the ball's center, and viceversa
User prompt
Instead of using a global flag like `isBallFlipped`, use an instance-specific flag within each `Ball` class instance to track its animation state. This allows each ball to independently track its own animation state and flip at the correct intervals.
User prompt
:** The logic for flipping the ball's graphic every second should be moved into the `Ball` class's update method or a similar method within the class that gets called every tick. This way, the animation logic is directly tied to the ball instances and can properly access and manipulate the `ballGraphics` of each ball.
User prompt
The `ballGraphics` variable, which is intended to control the visual representation of the ball, should be properly associated with each instance of the `Ball` class. This means you should define and manipulate `ballGraphics` within the `Ball` class itself, rather than attempting to control it from the global scope. This ensures that each ball instance has its own `ballGraphics` that can be individually manipulated.
User prompt
fix it pls
User prompt
fix it
User prompt
the ball animation stopped working. it needs to have 2 frames, one regular and another one flipped, that change once every second
User prompt
Please fix the bug: 'ReferenceError: ballGraphics is not defined' in or related to this line: 'ballGraphics.scale.x *= -1; // Flip the ball' Line Number: 76
User prompt
the ball's flip animation got bugged, and changes based on the ball's relation to the platform. instead, it should simply flip once every second, regardless of it's position
User prompt
Consider creating a dedicated method for handling the animation logic that is separate from the update logic. This method can be called independently at the desired interval using `LK.setInterval` or similar timing functions provided by the game engine.
User prompt
If the ball animation relies on variables or flags (like `self.animationInitialized`), ensure these are accessible and correctly managed in the scope where they are used. This might involve moving some variables to a higher scope if necessary.
User prompt
Make sure that the `self.animationInitialized` flag is correctly set after the animation is initialized. This will prevent multiple initializations and ensure the animation setup is executed only once.
User prompt
Move the animation initialization logic outside of the update method to a more appropriate place, such as the constructor of the ball object or a dedicated initialization method that is called explicitly when the object is created. This ensures the animation is set up once and runs independently of the update logic.
User prompt
The condition `if (!self.animationInitialized)` is meant to ensure the animation setup runs only once. However, if there's any issue with how `self.animationInitialized` is set or if the update method doesn't run as expected (e.g., before the first flip occurs), the animation might not start at all. fix this
