Code Explanation
The purpose of this code is to flip the player's sprite based on the direction they're moving.
When the player moves to the right, the sprite faces right, and when they move to the left, the sprite is flipped to face left.
This ensures the player’s animation always faces the correct direction while moving.
The sign(PlayerCollision.Platform.VectorX) determines the direction of the player's movement.
The sprite's width is either kept normal or flipped to make sure the player is always facing the correct way.

sign(PlayerCollision.Platform.VectorX)
sign(PlayerCollision.Platform.VectorX)
PlayerCollision.Platform.VectorX: This is likely the horizontal velocity (or movement vector) of the player on the platform. It tells you whether the player is moving left or right.
sign(): The sign() function returns:
1 if the value is positive (meaning the player is moving to the right),
-1 if the value is negative (meaning the player is moving to the left),
0 if the value is zero (meaning no horizontal movement).
Self.ImageWidth
Self.ImageWidth
This refers to the width of the player's sprite (or animation image).
sign(PlayerCollision.Platform.VectorX) * Self.ImageWidth
sign(PlayerCollision.Platform.VectorX) * Self.ImageWidth
This line of code multiplies the sign of the player's horizontal movement by the player's sprite width. Essentially, it adjusts the scale of the player's sprite along the X-axis:
If the player is moving to the right (positive velocity), the sprite’s width is multiplied by 1, keeping it at its normal orientation.
If the player is moving to the left (negative velocity), the sprite’s width is multiplied by -1, flipping the sprite horizontally.
