extends RefCounted

|
## Validation utilities for Match3 gameplay
|
|
##
|
|
## Static methods for validating Match3 game state and data integrity.
|
|
## Prevents crashes by checking bounds, data structures, and game logic constraints.
|
|
##
|
|
## Usage:
|
|
## if Match3Validator.is_valid_grid_position(pos, grid_size):
|
|
## # Safe to access grid[pos.y][pos.x]
|
|
##
|
|
## if Match3Validator.validate_grid_integrity(grid, grid_size):
|
|
## # Grid structure is valid for game operations
|
|
|
|
|
|
static func is_valid_grid_position(pos: Vector2i, grid_size: Vector2i) -> bool:
|
|
## Check if the position is within the grid boundaries.
|
|
##
|
|
## Performs bounds checking to prevent index out of bounds errors.
|
|
##
|
|
## Args:
|
|
## pos: Grid position to validate (x, y coordinates)
|
|
## grid_size: Dimensions of the grid (width, height)
|
|
##
|
|
## Returns:
|
|
## bool: True if position is valid, False if out of bounds
|
|
return pos.x >= 0 and pos.y >= 0 and pos.x < grid_size.x and pos.y < grid_size.y
|
|
|
|
|
|
static func validate_grid_integrity(grid: Array, grid_size: Vector2i) -> bool:
|
|
## Verify that the grid array structure matches expected dimensions.
|
|
##
|
|
## Validates the grid's 2D array structure for safe game operations.
|
|
## Checks array types, dimensions, and structural consistency.
|
|
##
|
|
## Args:
|
|
## grid: The 2D array representing the game grid
|
|
## grid_size: Expected dimensions (width x height)
|
|
##
|
|
## Returns:
|
|
## bool: True if grid structure is valid, False if corrupted or malformed
