| memory | A pointer to the block of memory you want to free. Ensure this pointer is valid and was previously allocated using UnsafeUtility.Malloc to avoid undefined behavior. |
| allocator | The allocator type that was originally used to allocate the memory. It is crucial that the allocator matches the one used during allocation to ensure correct deallocation. |
Frees a block of memory that was previously allocated.
The Free method deallocates memory that was allocated using UnsafeUtility.Malloc. This is essential to prevent memory leaks, which can lead to reduced application performance or system instability. Always ensure that any allocated memory is freed when it is no longer needed.
Exercise caution when using this method. Improper deallocation of memory can result in undefined behavior and application crashes. The allocator used in this function should match the one used in the corresponding allocation.
