Unity Memory Optimization

Low-end Android devices can have limited available memory.

Poor memory management can lead to:

Object Pooling

Use object pooling for frequently created objects such as:

This can reduce unnecessary Instantiate and Destroy operations.

Avoid creating unnecessary objects inside frequently executed methods such as:

Repeated allocations can eventually trigger garbage collection.

Instead of repeatedly searching for components, cache frequently used references.

private Rigidbody cachedRigidbody;

private void Awake()
{
    cachedRigidbody = GetComponent<Rigidbody>();
}

Review:

Use Unity's profiling tools to identify the actual cause of high memory usage.

Always test on real Android hardware because available memory can vary significantly between devices.
