Unity Script Optimization

Scripts run every frame.

Inefficient code can quickly reduce performance.

Minimize work inside Update():

Example:

CSHARP

Transform playerTransform;

void Start()
{
    playerTransform = GetComponent<Transform>();
}

Avoid calling GetComponent repeatedly.

Instead of checking conditions every frame, use events to trigger actions.

Efficient scripting improves performance and scalability.

Optimize code early.

I'm always open to chatting about code optimization and scalable Unity architecture.
