Unity Script Optimization

Scripts run every frame.

Inefficient code can quickly reduce performance.

Avoid Heavy Update Logic

Minimize work inside Update():

• Avoid unnecessary calculations
• Cache values instead of recomputing

Use Caching

Example:

Transform playerTransform;

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

Avoid calling GetComponent repeatedly.

Use Events Instead of Polling

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

Final Thoughts

Efficient scripting improves performance and scalability.

Optimize code early.
