2. Scripting Strategies

2.1 Cache Component References (cache component Reference)

Use rigidbody Rigidbody = getcomponent<rigidbody> instead of getcomponent<rigidbody> to reduce CPU overhead

2.2 Obtaining components using the fastest method (the fastest way to get a component)

Getcomponent (String), Getcomponent<componentname>,getcomponent (typeof (ComponentName))

Try to use getcomponent<componentname>

2.3 Removing empty callback declarations (remove empty callback declaration)

If you do not need to perform functions, remove the default start (), Update (), etc.
