hello frnds i m very new to scripting ! so need ur help can u plz make me understand what is GetComponent ? sorry m not too tecnical so make me understand as easily as possible ! it would b better if u give an example ! thanks !
GetComponent is one of the most aptly-named internal functions, in that it does exactly what the name of the method says. When you call
GetComponent<Animation>();
it finds the first component on that gameObject of type ‘Animation’ and returns that. If there is no such component it returns ‘null’ (nothing).
If you have an object with two scripts on it: ‘MovementScript’, ‘AnimationScript’ and you want the animation script to have behaviour that depends on the MovementScript, you can access it like this:
MovementScript movement;
void Start(){
// GetComponent cannot be called from field initialisers!
movement = GetComponent<MovementScript>();
}
Then, anywhere else in the script where you need to look at the ‘movement’ component, you can just refer to that property (since it has been set up in Start).
