Can i use raycast for something like a keypad?

Question

In my game i got a keypad next to a door and i got a raycast on my Player camera, how would i tell the game that the player hit a button? I have an idea how to tell the game if a code for the door is right but i dont know how to tell the game that the raycast hit the particular object. Prob something like this ..
public string input;
private string Code = "1234";

void checkRaycast(){
if(raycast hit the button1){
input = input + 1;
}
if(raycast hit the button2){
input = input + 2;
}
if....
}
..........................................
void CheckTheCode(){
if(input == Code){
UnlockDoor();
}

}

The checkRaycast method is my problem, thanks good people of the internet!

Answer 1

But is this considerd ok programming?

It's "ok" since it works, but it could be : simplified, optimized and more flexible:

Replace the code you have by the one below
Increase the size of keypadButtons array
Fill the "basic" information : TargetCollider, Animator, AnimationClipName
In the OnPress box, click on the "+" button, drag & drop the object holding the IdentifyObjectsScript script, and bind the correct functions to call (`AppendCode`, ClearCode, CheckCode)

Try and enjoy
