How to make an if command that ignores code?

for example, If (player.rigidbody2D.transform.position.x = 1)

ignore (code)

just use the //.

like

// (player.rigidbody2D.transform.position.x = 1)

if you mean, that it should stop doing more.

use break;

You also have else.

if(someCondition){
    // do something
} else {
    // do something different
}

Note the is equal to symbol is ==. A single = is an assignment call, ie make this equal to something else.

Based on your example, you can write:

if (player.rigidbody2D.transform.position.x == 1) {

  // do nothing (ignore)

} else {

  // do something

}

or, you can write:

if (player.rigidbody2D.transform.position.x != 1) {

  // do something

} else {

  // do nothing (ignore)

}
