THIS WORK
var tochka =Vector3(0,0.03,0);
if (transform.position==tochka){
audio.Play();}
else {audio.Stop();}
BUT I NEED THIS
if (transform.position>=tochka){
HOW TO DO IT?
Well, first off, the reason that the existing line works is because it makes sense to check if two vectors are equal. However, it doesn’t make complete sense to check it a vector is greater than or equal to another vector. What exactly are you trying to test for here? Are you trying to play a sound when this object is close to “tochka”?
If so, you need to get the distance between the vectors and check that distance. Hopefully that helps some!
