Position variable not updating
Hey everyone! I have recently noticed a very strange issue with the transform.position setter. When setting this in a LateUpdate function I have noticed immediately after setting a value it is not the desired value. Below is a small code snippet.
LateUpdate() {
transform.localScale = new Vector3(0f, 0f, 1f);
transform.position = new Vector3(0f, 0f, 0f);
if (transform.position.x != 0) {
Debug.LogError("No change at X position: "+transform.position.x);
}
}
In this snippet, the debug statement somehow get called. Does anyone have any idea why this may be occurring?
Directly comparing floats isn't a good idea. Ins$$anonymous$$d do something like if( |a-b| < someReallySmallValue). floating point representations can be slightly off.
I've tried your code snippet on Unity 4.2.0f4, and works all right on my end; no error being logged.
I forgot to mention that it is the child of a child of an object that is moving around and being scaled. I am adjusting values based on the new scale and then setting its position back to 0.
I believe it has to do with what Jerdak says, when the object is scaled inside another object the floating point precision can be off.
Make sure external scripts don't change this value. Check for subtle errors. For example == and = might be playing a trick on you, and instead of comparing the variables, you change them, etc
$$anonymous$$y lookAt function is not working because transform.position doesn't update. :(
