    I need help..... again.
    I've got two vector3s both showing y as 0.
    when i go to get just the y values of these vectors the second one(which comes from mouse to world pos) shows as a different number not the 0 it shows in the vector3.

    Anyone got any ideas on whats going on.

    Maybe you are getting confused by what 2.384186E-07 means. It means that value with the point shifted left by 7 places so "0.0000002384186" so pretty much zero.

    If you were to display this with two digits of precision it'd be "0.00".

    This is why you should never compare floats to zero too, you should compare them approximately using Mathf.Approximately etc.

    If you're outputtng strings to the console, you can state the format and include how many digits are shown etc.
