Can't access transform rotation from script

[haganenno]

void Update()
{
    transform.Translate(0f, movSpeed * Time.deltaTime, 0f);
    if (Input.GetMouseButtonDown(0))
    {
        Debug.Log("click");
    }
    if (transform.localRotation.eulerAngles.z == -45)
        Debug.Log("rotated");
}

in the inspector my rotation on z is set to -45, nothing logs in the console, tried making a GameObject variable, didn’t work, tried putting this.transform, didn’t work, doesn’t matter if it’s -45 or -45f, it just doesn’t work

What exactly are you attempting here??

@haganenno

if (transform.localRotation.eulerAngles.z == -45)

The above expression will almost guaranteed NEVER be true. Here’s why:

Floating (float) point imprecision:

Never test floating point (float) quantities for equality / inequality. Here’s why:

Debug.Log(2000.0f * 000.1f); is 200

Now that you have had your coffee, don’t forget about floating point imprecision: // @kurtdekker: don't forget about floating point imprecision using UnityEngine; public class FloatingPointImprecision : MonoBehaviour { void Start () { float a = 2000.0f; float b = 0.1f; float product = (a * b); float answer = 200; Debug.Log( "a = " + a); Debug.Log( "b = " + b); Debug.Log( "product of a*b = " + product); Debug.Log( "answer =…

Why Doesn't This Code Work?

This will explain it all. In an IEEE single-floating point number you can represent certain numbers perfectly and unambiguously. For instance, 0.5f is precisely represented as 0x3f000000 However, 0.1f CANNOT be precisely represented. One possible approximate representation is 0x3DCCCCCD The analogy is that you cannot show 1/3rd precisely as a decimal. 0.33 is correct to 2 decimal places 0.3333 is correct to 4 places etc. But you can never exactly represent 1/3rd as a decimal numeral.

Furthermore, reading Euler angles back from a transform is almost ALWAYS a disaster, or at least a complexity you don’t want. More reading:
