player objects disappear when moving forward

Unity Engine

Hi!

So I try to make my ball move but it keeps disappearing at times I recorded it so you guys can see what’s going on. How can I fix this issue?

Thank you in advance and happy easter!

Looks like it could be the y portion of the rotation and the z position.

Try starting the game, but don’t move like you normally do. In the inspector adjust the y rotation and see if it ever disappears. Then try the z position.

If one or both are the cause, make sure your code doesn’t do that. :slight_smile:

Post your code, if you get stuck, and maybe someone can help you further.

Okay, how exacly should I adjust the y rotation? to 0?

4

Well, what I originally meant was you may not want to be changing that in code? Though, yes, zero would be ‘unchanged’.

5

Okay! I haven’t changed anything in my code or in the z column where everything is set to 0 except for scale should it be set to 0 as well?

6

No, I don’t think the scale matters.

Note, there’s also the z position I mentioned before, though you haven’t commented on that. I’m fairly certain that was responsible for one of the “disappearing acts”, also.

7

Oh right! And I click the play button and changed the position in the Y rotation and z position and the ball did disappeared when I did that.

8

Ya… well, just make sure your code is not changing either of those? :wink:

9

It doesn’t!

10

How do they change while you’re playing then? :wink:

11

The code I’ve written for the ball to move doesn’t change at all when I test play it, only all the positions in the transform section change when I try to move the ball.

12

Hmm… Can you post the ball moving code?

public class NewPiskelkontrol : MonoBehaviour
   {
       void Update()
       {
        var x = Input.GetAxis("Horizontal") * Time.deltaTime * 150.0f;
        var z = Input.GetAxis("Vertical") * Time.deltaTime * 3.0f;


        transform.Rotate(0, x, 0);
        transform.Translate(0, 0, z);
       }



   }

Okay, so it is rotating and on the y and moving on the z…
That is code better suited for a 3d program, I would imagine.

For 2D, you’d want to move on the x-axis (in your scene). You can “rotate” your sprite left/right by using a negative/positive x-scale factor, or by using the ‘FlipX’ property.

If you’re just starting out, I’d suggest that you spend some time working on tutorials.

Thank you it worked! I was wondering I have a sun I want to make spining all the time how do I do that?

16

You can rotate 2D objects on the z-axis. Try it out :slight_smile:

17

I see thank you! Can I make so that it keeps spinning ingame? I guess I do it by making a script for it?

18

Yes, and yes :slight_smile:

Alright! Then I do like I did with my ball that I mark the sun and add component and choose script?

Sure, if it’s just rotating you can have the script just change the z rotation over time. :slight_smile:
