How can I move an object based on a global axis?

Question

Hello,

I 'm trying to make a flying- beetle game and I want my bugs to fall towards the ground when the die but I can't think/find out how to move them on global axis. I use accelerator input from android so my Y-Axis change on my player. So when it dies, it goes up or left / right. It's a pretty funny glitch to watch but ruins the reality of the game.

Any ideas on how to fix it?

Thanks In advance!!! : )

     void FixedUpdate()
     {
         if (currentHealth <= 0 &&  isDead == false)
         {
             isDead = true;
             BeetleAudio.PlayOneShot(BeetleDieing);
         }
 
             if (isDead)
                   Death();
     }    
     void Death()
     {
         anim.SetTrigger("Die");
         playerRB.isKinematic = true;
         fly_Movement.enabled = false;
         transform.Rotate(new Vector3(0, 0, 0) * Time.deltaTime);
 
         if (transform.position.y >0)                                        //Check if above ground before and while sink
         transform.Translate(new Vector3 (0, -fallingSpeed, 0) * Time.deltaTime);
         else
         transform.Translate(new Vector3(0, 0, 0));
       }

By delfault the Tranform.Translate method use local space. But there is a second optional parameter that allows you to choose the space like this :

 transform.Translate(new Vector3 (0, -fallingSpeed, 0) * Time.deltaTime ,Space.World);

What is the 'space.World' ??? Actually, I want to move an NPC in Global axes while rotating them in Local axes. How do I do that??? I tried this..

transform.Translate(new Vector3 (speed*Time.deltaTime, 0 , 0);

It doesn't work. Can you Help me? Thanks in advance.

There is several methods for rotating an object, if you want to apply a constant rotation you should use transform.Rotate();

example:

transform.Rotate(15,0,0)

explanation:

This rotates the transform along it's local X-axis by 15 degrees every frame.

Yes, Thank You. What I actually want to do is, rotate an object on the local axes. as you mentioned, I used " transform.Rotate(0,180,0);" I also want to move it forward. But for that I cant use local axes, because the axes are constantly rotating and the object won't neatly move forward on the same local axes. Hence I want to know how to move them on the global axes. Do you know, how to move on global axes? Thanks in advance.
