Rigidbody.drag not working well

Drag is only gonna have so much effect when you are constantly adding force

3

Is there any way slow down a normal addforce

4

You could increase drag. why are you using 1 specifically?

5

Why not use velocity instead force? Also have you played with mass?

6

I have increase addforce but it will eventually stop which I do not want

7

I do not wish to use mass to make it complicated

8

I thought your problem was that the drag was not slowing down your object, but you don’t want it to stop either?

9

I tried a new solution to make it stop immediately and it works but how do I set it back to normal speed when it is not bulletinside

if(!bulletinside)
		{
			bulletSpd=50.0f;
			rigidbody.AddForce(transform.forward * bulletSpd);
		}
		
 		if(bulletinside)
		{
			if(freeze  !fastforward  !slow)
			{
				bulletSpd=0.0f;
				rigidbody.AddForce(transform.forward * bulletSpd);
				
			}
			else if(fastforward  !slow  !freeze)
			{
				bulletSpd= 2000.0f;
				rigidbody.AddForce(transform.forward * bulletSpd);
			}
			else if(slow  !fastforward  !freeze)
			{
				bulletSpd = 0.0f;
				bulletSpd= 0.05f;
//				rigidbody.drag += 0.5f;
////				Debug.Log (rigidbody.drag);
//				rigidbody.AddForce(transform.forward *= bulletSpd);
				
			}
//			else if(!slow  !fastforward  !freeze)
			else
			{
				bulletSpd=50.0f;
				rigidbody.AddForce(transform.forward * bulletSpd);
			}	
		}
	}

You can try changing the RB’s velocity directly (rigidbody.velocity). Save the value it had before ‘bulletinside’ and then restore after it’s not ‘bulletinside’ anymore.

I’m a bit curious here. What are you trying to achieve?

11

I am trying to achieve when hit by slow it will slowdown and when it is not being slow it will go back to it original speed,The problem I faced is bullet stuck halfway when being slowed and not regaining to it original speed when it is not being slowed

12

How do I go back to the original speed after slowing down.This is my current code and it is not going back to the original speed after slowing down.

void Update () 
	{
		this.transform.position += this.transform.forward * Time.deltaTime * normbulletspd;
		
		bulletinside = GetComponent<ObjectState>().inEffect;
		//slow = GetComponent<ObjectState>().slow;
		fastforward = GetComponent<ObjectState>().fast;
		freeze = GetComponent<ObjectState>().stop;
		
		if(!bulletinside)
		{
			this.transform.position += this.transform.forward * Time.deltaTime * normbulletspd;
		}
		
 		if(bulletinside)
		{
			if(freeze  !fastforward  !slow)
			{
				bulletSpd=0.0f;
				rigidbody.AddForce(transform.forward * bulletSpd);
				
			}
			else if(fastforward  !slow  !freeze)
			{
				bulletSpd= 2000.0f;
				rigidbody.AddForce(transform.forward * bulletSpd);
			}

			else if(slow)
			{
				SlowDown();
			}
			else 
			{
				bulletSpd = 100.0f;
				rigidbody.AddForce(transform.forward * bulletSpd);
			}	
		}
	}
	
	public void SlowDown()
	{
		Debug.Log("SlowDown");
		normbulletspd = 1.0f;
	}
