How to re-size prefab in code

[wijesijp]

I have a prefab created by joining several cylinders using hinge joints. I can resize the prefab during design time to any value and it works perfectly in game.

I decide to resize the object in run time based on the screen resolution using following code.

void Awake()
{

	float  screenHeight = Screen.height/2;
		
	int scaleValue = (int)(screenHeight/160);
			
	gameObject.transform.localScale = new Vector3(scaleValue,scaleValue,scaleValue);
}

when i do that cylinders make up the prefab are not in the correct positions. But they are in correct positions if I re-size to the same value in editor.

Can anyone explain why this is happening?

HingeJoints mean rigidBody is happening? See if it scales properly without having rigidBody / Hinge?
Perhaps the physics are interfering with some cached data…
And if so… you may have to dynamically add rigidBody on runtime?
