Resolved Slightly Increase GameObject Scale While GameObject Is Constantly Shrinking

Hello,

I'm currently using the following script to gradually shrink the scale of the player (a sphere) in my game:

Code (CSharp):

1.   // Time it takes in seconds to shrink from starting scale to target scale.
2.   public float ShrinkDuration = 5f;
3.  
4.     // The target scale
5.     public Vector3 TargetScale = Vector3.one * .5f;
6.  
7.     // The starting scale
8.     Vector3 startScale;
9.  
10.     // T is our interpolant for our linear interpolation.
11.     float t = 0;
12.  
13.     void OnEnable()
14.     {
15.         startScale = transform.localScale;
16.  
17.         t = 0;
18.     }
19.  
20.     void Update()
21.     {
22.         t += Time.deltaTime / ShrinkDuration;
23.  
24.         Vector3 newScale = Vector3.Lerp(startScale, TargetScale, t);
25.         transform.localScale = newScale;
26.  
27.         if (t > 1)
28.         {
29.             enabled = false;
30.         }
31.     }

However, I also need to increase the scale of the player by a small amount every time it enters a certain trigger. Here is the code I currently have for doing so:

Code (CSharp):

1. private void OnTriggerEnter(Collider trig)
2.     {
3.         GameObject.Find("PlayerBody").transform.localScale += new Vector3(2, 2, 2);
4.     }

The problem I am having is that the script making the player grow only works when the script making the player gradually shrink is removed from the player or disabled. How would I make the player gradually shrink but also make the scale of the player increase slightly when it enters a certain trigger?

 

I would keep a separate float that starts at 1.0 and goes down periodically, and then when you hit your trigger, increase it.

Code (csharp):

1. private float MyScaleFloat = 1.0f;

Then use that float every frame to set the size:

Code (csharp):

1. playerTransform.localScale = Vector3.one * MyScaleFloat;

EDIT: looking at your code above, the shrinking code is producing fresh scales from your min to max scale. This is why growing doesn't work: you grown the .localScale and then it gets wiped out by the assignment from Lerp next frame.

I stand by my recommendation above: nothing in your code should do anything to scale, except that one assignment in my sample code. Everything else would hit the scale variable.

 

@Kurt-Dekker thanks for the help! I was eventually able to create a script using your suggestions to make the scaling work properly.
