Using Case Switch for Balloon Ammo

[Sarai]

Since the amount of balloons the player can have at one time is small, I felt like it would be more interesting to have balloon sprites that go away to indicate ammo like the health in our viking village project. Everything seems set up fine but I can't seem to plug in the images in the inspector.

[Professor Watkins]

Are those balloons UI Images or UI RawImages?

[Sarai]

They're UI raw images. Could I just change:

public Image balloonIcon1;
public Image balloonIcon2;
public Image balloonIcon3;
public Image balloonIcon4;

to raw images or do raw images do something different?

[Professor Watkins]

Images ≠ Raw Images. The easiest thing to do (so you don't need to change your code) is to make sure your balloons are indeed images (and not RawImages) by making sure the import settings are Sprites.

Otherwise, in your code you need to change the type to RawImage (https://docs.unity3d.com/2018.3/Docu....RawImage.html).
