Now that we have successfully created a collectable coin and developed a counting system for it, we can take a look at other types of collectables that are commonly used in video games.
The first one is the Health Point; it is very common to see this type of collectable in multiple game genres and it allows us to have a health system–that way, we can get hit a few times before dying.
Let's start by downloading Health.unitypackage and importing it into your project. Now drag the Health prefab into the Hierarchy view so that we can take a look at it. If we press Play, we can see that it is a simple heart sprite that bounces up and down.
At this moment, nothing will happen if the character touches the heart, so the next thing that we need to do is code our Health prefab. Collectables generally have the same principles; they need to be collected, and if we think about it, Health Points behave just like the Coins. For that reason, we can start by duplicating the Collectable...
