![]() Next, drag the Health Bar Border game object to the Health Bar game object to make it as its child, like below. Now, resize the Health Bar to the same size as the Health Bar Border. Next, with the Health Bar game object selected press T. Let’s rename this Empty game object to Health Bar The next thing that we’re going to do is to create an empty game object inside the Canvas so right-click on the Canvas game object and select Create Empty. Next, let’s rename our Image UI object to something like… Health Bar Border. This will resize the image based on the actual resolution of the image file. Next, just below the Preserve Aspect check box, click the Set Native Size button. Once the image is imported, go back to your hierarchy, select the Image UI object and navigate to its Image component and change its Source Image to the image that we have just imported. Make sure that once you have dragged the image onto your project files, you must change the import type to Sprite. Next, we’ll be changing the graphic being used in this object so download the PNG image provided below and import it to your project. Next, select your Image game object and make sure that it is placed right at the center of the canvas like below. With all that being said, select your Canvas game object and press F key to show the entire canvas on the screen. Inside the canvas, there will also be an image UI object created. This will be creating a new canvas especially if there’s currently none in the scene. To start, navigate to your hierarchy, right-click and select UI then Image. Now that we have our player health points set up, let’s begin working on displaying the actual health bar. So, if you take a look at the Update function, as you can see we’re checking if the Player hits the SPACE bar, if the player did, then the player will receive damage. Then, we also have the function that gives damages to the player. So in the code above, what we’re doing is we’re creating a set of functions that initialize the value of the current health of the player to the maximum. To start, we’re gonna need to create a new C# script and we’ll call it Health.cs. If the player currently has 50/100 health points then our health bar should calculate it based on that data and should display a half health bar. ![]() This is where we are going to base our health bar. Of course, before we can create the health bar we will need first to create the health points. If you have any sprites that you want to use for your player, feel free to use it. Then, look for Knob and select it like below. Once Sprite Renderer is added, navigate to it and click on the little circle beside the Sprite parameter. Next, click on the Add component button and look for Sprite Renderer using the search bar. Once created, select the Player game object and navigate to the Inspector window and reset the transform component like below. In our new scene, we’re going to create an empty game object and we’ll call it Player. If you have an existing project, feel free to use it for this lesson otherwise create a new project. In this tutorial, we’ll be guiding you on how to create a very simple health bar that you can EASILY apply to anything like player, enemy, objects or etc. On a serious note though, we’re very lucky that making a health bar is very easy to accomplish, special thanks to Unity for providing us game developers a UI system where we can easily modify each interface to display different kinds of things like Loading bar, power bar, time progress bar, etc. Speaking of MOBA, we’re very happy to announce that we’re having a partnership with Raid Sha- just kidding. There are moments that you will see the health bar placed at the top of the player’s character especially if the game is a MOBA or Multiplayer online battle arena. Of course, that’s not the only type of HUD that you will see in video games. If you’re not sure what it is, it’s the graphic that you see mostly at the top-left corner of the screen ( depends on the game). ![]() Most health bars are displayed using HUD or Heads-up Display. ![]() ( Yes, I know there are games that don’t use “health bars” but they still use health to kill players, you get the point.) Of course, if there’s no health in video games, then players will never lose. This is what it writes in the terminal: INFO:mlagents.One of the most common things that we see in video games is a health bar. Mlagents-learn config/trainer_config.yaml -load -run-id=Taxi-1 -train Then, I saw that you had to add -load to the command if you wanted it not to start over the whole training and to continue training your previous model. Then, I tried to train it again, with another In the terminal, but the ai stopped training after 50 000 steps. Mlagents-learn config/trainer_config.yaml -run-id=Taxi-1 -train Before, when I wanted to train my ai, I was writing Hi I am trying to do my first unity ml-agents ai.
