![]() To create a Prefab just drag and drop the game object from the hierarchy window to the Project window. Prefabs are pre-defined game objects that we can use in our game. Once you create an Animation, you can see that Unity has added an Animator component to the game object. Follow the same steps to create Walk, Jump and Attack animations.Click on the Animation name and select create new.Set the time, so that the animation speed looks natural. Drag and drop all the idle sprites on to the Animation window.Select the sprite in the hierarchy window and click on create animation in the Animation window.Select one of the idle sprites and drag and drop it in the hierarchy window.This is not required but it will be helpful to manage things. Let’s shift the sprites required for Idle, attack, Walk and Jump to different folders. Make sure you segregate the sprites based on the animation. Now let’s create Animation from using the character sprites in the Sprite sheet. Once Download is complete now can click on Import to Import the assets into your project.Search for the assets that you found on Unity asset store and click download.In the Drop down on the top left select “My Assets”. We need to use the Package Manager to Import assets into our Unity project Select 2D template and give the project a name.Open up Unity Hub and Click on new Project.Now to Import the asset into Unity, we need to create a new Unity project. I found a Knight Sprite sheet with all animations and a 2D Platformer Winter for the platform. We will need one for the character and one for the Environment.Īfter a few Minutes of searching. So, let’s go to Unity Asset store and get some sprites. The First Thing that we will need are the sprites. We are going to investigate this process in more details later on but first let’s develop our problem for the AI.Importing Sprites and Sprite Sheet Getting the Sprites By doing so we ensure that our model will be able to generalize in the future under different circumstances. Once the agent becomes more proficient as solving a given task we need to slowly transition the mode of learning to Reinforcement Learning. The trick is to shift system’s attention on the demonstration in the beginning to a higher degree. ![]() With ML Agents we can easily enable the Imitation Learning through the configuration file. Furthermore, we can combine this technique with the Reinforcement Learning method to get even better results. The system will try to mimic moves from previously recorded session to learn faster. The human supervision over actions sequence means that we have a better control over what neural network actually learns. Instead of letting our AI to randomly select actions we can demonstrate, which ones it should be using. This is where the concept of Imitation Learning comes in. In addition, they need to occur in a specific order at the correct time! The concept of Imitation Learning All of a sudden we have a bunch of new activities that agent needs to carry out during a single episode. Now imagine a situation in which the AI needs to perform a specific sequence of actions in order to reach its goal. The agent has to select a single action of moving either left or right to find a treasure. The problem that we have given our enemy AI last time was relatively simple. That inevitably may lead not only to the extension of the training sessions but also the danger of less performant model. Secondly, it may take a long time for the agent to determine the right combination of actions to solve a task at hand. First, the agent randomly tries to apply different actions before it can receive a reward or penalty. ![]() There are two observations that we can make about this type of the training. The session results in an AI model that we can later use in the game. The Reinforcement Learning is based on teaching our agent how to solve a given task over time by rewarding or penalizing it for its actions. Last time we have built a solid foundation of implementing Deep Learning concept in our games. The limitations of Reinforcement Learning
