In part 4 of this tutorial series we animated and prepared the enemy game objects. In this part we are going to make the enemies move, spawn them in the game and create the gameplay mechanism. The variables are self explanatory, the moveSpeed is going to determine how fast the enemy is moving and we are going to move the enemy with the help of Rigidbody2D component. When we test the game, you will see how all 3 enemy monsters are going to move to the right direction:. If you want to make the enemies move to the left side, just change the moveSpeed variable to a negative value. Next, open the EnemySpawner script and add the following lines of code below the class declaration:. Before we proceed further with the EnemySpawner script, attach the enemy prefabs in the enemyReference array variable in the Inspector tab:.

This is done by having an empty game object in the area. When player triggers the object it will create an enemy or multiple in specified or random places. Create an empty game object and choose box collider for it. Make sure that is trigger has checkmark so that player can pass it. Select your player tag that you have connected to the player to collide tag section and make it send spawn event. This state has random float action. Choose min and max values for the float and store it as float variable. If you want to randomize all the axes then create three actions that are stored as their own float variables. Second action for this state is set vector3 XYZ. Use your float values set with random float action and store it as vector3. In the next state you can spawn enemies with create object action. Choose your enemy prefab as the game object to be spawned and select position for it. If you randomize then choose your enemypos vector 3 value in the position. Timed spawn is literally spawning enemies after some amount of time has passed.

Inside the start method we can use GameObject. Unity Courses Ask.

Welcome welcome to this unity space shooter 2d tutorial. Where we will be building this cool new space shooter game with unity game engine. All the assets you will need already ship with unity. We will be using primitive sprites like triangles, circles and diamonds for our game. In this tutorial there is a lot to learn. We will learn about c scripts, UI, physics, quaternions, bullet spawning, enemy spawning, particle effects,post processing effects and score keeping. We use the c scripting to control our player or space ship movement, we build a enemy script spawner to help us spawn enemy ships. Another script will govern our bullets.

This is how the script is supposed to work:. But everytime I go to play mode, the enemies just keep piling up and lagging my game. About spawn before I can get out of play mode. Thanks for any help. It looks like you accidentally set up a recursive method in SpawnEnemy.

I was attempting to add some personal flare to the project by having enemies come from the top of the screen while facing sideways and shooting from the sides of the screen. Since we are going to remove enemy game objects from the game, we need a way to identify that we collided with the enemy objects, and for that we are going to use a tag. I already mentioned why we are performing that test in the lecture about the CameraFollow script, but I always like to revert back and explain the parts of code that are connected or have something to do with each other. Christopher Guyton. Now that we have a reference to the Rigidbody2D component, we can move the enemy using the FixedUpdate function:.

In part 4 of this tutorial series we animated and prepared the enemy game objects. In this part we are going to make the enemies move, spawn them in the game and create the gameplay mechanism.

If the Project Settings tab is floating dock it anywhere in the editor, and then select Physics 2D on the left side and scroll down until you see all the available layers that form a grid:. That would then be the value for each respective wave. Taha Mert Gokdemir. To make them face sideway, all you need is to change that to either 90 or or Your assignment is to make the moveSpeed a private variable inside the Enemy script and provide a way to edit the value of the variable so that we can randomize the speed of the enemy when it is spawned.
