Spawn enemy unity 2d

Spawn enemy unity 2d 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. However, I am unsure of how to accomplish this.

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:.

For the wave system we created a new script and attached it to the spawn manager. Inside the start method we can use GameObject. Find to grab UI Manager script from the Canvas. We also need to get the Spawn Manager. Inside the Update method we check if the enemies left is less than or equal to zero and that the start of wave is equal false. We have a public method called start wave that sets the startOfWave true and starts the wave Coroutine. Then we wait 3 seconds and check if the enemies left are not equal to the enemies to spawn. If true, then we call the start spawning method on the Spawn Manager.

In the last state before destroying the object select ind add action and -1 for the enemy int variable.

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.

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. We use quaternions to control the rotation of our space ship around the center of our world. Particle effects for explosions and post processing effects to give us a bloom blur effect and spice up our flat shapes which unity give us.

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. You pass in the number to spawn and use that in your for loop, but then call SpawnEnemy with the same number within the for loop. This will just keep going forever. Rather than having your for loop inside SpawnEnemy, have it outside, and have the methods only spawn one at a time.

If you want to randomize all the axes then create three actions that are stored as their own float variables. Reading Time: 15 minutes. Sign me up. Range function, it will return a number between 0 and 3 not including 3, so it will return 0, 1, or 2. 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. If you want to make the enemies move to the left side, just change the moveSpeed variable to a negative value. In the next state you can spawn enemies with create object action. Youtube Instagram Facebook. You will notice that we are using Vector2 to add force to the velocity. 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:. Now that we prepared the enemies let us create a script that will move them. Range and we pass 0 and 2, which will return either 0 or 1 and we will use those values to determine if the enemy should be spawned to the left or the right side. Before you go:.

To make the game interesting, we are going to spawn enemies over and over in the game. Member-only story. Then link the second state back to the start state with finished event. You can do exactly that. If the number of enemies spawned is equal to the wave managers enemies to spawn variable, then we stop spawning, set the start of wave false, and reset the enemies spawned to zero. For the wave system we created a new script and attached it to the spawn manager. Text to speech. Build a Simple Minimap in Unity. Open the Enemy script and declare the following variables below the class declaration:. I appreciate the response! This means that we need to have some kind of time interval or a delay effect that we will use to spawn new enemies in the game.
