Spawn enemy unity 2d

I spawn enemy unity 2d 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. Here is the script for spawning enemies:. GetEnemyPrefab icurrentWave.

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.

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. We also have a Public End Wave method that starts the End wave coroutine.

In the int compare action, spawn enemy unity 2d, choose your enemy as the variable and compare it to zero. Level Up Coding Thanks for being a part of our community! While we fixed the hugging problem between the enemies we have another problem which is when the enemies get to the edge of the level they fall down from the ground and they continue falling down as long as the game is running.

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.

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.

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.

Then we wait 3 seconds and check if the enemies left are not equal to the enemies to spawn. For the randomSide we also use Random. 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. Next we spawn a random enemy using the Instantiate function and the randomly generated index and store the new spawned enemy in the spawnedEnemy variable. In the int compare action, choose your enemy as the variable and compare it to zero. 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:. You can do exactly that. Now when the player or any of the enemy game objects collides with the collector object it will be destroyed and removed from the game. Timed spawn is literally spawning enemies after some amount of time has passed. You can also use random wait and choose timespan for it. Subscribe Subscribed. See all from Christopher Adams.

We know that in Unity, the left side is the negative side, that is why we set the speed to a negative value, and you can easily test this out by setting a positive value for the moveSpeed variable. Because this is a 2D game, we can add force on the X and on the Y axis. Choose min and max values for the float and store it as float variable. In this part we are going to make the enemies move, spawn them in the game and create the gameplay mechanism. That makes sense to me an I appreciate it! Then link the second state back to the start state with finished event. For the enemy you need to have FSM for its death. Create object will create your enemy prefab in the position you want to. You can also randomize position for the enemies. Also attach the Left and Right game object in the appropriate slot in the EnemySpawner script:.
