By the end of this 2D Unity tutorial we'll have our little character shooting and damaging enemies with our ranged combat system.
I'll show you how to aim your gun towards the mouse cursor (using the new Input System,) how to rotate the gun after a certain degrees threshold, and how to rotate your bullets when they are spawned in (as well as how to rotate them towards your velocity direction!)
To make this more fun, I'll show you an easy way to setup TWO kinds of projectiles that you can shoot.
I cover a lot here, so we're going to go through this 2D shooting tutorial fast!

@meowl9329 Год назад

I love these! Would want to see you cover the system part, like game saving, data structure, handling multiple scenes etc.

@sasquatchbgames Год назад

thanks! Already had two of those on my future list ;)

Have you thought about doing a tutorial on the weapon system? Switching between weapons, maybe adding UI icons, etc.

@midniteoilsoftware Год назад

A much simpler solution for handling collisions is to just use the collision matrix in the physics settings. That negates the need for any code.

@midniteoilsoftware Год назад

A cool follow-up video would be how to use ScriptableObjects for bullet types.

@sasquatchbgames Год назад

I love scriptableObjects :D

@midniteoilsoftware Год назад

2 time-saving tips: edit the script template so it doesn’t include all the boiler plate code you always remove anyway and there is a setting under preferences to create objects at origin so you don’t need to reset the transform every time you create a new GameObject.

@sasquatchbgames Год назад

those are 2 things I've been procrastinating lol. Thanks for the tip, I'm going to have to do both of those

Hi there! Great tutorial as always. I've implemented this after doing the Hollowknight style camera tutorial which took a bit of figuring out as it effected the rotation of the gun (if anyone wants help just ask). The multiple cameras caused problems. I am trying to modify this to suit my game. I have an ability system with upgrades and have tried to add a multishot upgrade, but its a bit buggy at the moment, it shoots three bullets at once in an arc but the extra two just shoot sideways :( I used Quaternion.Euler in the Instanciation of the bullet to be able to change its y axis rotation but that hasn't worked. I'm also struggling with trying to flip the character when rotating the gun past 90/-90 degrees like the gun. The player movement and jumping is turned off and the attack ability is turned on as well as the gun when holding down the attack button. The player can flip when aiming past 90/-90 degrees like the gun however, when exiting the attack (Releasing attack button), if the player is facing left it messes up the flip function of the player so that he is facing the wrong way when moving. I'm sure ill figure it out, but if anyone has a good solution for flipping the character I'd appreciate the help!

Please update the lesson for perspective camera! It seems to mess up your code

@Teles0704 3 месяца назад

my bullet is being destroyed when it spanws, what can i do?

@CyberAngel67 Год назад

I would argue that as you are setting the transform right to the velocity it doesn't need to be done inside a FixedUpdate.

@sasquatchbgames Год назад

just gave it a shot in Update, and it produced weird janky movement. Definitely works best in FixedUpdate

@CyberAngel67 Год назад

@suzyeon4222 4 месяца назад

when I rotate, the gun rotates in the wrong direction. Please help

@suzyeon4222 4 месяца назад

i mean the sprite rotates in the right direction but when im facing left side it's the opposite direction. sorry my English is bad

@lancerdev2391 Месяц назад

@@suzyeon4222 Hi, I had the same problem and came up with a simple solution. Instead of flipping my player, I flip the sprite. Next, in my gun script, i modified this : float angle = Mathf.Atan2(dir.y, dir.x) * Mathf.Rad2Deg; Vector3 localScale = new Vector3(1f, 1f, 1f); Vector3 localPos = gun.transform.localPosition; if(angle > 90 || angle < -90) { localScale.y = -1f; localPos.x = -1f; } else { localScale.x = 1f; localPos.x = 1f; } gun.transform.localScale = localScale; gun.transform.localPosition = localPos; If flips the gun depending on the facing direction of the sprite of the player. Hope this helps !

At 5:45, you could have just used gun.transform.localEulerAngles.z instead of rotation. Correct me if I am wrong. In the end, you use interface and grab a reference to that instead of grabbing enemy script. The reason you say is because there are other objects that get destroyed by bullet. But, you wouldn't add enemy script on other objects. Right ?. So only enemy gets to have enemy script and you don't need an interface there. Really loved your video

@midniteoilsoftware Год назад

A more concise syntax is if (collision.gameObject.TryGetComponent(out var damageable)) …

@midniteoilsoftware Год назад

Cheaper than a null comparison

@sasquatchbgames Год назад

Thanks for the tip! I'm going to try that out
