[@aroctagames4175]

for those who are having the issue where it only fires one direction, I figured out that it happens because of how you turn the player. if you follow the brackeys tutorials he has a guide for a 2d character controller but in a later video he changes how it is done for this exact reason. Most everything here still works but in the charactercontroller2D you need to change how you flip the player to "transform.Rotate(0f, 180f, 0f);" without the "quotes" and back in the projectile behavior script all you need is to change it to this " transform.position += transform.right * Time.deltaTime * Speed;" again without the "quotes" what is causing the problem is with scaling the sprite to change where you are facing the fix mentioned above is to make the sprite rotate rather than scale differently. because with scaling the lauchoffset stays looking to the right and will always think you are facing that direction and fire one way, but if you rotate the player parent object (change above) the lauchoffset will rotate with it, hope that helps

[@DistortedPixelStudios]

You do know that I show how to do this later in the video right?

[@aroctagames4175]

@@DistortedPixelStudios no I just found this video today and had the problem and then found a way to fix it. Most videos I've found dont have any sort of follow up with these problems so since I didnt see any comment about it I didnt even consider it

[@gamoe]

thanks you

[@Lilyvex]

Great tutorial! For some reason the projectile only moves right, regardless of which way the player is facing. Would love some pointers to this problem!

[@ruizon6899]

For some reason whenever i shoot on the right i cant see it in the game and scene view but when i played it in 3d whenever i shoot to the right the projectile spawns behind the camera thats why i couldnt see it so i just moved the camera back so i can see it Why does it spawn behind the camera?

[@RazgyMicYt]

Thanks man this really helped me couse i am really into it and i'm working to a game and your tutorials really helped me. I really want to ask something. Can you please make a tutorial like how to pick up items like score u now how it is in Mario you pick up a coin and it gives you that coin if you can do that it will be really helpful for 2d btw couse from all the tutorials i watched yours were the most helpful and good couse you are going straight to the thing that you are showing in the video and usually almost no KZbin does that

[@unitynocode]

Thank you ! I tried more than 10 examples from Google. But only your code working.

[@Huy-G-Le]

I have this problem, where: 1# I press the left mouse one, and three projectile spawn. 2# The projectile stay in the same spot, they won't fly any further. 3# The projectile only appears at one side, the right side and not the left side. How do I fix this? Also I'm using a different Player Movement Script, doesn't seem to raise any confliction though.

[@bobsanders5232]

First off this is an absolutely great video, and I'm keeping it for later, but in case there's anyone else who had the problem where the bullet spawned but didn't move forward at all the solution is in ProjectileBehavior replace the lines 6 to 10 with; public RigidBody2D _rigidBody //drag your the Projectile RigidBody2D into the _rigidBody box that'll be created under the script in the Projectile prefab inspector void Start() { _rigidBody.velocity = transform.right * Speed } I don't know why it didn't work for me and I don't see anyone else in the comments with this problem but... you can never be too sure, Cheers folks!

[@MiguelRodriguez-ff9wl]

my issue was the bullet travels faster when the player is moving, but the bullet travels slower when the player is idle, however your solution was better for me anyways so thanks for that however you want to include Time.deltaTIme somewhere in there,

[@egemen5404]

OnCollisionEnter2D not working properly. When i was type "private void OnCollisionEnter2D" it looks like as a simple method. Does anyone know the solution?

[@DieDona]

One question, does the projectile really need a rigid body, since you are moving it with the transform?

[@dragonballz3686]

Bro, I am making a 2d top down space shooter. There is a problem in shooting system, that is , when enemy is shooting and I shoot, then the player's bullet is colliding with enemy bullet and the player's bullet is destroyed but the enemies bullet is not destroyed. Can you tell me what to do to make the both bullets passing away without any collision.

[@Fwsr.]

to what button is the fire button assigned? it gives an error that i havent did that yet

[@seb56137]

I'm getting an error where it says the namespace ProjectileBehaviour couldn't be found. I've made sure to spell it right and everything

[@dantheace8538]

I wrote my script for the enemies projectiles and it worked flawlessly, but when I copy paste it to my player's the projectile just fly right through the enemy ?? The script for the enemies can kill my player but my player's script can't, even tho it's a copy paste from the enemies ?

[@erwanan5971]

Im having trouble with manipulating the empty objects with my mouse, I dont know but it seems like Unity doesnt let me drag it

[@rendericu92]

I have a strange issue here. When facing right, it shoots right but when facing left, the projectiles still go right and collide with the player

[@aroctagames4175]

i posted a fix here its a lot to retype out but just look at that comment if you still need help

[@MiguelRodriguez-ff9wl]

This worked for me however the bullet travels way faster when the player is moving and shooting at the same time and the bullet travels slower when the player shoots while standing idle. To fix that, I set the rigidbody2d body type of the projectile prefab to kinematic and now it fires much better from the players move speed but now it totally ignores my collisions detections. Update: Just realized there a checkbox for use kinematic/static collisions when you have kinematic body type selected, I think this body type works best for this tutorial

[@MyMike004]

nice update and question did you run into the issue that OnCollisionEnter2D for the projectile is not firing off?

[@Uncrypt]

Can somebody paste me the ProjectileBehaviour Script im getting the same error over and over and its the simplist one i just dk how to debug it.

the projectile only moves to the left, what is wrong?

[@nintenerd7680]

hey been following your tutorial step by step. but after i programmed the prefabs then ran the game. the console would recognise the button click but it doesn't show the circle bullet image. do you have any idea why this could be?? EDIT: i got it shooting, however the objects are not destroying, could anyone in the comments or yourself can bring this to attention please??

[@MyMike004]

same here

[@ciprianpasca7738]

So i have this problem. When i jump and shoot, the projectile doesn't collide with anything. Also they dont destroy on impact.

[@letsgamingde420]

Have the same weird problem, it does work with the grenades, but with these it does not work

[@clementparrot4001]

If your bullet only moves in one direction, you're probably using localScale for flipping your player whereas in this video transform.rotate(0,180,0) is used for flipping. So, on your Flip method, just add at the end: LaunchOffset.transform.Rotate(0f, 180f, 0f); And when you instantiate your bullet, write : Instantiate(projectilePrefab, LaunchOffset.position, LaunchOffset.transform.rotation) All should work after that ;)

[@bluups8477]

Okay so in the script, i there's no Projectile prefab and launchoffset option, i dont know why cause i follow the tutorial exactly the same. Any ideas?

[@zeanelhamas5392]

why my projectile can't get out and why my character if i cilck left mouse button doing backward

[@alliocha0591]

It's because the projectile collide with your player . I change "transform.position += -transform.right * Time.deltaTime * Speed;" to "transform.position += transform.right * Time.deltaTime * Speed;" and it worked. But the projectile is shoot in my back ... I think the code to set sprite rotation is a bit messed up but i didn't find solution

When i put it in it says compile error if its out the projectile only shoots in one direction to the left and if i press d it doenst shoot to the right

Your Projectile collides with the player and gets destroyed. There are 2 ways of fixing that: Easy-Way: Move ur LaunchOffset Better-Way: in "OnCollisionEnter2D" add this: Character2DController charControl = collision.collider.GetComponent(); Character2DController player = charControl; if (!player) { Destroy(gameObject); ]
