Unity 2D Aim and Shoot at mouse position Tutorial

[@gab0thebab068]

Thank you for providing an explanation for each line instead of just telling us what to write!

[@jacksonkalvin1205]

Hey dude, I've been doing a bunch of your tutorials recently, and I just wanted to thank you. I was stuck for quite a while on my 2d platformer, and now I'm making a whole bunch of progress thanks to these videos!

[@duckman1824]

I searched up tutorials for a solution, because my Fireball wasn't moving until I noticed that I haven't set it to any speed value but then I saw how you made it. And Thank your for the tutorial so my fireball also turns to the mouse position!

[@Jaskier13]

Hey guys, for those of whom this does not seem to work, also ensure that your camera is set to orthographic and not perspective. I faced the same problem and struggled so you don't have to. So best of luck with your games, travellers!

Thank you so much for this tutorial it will be extremely helpful for developing the game I'm in the midst of working on

[@HylianLegend]

If you place your cursor behind the weapon and near/on the player the projectile doesn't shoot correctly. Do you know how to fix this possibly? Also, while moving (say right) and shooting the opposite direction (left) the bullet is somehow overtaken by the player, and doesn't properly fire.

[@maxn9022]

hey! if you dont really care about having the gun looking sprite visible, then you can just change the x in bulletTransform to 0

[@_arcadian._]

I have a bit of an issue with my rotation point. Since my character has a rotation flip because they walk, when the rotation goes to -1, my block starts to work opposite of the mouse. How can i make it so the rotation point references the Player rotation value? Thanks in advance

[@ratonotota1508]

I had the same issue but Because I had to flip the gun, you just need to make the rotation angle negative when the player is flipped if(playerisflipped = true { transform.rotation = Quaternion.Euler(0, 0, -rotAngle); } else { transform.rotation = Quaternion.Euler(0, 0, rotAngle); }

[@risinguppercot8414]

@@ratonotota1508 for me i had to change the x value to negative aswell as the rotation angle if (isFacingRight == false) { rotZ = Mathf.Atan2(rotation.y, -rotation.x) * Mathf.Rad2Deg; transform.rotation = Quaternion.Euler(0, 0, -rotZ); }

New to to game developement so sorry if this question is stupid: Why do we need a vector3 if we are in a 2d enviroment? Also what does the whole RotZ thing do in the script?

a Vector2 only have x and y but a vector 3 have x,y and z

Hi dude, nice video but I have a question, how can I make the shoot at mouse position with a rectangle? I noticed the incorrect face of the rectangle (side face) points the mouse

[@mrfhg9367]

is there any way to change the center of the rotating weapon? Mine is below the player

[@Autta_GUM]

Can anyone help? My character goes from left to right. When he turns left, the RotatePoint turns with him. Because of that, when he turns left, everything reverses; and the bullets just go into my character.

[@yf-maxi]

I added this code in the update function to flip the weapon when it goes above the player's head or below their feet so it's always facing the right direction. weaponRotation is just a sprite renderer I made the the top of the script. And the Weapon tag is on the game object with the weapon sprite. I hope this helps anyone trying to achieve the same thing. weaponRotation = GameObject.FindGameObjectWithTag("Weapon").GetComponent(); if (rotZ > 90 || rotZ < -90) { weaponRotation.flipY = true; } else { weaponRotation.flipY = false; }

[@SuperCosmicSpaceMagnet]

So invaluable for my coursework - thanks so much! Why are you using Vector3 here though? I thought trying to use Vector3 in Unity2D caused the universe to implode.

[@morebblakeyyy]

Vector2 would’ve been fine here! Wouldn’t affect this situation using vector3, but for clarity it probably would’ve been better for vector2. Luckily the universe was fine in this case though

[@SuperCosmicSpaceMagnet]

Ah okay. Thanks so much for the reply! Programming is an anathema to me, so having videos like this that clearly articulate everything step-by-step are immeasurably helpful. I was never taught C#, so I'm learning by doing. Without resources like yours I'd very literally be failing my degree right now because of this one module. @@morebblakeyyy

[@johnviti6245]

i have a propel the roation point isnt following my mouse instead its doing what ever my mouse does but on the other side if i am at the left of my player the rotation is on the right and if i move up my aim the rotation goes down any way to fix it?

The shooting works fine but I can't seem to figure out how to detect when the bullet hits an enemy, any help?

[@krinspah8399]

void OnTriggerEnter2D(Collider2D other) { if(other.CompareTag("Enemy")) { DestroyProjectile(); } } void DestroyProjectile() { Destroy(gameObject); } Add a trigger to your bullet on the inspector, and make sure your enemy matches the tag, in my case its enemy

[@foxxtronix6556]

praying you still respond, this is the exact type of shooting i wanted but couldn’t find and finally found it. but im at 4:51 in the video and my gun doesn’t move with the mouse like it should

[@gamesquad6743]

Can you do a boss fight tutorial?

[@PlagenShiki]

This doesn't seem to work for me. I did things step-by-step, and while the little black sprite moves a bit, it is only a bit up and down. It won't follow the mouse completely.

[@morebblakeyyy]

this does still work! :)

[@Gazntyno]

This is a great tutorial! The only issue I'm having is that since my game is set up like a 2D platformer like Mario whenever I change direction ( from right to left ) the bullet transform flips and I end up shooting inward instead of out outward. I was wondering if anyone has found a fix for this as I am a beginner game developer with minimal programming experience. Any help would be greatly appreciated :)

[@TheGamingRedCat]

I know this is late but maybe you could try running an if statement for this: if(playerFlipped == true) rotation *= -1; (basically just invert rotations to counteract player flip) probably inefficient but if you want to then you could do that (might not work actually im not sure lol)

[@Quarkes]

Brackeys have made a tuturial where he talks about enemy pathfinding, where he needs to flip the graphics of the enemy maybe that could work.

[@simonstechhacks]

Is the bullet supposed to make clones? I have no way to delete this so idk, I also made sure the bullet isnt in the Heirarchy and its in assets

[@airconditioningac]

I have a lot of bullets in my game so I had to make a new variable specifically for the clones and use the Delete function to prevent too much lag, so maybe this solution could work out for you // before the voids with your other variables private GameObject bulClone; public float bulletLife; // this is in seconds ... // under voidUpdate() if(Input.GetMouseButton(0) && canFire) { canFire = false; bulClone = Instantiate(bullet, bulletTransform.position, Quaternion.identity); Destroy(bulClone, bulletLife); // destroys the bullet clone after set number of seconds } I hope this helped with your problem :)

[@Great-Dao-of-Elegance]

I have an error which says that "object reference not set on an instance" the error is from the line "mainCam = GameObject.FindGameObjectWithTag " The bullet doesn’t move and stays from the position where I fire it from. Also I had to set the private Camera mainCam: to public in Shooting.cs for RotatePoint gameobject and drag the main camera towards the script. Because the gun won't move otherwise as it also shows the same error. I can’t do it with the Bullet script because when I drag the camera towards the bullet's script it says type mismatch.

[@unamusedrowlett6303]

Hey dunno if your still stuck but if I had to guess, its because the Tag on Camera is called something else. His code tracks the Tag of the camera rather than the actual game object.

really usefull but i cant see the bullet, can you help me please?. The Bullet exists and i can see it on the Scene window just not on the Game window

[@bblakeyyy]

What’s most likely happening is that it’s behind the camera on the Z axis. You need to add an offset in the script where you instantiate the bullet, so you combine a new vector 3 with where you currently spawn it So something like Vector 3 tempPos = new vector3(0,0,10) Instantiate(bullet, transform.position + temppos, quaternion.identity)

Ahh i fixed it. I took out the black box(gun) along the Y sxis from within the parent player object. After i reset the position of the gun (black box) i moved it along the y axis, it worked. Is it because Y axis is the default to follow along the rotation through Z axis?

I followed exactly the video, but after I turn it on and I want to shoot, the bullet doesn't appear. What should I do?

[@morebblakeyyy]

Check the hierarchy in game, it might be instantiating but it’s just behind the camera, or invisible, etc. If that’s not the case, there must be some code that’s not running correctly. Double check capital letters etc

I know this is a late response but if you want to make the bullet disappear you will need to do one of two things.
