Does anyone else have the issue where the cross hair seems to move in the inverted direction? If I change the camera to be on the other side of the scene then it fixes the problem but now that means that I have to worry about flipping everything else(like player movement etc). How do I fix the cursor so that It aims correctly no matter where the camera is?

everything works except as I move the cursor more, the bullets shoot further away from the cursor. also for me, my player object starts the game with its rotation not facing the cursor. its rotated 90 degrees away from the cursor but still shoots in the relative direction of it. any help, please?

How could I do it if I want to make a bullet shoot from the player to the direction where I touch the screen (on mobile phones)

[@Alicia0Cramel]

thank you!!

[@Wolfzoon]

So you first have a vector3 target, pointing to the same z as transform position, of which you substract player.transform.position, so difference would have a z value of 0. Then you divide what is essentially a 2d vector by it's magnitude, aka normalizing it, and then you normalize it again? Why?

You are awesome!

My ball rotates around the centre of the screen once I move it, how do I set the position of bullet fire on a moving player?

[@jacksaunders8527]

valid

[@christopherdoiron4294]

I have a character who runs around, rather than stationary turret like you. When I shoot, it seems like the angle is off as I move around myself. On the right hand side, bullet hits target. on the top and bottom, the bullet is a few degrees off. Doesn't matter how I center/reset positions of the objects and parents. It seems like its the math behind finding the angle, and how it doesn't match exactly with the position because of the screen dimensions? Does this make sense?

[@UglyDouglyss]

Did you make the gun in the player spot

[@jakanater7763]

you might have to subract or add by 90 btw

[@unversedunavailable793]

Great tutorial! One question though. Is it possible to make it so when the player holds down the button it keeps firing until they let go?

[@sweetys321]

Yes it is! In the part where you do the input for when you shoot just change it to getmousebutton and your done you might want to add a cool down to it though.

[@fongaming101]

Check sprite render sorting layer or projectiles z to 0. Test by switching to 3d mode.. maybe hit apply overrides on prefab

[@ZakRahman]

Nice tutorial! I encountered the following issues: I couldn't drag a script onto the camera. "Can't add script behaviour AssemblyInfo". I had to add it as a component within the camera itself. Not a problem. Secondly, my mouse directions for the cross hair were inverted, and any fix I tried to make just made the entire thing disappear.

[@shivambawa]

you must have named your script different than the class name just make both the class name and the script name same

[@x-blocks8092]

just write -target

[@pressstart6864]

If the cross hairs are inverted it’s because you’re using a different camera than I presented in the script. Like said above just invert the target values like so: crosshairs.transform.position = new Vector2(-target.x, -target.y);

[@MickMackMikkel]

How do you deallocate the projectiles after they have been generated in the scene, they just keep clogging up the game?

[@pressstart6864]

Not sure what you mean? You mean like remove them from the scene or object pooling?

[@MickMackMikkel]

@@pressstart6864 Like around the 8:00 mark, when you're shooting the projectiles, you can see that they are "kept alive" in your game. Sure it's no problem for a small tutorial, but for a bigger game these would have to be deleted in order for the game to run smoothly. I digged around and found out that you can destroy the projectiles using Destroy(name, time), so for instance you could write destroy(projectile, 1) to have them destroyed after 1 second, or you can destroy them when they leave the view...

[@pressstart6864]

Yes, I usually write a script to detect when objects leave camera view. I cover it in this video: Spawning Objects in Unity [Using Instantiate] kzbin.info/www/bejne/e2jKnqyiebhkeZY

[@AnonymousKhaos]

I want this except i want the crosshair to kinda sway around the mouse any ideas?

[@christianstein9242]

create a random number generator, with the number created being a reference, and add it to the mouse position calculation

[@kooltyme]

how do i set the magnitude of my velocity, my code wasnt exactly the same as yours, and idrk how to set my magnitude

[@kooltyme]

i want to do this since the bullet goes at diff speeds depending on how far away the cursor is.

[@kooltyme]

nvm i didnt need one, i just did direction*(bulletSpeed/(Mathf.Abs(direction.x)+Mathf.Abs(direction.y))
