@benogden1409 2 года назад

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?

@sadiulakhanji6271 4 года назад

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?

hello, in the world of submarines game, how to do the movement mechanics? with constant speeds, and the system that marks the ship to fire the torpedo?

@Wolfzoon 3 года назад

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?

Can someone help me my player isn’t pointing exactly towards my mouse but my bullets are

@christopherdoiron4294 2 года назад

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?

@ZakRahman 5 лет назад

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 5 лет назад

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

@x-blocks8092 4 года назад

just write -target

@pressstart6864 4 года назад

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 4 года назад

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

@pressstart6864 4 года назад

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

@MickMackMikkel 4 года назад

@@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 4 года назад

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] ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-E7gmylDS1C4.html

@wonsiastywons3436 3 года назад

If anyone (like me) had a problem to get rotation of a player working, I found other solution (for rotation): Vector2 positionOnScreen = transform.position; //Get the Screen position of the mouse Vector2 mouseOnScreen = (Vector2)Camera.main.ScreenToWorldPoint(Input.mousePosition); crosshair.transform.position = new Vector2(mouseOnScreen.x, mouseOnScreen.y); //Get the angle between the points float angle = AngleBetweenTwoPoints(positionOnScreen, mouseOnScreen); //Ta Daaa transform.parent.gameObject.transform.rotation = Quaternion.Euler(new Vector3(0f, 0f, angle));
