spent a while using other screen to world point methods, this cleaned up so many of the issues I was having! Thanks a ton!

[@GamingAlgen]

This is so clear and perfect! Thanks!

[@noworldorder]

This was incredibly helpful! Thank you so much for sharing friend.

[@clockknight13]

Thanks so much! This is a very simple and elegant solution, helped me a lot in learning how to program :)

[@barthaszabolcs-gamedevjour1098]

Thank you, always glad to hear it helped. :d Best of luck with programming, it can be hard and there is a lot to learn, but it's worthwhile. :)

[@Lazzarus7]

Very inspiring, thank you for sharing and explaining

Thanks, i was stacked in a step!

Wow, thanks! This worked for me very well

You are welcome. Happy new year. :)

[@dmitriybelousov7246]

My best regards ! That is great and useful work !

[@TheKr0ckeR]

Great guide. Thank you. How would we solve the problem of not having any collider? It just stucks there. I have some enviroments which is not a ground, and even an empty area, rotation is just stuck. Isnt there any way to look it with MouseWorldPos?

[@GabiMartin97]

Works like a charm

[@hawkgamedev]

You are a genius thanks!

[@PedroGuijarro_]

Insane, works great!

[@barthaszabolcs-gamedevjour1098]

Thanks! :)

[@rijkmulder276]

how do you fix the problem of when aiming at the ground that the bullets arent going straight though the mouse but at a slight offset because youre shooting at a constant height?

I love you man, you are my superman, thank you so much!

[@IndieScapeGames]

Nice tutorial!

[@barthaszabolcs-gamedevjour1098]

Thank you! :d

helped a lot, thanks bro :)

You are welcome, bro. :p

[@reap8624]

it doesnt work whenever i try to use it it gives me an NullReferenceException error for the Getmouseposition() method

[@Usual_User]

Thank you, this help me alot!

[@barthaszabolcs-gamedevjour1098]

Glad to hear that! :)

[@criptas1985]

TNX SO MUCH!!! U r my hero dude :D

[@brehiner25]

I love this video but I wonder if you have this script for the unity touch system?

[@BlueAndy_]

Thanks a lot, very kind of you

[@hidden2world894]

where did u get the turret? or did u make it?

[@piruzRo]

it works great but the moving controls are inverted do you knowk how to fix that ?

[@darthvaderisawesome2573]

THANK YOU VERY MUCH SIR !

[@8BitTie]

Thank you so much I am new to coding and I hate copying scripts because I don't know what dose what. But in this case I actually don't feel bad about copying because now I know what each part of the script dose thank you I will subscribe can't wait to learn more about coding

[@barthaszabolcs-gamedevjour1098]

Am glad you could follow. :D I would say you should always try to understand the script that you copy, but don't feel bad just because you don't know exactly what is what. Also try experimenting with scripts that you copy, changing it a bit then testing out what did it changed. I found this to be a good way to test my understanding. Thanks for the sub. :)

[@64mxg]

GRACIAS!!! justo lo que quiera comprender, como ahcerlo de una mejor manera :D

[@halivudestevez2]

for newbies: the return type is a "Tuple". Easy to use, but can be unusual to see it.

[@halivudestevez2]

Tuple: you can return multiple items at once without defining a new structure for it.

[@yeahzerek]

I might be slow but, how do you add that laser and circle thing on the ground? Also how to you make the shooting?

[@barthaszabolcs-gamedevjour1098]

You are not being slow, I did not explained that part in the tutorial. :D I only meant to use it for the looks, but you can use it of course. If you want to copy the laser, download the project (github.com/BarthaSzabolcs/Tutorial-IsometricAiming), then check out the scene Example_Turret, in the hierarchy look for the GameObject; Turret > Head > Laser. The Laser object has a LineRenderer script, this is what draws the line. This is the first part. You also have to update the line every frame, so it won't go through the obstacles. You can find the logic in the script: Assets\Scripts\WithGizmos\IsometricAimingWithGizmos.cs, look for the function RefreshLaser() at line 162. The "circle thing" is a Gizmo, and can only be seen in the editor and if it is enabled, so this might not be what you want. You find it in the same script in the function OnDrawGizmos() at line 68. For the Shooting, same script, look for function Shoot() at line 153. This will spawn a projectile at the end of the barrel, and set it to face where you are aiming. The rest of the logic is in the Assets\Scripts\ExtraStuff\Projectile.cs In the Start() function it will set its velocity to go forward with speed. This works because Start() will be called after the projectile is set to face where you aim. Also you can find the logic to destroy the projectile on collision. Of course you will have to create a Projectile prefab that can be spawned. You can find the prefabs at Assets/Prefabs. If you get lost with the setup, check the Turret GameObject in the Example_Turret scene. I think that's all. Good luck! :D

[@2800Print]

Someway of doing this with bp ?

[@allanramos6855]

Nice code and tutorial

[@barthaszabolcs-gamedevjour1098]

Thank you! :)

[@tylerguitar75]

What if your player is standing on sloped terrain? Would you make him shoot at a slope equal to the terrain?

[@maximeumbra7235]

You've got two easy options on how to handle that, you first find that target position using this method then Raycast from world up down to it and set it to your desired height. If you want to get really fancy you then Raycast from a character source (say from a gun or the eyes) towards that new point and if you hit something before you reach that distance you could take that point and add some height to it or do raymarching to find the closest edge to aim as close as you can towards that desired target.

[@Xeratas]

wouldn't you have to considder the camera angle? otherwise depending on the camera angle you will not always aim exact - please correct me if iam wrong here

[@fercon9892]

you are correct, this only works if the camera literally never moves, which is frustrating.

[@EvertuGameTools]

friend, could you tell me the name of this kind of method "GetMousePosition"😮

[@barthaszabolcs-gamedevjour1098]

Sorry, I don't understand the question. What do you mean?

[@lazyonii-chan3885]

Is this possible on mobile? I want to make a top view game on mobile.

[@barthaszabolcs-gamedevjour1098]

You probably want twin-stick controls instead, where you move with the left stick amd control the direction of your player by the right analog stick. The method in the video would only work if the player continuously touches the screen, which would be distracting for a fast paced shooter.

[@lazyonii-chan3885]

@@barthaszabolcs-gamedevjour1098 already did this one, i did it using movement joystick on the left and attack button on right. Thank you!

Thanks. :)

[@vaepuer2290]

Doesnt work for me, but i'm slowly understanding this more

[@barthaszabolcs-gamedevjour1098]

Sad to hear it did work. Try to watch the tutorial again and spot any difference in your project and mine. You can also download the project, may be you can adapt the working code from there easier.

[@vaepuer2290]

@@barthaszabolcs-gamedevjour1098 yea i tried adapting the full project to understand more, changed the camera to a dkfferent angle and yours worked flawlessly, however mine witht the exact same didnt. Probably just something i gotta put up on the forums

[@barthaszabolcs-gamedevjour1098]

It's hard to guess, but I would start with the raycasting, may be your ground has no collider or the layermask is not set correctly.

this is not 2.5D, 2.5D was a term used for 2D graphics that mimic 3D. All I see here is 3D in a 3D world!

[@barthaszabolcs-gamedevjour1098]

I got your point, but 2.5D often refers to a 3D game, with 2D gameplay. I did not want to call it top down aiming, cause you can achieve this easier in a traditional 2D top down game and there are a bunch of videos about it already. I think it's clear from the thumbnail what I mean by 2.5D. It's not necessarily correct, but I don't think it's misleading. What would you title it? :d

[@71Arlekino]

Instead of transform.forward = direction * Time.deltaTime; it is better to write like this, for smooth rotation: Quaternion direction = Quaternion.LookRotation(movement); transform.rotation = Quaternion.Lerp(transform.rotation, direction, rotSpeed * Time.deltaTime); Also sorry, but the accent is making my ears droop.
