[@GDTitans]

[@maxshinobi6092]

Hey, great tutorial! The only issue I had, were the curly-braces { } after foreach and if statements. Seems like your code editor allows for { } to be skipped, but in most people's cases, they are mandatory, so make sure to use them, as it is really confusing and game-breaking without them. Cheers

[@max.playsgames]

you can skip them if you only do 1 line of code below the if statement so the code is neater, if you do more than 1 line you need to add them in

[@maxshinobi6092]

My set up is a bit different from your, instead of pressing next to see the next car, I have manipulated the code so all the cars show at the same time on the screen, I'm just wondering if there is a way to have a separate buy button underneath each car separately, I have been at this certain problem now for over a week, and I am pulling my hair out, so please could you direct me in the right direction, I'm fairly new to c, so if you can help will you please explain in dummy terms, thank you again for all your efforts, they are much appreciated within the unity circle :):):)

[@Apricot0034]

If the object you selected does not come to the scene although you write the codes, the edited codes I have thrown can be useful for you, you can change the object names according to your own I made it for the car.

[@Apricot0034]

using UnityEngine; public class CarSelect : MonoBehaviour { public GameObject[] cars; public int currnetCarIndex; // Start is called before the first frame update void Start() { currnetCarIndex = PlayerPrefs.GetInt("SelectedCar"); foreach (GameObject car in cars) car.SetActive(false); cars[currnetCarIndex].SetActive(true); } }

[@Apricot0034]

using UnityEngine; public class ShopManager : MonoBehaviour { public GameObject[] CarModels; public int currnetCarIndex; // Start is called before the first frame update void Start() { currnetCarIndex = PlayerPrefs.GetInt("SelectedCar"); foreach (GameObject car in CarModels) car.SetActive(false); CarModels[currnetCarIndex].SetActive(true); } // Update is called once per frame void Update() { } public void ChangeNext() { CarModels[currnetCarIndex].SetActive(false); currnetCarIndex++; if (currnetCarIndex == CarModels.Length) currnetCarIndex = 0; CarModels[currnetCarIndex].SetActive(true); PlayerPrefs.SetInt("SelectedCar", currnetCarIndex); } public void ChangePre() { CarModels[currnetCarIndex].SetActive(false); currnetCarIndex--; if (currnetCarIndex == -1) currnetCarIndex = CarModels.Length -1; CarModels[currnetCarIndex].SetActive(true); PlayerPrefs.SetInt("SelectedCar", currnetCarIndex); } }

[@Apricot0034]

I made these edits and now the object I want comes to the scene (have a nice day)

[@ntb1132]

Will this still show the selected car in the level if I dont directly go to the level scene after choosing a car

Hi GDTitans, i have one problem. my game contains touch controls button. if i select a car out of other cars then i have to reassigne the functions to the event trigger buttons for that particular car. How to solve this ? Help

[@maxshinobi6092]

Hey, if you are using EventTrigger to trigger functions on buttons, then you might wanna do this: public void NextCar(bool next) { if (next) { //code } } public void PreviousCar(bool previous) { if (previous) { //code } } Then in the EventTrigger add PointerClick as an Event Type, hit +, drag the script to the specified box, assign the function and finally check the box (because our function is taking a parameter of bool). You should be good after this

[@gamedevelopment8556]

i just found your channel but i don't understand one thing here you showed different characters that we can select by purchasing but where is the full tutorial of this?

[@GDTitans]

I have used a standard asset from the unity asset store. So, you could add a shop system to any game but if you want to see how I've added a shop to my 2d platfomer from scratch watch this video kzbin.info/www/bejne/lanNpK2cjaeNm9E

[@dighidon7207]

Hi mate! Beautiful tutorial as usual, been following the Wheel Runner and I ended up here, so everything working fine but when I do select another player from the menu it will not assign automatically the 'Animator Controller' in the PlayerController script so it will not perform the animations.. I have been searching around forums and stuff to get it on my own but I don't understand how to do that. I would appreciate your help, thanks a lot for everything you do for the community!

[@GDTitans]

I created a prefab for each character (with its animator controller, 3d model, and scripts..) then added a script to instantiate the selected character(prefab).

[@dighidon7207]

@@GDTitans Thanks GD! So basically the script PlayerController now should go on the player itself then I make a prefab and how would look a script to instantiate the prefab? As I kinda tried make it work with changing the 'Animator animator;' to 'animator = GameObject.FindWithTag("Player")' into the 'start' function but it doesn't do any good :)) I thought that like that animator would be any object that has the tag player, same problem I have with the camera as in the script you made in the tutorial I have to select the player from the properties so once the player changes the camera would stay still.. I am really new to this so apologies if some things sound even stupid :)) I appreciate your time!

[@dighidon7207]

@@GDTitans Ok I think I sorted the character selection by creating the prefabs for each one and in the 'CarContainer' I've added directly those prefabs and it seems to be working, now I am trying to figure out how to make the camera understand that the player has been changed and to follow the new one.. :))

[@dighidon7207]

Ok another update ahaha I've sorted the cameras by creating a CameraHandler inside the player with a Camera attached and adding the CameraController to each CameraHandler so any player I am choosing from beginning it doesn't affect the cameras :)) Idk if it's the right way but it's working :)) Last problem I am going really crazy to solve is the TileManager that needs a PlayerTransform to know when to spawn new tiles :)) Maybe I'll figure it out until you see this message but I try anyway ahah sorry for to bother!

Hello, i faced the same problem, if you solved it can you please tell me how you did it, I'm a beginner too

Hey @GDTitans my camera wont follow my other player i tagged it with Player

[@cubertastic971]

I figured out a way however I'm not completely sure if it's optimal but it works. Ok so first thing I did was I declared another variable for the 2nd character as public Transform target2 in the camera controller script. then, in the start function, there's a line of code for the offset like this: offset = transform.position - target.position I then subtracted the target2.position so now it's: offset = transform.position - target.position - target2.position then, in the FixedUpdate method, the first line used to be: Vector3 newPosition = new Vector3(transform.position.x, transform.position.y, offset.z + target.position.z); but then I changed it to Vector3 newPosition = new Vector3(transform.position.x, transform.position.y, offset.z + target.position.z + target2.position.z); You can then add more to the mix if you want to. Hope this helps

my guess is that there is something wrong in the shopmanager because it switches cars in the buying scene but then whenever I switch back to my main screen its still the same car its always been.
