Vehicle selection screen

Hi, here's how I'd do it:

In any game I make which uses levels, I tend to make an empty GameObject called "theBrain" which sits on Level0 and has the following script attached so it will persist across all the subsequent levels:

Code (csharp):

1. function Awake () {
2.     DontDestroyOnLoad (this);
3. }

I use "theBrain" script to also hold any recalled data from memory, high scores, playerNames, etc.

Then, once you have loaded any memory data etc. - just advance to Level1 (Main Menu), here you can choose to go to your car selection screen, etc.

In your selection screen, when the user clicks on a car they want to pick, they could actually just be clicking an invisible GUI button, and when they do so, the button they clicked tells a variable in theBrain's script which car was selected (1,2,3 or 4).

Now, whenever you move to any track levels, you can easily just ask theBrain which car prefab to instantiate.

Hope that makes sense?

Here's a few code snippets which might help (untested, simplified for illustration):

(Sure you can use an Array to hold the prefabs, but the below code does not go into that)....

LEVEL 0

Code (csharp):

1.  
2. // Brain Script (must be called BrainScript)
3.  
4. // A variable to remember which car the player chose:
5. var selectedPlayerCar : int;
6.  
7. function Awake () {
8.     DontDestroyOnLoad (this);
9. }
10.  

Level 1

Code (csharp):

1.  
2. // Car Selection Script
3.  
4. // Link to the Brain Script:
5. private var theBrain : BrainScript;
6.  
7. function Awake(){
8.     // Complete the reference to the Brain Script:
9.     theBrain = FindObjectOfType(BrainScript);
10. }
11.  
12. function OnGUI () {
13.     // Button 1 to choose Car 1
14.     if (GUI.Button (Rect (0, 0, 100, 20), "CAR1")){
15.         // Spin Car 1
16.        
17.         // Tell the Brain which car was chosen
18.         theBrain.selectedPlayerCar = 1;
19.  
20.         // Go back to Main Menu
21.     }
22.  
23.     // Button 2 to choose Car 1
24.     if (GUI.Button (Rect (0, 100, 100, 20), "CAR2")){
25.         // Spin Car 2
26.        
27.         // Tell the Brain which car was chosen
28.         theBrain.selectedPlayerCar = 2;
29.  
30.         // Go back to Main Menu
31.     }
32.  
33.     // etc.
34.  
35. }
36.  

Level 2

Code (csharp):

1.  
2. // Racing Track Script
3.  
4. // Link to the Brain Script:
5. private var theBrain : BrainScript;
6.  
7. function Awake(){
8.     // Complete the reference to the Brain Script:
9.     theBrain = FindObjectOfType(BrainScript);
10. }
11.  
12. function Start(){
13.    
14.      if (theBrain.selectedPlayerCar == 1 ){
15.        
16.         // Instantiate Car 1
17.  
18.     }
19.  
20.      if (theBrain.selectedPlayerCar == 2 ){
21.        
22.         // Instantiate Car 2
23.  
24.     }
25.  
26. }
27.  

Hey, I'm not saying this is the only way to do this, but it's the easiest to explain! :razz:

 

I can help. Ill send an example project of what I use when I finish my homework...
I dont really use and array to select them. It takes a little longer to set up but it works.

Edit: oh we posted at the same time. Hey James if you still want it tell me, but RobbieDingo's is pretty similar

 

James,

You'll need some good-looking UI to present the cars, probably in a spinner or line-up of cars where the "active" car is scaled up a little more than the others, a la Crusin USA or some other coin-op racing game. You'll need to track what is the active car and store is once the user has made a selection... Then, you'll need to be able to access that car throughout the game, within other levels, etc. So the selected car needs to be stored rather permanently.

I would use static variables in my "CarSelection" scripts so that the selected car can be accessed by (and potentially changed by) any other script. So, after the car is selected, you could write (and yeah, this is pseudocode...):

Code (csharp):

1. CarSelection.selectedCar = <the car the user selected. selectedCar is a GameObject>;

later, when you want to Instantiate said car in some other script - say, level 1, you would call that car like this:

Code (csharp):

1. Instantiate (CarSelection.selectedCar, Vector3.zero, Quaternion.identity);

Hope this helps.

 

Cheers James.

To do a texture swap, just have an array of the materials (assigned in the inspector) and do the same thing as I suggested above - ie. use the brain to remember the integer which will point to the position in the array.

Good luck!

I learned to do character selection from the Unity Tutorial by the same title. Techniques ought to be similar to vehicle selection with texture swaps.

Please share that tutorial because i am also stuck at the same problems from selecting the vehicle ...

 

How can I do it to Prefabs(Cars)?
