Programming_Tutorial

This Unity project is meant to serve as an introduction to programming concept by provided learners with a simple block of code, and an interactive view that they can easily associate with said code.

By looking at the contents of the main class (IntroToProgramming), learners can associate concepts like int and float with visible representations, as well as function calls and variables.

While interacting with the game, the learner can follow along with the code:

public class IntroToProgramming : MonoBehaviour
{
        //These are the variables you see on screen.
        //They are "declared" in this section - that means we are announcing to the computer that it must allocate memory to store these values, and that they will be accessible by name.
        [SerializeField] 
        private int numberOfObjectsToCreate = 1;
        
        [SerializeField] 
        private float objectScale = 1;
        
        [SerializeField] 
        private Color modelColor = Color.white;

        [SerializeField] 
        private GameObject model;

        [SerializeField] 
        private int numberOfObjectsInScene = 0;

        [SerializeField] private Transform spawnPoint;

        //This is a method! It makes our class do something.
        //Can you tell what this method does?
        public void CreateButtonAction()
        {
                numberOfObjectsInScene = numberOfObjectsInScene + CreateObjects(numberOfObjectsToCreate, model, modelColor, objectScale);
        }


        //This is another method. It has a return type (int), meaning that after it runs, it will return a value to you. You'll need to decide if you want to do something with it.
        //This method also accepts parameters: can you tell what they're for?
        private int CreateObjects(int num, GameObject model, Color color, float scale)
        {
            for (int i = 0; i < num; i++)
            {
                GameObject item = Instantiate(model, spawnPoint.transform.position+Vector3.up*i, RandomQuaternion());
                SetColorAndScale(item, color, scale);
            }

            return num;
        }

        //Here's another method. It doesn't return a value. What does it do?
        private void SetColorAndScale(GameObject item, Color color, float scale)
        {
            ApplyColor(item, color);
            item.AddComponent<Rigidbody>();
            item.transform.localScale = Vector3.one * scale;
            ApplyLayer(item, "Default");
        }

        void ApplyColor(GameObject obj, Color col)
        {
            MeshRenderer[] renderers = obj.GetComponentsInChildren<MeshRenderer>();
            foreach (MeshRenderer mr in renderers)
            {
                foreach (Material mat in mr.materials)
                {
                    mat.color = col;
                }
            }
        }
