Unity learning notes (realize the conveyor belt)

---

Unity Analog conveyor belt

1. Model structures,

2. Add part

2.1 Add trigger

Add a trigger to the conveyor , So that when the object stays on the conveyor belt, it can move forward .

2.2 Set the empty object as the end position of the conveyor belt

2.3 Set the switch and speed acceleration device for the conveyor belt

The conveyor belt switching device shown in this display is controlled by the space bar , The acceleration device passes through the digital 1 control

3. Source code

public GameObject belt;
    public Transform endpoint;// Get the end position 
    public int currentSpeed;// Current speed 
    public int maxSpeed;// Maximum belt speed 
    public bool belton=false;// Determine whether the conveyor belt is open 

    private void Update()
    {
        if (Input.GetKeyDown(KeyCode.Space))
        {
            PowerSwitch(); 
        }

        else if (Input.GetKeyDown(KeyCode.Alpha1))
        {
            ChangeSpeed();
        }                 
    }
    void ChangeSpeed()
    {
        if(currentSpeed>=maxSpeed)
        {
            currentSpeed = 0;
        }
        else
        {
            currentSpeed++;
        }
    }
    void PowerSwitch()
    {
        if(belton)
        {
            belton = false;
        }
        else
        {
            belton = true;
        }
    }
 
    private void OnTriggerStay(Collider collider)
    {
        if(belton)
        { 
            collider.transform.position = Vector3.MoveTowards(collider.transform.position, endpoint.position, currentSpeed * Time.deltaTime); 
        }
    }
