hi, i need my code to execute a function every 1 second, i have them placed in the update() function, however it is being called too frequently. What is a solution?

Game coding 101 - Update() runs every frame regardless :wink:

From the Start() function instead call

InvokeRepeating("YOUR FUNCTION NAME", 0, 1.0);

"Your function name " should be the function which has the code you want execution every 1sec see http://unity3d.com/support/documentation/ScriptReference/MonoBehaviour.InvokeRepeating.html

You can try this simple way fo more precision than InvokeRepeating :

    // Next update in second
    private int nextUpdate=1;
    
    // Update is called once per frame
    void Update(){
    
    	// If the next update is reached
    	if(Time.time>=nextUpdate){
    		Debug.Log(Time.time+">="+nextUpdate);
    		// Change the next update (current second+1)
    		nextUpdate=Mathf.FloorToInt(Time.time)+1;
    		// Call your fonction
    		UpdateEverySecond();
    	}
    
    }
    
    // Update is called once per second
    void UpdateEverySecond(){
    
    // ...
    
    }

You can also try this:

    int interval = 1; 
    float nextTime = 0;
	
    // Update is called once per frame
    void Update () {

        if (Time.time >= nextTime) {

             //do something here every interval seconds

             nextTime += interval; 

        }
	
    }

int interval = 1;

    void Update()
    {
        if (Time.time % interval == 0)
        {
            // Your call
        }
    }
