# Invoke(string, float)

> Invokes the method methodName in time seconds.

## Definition

* **Type:** Method
* **Namespace:** [UnityEngine](/engine/6000.0/script-reference/unityengine.md)
* **Assembly:** UnityEngine.CoreModule

```csharp
public void Invoke(string methodName, float time)
```

### Parameters

**** (\[string]\(https\://learn.microsoft.com/dotnet/api/system.string)): **** (\[float]\(https\://learn.microsoft.com/dotnet/api/system.single)): 

### Remarks

If time is set to 0 and Invoke is called before the first frame update, the method is invoked at the next Update cycle before [MonoBehaviour.Update()](/engine/6000.0/script-reference/unityengine/monobehaviour/update.md). In this case, it's better to call the function directly.

Note: Setting time to negative values is identical to setting it to 0.

In other cases, the order of execution of the method depends on the timing of the invocation.

If you need to pass parameters to your method, consider using [Coroutine](/engine/6000.0/script-reference/unityengine/coroutine.md) instead. Coroutines also provide better performance.

### Examples

```csharp
using UnityEngine;
using System.Collections.Generic;

public class ExampleScript : MonoBehaviour
{
    // Launches a projectile in 2 seconds

    Rigidbody projectile;

    void Start()
    {
        Invoke(nameof(LaunchProjectile), 2.0f);
    }

    void LaunchProjectile()
    {
        Rigidbody instance = Instantiate(projectile);
        instance.velocity = Random.insideUnitSphere * 5.0f;
    }
}
```
