Egret.setInterval is a method in the Egret framework that allows you to execute a function repeatedly with a specified time interval. It is commonly used for creating animations or running tasks at regular intervals. The basic syntax for using Egret.setInterval is as follows:
```
egret.setInterval(callback: Function, thisObject: any, delay: number): number
```
- `callback`: The function to be executed at each interval.
- `thisObject`: The object to which the "this" keyword refers to inside the callback function (optional).
- `delay`: The time interval (in milliseconds) between each execution of the callback function.
The method returns a unique identifier (number) that can be used to clear the interval later using the `egret.clearInterval` method.
Here's an example usage of Egret.setInterval:
```typescript
let intervalId = egret.setInterval(() => {
console.log("Executing callback function");
}, this, 1000);
```
In this example, the callback function will be executed every 1000 milliseconds (1 second). The `this` keyword refers to the current object. The `intervalId` can be later used to clear the interval if needed using `egret.clearInterval(intervalId)`.
