Godot-UniCoroutine

A coroutine system similar to Unity engine for Godot C# version.

Setup

Copy the code to your Godot C# project.

Usage

1. Define your coroutine tasks.

   • Waiting Task (Waiting for Time/Input)

      IEnumerator TestTask(){
      	GD.Print("Start TestTask...");
      	GD.Print("Wait 3 Sec");
      	yield return new WaitTime(3);
      	GD.Print("Wait Until Space Pressed.");
      	isSapcePressed = false;
      	yield return new WaitUntil(()=>{return isSapcePressed;});
      	GD.Print("Wait 3 Sec");
      	yield return new WaitTime(3);
      	GD.Print("TestTask Done!");
      }

   • Animation Task (Movement/Rotation)

      IEnumerator ImageTask(){
      	Sprite2D sp = this.FindChild("Sprite2D") as Sprite2D;
      	if(sp != null){
      		GD.Print("Start ImageTask...");
      		float endPosX = sp.Position.X+300;
      		while(true){
      			float deltaTime = CoroutineSystem.instance.deltaTime;
      			sp.Position += new Vector2(100 * deltaTime,0);
      			sp.Rotation += 90*deltaTime*(float)Math.PI/180;
      			if(sp.Position.X > endPosX){
      				break;
      			}
      			yield return null;
      		}
      		GD.Print("ImageTask Done!");
      	}
      }

2. Start Coroutine

   Using the StartCoroutine method to start your tasks, it will auto create the CoroutineSystem node and add to your scene tree as "CoroutineSystem".

   var cs = CoroutineSystem.instance;
   cs.StartCoroutine(ImageTask());
   cs.StartCoroutine(TestTask());

3. Stop Coroutine

   Using StopCoroutine to stop your couroutine tasks.

   var cs = CoroutineSystem.instance;
   cs.StopCoroutine("ImageTask");

Get the delta time

• All the tasks are processed by the CoroutineSystem node.
  You can get the delta time from the CoroutineSystem instance.

   IEnumerator GetDeltaTimeTask(){
   	while(true){
   		float deltaTime = CoroutineSystem.instance.deltaTime;
   		GD.Print($"DeltaTime:{deltaTime}");
   		yield return null;
   	}
   }
