使用

节点端口值的获取与操作

正常的出端口和入端口值获取

[System.Serializable, NodeMenuItem("Conditional/Switch")]
public class SwitchNode : BaseNode
{
	[Input(name = "In")]
 	public float input;
	[Output(name = "Out")]
	public float				output;
	public override string		name => "Switch";
	
	protected override void Process()
	{
 	//获取入端口的值,第一个参数为要获取值的字段名称,推荐使用nameof
 	//第二个参数是要获取值的字段,使用ref传递方便进行修改
		TryGetInputValue(nameof(input), ref input);
		output = output = input * 42;
	}
	
 	/// <summary>
	/// 获取出端口的值
	/// </summary>
	/// <param name="outputPort">output端口</param>
	/// <param name="inputPort">与上面的output端口相连的input端口</param>
	/// <param name="value">要返回的值</param>
	/// <typeparam name="T"></typeparam>
	public override void TryGetOutputValue<T>(NodePort outputPort, NodePort inputPort, ref T value)
	{
		if (output is T finalValue)
		{
			value = finalValue;
		}
	}
}

单个入端口连接了多个出端口

[System.Serializable, NodeMenuItem("Custom/MultiAdd")]
public class MultiAddNode : BaseNode
{
	[Input]
	public IEnumerable< float >	inputs = null;
	[Output]
	public float				output;
	public override string		name => "Add";
	protected override void Process()
	{
		output = 0;
		inputs = TryGetAllInputValues<float>(nameof(inputs));
		if (inputs == null)
			return ;
		foreach (float input in inputs)
			output += input;
	}
	public override void TryGetOutputValue<T>(NodePort outputPort, NodePort inputPort, ref T value)
	{
		if (output is T finalValue)
		{
			value = finalValue;
		}
	}
	[CustomPortBehavior(nameof(inputs))]
	IEnumerable< PortData > GetPortsForInputs(List< SerializableEdge > edges)
	{
		yield return new PortData{ displayName = "In ", displayType = typeof(float), acceptMultipleEdges = true};
	}
}

出端口的自定义处理

[System.Serializable, NodeMenuItem("Custom/CircleRadians")]
public class CircleRadians : BaseNode
{
	[Output(name = "In")]
	public List< float >		outputRadians;
	public override string		name => "CircleRadians";
	public override void TryGetOutputValue<T>(NodePort outputPort, NodePort inputPort, ref T value)
	{
 	//因为此节点会根据出端口所连接的多个入端口顺序为入端口分配值,所以需要判断传进来的inputPort的Index
		int inputPortIndexInOutputPortEdge = outputPort.GetEdges().FindIndex(edge => edge.inputPort == inputPort);
		if (outputRadians[inputPortIndexInOutputPortEdge] is T finalValue)
		{
			value = finalValue;
		}
	}
}

[System.Serializable, NodeMenuItem("Custom/Inheritance2")]
public class Inheritance2 : Inheritance1
{
 [Input(name = "In 2")] public float input2;

 public float field2;
 public override string name => "Inheritance2";
 protected override void Process()
 {
 base.Process();
 TryGetInputValue(nameof(input2), ref input2);
 output2 = input2 * 44;
 }
	
 public override void TryGetOutputValue<T>(NodePort outputPort, NodePort inputPort, ref T value)
 {
 //因为此节点有多个输出端口,所以需要判断所需要的数据是哪个端口
 switch (outputPort.fieldName)
 {
 case nameof(output1):
 if (output1 is T finalValue1)
 {
 value = finalValue1;
 }
 break;
 case nameof(output2):
 if (output2 is T finalValue2)
 {
 value = finalValue2;
 }
 break;
 }
 }
