Inputs are not updated before actions

The input data of connected nodes are not updated until after the onAction event. I have even tried moving the trigger to after I set the output data of the node.

Lachee Console Node

//Show value inside the debug console
function LConsole()
{
	//this.mode = LiteGraph.ON_EVENT;
	this.size = [80,30];
	this.addInput("log", LiteGraph.EVENT);
    this.addInput("cnt", 0, { label: "Message"});
    this.cnt = "";
}

LConsole.title = "Lachee Console";
LConsole.desc = "Show value inside the console";

LConsole.prototype.onAction = function(action, param)
{
    console.log("Action:", action );
    console.log("Params:", param );
    console.log("Self:", this );
    console.log("CNT: " + this.cnt );
    console.log("A: ", this.getInputData(0));
    console.log("B: ", this.getInputData(1));	
    
	this.inputs[1].label = this.cnt;
}

LConsole.prototype.onExecute = function()
{
    if (this.inputs[1])
        this.cnt = this.getInputData(1);
}

LConsole.prototype.onDrawBackground = function(ctx)
{
	//show the current value
	this.inputs[1].label = this.cnt;
}

LiteGraph.registerNodeType("basic/lconsole", LConsole );

On Message Node

function OnMessageEvent()
{
	this.addOutput("on_message", LiteGraph.EVENT);
	this.addOutput("author", 0);
    this.addOutput("content", 0);
    this.author = "Lachee";
    this.content = ".ping";
    this.triggered = false;
    this.clonable = false;
    this.resizable = false;
    this.color = LGraphCanvas.node_colors.purple.color;
    this.bgcolor = LGraphCanvas.node_colors.purple.bgcolor;
}

OnMessageEvent.title = "On Message";
OnMessageEvent.desc = "Occurs when a message is sent";

OnMessageEvent.on_color = "#AAA";
OnMessageEvent.off_color = "#222";


OnMessageEvent.prototype.onStart = function() {}

OnMessageEvent.prototype.onDrawBackground = function()
{
	this.boxcolor = this.triggered ? OnMessageEvent.on_color : OnMessageEvent.off_color;
	this.triggered = false;
}

OnMessageEvent.prototype.onExecute = function()
{
	var dt = this.graph.elapsed_time * 1000; //in ms
	var trigger = message_queue.length != 0;

    if (trigger)
    {
        console.log("TRIGGER");
        this.setOutputData(1, "Lachee");
        this.setOutputData(2, message_queue[0]);
        this.trigger("on_message", message_queue[0]);
        message_queue = [];
        this.triggered = true;
    }
}

Was this ever implemented? It would be interesting to be able to execute backwards the inputs of the event nodes, so that they can get fresh values without needing to run the entire tree. From what I understand, that’s what Blueprints does. In the end most javascript applications will be more event-based than frame-based

I will research on the topic this week, I could create a function that executes from Node triggering the event to the node receiving the event.

Ask me about it in one week
