How to read Keyboard input from C# script using nodes

[FlorianLance]

Thank you for the amazing support.
Below is my attempt to read the keyboard input from slot 5:

####################
// system
using System;
using System.Reflection;
using System.Collections.Generic;

// unity
using UnityEngine;

namespace Ex{


public class CS_move_cube : BaseCompiledCSharpComponent{

    CubeComponent Cube = null;
    // Ex component flow functions, uncomment to use
    // # once per loading
    public override bool initialize() {
        Cube = (CubeComponent)get("Cube");
        return true;
    }
 
    public override void update() {
        
        var CubeConfig = Cube.current_config();
        Vector3 CubePos = CubeConfig.get<Vector3>("position");
        float CubeHeight = CubePos.y;
        
        var idV = (IdAny)slot5;

        if(idV.id == 0){
            CubeHeight += 0.1f;
        }else if(idV.id == 1){
            CubeHeight -= 0.1f; 
        }
                   
        // # a TransformValue
        TransformValue trV = new TransformValue();
        trV.position = new Vector3(CubePos.x, CubeHeight, CubePos.z);
        trV.rotation = Quaternion.Euler(new Vector3(0, 0, 0));
        trV.scale = Vector3.one;

        Cube.current_config().set_transform("transform", trV);

    }       
}

}

I get the following error:

[COMPILER] Compilation error CS0428 : "Cannot convert method group slot5' to non-delegate type Ex.IdAny'. Consider using parentheses to invoke the method" from file D:/Michel/ExVR/PPS_reaching/assets/CS_move_cube.cs at line 27 and column 25

An alternative would be the read directly the keyboard within the script. If this would be the preferred way, what is the correct way to "catch" the latest pressed key ? last_event() or send_infos_and_signals()

If you want to retrieve data from a script using nodes, you have to uncomment the corresponding slots functions from the code,
in your case you are using the slot n°5, (you could have used even the others with an IdAny, by using the slot 5 it is already converted, it's a small convenience)

    // # slots
    public override void slot1(object value) { 
    
    }
    //public override void slot2(object value) { }
    //public override void slot3(object value) { }
    //public override void slot4(object value) { }
    public override void slot5(IdAny idValue) {
        int id = idValue.id;
        object value = idValue.value;
    }

So your class will look like this:

// system
using System;
using System.Reflection;
using System.Collections.Generic;

// unity
using UnityEngine;

namespace Ex {

    public class CS_move_cube : BaseCompiledCSharpComponent {

        CubeComponent Cube = null;
        Vector3 currentCubePosition = new Vector3();
        // Ex component flow functions, uncomment to use
        // # once per loading
        public override bool initialize() {
            Cube = (CubeComponent)get("Cube");
            return true;
        }

        public override void start_routine() {

            // we retrieve the position of the cube at the beginning of the routine
            var currentC = Cube.current_config();
            // there was a typo in the doc, if we want a TransformValue we need to call "get_transform_value" and not "get_transform"
            TransformValue trV = currentC.get_transform_value("transform");
            currentCubePosition = trV.position;
        }

        public override void slot5(IdAny idValue) {

            // this function is called everytime a value is passed throught the slot n°5 of the script node

            int id = idValue.id;
            //object value = idValue.value; // we don't use the value part of IdAny
            if (id == 0) { // we increment or decrement the height according to the input id                
                currentCubePosition.y = currentCubePosition.y + 0.1f;
                log_message("Move cube UP! " + Converter.to_string(currentCubePosition));
            } else if (id == 1) {
                currentCubePosition.y = currentCubePosition.y - 0.1f;
                log_message("Move cube DOWN! " + Converter.to_string(currentCubePosition));
            }

            // we update the cube current config transform
            TransformValue trV = new TransformValue();
            trV.position = currentCubePosition;
            trV.rotation = Quaternion.Euler(new Vector3(0, 0, 0));
            trV.scale    = Vector3.one;
            Cube.current_config().set_transform("transform", trV);
            Cube.update_from_current_config(); // important, we need to call this in order to the changed to be taken into account
        }
    }
}

Thank you! This issue can be closed on my side.
