RobotDK jitter

Дмитрий Мурашов vor 5 Monaten in General Questions aktualisiert von Thomas vor 5 Monaten 2
Hello, i add RobotDK API to game4automation if check on video Comm cycle in very long, without moving in RobotDK it's 3-5ms, during movment is is 1500ms, is any possibility to make it smaller and more stable? or it is problem of RobotDK ?


Here is code od RobotDK script.

using System;
using UnityEngine;
using Sharp7;
using System.IO;
using System.Collections.Generic;
using System.Linq;
using System.Linq.Expressions;

namespace game4automation

if (RDK == null)
{
notifybar = "RoboDK has not been started";
return false;
}

// Check if the RDK API is connected
if (!RDK.Connected())
{
notifybar = "Connecting to RoboDK OK!";
// Attempt to connect to the RDK API

if (!RDK.Connect())
{

notifybar = "Problems using the RoboDK API. The RoboDK API is not available...";
return false;
}

return true;

Hi, I checked your example on my computer. It moves smoothly on my side´(RoboDK and G4A),

I think your started to implement your own RoboDK Interface because you did not purchased professional version - right?

It could save you some time to use G4A Professional. Please get in contact with me if you need an offer.

Normally it should be faster. Looks like your computer resources are limited but I am not sure if there is another problem.

To be able to check you would need to provide your project (RoboDK including G4A) to us.

Please send us your project by using https://game4automation.com/send
