      Hello guys, 
       
      Please tell me! 
      How do I know? Why does wavefront not show for me?
      I already checked I have non errors yet.
      using OpenTK; using System.Collections.Generic; using System.IO; using System.Text; namespace Tutorial_08.net.sourceskyboxer { public class WaveFrontLoader { private static List<Vector3> inPositions; private static List<Vector2> inTexcoords; private static List<Vector3> inNormals; private static List<float> positions; private static List<float> texcoords; private static List<int> indices; public static RawModel LoadObjModel(string filename, Loader loader) { inPositions = new List<Vector3>(); inTexcoords = new List<Vector2>(); inNormals = new List<Vector3>(); positions = new List<float>(); texcoords = new List<float>(); indices = new List<int>(); int nextIdx = 0; using (var reader = new StreamReader(File.Open("Contents/" + filename + ".obj", FileMode.Open), Encoding.UTF8)) { string line = reader.ReadLine(); int i = reader.Read(); while (true) { string[] currentLine = line.Split(); if (currentLine[0] == "v") { Vector3 pos = new Vector3(float.Parse(currentLine[1]), float.Parse(currentLine[2]), float.Parse(currentLine[3])); inPositions.Add(pos); if (currentLine[1] == "t") { Vector2 tex = new Vector2(float.Parse(currentLine[1]), float.Parse(currentLine[2])); inTexcoords.Add(tex); } if (currentLine[1] == "n") { Vector3 nom = new Vector3(float.Parse(currentLine[1]), float.Parse(currentLine[2]), float.Parse(currentLine[3])); inNormals.Add(nom); } } if (currentLine[0] == "f") { Vector3 pos = inPositions[0]; positions.Add(pos.X); positions.Add(pos.Y); positions.Add(pos.Z); Vector2 tc = inTexcoords[0]; texcoords.Add(tc.X); texcoords.Add(tc.Y); indices.Add(nextIdx); ++nextIdx; } reader.Close(); return loader.loadToVAO(positions.ToArray(), texcoords.ToArray(), indices.ToArray()); } } } } } And It have tried other method but it can't show for me.  I am mad now. Because any OpenTK developers won't help me.
      Please help me how do I fix.

      And my download (mega.nz) should it is original but I tried no success...
      - Add blend source and png file here I have tried tried,.....  
       
      PS: Why is our community not active? I wait very longer. Stop to lie me!
      Thanks !

      If I get the best people together for a team, everything should be possible.
       
       
      What i need:
      - Programmer c++
      - Unity / Unreal - we must check whats possible, please share your experience with me.
      - Sculpter, 3D Artist
      - Animator
      - Marketing / Promotion 
       
       
      What i do:
      - Studio Owner
      - Director
      - Recruit exactly you
      - Sounddesign
      - Main theme composing
      - Vocals
      - Game design
      - Gun, swords, shields and weapon design
      - Character, plants and animal design
       
       
      Please dont ask about the Name of the Game, about Designs or Screenshots.
      The game will be defintitly affected about our and your skills if you join the team.
       
       
      Planned for the big Game:
      - 1st person shooter
      - online multiplayer
      - character manipulation
      - complete big open world with like lifetime actions and reactions
      - gunstore with many items to buy
      - many upgrades for players
      - specials like mini games
       
      So if you are interested in joining a team with a nearly complete game idea, contact me now and tell me what you can do.

      I wasn't sure if this would be the right place for a topic like this so sorry if it isn't.
      I'm currently working on a project for Uni using FreeGLUT to make a simple solar system simulation. I've got to the point where I've implemented all the planets and have used a Scene Graph to link them all together. The issue I'm having with now though is basically the planets and moons orbit correctly at their own orbit speeds.
      I'm not really experienced with using matrices for stuff like this so It's likely why I can't figure out how exactly to get it working. This is where I'm applying the transformation matrices, as well as pushing and popping them. This is within the Render function that every planet including the sun and moons will have and run.
      if (tag != "Sun") { glRotatef(orbitAngle, orbitRotation.X, orbitRotation.Y, orbitRotation.Z); } glPushMatrix(); glTranslatef(position.X, position.Y, position.Z); glRotatef(rotationAngle, rotation.X, rotation.Y, rotation.Z); glScalef(scale.X, scale.Y, scale.Z); glDrawElements(GL_TRIANGLES, mesh->indiceCount, GL_UNSIGNED_SHORT, mesh->indices); if (tag != "Sun") { glPopMatrix(); } The "If(tag != "Sun")" parts are my attempts are getting the planets to orbit correctly though it likely isn't the way I'm meant to be doing it. So I was wondering if someone would be able to help me? As I really don't have an idea on what I would do to get it working. Using the if statement is truthfully the closest I've got to it working but there are still weird effects like the planets orbiting faster then they should depending on the number of planets actually be updated/rendered.

      Learning game development in Unreal Engine could be a daunting task for someone who don’t know where to start, and a cumbersome process if you don’t organize your progression correctly. One thing commonly known by experienced developers and by people unfamiliar with coding: mastering a development language is a long and difficult task.
      From blueprints to C++ in Unreal Engine
      If you want to learn fast, you need a good learning strategy. Unreal Engine contains a very powerful tool which you can use to learn C++ faster: its blueprint system. Blueprints are extremely easy to learn (and you may already have a good knowledge of them). Thus you can conveniently use them as a guide for writing code in C++. This is the reason why I am writing a tutorial series on how to make the transition from Unreal Engine blueprints to C++.
      Learn and practice C++
      Following this tutorial, you’ll acquire new concepts of C++ programming in every chapter. Then following chapters will give you reasons to reuse and practice those same concepts. There’s no better way to wire you brain.
      Link to the tutorial: [Tutorial] Learn C++ in Unreal Engine 4 by making a powerful camera
      Please do send me as much feedback as you want. I’ll be considering every constructive remarks and taking them into consideration. Your feedback will help me to improve and update the existing chapters and to make the next one better.

sorry but the question is how do I draw a sprite and then wait for  a period of time and then draw another sprite over it.

Which part(s) of what you said are you having problems with?

1) Drawing the sprite.

2) Waiting for a period of time.

3) Drawing another sprite on top of it?

also I want to erase the sprite after I draw it.

This was explained to you in a previous thread you made. Was the explanation not clear? If so, what was unclear about it?

auto elapsed = timeStampNow - timeStampPrevious;

I get an error with the minus sign(-) no operand matches these operators
