If you want to make a full-screen application without TitleBar then you will not receive keystrokes. The error was on Xubuntu 16.04 beta branch of the engine

Hello dear developers. I have noticed that for the export tools are working very slowly. (I am working on linux) If you can, you remake them faster algorithm or add multicore performance mode. If you do not have time, I'm ready to write these tools (if you show the source or tell us about the structure of their formats, and interaction with tools)

The engine has a small capacity in comparison with others. The bad development policy, where everything depends on the sale Workshop (It makes you wonder about the wisdom of using LW

Then I'll write more (as return for their workplace)

Well, I'm on Ubuntu 14.04 (750M - GPU) the game has a large consumption of VRAM (~ 1500Mb) Screen resolution (1920x1080) Statistics: In the game menu: 30 FPS. 125 Mb VRAM. The game (Entry Level): 15 FPS. 1125 Mb VRAM. In the woods: 7 FPS. 1450VRAM

Perhaps few people would write plugins for LeadWerks. But let's say, if a person is working on a serious project in LW then it will be easier to sharpen the engine for their purpose. For example, in LW bad editor primitives, poor editor terrain (although it is possible to alter and by changing the shader processing), and more. For example, to make the roads or rivers editor (if waiting for the official implementation, this can take a long time, but to do a simple tool can be quickly (I wrote this, but visualization was only in the game -. Which is very inconvenient)

As you see, by adding in LW the following functionality: -A set of functions for rendering in the Editor (Draw for example lines, text, etc.) -Ability to create/ edit tools or entities

Hello everybody. Today I probably will start the first lesson dedicated to developing games with LeadWerks Game Engine 4.1. Table of contents: Introduction Requirements Project preparation Setting up the project Level creation (Prototype) Ball Script Introduction This lesson is to create a game where the main character is a ball (or other primitive). By the way, there is such a lesson ( "Marble Game") in the official documentation. Requirements Before we begin, I would say the main requirements for the correct execution of the lesson: You must dial the code themselves. This will allow you to understand the basic design principles. Carefully read the text of the lesson and follow all the steps. It is very important. Treat with understanding the author. I am a simple man, and I can make mistakes. Well. Now you can start a lesson. Project preparation Start LeadWerks 4.1 and open the "Project Manager" (how?) For the tutorial, I'll use an empty project ( "Blank Project"). The name you can choose any, I chose "BallGame". After the final creation, we make some modifications to the workspace. We need to add some starter content. For the tutorial, I'll take it from a template "Advanced First-Person Shooter". We need a folder with materials. Open this folder ({Steam Folder}/steamapps/common/Leadwerks/Templates/Advanced First-Person Shooter/) (If you change the directory LW then open it) And copy the folder "Materials" folder in your workspace. Well done if you have completed all the stages of preparation. It remains only to make a game ))) Setting up the project Open your workspace (project) in LW. Now we'll do a few simple actions to configure our project. We will make a simple splash screen and other simple decorations. Open the file "Main.lua" ( "Scripts / Main.lua") in the script editor (how?) Now we have to modify the "Main.lua". I will not talk about work with Lua principles in LW (You can read about this in the Tutorial). I'll just write code and specify where to insert it (I'll refer to a reading material about this) All functions that are available to us, you can find in the API. To implement a simple splash screen, we need the following themes: Context Context::DrawText Context::GetCurrent Context::Sync Time Time::Delay Window Window::GetHeight Window::GetWidth Lua with LW (Steam) A lot of material had accumulated. But not everything is so terrible. Will definitely start writing screen) Go to the 20th line of the code. It is especially this place? It's simple. All code up to this initialisere LW, and already runs code after the first level and run all in normal mode. Now I will write all of the code that you have to understand yourself to write, and later I will comment on it. --simple splash screen (only example) tempFont = context:GetFont() --Current Font/ We save for restore after display local font = Font:Load("Fonts/Arial.ttf",36) --Font for display context:SetFont(font) font:Release() local X = window:GetWidth() * 0.45 --the definition of the center of Width local Y = window:GetHeight() *0.5 --the definition of the center of Height( local A = 0 --Alpha local AStep = 0.005 --increment step local TimeScreen = 2.5 --Time in sec for display TimeScreen = TimeScreen * 1000 context:SetBlendMode(Blend.Alpha) context:SetColor(1,1,1,0) --Start Color while window:KeyDown(Key.Space)==false do --Space for skip Time:Step() context:DrawText(title .." with Leadwerks",X,Y) --Text context:SetColor(A,A,A,1) Time:Delay(TimeScreen / (1 / AStep)) A = A + AStep context:Sync(false) --Out on the screen if (A >= 1) then break end end context:SetColor(1,1,1,1) context:SetScale(1,1) context:SetFont(tempFont) tempFont:Release() The result is bad. But this is only a simple example. At desire it is possible to complicate the code and will be all good) Now let's do the automatic detection of screen resolution (run full screen) Go to line 10. There will be a similar piece of code window=Window:Create(title,0,0,System:GetProperty("screenwidth","1024"),System:GetProperty("screenheight","768"),windowstyle) The values of the parameters screenwidth and screenheight define the starting desktop resolution. We can ask the system to know the current desktop resolution. insert before line 10 the following code: screen = System:GetGraphicsMode(System:CountGraphicsModes()-1) screenwidth = screen.x screenheight = screen.y Now modify the line window=Window:Create(title,0,0,System:GetProperty("screenwidth","1024"),System:GetProperty("screenheight","768"),windowstyle) in the following line window=Window:Create(title,0,0,System:GetProperty("screenwidth",screenwidth),System:GetProperty("screenheight",screenheight),windowstyle) And 9 line write "System:GetProperty("fullscreen",1)" instead of "System:GetProperty("fullscreen")" I know that experienced developers will tell you what to do, but we're just learning. In normal projects you can't do that) How much we have done. But even more lies ahead. Level creation (Prototype) In this part of the lesson, I'm not going to tell you anything. A lot of articles on this subject is on the Internet. I'll give a couple of links and it will show a prototype) The appropriate lessons LeadWerks you can find here To build a level, I will use primitives. Character is a ball, the levels are composed of platforms. Here's what I got (Show me what you have left) Are you pleased with the result? If not, then understand that you do not like your level and correct. Level ready. Make the character (ball) Ball Script Read the tutorial Now you have an idea how to do it. And I'll show you my implementation. Create a script of the player (Similar to that of a tutorial) ("Scripts/Player/BallPlayer.lua") It will be the main file for us. Through him we will make the control of the character/ camera / other. I will do as always. Write all the code and tell you how it works. So I'll give links to topics which will include (But will not give references to the functions themselves. You have to find yourself) --Script Settings Script.Mass = 10 --int (MassPlayer) Script.Speed = 25.0 --float (Speed Mul) Script.EnergyToJump = 1500.0 --float (It is for jump) function Script:Start() self.Force = self.Mass * self.Speed --Created Force Multiple self.Direction = Vec3(0,0,0) --Helpfull (Determines where we are going) self.entity:SetMass(self.Mass) --Created Mass --Camera self.camera = Camera:Create() self.camera:SetPosition(self.entity:GetPosition()) self.camera:SetRotation(45, 0, 0) self.camera:Move(0,0, -4) --Light self.light = PointLight:Create() self.light:SetPosition(self.entity:GetPosition()) self.light:SetRange(2) --For Jump self.ETJ = self.EnergyToJump end function Script:UpdateWorld() --The cursor displacement (rotation camera) self.offsetx = window:GetMousePosition().x - window:GetWidth()/2 self.offsety = window:GetMousePosition().y - window:GetHeight()/2 --Camera Rotation with offset self.camera:SetRotation(self.offsety/10 + self.camera:GetRotation().x, self.offsetx/10 + self.camera:GetRotation().y, 0, false) --Generate points for a jump if self.ETJ < self.EnergyToJump then self.ETJ = self.ETJ + self.EnergyToJump * 0.005 end --Camera self.camera:SetPosition(self.entity:GetPosition()) self.camera:Move(0,0, window:GetMousePosition().z - 4) --Light self.light:SetPosition(self.entity:GetPosition()) --Direction for move self.Direction.x = -Math:Sin(self.camera:GetRotation(true).y) self.Direction.z = Math:Cos(self.camera:GetRotation(true).y) --Move if window:KeyDown(Key.W) then self.entity:AddForce(self.Direction * self.Force,true) end if window:KeyDown(Key.A) then self.entity:AddForce(Vec3(self.Direction.z, 0, self.Direction.x) * self.Force * -1 ,true) end if window:KeyDown(Key.D) then self.entity:AddForce(Vec3(self.Direction.z, 0, self.Direction.x) * self.Force,true) end if window:KeyDown(Key.S) then self.entity:AddForce(self.Direction * self.Force * -1 ,true) end --Jump if (self.ETJ - 100) > 0 then if window:KeyDown(Key.Space) then self.ETJ = self.ETJ - 100 self.entity:AddForce(Vec3(0, self.Mass, 0) * self.Force * 0.7 ,true) end end window:SetMousePosition(window:GetWidth()/2, window:GetHeight()/2, 0) end function Script:PostRender(context) context:SetBlendMode(Blend.Alpha) context:SetColor(1,1,1,1) context:DrawText("Energy to jump" .. self.ETJ,2,2) end Apply this script to the ball physics and play. The lesson was over. You made a simple game. Now you can finish the leveling/ points/ achievements to sell on Steam. Here are screenshots of my result: I hope you will find useful this tutorial. In the future, I can tell you other things)

ahaha. Thank you. So I wrote everything correctly)

Xmm. With Ubuntu fps litle( (15-25)

Very poor optimization. My video card is crying. Learn that consumes so much VRAM and optimizes it.

Hello everybody. I first appeared on the website leadwerks, but I've been working a long time with this engine (first seen in 2012, LE2). And in the beginning, I would like to show their achievements in this engine. A little about me. I am 19 years old, live in the cold and harsh Russia (in fact it is not. We have a warm and beautiful country. All this is the stereotype) is a C / C ++ / C # programmer (3 years) and a game developer (5 years) If there is a wish, I can help you answer different questions. Unfortunately it's difficult to communicate in English, but I'll try to help you (for one to learn the language)
