• What do I need to get a job with a major game company?

  - by MahanGM

  I've been recently working with DirectX and getting familiar with game engines, sub-systems and have done game development for the last 5 years. I have a real question for those whom have worked in larger game making companies before. How is it possible to get to into these big game creators such as Ubisoft, Infinity Ward or EA. I'm not a beginner in my field and I'm going to produce a real nice 2D platform with my team this year, which is the result of 5 years 2D game creation experience. I'm working with prepared engines such as Unity3D or Game Maker software and using .Net with C# to write many tools for our production and proceeding in my way but never had a real engine programming experience 'till now. I'm now reading good books around this topic but I wanted to know: Is it possible to become an employee in big game company by just reading books? I mean beside having an active mind and new ideas and being a solution solver.

• How to integrate game logic in game engines

  - by MahanGM

  Recently I'm working on a 2d game engine example in .Net with C#. My main problem is that I can't figure out how I should include the game logic within the game. Currently I have a base engine which is a set of classes that they are running sub-systems like Render, Sound, Input and Core functionality. There is an editor which helps the user to add resources, build levels, write scripts and other stuffs. I came up with an idea to use Reflection and CSharpCodeProvider from my editor to compile the written code. This way I can get an executable of my product too. This way is quite well but I would like to know what's really the solution and architecture to do this. My engine's role is 2d platform. The scripting language is C# right now because I can't consist any other embeddable language for now. The game needs compilation and CSharpCodeProvider is the only way for me to do it meantime.

• How to bind std::map to Lua with LuaBind

  - by MahanGM

  Is this possible in lua to achieve? player.scripts["movement"].properties["stat"] = "stand" print (player.scripts["movement"].properties["stat"]) I've done getter method in c++ with this approach: luabind::object FakeScript::getProp() { luabind::object obj = luabind::newtable(L); for(auto i = this->properties.begin(); i != this->properties.end(); i++) { obj[i->first] = i->second; } return obj; } But I'm stuck with setter. The first line in lua code which I'm trying to set value "stand" for key "stat" is not going to work and it keep redirecting me to the getter method. Setter method only works when I drop ["stat"] from properties. I can do something like this for setter in my script: player.scripts["movement"].properties = {stat = "stand"} But this isn't what I want because I have to go through my real keys in c++ to determine which key is placed in setter argument table value. This is my map in class: std::map<std::string, std::string> properties;

• how to link a c++ object to a local variable in Lua

  - by MahanGM

  I'm completing my scripting interface with Lua, but recently I've stuck at some point. I have several functions for my Entitiy events like Update(). I have a function called create_entitiy() which instantiate a new entity from a given entity index: function Update() local bullet = create_entity(0, 0, "obj_bullet") end create_entity returns a table which is the properties of the created entity. Now how can I make a connection between bullet variable and my newly created object? Right now for previously added objects to the scene, I simply set a global table for each of them and then after every call to Update(), I go through registered names to find object tables and perform new changes. Like the one below: function Update() if keyboard_key_press(vk_right) then obj_player.x += 3 end I can get obj_player table because I know its name from C++, plus I can get it as a global table and simply reach for the first instance named obj_player. Is there any solution for me to make bullet variable act like this? I was thinking to get all local variables in Update() function and check for every one to see if is it table and it has an unique field attached to it like id, this way I can determine that this is an object table and do the rest of the process. By the way, is this interface going to work easier with luaBind if I implement it? Bottom line: How can I make a local variable in Lua that receives a table from create_entity function and track that local variable to capture it from C++. e. g. function Update() local bullet = create_entity(0, 0, "obj_bullet") bullet.x = 10 <== Commit a change in table end Now I want to get variable bullet from C++. And it's not just this variable, there might be a ton of these local variables with different names.

• How to set orthgraphic matrix for a 2d camera with zooming?

  - by MahanGM

  I'm using ID3DXSprite to draw my sprites and haven't set any kind of camera projection matrix. How to setup an orthographic projection matrix for camera in DirectX which it would be able to support zoom functionality? D3DXMATRIX orthographicMatrix; D3DXMATRIX identityMatrix; D3DXMatrixOrthoLH(&orthographicMatrix, nScreenWidth, nScreenHeight, 0.0f, 1.0f); D3DXMatrixIdentity(&identityMatrix); device->SetTransform(D3DTS_PROJECTION, &orthographicMatrix); device->SetTransform(D3DTS_WORLD, &identityMatrix); device->SetTransform(D3DTS_VIEW, &identityMatrix); This code is for initial setup. Then, for zooming I multiply zoom factor in nScreenWidth and nScreenHeight.
