• How can I link to callback functions in Lua such that the callbacks will be updated when the scripts are reloaded?

  - by Raptormeat

  I'm implementing Lua scripting in my game using LuaBind, and one of the things I'm not clear on is the logistics of reloading the scripts live ingame. Currently, using the LuaBind C++ class luabind::object, I save references to Lua callbacks directly in the classes that use them. Then I can use luabind::call_function using that object in order to call the Lua code from the C++ code. I haven't tested this yet, but my assumption is that if I reload the scripts, then all the functions will be redefined, BUT the references to the OLD functions will still exist in the form of the luabind::object held by the C++ code. I would like to be able to swap out the old for the new without manually having to manage this for every script hook in the game. How best to change this so the process works? My first thought is to not save a reference to the function directly, but maybe save the function name instead, and grab the function by name every time we want to call it. I'm looking for better ideas!

• Avoid overwriting all the methods in the child class

  - by Heckel

  The context I am making a game in C++ using SFML. I have a class that controls what is displayed on the screen (manager on the image below). It has a list of all the things to draw like images, text, etc. To be able to store them in one list I created a Drawable class from which all the other drawable class inherit. The image below represents how I would organize each class. Drawable has a virtual method Draw that will be called by the manager. Image and Text overwrite this method. My problem is that I would like Image::draw method to work for Circle, Polygon, etc. since sf::CircleShape and sf::ConvexShape inherit from sf::Shape. I thought of two ways to do that. My first idea would be for Image to have a pointer on sf::Shape, and the subclasses would make it point onto their sf::CircleShape or sf::ConvexShape classes (Like on the image below). In the Polygon constructor I would write something like ptr_shape = &polygon_shape; This doesn't look very elegant because I have two variables that are, in fact, just one. My second idea is to store the sf::CircleShape and sf::ConvexShape inside the ptr_shape like ptr_shape = new sf::ConvexShape(...); and to use a function that is only in ConvexShape I would cast it like so ((sf::ConvexShape*)ptr_shape)->convex_method(); But that doesn't look very elegant either. I am not even sure I am allowed to do that. My question I added details about the whole thing because I thought that maybe my whole architecture was wrong. I would like to know how I could design my program to be safe without overwriting all the Image methods. I apologize if this question has already been asked; I have no idea what to google.

• Calculate travel time on road map with semaphores

  - by Ivansek

  I have a road map with intersections. At intersections there are semaphores. For each semaphore I generate a red light time and green light time which are represented with syntax [R:T1, G:T2], for example: 119 185 250 A ------- B: [R:6, G:4] ------ C: [R:5, G:5] ------ D I want to calculate a car travel time from A - D. Now I do this with this pseudo code: function get_travel_time(semaphores_configuration) { time = 0; for( i=1; i<path.length;i++) { prev_node = path[i-1]; next_node = path[i]); cost = cost_between(prev_node, next_node) time += (cost/movement_speed) // movement_speed = 50px per second light_times = get_light_times(path[i], semaphore_configurations) lights_cycle = get_lights_cycle(light_times) // Eg: [R,R,R,G,G,G,G], where [R:3, G:4] lights_sum = light_times.green_time+light_times.red_light; // Lights cycle time light = lights_cycle[cost%lights_sum]; if( light == "R" ) { time += light_times.red_light; } } return time; } So for distance 119 between A and B travel time is, 119/50 = 2.38s ( exactly mesaured time is between 2.5s and 2.6s), then we add time if we came at a red light when at B. If we came at a red light is calculated with lines: lights_cycle = get_lights_cycle(light_times) // Eg: [R,R,R,G,G,G,G], where [R:3, G:4] lights_sum = light_times.green_time+light_times.red_light light = lights_cycle[cost%lights_sum]; if( light == "R" ) { time += light_times.red_light; } This pseudo code doesn't calculate exactly the same times as they are mesaured, but the calculations are very close to them. Any idea how I would calculate this?

• Two graphical entities, smooth blending between them (e.g. asphalt and grass)

  - by Gabriel Conrad

  Supposedly in a scenario there are, among other things, a tarmac strip and a meadow. The tarmac has an asphalt texture and its model is a triangle strip long that might bifurcate at some point into other tinier strips, and suppose that the meadow is covered with grass. What can be done to make the two graphical entities seem less cut out from a photo and just pasted one on top of the other at the edges? To better understand the problem, picture a strip of asphalt and a plane covered with grass. The grass texture should also "enter" the tarmac strip a little bit at the edges (i.e. feathering effect). My ideas involve two approaches: put two textures on the tarmac entity, but that involves a serious restriction in how the strip is modeled and its texture coordinates are mapped or try and apply a post-processing filter that mimics a bloom effect where "grass" is used instead of light. This could be a terrible failure to achieve correct results. So, is there a better or at least a more obvious way that's widely used in the game dev industry?

• Making retro games: Any good known game architectures?

  - by A.Quiroga

  I'm trying to do a remake of Snowbros . I'm doing it using libgdx but at each time i must try to thought how things got done . For example the physics of the jump and collisions . It seams to be time perfect , but i use the deltaTime to try to aproximate the value in game . I think in this case maybe its using some calcs with processor Hz , but i don't know. Then the simple question , is there any resources of how did they programm this games? Or any idea of the simple ideas repeated each game to game in the old style retro games.

• Hashing 3D position into 2D position

  - by notabene

  I am doing volumetric raycasting and curently working on depth jitter. I have 3D position on ray and want to sample 2D noise texture to jitter the depth. Function for converting (or hashing) 3D position to 2D have to produce absolutely different numbers for a little changes (especialy because i am sampling in texture space so sample values differs very very little) and have to be "shader-wise" - so forget about branches, cycles etc. I'm looking forward for yours nice and fast solutions.

• Is it considered poor programming to do this with xna components?

  - by Rob

  I created my own Menu System that is event driven. In order to have a loading screen and multithreaded loading to work, I devised this sort of implementation: //Let's check if the game is done loading. if (_game != null) { _gameLoaded = _game.DoneLoading; } //This means the game is loading still, //therefore the loading screen should be active. if (!_gameLoaded && _gameActive) { _gameScreenList[2].UpdateMenu(); } //The loading screen was selected. if (_gameScreenList[2].CurrentState == GameScreen.State.Shown && !_gameActive) { Components.Add(_game = new ParadoxGame(this)); _game.Initialize(); //Initializes the Game so that the loading can begin. _gameActive = true; } In the XNA Game Component that contains the actual game, in the LoadContent method I simply created a new Thread that calls another method ThreadLoad that has all the actual loading. I also have a boolean variable called DoneLoading in the XNA Game Component that is set to true at the end of the ThreadLoad. I am wondering if this is a poor implementation.

• Finding the shorter turning direction towards a target

  - by A.B.

  I'm trying to implement a type of movement where the object gradually faces the target. The problem I've run into is figuring out which turning direction is faster. The following code works until the object's orientation crosses the -PI or PI threshold, at which point it will start turning into the opposite direction void moveToPoint(sf::Vector2f destination) { if (destination == position) return; auto distance = distanceBetweenPoints(position, destination); auto direction = angleBetweenPoints(position, destination); /// Decides whether incrementing or decrementing orientation is faster /// the next line is the problem if (atan2(sin(direction - rotation), cos(direction - rotation)) > 0 ) { /// Increment rotation rotation += rotation_speed; } else { /// Decrement rotation rotation -= rotation_speed; } if (distance < movement_speed) { position = destination; } else { position.x = position.x + movement_speed*cos(rotation); position.y = position.y + movement_speed*sin(rotation); } updateGraphics(); } 'rotation' and 'rotation_speed' are implemented as custom data type for radians which cannot have values lower than -PI and greater than PI. Any excess or deficit "wraps around". For example, -3.2 becomes ~3.08.

• Jittery Movement, Uncontrollably Rotating + Front of Sprite?

  - by Vipar

  So I've been looking around to try and figure out how I make my sprite face my mouse. So far the sprite moves to where my mouse is by some vector math. Now I'd like it to rotate and face the mouse as it moves. From what I've found this calculation seems to be what keeps reappearing: Sprite Rotation = Atan2(Direction Vectors Y Position, Direction Vectors X Position) I express it like so: sp.Rotation = (float)Math.Atan2(directionV.Y, directionV.X); If I just go with the above, the sprite seems to jitter left and right ever so slightly but never rotate out of that position. Seeing as Atan2 returns the rotation in radians I found another piece of calculation to add to the above which turns it into degrees: sp.Rotation = (float)Math.Atan2(directionV.Y, directionV.X) * 180 / PI; Now the sprite rotates. Problem is that it spins uncontrollably the closer it comes to the mouse. One of the problems with the above calculation is that it assumes that +y goes up rather than down on the screen. As I recorded in these two videos, the first part is the slightly jittery movement (A lot more visible when not recording) and then with the added rotation: Jittery Movement So my questions are: How do I fix that weird Jittery movement when the sprite stands still? Some have suggested to make some kind of "snap" where I set the position of the sprite directly to the mouse position when it's really close. But no matter what I do the snapping is noticeable. How do I make the sprite stop spinning uncontrollably? Is it possible to simply define the front of the sprite and use that to make it "face" the right way?

• 2D Side scroller collision detection

  - by Shanon Simmonds

  I am trying to do some collision detection between objects and tiles, but the tiles do not have there own x and y position, they are just rendered to the x and y position given, there is an array of integers which has the ids of the tiles to use(which are given from an image and all the different colors are assigned different tiles) int x0 = camera.x / 16; int y0 = camera.y / 16; int x1 = (camera.x + screen.width) / 16; int y1 = (camera.y + screen.height) / 16; for(int y = y0; y < y1; y++) { if(y < 0 || y >= height) continue; // height is the height of the level for(int x = x0; x < x1; x++) { if(x < 0 || x >= width) continue; // width is the width of the level getTile(x, y).render(screen, x * 16, y * 16); } } I tried using the levels getTile method to see if the tile that the object was going to advance to, to see if it was a certain tile, but, it seems to only work in some directions. Any ideas on what I'm doing wrong and fixes would be greatly appreciated. What's wrong is that it doesn't collide properly in every direction and also this is how I tested for a collision in the objects class if(!level.getTile((x + xa) / 16, (y + ya) / 16).isSolid()) { x += xa; y += ya; } EDIT: xa and ya represent the direction as well as the movement, if xa is negative it means the object is moving left, if its positive it is moving right, and same with ya except negative for up, positive for down.

• Interpolation between two 3D points?

  - by meds

  I'm working with some splines which define a path a character follows (you can see a gameplay video here to get a better understanding of what's going on: http://www.youtube.com/watch?v=BndobjOiZ6g). Basically the characters 'forward' look direction is set to the 'forward' direction of the spline and when players tilt their phone left and right the character is strafed along its 'right' coordinate. The issue with this is (rather obviously) in performance, interpolating over a spline to find the nearest position and tangent relative to the player is an incredibly costly operation. To get by this I cache a finite number of positions in what I call 'SplineDetails', the class is as follows: public class SplineDetails { public SplineDetails() { Forward = Vector3.forward; Position = Vector3.one * float.MaxValue; Alpha = -1; } public float Alpha; // [0,1] measured along length of spline where 0 is the initial point and 1 is the end point of the spline public Vector3 Position; // the point of the spline at this alpha public Vector3 Forward; // the forward tangent of the spline at this alpha } I populate this with say 30 coordinates and I can give a rough estimate of a coordinate and 'forward' based on a position past in. It's not as accurate but it's much faster. But now I'd like to make the system work better by estimating positions and 'forward' directions by interpolating between two of the cached points though I'm stuck trying to figure out some logic. My first problem is, how can I determine between which two points the object is? Given each point can be placed at different intervals along the spline it could mean that two points in front or behind the object can be closer to the object. The other problem is to figure out the proportion between the two paths it's between, i.e. if there is a point a at coordinate (0,0,0) and point b at coordinate (1,0,0) if the object is at position (0.5,0,0) then the result it should give is '0.5' (as it is equal distance away from point a and point b). That's a simple example, but what if the object is at coordinate (0.5,3,0) for example?

• Draw Cards and Eliminate Cards Problem

  - by Jen

  I am having a problem in this question. I want a system inside a game wherein the player draws 2 cards randomly, and the enemy draws 2 cards randomly. Then, what the program does is to print out to the console the cards the player draw and the enemy's. The cards should not conflict and must not be the same. Then lastly, the program prints out the card that was not drawn by both the player and the enemy. Here's how I did it but it was lengthy and full of errors: import java.util.Random; public class Draw { public static Random random = new Random(); public static String cards[] = {"Hall", "Kitchen", "Billiard", "Study", "Pool"}; public static int playercounter; public static int enemycounter; public static String playercardA = null; public static String playercardB = null; public static String enemycardA = null; public static String enemycardB = null; public String lastcard = null; public static void playercardAdraw() { playercounter = random.nextInt(5); playercardA = cards[playercounter]; } public static void playercardBdraw() { playercounter=random.nextInt(5); playercardB= cards[playercounter]; if (playercardB==playercardA || playercardB == enemycardA || playercardB == enemycardB) { return; } } public static void enemycardAdraw () { enemycounter = random.nextInt(5); enemycardA=cards[enemycounter]; if (enemycardA == playercardA || enemycardA == playercardB) { return; } } public static void enemycardBdraw () { enemycounter = random.nextInt(5); enemycardB=cards[enemycounter]; if (enemycardB == playercardA || enemycardB == playercardB || enemycardB == enemycardA) { return; } } public static void main (String args []) { System.out.println("Starting to draw..."); System.out.println("Player's Turn: "); playercardAdraw(); System.out.println("Player's first card: " + playercardA); playercardBdraw(); System.out.println("Player's second card: " + playercardB); System.out.println("Enemy's Turn: "); enemycardAdraw(); System.out.println("Enemy's first card: " + enemycardA); enemycardBdraw(); System.out.println("Enemy's Second card: " + enemycardB); } }

• iOS Game that Runs Continuously in Background

  - by user2913669

  I'm trying to understand the most logical way of creating an iOS game that runs continuously in the background. For example.. you have tower and enemy waves. The game has endless enemy waves even when the game exits. When you open the game again, it will retrieve the data that occurred when the app was closed. I assume a database on a server would be the best solution. The values continuously increment on the server. The game connects to the server and retrieves the specific user's updated game data.

• What are the factors that determine the default frequency of a shader call?

  - by user827992

  After i have been played for some days with various vertex and fragments shaders seems clear to me that this programs are called by the GPU at every and each rendering cycle, the problem is that I can't really quantify this frequency and I can't tell if is based on some default values or not because I don't have a big collection of hardware right now to do extensive tests. For what i know the answer could be really trivial like "it's the same of the refresh rate of your monitor", but i would like some good answers on that to be clear on this. For instance looks really odd to me that all the techniques used to control the amount of FPS that i have seen until now uses a call for the OpenGL function glutGet(GLUT_ELAPSED_TIME) to retrieve a value in ms about when the rendering started but I have to relies on the CPU to do the math. Why I can't set an FPS value in OpenGL if OpenGL clearly has a counter and a timer/clock? PS I'm referring to OpenGL 3.0+

• XNA 2D Board game - trouble with the cursor

  - by Adorjan

  I just have started making a simple 2D board game using XNA, but I got stuck at the movement of the cursor. This is my problem: I have a 10x10 table on with I should use a cursor to navigate. I simply made that table with the spriteBatch.Draw() function because I couldn't do it on another way. So here is what I did with the cursor: public override void LoadContent() { ... mutato.Position = new Vector2(X, Y); //X=103, Y=107; mutato.Sebesseg = 45; ... mutato.Initialize(content.Load<Texture2D>("cursor"),mutato.Position,mutato.Sebesseg); ... } public override void HandleInput(InputState input) { if (input == null) throw new ArgumentNullException("input"); // Look up inputs for the active player profile. int playerIndex = (int)ControllingPlayer.Value; KeyboardState keyboardState = input.CurrentKeyboardStates[playerIndex]; if (input.IsPauseGame(ControllingPlayer) || gamePadDisconnected) { ScreenManager.AddScreen(new PauseMenuScreen(), ControllingPlayer); } else { // Otherwise move the player position. if (keyboardState.IsKeyDown(Keys.Down)) { Y = (int)mutato.Position.Y + mutato.Move; } if (keyboardState.IsKeyDown(Keys.Up)) { Y = (int)mutato.Position.Y - mutato.Move; } if (keyboardState.IsKeyDown(Keys.Left)) { X = (int)mutato.Position.X - mutato.Move; } if (keyboardState.IsKeyDown(Keys.Right)) { X = (int)mutato.Position.X + mutato.Move; } } } public override void Draw(GameTime gameTime) { mutato.Draw(spriteBatch); } Here's the cursor's (mutato) class: using System; using System.Collections.Generic; using System.Linq; using System.Text; using Microsoft.Xna.Framework; using Microsoft.Xna.Framework.Graphics; namespace Battleship.Components { class Cursor { public Texture2D Cursortexture; public Vector2 Position; public int Move; public void Initialize(Texture2D texture, Vector2 position,int move) { Cursortexture = texture; Position = position; Move = move; } public void Update() { } public void Draw(SpriteBatch spriteBatch) { spriteBatch.Draw(Cursortexture, Position, Color.White); } } } And here is a part of the InputState class where I think I should change something: public bool IsNewKeyPress(Keys key, PlayerIndex? controllingPlayer, out PlayerIndex playerIndex) { if (controllingPlayer.HasValue) { // Read input from the specified player. playerIndex = controllingPlayer.Value; int i = (int)playerIndex; return (CurrentKeyboardStates[i].IsKeyDown(key) && LastKeyboardStates[i].IsKeyUp(key)); } } If I leave the movement operation like this it doesn't have any sense: X = (int)mutato.Position.X - mutato.Move; However if I modify it to this: X = (int)mutato.Position.X--; it moves smoothly. Instead of this I need to move the cursor by fields (45 pixels), but I don't have any idea how to manage it.

• How do you prevent inflation in a virtual economy?

  - by Tetrad

  With your typical MMORPG, players can usually farm the world for raw materials essentially forever. Monsters/mineral veins/etc are usually on some respawn timer so, other than time, there really isn't a good way to limit the amount of new currency entering the system. So that really only leaves money sinks to try to take money out of the system. What are some strategies to prevent inflation of the in-game currency?

• Is there a good book or articles to learn about 2D Game Design and Effects?

  - by user28015

  I am not looking for a read how to develop games and how to implement one. I am looking for a general about possible effects in 2D Games and about general design of modern 2D gaming. I have programmed several smaller games over the years and also read books like "Golden Rules of Game Programming" by Martin Bronwlo. So I know how to implement games. What I am looking for are 2 things: Finishing touches such as effects like explosions, particles etc. Not how to make them, but how to design them so it looks right and cool. How to make a 2D game feel "more right" so that users get a satisfying gaming experience. I played a lot of 2D games but I could use some more advice.

• How can I get accurate collision resolution on the corners of rectangles?

  - by ssb

  I have a working collision system implemented, and it's based on minimum translation vectors. This works fine in most cases except when the minimum translation vector is not actually in the direction of the collision. For example: When a rectangle is on the far edge on any side of another rectangle, a force can be applied, in this example down, the pushes one rectangle into the other, particularly a static object like a wall or a floor. As in the picture, the collision is coming from above, but because it's on the very edge, it translates to the left instead of back up. I've searched for a while to find an approach but everything I can find deals with general corner collisions where my problem is only in this one limited case. Any suggestions?

• Collision checking problem on a Tiled map

  - by nosferat

  I'm working on a pacman styled dungeon crawler, using the free oryx sprites. I've created the map using Tiled, separating the floor, walls and treasure in three different layers. After importing the map in libGDX, it renders fine. I also added the player character, for now it just moves into one direction, the player cannot control it yet. I wanted to add collision and I was planning to do this by checking if the player's new position is on a wall tile. Therefore as you can see in the following code snippet, I get the tile type of the appropriate tile and if it is not zero (since on that layer there is nothing except the wall tile) it is a collision and the player cannot move further: final Vector2 newPos = charController.move(warrior.getX(), warrior.getY()); if(!collided(newPos)) { warrior.setPosition(newPos.x, newPos.y); warrior.flip(charController.flipX(), charController.flipY()); } [..] private boolean collided(Vector2 newPos) { int row = (int) Math.floor((newPos.x / 32)); int col = (int) Math.floor((newPos.y / 32)); int tileType = tiledMap.layers.get(1).tiles[row][col]; if (tileType == 0) { return false; } return true; } The character only moves one tile with this code: If I reduce the col value by two it two more tiles. I think the problem will be around indexing, but I'm totally confused because the zero in the coordinate system of libGDX is in the bottom left corner of the screen, and I don't know the tiles array's indexing is similair or not. The size of the map is 19x21 tiles and looks like the following (the starting position of the player is marked with blue:

• SFML: Monster following player on a straight line

  - by user3504658

  I've searched for this and found a few topics , usually they used a function normalize and using simple vector subtracting which is ok , but how should I do it in sfml ? Instead of using: Movement = p.position() - m.position(); p is the player and m is the monster I used something like this to move on a straight line: sf::Vector2f Tail(0,0); if((mPlayer.getPosition().y - mMonster.GetInstance().getPosition().y) >= (mPlayer.getPosition().x - mMonster.GetInstance().getPosition().x)){ //sf::Vector2f Tail(0,0); Tail.x = mPlayer.getPosition().x - mMonster.GetInstance().getPosition().x; } else if((mPlayer.getPosition().y - mMonster.GetInstance().getPosition().y) <= (mPlayer.getPosition().x - mMonster.GetInstance().getPosition().x)){ //sf::Vector2f Tail(0,0); Tail.y = mPlayer.getPosition().y - mMonster.GetInstance().getPosition().y; } if(!MonsterCollosion()) mMonster.Move(Tail * (TimePerFrame.asSeconds() * 1/2 ) ); It works ok if the the height = the width for the game window, although I think it's not the best looking game when it comes to a moving monster, since it starts fast and then it gets slower so what do you guys advise me to do ?

• How can I mark a pixel in the stencil buffer?

  - by János Turánszki

  I never used the stencil buffer for anything until now, but I want to change this. I have an idea of how it should work: the gpu discards or keeps rasterized pixels before the pixel shader based on the stencil buffer value on the given position and some stencil operation. What I don't know is how would I mark a pixel in the stencil buffer with a specific value. For example I draw my scene and want to mark everything which is drawn with a specific material (this material could be looked up from a texture so ideally I should mark the pixel in the pixel shader), so that later when I do some post processing on my scene I would only do it on the marked pixels. I didn't find anything on the internet besides how to set up a stencil buffer and explaining the different stencil operations. I was expecting to find some System-Value semantics like SV_Depth to write to in the pixel shader (because the stencil buffer shares the same resource with the depth buffer in D3D11), but there is no such thing on MSDN. So how should I do this? If I am misunderstanding something please help me clear that up.

• Tips on how to notify a user of new features in your game

  - by brent777

  I have noticed a problem when releasing new features for a game that I wrote for Android and published on Google Play Store. Because my game is "stage-based" - and not a game like Hay Day, for example, where users will just go into the game every day since it can't really be finished - my users are not aware of new features that I release for the game. For example, if I publish a new version of my game and it contains a couple new stages, most of their devices will just auto-update the game and they don't even notice this and think to check out what's new. So this is why an approach like popping open a dialog that showcases the new feature(s) when they open the game for the first time after the update was done is not really sufficient. I am looking for some tips on an approach that will draw my users back into the game and then they could read more detail about new features on such a dialog. I was thinking of something like a notification that tells them to check out the new features after an update is done but I am not sure if this is a good idea. Any suggestions to help me solve this problem would be awesome.

• Offset Forward vector of object based on Rotation

  - by Taylor

  I'm using the Bullet 3D physics engine in a iOS application running openGL ES 1.1 Currently I'm accepting info from the gyroscope to allow the user to "look around" a 3d world that follows a bouncing ball (note: it only takes in the yaw to look around 360 degrees). Im also accepting information from the accelerometer based on the tilt to push the ball. As of right now, to move forward, the user tilts the devise forward (using the accelerometer); to move to the right, the user tilts the devise to the right and so on. The forward vector is currently along it's local Z-axis. The problem is that I want to change the ball bounce based on where the user has changed the view. If I change the view, the ball bounces in the fixed direction. I want to change the forward facing direction so that when a user changes the view (say to the look at the right of the world, the user rotates the device), tilting the devise forward will result in a forward force in that direction. Basically, I want the forward vector to take the rotation into consideration. Sorry if I didn't explain the issue well enough, its kind of confusing to write down.

• MCP 1.7.10 Java class navigation

  - by Elias Benevedes

  So, I'm new to the Minecraft modding community and trying to understand where to start. I've attempted to do it before, but dropped it to the complexity of starting and the lack of a site like this to help (Mind that I'm also semi-new to Java, but have worked extensively in Javascript and Python. I understand how Java is different from the two). I have downloaded MCP 9.08 (Decompiles 1.7.10), and decompiled Minecraft. I'm looking to mod client, so I didn't supply it with a server jar. Everything seemed to work fine in decompile (Only error was it couldn't find the server jar). I can find my files in /mcp908/src/minecraft/net/minecraft. However, if I open up one of the classes in, say, block, I see a bunch of variables starting with p_ and ending with _. Is there any way to make these variables more decipherable, to understand what's going on so I can learn by example? Thank you.
