问题 I developped a small games like "minecraft". and I'm stuck for a few days on the calculation of the direction of the cursor. Let me explain. I would like to target a cube with my cursor in the middle of the screen and make it disappear with a click. But I do not see any how to recover this information .. Can someone point me to a "sample / tutorial" or explanation please? Thank you very much. My screenShoot picture game : 回答1: I take no credit for most of this--it's what I used in my 3D XNA

问题 I'm trying to create a simple JS game engine on my own. Here's the code for one of the states. var menuState = { //state variables menuBttn: {x: _canvas.width/2, y:_canvas.height/2, img: imageArray[2], over: false, click: function(){changeState(2);}}, preload: function () { }, update: function(){ surface.clearRect(0, 0, _canvas.width, _canvas.height); for (var i = 0; i < menuAssets; i++){ surface.drawImage(menuState.menuBttn.img , menuState.menuBttn.x, menuState.menuBttn.y); console.log

问题 I'm trying to write this tutorial in Pygame(Python) and having problems about holding points between planes. My code is: fiz2.py Vector class: vector.py If you move mouse on the Pygame screen, the planes will rotate. And when the planes are rotating, points are passing through planes and going outside. I tried to fix points' positions on every iteration but they still passed the planes. I have no idea about where should I fix their positions. NOTE: I know my code is a little bit messy, this

问题 I've been asked to sample some data in a .wac file type. I'm not familiar with this standard and there is very little on the internet with regards to this format. I got given the .wav file but I don't think it was converted correctly, in that there was a none existent of the RIFF header so no .wav reader was able to read it. Could anyone therefore shed some light into how I could possibly convert the .wac file into a .wav file? Doing some research, I cannot seem to find a converter tool on

问题 Found a lot of physic engines out there but nothing that fit my needs directly. I try to to find a simple way to push and pull boxes including collision detection which respects the next neighboring mesh hit while moving. Some use cases to understand: All boxes except box 1 are moveable. Push or Pull box 4 to west: Should move box 3 to west on collision. Should make box 3 and 4 not able to move west when box 3 hits box 2. Push 2, 3 or 4 to north: Should stop when it hits box 2, because box 1

问题 This is clearly not a coding problem but the logical one. I am starting to learn how to make a match 3 game. but there is a question rising in my mind. when i will set goal to complete the level, how will i know the goal is achievable ? suppose in a level where i have to collect 5 Red, 12 blue, 9 green objects by matching the same(like farm heros). how would i decide how much moves i need to set to make this goal achievable. i mean it should be challenging but not be impossible. since the

问题 I'm new to game development, SDL and C++. I have been learning with the code here: http://gamedevgeek.com/tutorials/managing-game-states-in-c/ The relevant bit: Multiple states are not only important in demos, but also in games in general. Every game starts off in an introduction state, then moves to a menu of some kind, a finally play begins. When you’re finally defeated, the game moves to a game-over state, usually followed by a return to the menu. In most games it is possible to be in more

问题 I'm trying to implement a simple ECS for my game engine. I know that my implementation is not strictly ECS, but I'm refactoring my code to be more component-based. So far I have the following classes: Entity : it is a container of components, and since I want my entity to have multiple components of the same type, it stores them in a std::map<ComponentID,std::vector<std::unique_ptr<Component>>> . Each component has a unique ID (an unsigned int), that I get from a simple template trick I

问题 I'm new to game development. Currently I'm doing a game for js13kgames contest, so the game should be small and that's why I don't use any of modern popular frameworks. While developing my infinite game loop I found several articles and pieces of advice to implement it. Right now it looks like this: self.gameLoop = function () { self.dt = 0; var now; var lastTime = timestamp(); var fpsmeter = new FPSMeter({decimals: 0, graph: true, theme: 'dark', left: '5px'}); function frame () { fpsmeter
