With a simple 2D game case to learn about unity 2D Game development, this article is divided into the following 4 sections.· Create a work layer· Add a static scene· Making 2D Animations· adding Roles and controls· Add 2D effectsThrough this case, we can learn the basic process of unity2d game production, the creation

Guidance: 　　 Introduction 　　 Definition of a point A point can be represented in 2D space as a pair of numbers, one for each of the X and Y axis: 　　 Distance between two points The distance between two points 　　 DX = Ax-bx DY = Ay- Distance = SQRT (dx * dx + dy * Dy) 　　 Definition of a vector A vector can be thought of in two ways: either a point at or a line going from the origin Vectors are often used to describe direction. If we take a

One, CSS3 2D has two properties:(1), transform: The element used for 2D or 3D conversion.(2), Transform-origin: Allows changing the location of the conversion element . Two, CSS3 2D of the transform attribute There are 5 major methods: 1, rotate (angle) Rotation method: Define 2D rotation, the parameters of the method

First, the conversion1, the definition of conversion:1, you can change the shape of the element, position, size.2, there are two types of conversions:A: The element can only change on the x-axis and the y-axis plane. Change shape, size, and position.Example: Panning (move), tilt (skew), rotation (rotate) scaling (scale)3D Conversion: space conversion3. Properties of the transformation:1>,transform Properties (2D conversion, 3D conversion); Co

Android 2D game engine andengine configuration Environment1.2Configuring the Environmentin any programming, some software or hardware support is required. Otherwise, there is no hardware software is impossible to exist, and want to write the corresponding language of the program, which requires the corresponding language library and compiler support. So in the open andengine Game also need these things, and we need the environment have those? This sec

The Unity-2d will not appear in Ubuntu12.10 (with hints at the previous UDS), meaning Ubuntu official will give up Unity-2d. For older devices, you can use the llvmpipe program to ensure Unity compatibility. About Unity-2d: Because Unity must have 3D graphics card support, so some friends without 3D graphics card and friends who use netbook can not use Unity, so

This series is a translation of the introducing Starling PDF, which is reproduced in a log of the Adobe Developer Center, with the address http://www.adobe.com/cn/devnet/flashplayer/articles/ Introducing_starling.htmlStarling is an ActionScript 3 2D framework developed on Stage3D APIs (available for Flash Player 11 and Adobe AIR 3 desktops). Starling is designed for game development, but you can apply it to many other applications. Without involving l

The View matrix of the image camera is also required to calculate

Deep understanding of CSS deformation transform (2d) and csstransform* Directory [1] deformation source [2] deformation function [3] Before multi-value CSS deformation transform is a set of effects. It mainly involves four basic operations: movement, rotation, scaling, and skew. You can also set a matrix to achieve more complex effects. Transform deformation can achieve 2D and 3D effects.

The original text is too long, so the translation and the original text are divided into two parts, mainly about the tile rules of 2D games and the principle of irregular rendering and role collision. Because the development of simple 2D games is too simple, this article attempts to combine different 2D flat games and classify them to list their advantages and di

Quartz 2D IntroductionQuartz 2D is a two-dimensional graphics-drawing engine developed by Apple, which supports both iOS and Mac systems. It is a C-based API framework that provides low level, lightweight, high-fidelity 2D rendering. The work it can accomplish is: Drawing graphics: line \ triangle \ Rectangle \ Circle Arc etc. Draw text Drawing \ Ge

A friend asked me today. A typical example is the blood bar of Characters in the game. The principle is to convert a 3D point into a 2D point, but since NGUI itself is 3D, we need to convert the point under NGUI into a 2D point first, and then convert it into a 3D point. It sounds a bit difficult. It doesn't matter if I directly access the code. Looking at NGUI research that is not clear about screen adapta

Under normal circumstances, just press the Edit Collider button, the mouse stops at the edge of the Polygon Collider 2D, a virtual new vertex will appear, at this point, if you press the mouse, the new vertex is created.But I have a strange situation today is the mouse on the edge of the Polygon Collider 2D, does not appear the virtual new vertex, click does not create a new vertex. Later found that the sca
