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.

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
In the HT for Web , both 3D applications support the display of tree-like structure data, showing different effects, the tree structure on 2D is obvious in the presentation hierarchy, but if the amount of data is large, it seems to be less intuitive, it is difficult to find the specified node, The 3D tree structure on the display with the HT for Web Elastic layout components will be more intuitive, a glance can be the whole tree structure data to see

Very early plan to learn OpenGL, but because the curriculum and learning algorithms occupy the time, has not been able to start, now this time began to make OpenGL, these days are watching "OpenGL into the 8th edition of the Guide," first read GLSL write shader. Here, try a simple small example with a fixed pipeline, and then start the programmable pipeline.This small example is very simple, is to draw a square in the 2D plane, and then move around.Th

The procedure is as follows:
1.Enable 2D Texture first. If it is not enabled, the texture area is black.
Glable (gl_texture_2d)
2.Generate texture
Glgentextures (1, m_ntextureid)
Glbindtexture (1, m_ntextureid)
Glteximage2d (gl_texture_2d, 0, gl_rgba, m_nwidth, m_nheight, 0, gl_rgba, gl_unsigned_byte, m_pdata );

You can also enable the following filtering methods:
