Why does this downscaling algorithm produce artifacts?

由 ▼魔方 西西 提交于 2019-12-12 04:28:51
问题 I have a scaling algorithm which appears to scale the image to the right size, but produces artefacts(slight image corruption) in the right half of the image. As I am inexperienced using pointers, I suspect I may have blundered with my pointer arithmetic! To run the project on OSX: 1. Download from :https://www.dropbox.com/s/myme1z1mkxjwyjf/artifact.zip?dl=0 Open the xcodeproj file found in proj.ios All code that is of relevance, is in HelloWorldScene.cpp In function test(), you can comment

How to add a sprite that is always on the screen in Cocos2d?

由 心不动则不痛 提交于 2019-12-12 02:39:15
问题 I'm doing a platformer game using cocos2d-x v3 in c++, where the maps are usually very large, the visible screen follows the object through the map. Let's say I want to show a sprite in the top right corner of the screen and it would be in this position even when the screen is following the object. Using the object position doesn't do it. Is there a way to show a sprite or whatever in the screen and it would be in the screen even when the screen is moving? Ps. I'm super noob in game

Weird y-position offset using custom frag shader (Cocos2d-x)

由 假如想象 提交于 2019-12-11 01:17:07
问题 I'm trying to mask a sprite so I wrote a simple fragment shader that renders only the pixels that are not hidden under another texture (the mask). The problem is that it seems my texture has its y-coordinate offset after passing through the shader. This is the init method of the sprite (GroundZone) I want to mask: bool GroundZone::initWithSize(Size size) { // [...] // Setup the mask of the sprite m_mask = RenderTexture::create(textureWidth, textureHeight); m_mask->retain(); m_mask-
