Perfect pixel collision detection cocos2d

Oct 15,  · 最近在cocos2d forum 上看到的pixel perfect collision detection做法 可以最精確的確認兩個sprite是不是真的有撞在一起,他其實是透過檢查可能撞擊的物件的pixel顏色來判斷是不是真的相撞了,相撞的pixel會是兩個物件的顏色相加。Author: Ninji. I am trying to port the pixel perfect collision detection in Cocos2d-x the original version was made for Cocos2D and can be found here: cheapnfljerseysfootball.com Jan 01,  · Pixel perfect collision detection doesn't sound very useful to me, and here's why: There are 2 parts to collision detection in a physics engine. First there is the 'detection' part, and there is the also the collision response part. The collision response part is responsible for fully resolving the collision (ie. preventing the objects from.

Perfect pixel collision detection cocos2d

First thing is to port a useful and famous function which can detect sprites collision using so called “pixel perfect collision detect” to cocos2d-x. Now i need know how to make a pixel perfect collision detection. Can anyone help me? I see some very complex solutions, i think that have a simple to do it. Hello everyone, I am trying to port the pixel perfect collision detection in Cocos2d -x the original version was made for Cocos2D and can be found here. Hello, I've tried to follow tutorial cheapnfljerseysfootball.com collision-detection-using-cocos2d-x/, but it based on cocos2dx. bool HelloWorld::areSpritesColliding(cocos2d::CCSprite *spr1, cocos2d:: CCSprite *spr2, bool pp) { If we're not checking for pixel perfect collisions, return true. Based on information in this thread (cheapnfljerseysfootball.com collision-detection-cocos2d-x-v3//2) and my previous. Finally solved the problem. Had to use custom opengl fragment shaders to shade one of the sprites completely RED and the other completely. Collision Detection and Scoring Continuing from where we left off in the previous collision detection Box collision detection Per pixel collision detection Box2D. I've seen that a lot of people are struggling with pixel perfect collision detection in v3.x. There is code samples and tutorials to implement this feature for.Is there a well-known way (or perhaps reusable bit of code) for pixel-perfect collision detection in XNA? I assume this would also use polygons (boxes/triangles/circles) for a first-pass, quick-test for collisions, and if that test indicated a collision, it would then search for a per-pixel collision. I am making a space invaders clone on iPhone using Cocos2D v I am getting there with the framework but there is still a lot I don't know. The step I am stuck on comes down to collisions. I need to do two things: 1) I need to do a pixel perfect collision with the fleet of CCSprites that are animated using a spritesheet.

I am trying to port the pixel perfect collision detection in Cocos2d-x the original version was made for Cocos2D and can be found here: That is if I do only a bounding box collision but I am not able to get it working correctly for the case when I need Pixel Perfect collision. I think the. Jan 01,  · Pixel perfect collision detection doesn't sound very useful to me, and here's why: There are 2 parts to collision detection in a physics engine.

This part can't be stressed enough. If you think you need pixel-perfect collisions, you probably don't. Pixel-perfect collision is resource-intensive, computationally expensive, and couples the game's physics too tightly to the visuals. There's a reason why almost all 2D games use rectangles or circles for collision detection.
