HTML5 achieves 3D and 2D visualization QuadTree quad-tree collision detection QuadTree quad-tree as the name suggests is a tree data structure, each of which has four child nodes, supports 2D plane recursion and HTML5 for 3D and 2D visualization Qu

Path graph (path Geometry);C. Composite graphics (Composite Geometry): Graphics group, transform graphics.Recently discovered that d2d, in addition to drawing different types of geometries, has a powerful function: To determine the relationship between geometry (which is what we often call

Returned directory The collision check of this module is only limited to the detection of points and rectangles, (parallel) Rectangles and rectangles, points and circles, and circles. Therefore, this module is also very simple and can be directly combinedCodeLet's take a look: Point and rectangle: /*** Collision between points and rectangles**/This. Col_poi

First, to create a collision you must add a rigid body (rigidbody) and a collider to the game object, which allows the body to move under physical influence.Two, two objects must have a collider (Collider), where an object must also have a rigidbody rigid body.Thirdly, in Unity3d, there are two ways to detect collisions, one is to use a collider and the other is to use a trigger.1> Collider: A group of components, it contains a number of kinds, such a

effort.After reading a lot of information about collision detection and referring to some code examples, this approach was finally understood by me.To help other developers who are not proficient in math, I think I should write a brief introduction to how this algorithm works quickly. I've also introduced a demo that uses the separation axis theorem and the ActionScript 3 source code for everyone to downlo

In Cocos2d-x 3.0, the onContactBegin callback function does not respond to the problem, cocos2d Collision Detection Well, in fact, this is a temporary release. Recently, a friend wants to make a physical game. In the past, he used box2d for physics. Well, it really takes some time to understand the essence of it, however, it is much easier to hear that this engine has been re-encapsulated once, so I tried i
