java collision detection

You can find many methods for rotating rectangular Collision Detection on the Internet.ArticleThis collision detection was analyzed: the OBB collision detection. This article is mainly to add some of its own analysis of the detail

In-game collision detection is divided into two stages: broad phase and narrow phase. The next thing to introduce is broad phase. At this stage of broad phase, our main task is to screen objects and filter out the objects that are most likely to collide . Imagine that there are N objects on the screen, and if we have collision

Control and collision detection by genie In the previous section, we learned how to plot, move, and implement animations. Finally, we implemented simple animations for the three rings. Today we learned how to control the genie through devices, the content in this section is relatively simple and easy to understand. Here I first paste all the code of the control genie to facilitate the next learning! Using

In Unity3d, an object usually consists of a collider and a rigidbody. Collider is a collision body, an object is a collider, before collision detection can be carried out. When the "is Trigger" attribute item in the collider component is checked, the object becomes a collision detector. Objects have rigidbody componen

Today, I saw an article in csdn, writing the collision detection between the rectangle and the circle, learning from the author's detection ideas, I used it in the cocos2d-x. Original article address: Click to open the link The collision detection between rectangle and the

first, a new cube, which itself has its own Collider collider, as shown in Figure To use trigger to detect object entry, you need to tick the IS trigger optionCollision detection trigger trigger is different from the collision detector collision, which can be unaffected by physical effects, some can penetrate the area of the

Label:A small demo of the collision, with a ball to hit a wall, the result of both the ball and the wall are set the rigid body and the collision body case, the ball through the wall. Moving the ball's position, the ball can sometimes pass through the wall, sometimes blocked by the wall.For the ball through the wall, the problem, in the Internet to find the answer, the basic can be determined that the reaso
