The use of triggers in game making is very convenient and very practical. This is a brief introduction to how to use a simple trigger to achieve the automatic door closing effect.First make sure that you have animated settings on the door.The specific process is as follows.Select Window->animation to open the Animation window, select the door where you want to add the animation, and click the Red button to create a new animation.After selecting a feature that needs to be animated (such as Post

From: Himi "Android game programming from scratch" www.himigame.com A collision listener Interface "Contactlistener" is provided in box2d, which uses an interface that requires rewriting its four abstract functions. @Override public void Add (ContactPoint arg0) { //TODO auto-generated Method stub //Collision, response to this function when there is a new contact point } @Override public void persi

Optimized in the afternoon ProgramThe process caches some things, greatly improving the collision detection speed. Currently, the four 57600-sided motion teapot collision detection (six frames per frame) can be maintained at around 20 FPS in the box frame mode (note: the speed of the box frame mode on non-professional graphics cards is slow ). The score is satisfactory. At least enough applications are ava

The navmesh system provided by unity3d can easily solve the game Path-seeking problem, but the system has a problem that is hard to understand: 　　In navmesh navigation, the physics system collision will be ignored. That is to say, navmeshagent will not be blocked by collider while moving, but will go directly (but ontriggerenter and other trigger functions are normal ). 　　The Dynamic Collision function is a

Recently learned a process for detecting collisions with a scan line algorithmOriginally not called scanning line algorithm ...Take 2D games, the objects in the game are AABB box (3D games can also be used in this way.) The game is divided into X, y two dimensions, 3D divided into X, Y, z three dimensions)1 first line in the direction of the x-axis, all objects are projected onto the line, so each object on the lines are mapped to a line, there is a start start, end point end.2 Save the data as

Sometimes, we need to show the collision box in the game view, such as fighting games I want to develop a collision configuration tool, I often need to see the collision box, today I looked for a bit, did not find the right plug-in, I also spent $5 to buy a plug-in, the results are only in Scene view display, I need to be able to display this in the game view and

All ports opened on firewalls and routers are a security risk. This is also the value of port knocking. Port collision technology is a technology that allows access to firewall services with pre-configured "Collision. The so-called collision is composed of a sequence of attempts to access the system to close the port. These attempts are either recorded in a log o

The Export and Import of research scenarios were conducted last week. The first problem was the export of collision bodies. First, copy everything in tools \ max2dtsexporterpro \ max_install under the SDK directory to the max directory. Remember, this export plug-in only supports max8 at the latest.Then, find Chapter 8. Exporting shapes from 3D Studio MAX: max2dts. This article has been around for a long time. Unfortunately, it has reached max9 and i

the wall:All two objects that collide are added collider, and the moving object is set to add a rigid body (a capsule child object is added to the camera, and collider and Rigidbody are loaded capsule's parent), But to prevent the wall from going through the rigidbody component of the constraints attribute, respectively, there are Freeze Position (x, Y, z) and Freeze Rotation (x, Y, z), fixed position and angle,Freeze Rotation ( X, Y, z) which axis to hook on, after the

There are a lot of messages in Monobehaviour, a total of 62!In addition to a series of functions that must be followed in the life cycle of the script, there are two other sets of more frequently confusing messages: collisions and triggering.According to 3D and 2D objects, and divided into collision: collision, collision2d. Trigger: Trigger, trigger2d.Taking the three-dimensional object as an example, the f

In the cocos2dx of the collision detection of the rectangle needs to do a collision check of the rotated rectangle, because the game does not use the box2d and other physical engine, so the obb (oriented bounding box) direction bounding box algorithm, the algorithm is based on the SAT ( Separating axis theorem) separates the Axis law.　　Separation Axis law: Two convex polygon objects, if we can find an axis,

Collision Detection, also known as conflict detection, is a method to determine whether the elves conflict with each other. Collision Detection is used to determine when a physical interaction occurs between Elves. For example, in a game, if the player genie collide with the little plane genie, the player's life will be reduced. Collision detection is a mechanism

In the development of Java games, we often encounter collision detection problems. As in the tank war, the shell and tank encounter exploded; in the Guardian game, the Guardian Fire Arrows and monsters meet the Monster blood loss; In a plane game, the plane sent bullets and enemy planes met to kill enemy aircraft. These all need to implement collision detection.We first look at a relatively simple
