Tags: blog HTTP ar SP Div on 2014 art log Taking the official Third Person template as an example, the uspringarmcomponent in the character blueprint implements most of the camera and scene collision and interaction functions. To implement camera latency, you only need to modify the attributes in the lag column. The first one controls the latency when the camera moves, the second is the latency when the camera rotates, and the other two are the latency speed. The smaller the latency, the mo

VR Common Operation Interface UE4 provides a set of HMD functions in blueprint, as shown in:In addition, for gear VR, you can open the Oculus Library plugin, access the function:Common functions implement the Gear VR helmet has a touchpad on the right, and is tested to respond to its actions via the touch event in the blueprint, for example:In addition, the current VR is commonly used in the way the viewpoint interaction, need to use line of sight detection, for example:Unreal

The default, open UE4 Editor, the video card will render the scene at full speed, on my machine, is 120FPS. The whole machine began to roar and the resources were too much occupied. In fact, there is absolutely no need for this, the frame rate of about 60 is enough.How to modify it, try a lot of ways, the most effective is to modify the Baseengine.ini configuration file, modify the following line:Smoothedframeraterange= (lowerbound= (type= "erangeboundtypes::inclusive", value=5), upperbound= (Ty

to the right-click, add Event-in the blueprint. Custom events can specify input parameters, and can also specify whether the event can be synchronized on the client and server side.Replication has four options, which are not replicated by default, can be selected for multiplexing, run on the server, run on the client to which it belongs, and can be selected if the event needs to be routed over the network.Enter a value column to add parameters, the same type as the variable type.Let's do an exa

Sometimes when we create a scene, a particular actor we want to give it a specific icon for easy observation. such as this:It is also very simple to implement, and you need to write C + + code:We create an actor called Amyactor, which contains a sprite (sprite), which is responsible for displaying the custom icon: the code is as follows#pragma once#include "gameframework/actor.h" #include "components/billboardcomponent.h" #include " Myactor.generated.h "/** * */uclass () class Nantopdown_api am

processed template display, where the template file does not add the path, as long as the use of a file name, it is the path we have already defined in $smarty->templates (Stringpath).After the execution of the program we can open the current directory of the Templates_c and the cache directory, we will find a few more than a few percent of the directory, these directories are smarty compilation and cache directory, it is automatically generated by the program, do not directly modify these gene

simulate a suspension system and a speed control system? Will the screen shake when a player has a cannon? Basically, it is the work of designers who make the game feel good, but it requires the work of programmers to implement it. Do not be afraid to write some special test cases to get the correct results. For example, a common technique used in testing is to set "flag" for objects ". When an object is in contact with another object "ground", you can set a "grounded" flag to true for this obj
