Tags: Unreal Engine character Taking the official Third Person template as an example, the uspringarmcomponent in the character blueprint implements most of the functions such as camera and scene collision and interaction. 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 laten

Unreal Engine 4 RenderTarget making live camera effectFirst on the effect:Live camera I do not know how to translate, anyway, the meaning is to render a camera image to a 2D plane.The following are the specific implementation methods:1. Create a scene Capture 2D objectDrag the object to the appropriate place.2. Create a Rendtertarget objectRender target, Material map3. Setting the properties of an Scenecap

In the game development often uses the ray collision, for instance the laser shot, needs to know clearly its centralized position, then releases the attack effect at this point.Unrea Engine 4 To do Ray collision is also very simple, the main function of the implementation is the world Linetracesingle this method, the following gives the test code. The code I tested in Thirdpersontemplate. Detects the actor

Unreal Engine 4 C ++ creates a Zoom camera (source code) and unrealzoom for the role In the game, observing the role's camera can narrow down and pull far is a common requirement, and UE4 is easy to implement. This article uses the TopDown template as an example to explain how to implement a Zoom camera step by step. After creating the C ++ project of the TopDown template, we will get three important classe

log is not seen on both the server side and the client. It will appear in the Artpawn and Artplayercontroller clients.Server function:Server Funcionn is a call from the client to help me, for example the client will say: "I'm going to perform an action and you have to make sure you respond to the event on the server side.""For example, an EXEC function is executed only on the local client, and the server side does not have the corresponding action, this time to be notified." Perform an instance

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

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
