Unreal Engine 4 C + + Platformergame custom role Controller source code analysisThe official store has a platformergame the entire free game, is a scroll class parkour game. The role controller of the whole project is very interesting, can run, jump, glide, cool. Here to analyze how it is implemented in detail.Ucharactermovementcomponent This class implements mos

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

(radiantstaticmeshwebviewactor)After clicking on the simulate , the simulation results are as follows:Drag into the game scene, position it, and then run:Eighth Step:Let's be free to explore something in this blueprint :First look at this component and see the details:where refresh rate is the update frequency (if the value is 1, the video in the screen, the page effect will be one second frame). URL: Web page. Size: The dimensions of the Web page (resolution, etc.). Mouse Effects:Set the size

binding.protected:virtual void Setupplayerinputcomponent (class uinputcomponent* inputcomponent) override;The following are the specific implementations of each method:void Asqxgamecharacter::setupplayerinputcomponent (class uinputcomponent* inputcomponent) {check (inputcomponent); Nputcomponent->bindaction ("ZoomIn", ie_pressed, this, asqxgamecharacter::zoomin);inputcomponent-> Bindaction ("Zoomout", ie_pressed, this, asqxgamecharacter::zoomout);The Setupplayerinputcomponent method binds two a

First, block module multiplexingDefine blocks that need to be reused with blockBlock followed by the name of the module, referenced once the block content will be reused oncePost-compilation results:II, inheritance template (extends)In the actual development, the site's head, the tail is generally common, we can through the Jade template inheritance (extends) function, the public part of the abstraction, and then let the different pages inherit these public parts, and inherited it can also be re
