Wiki Page Proposals

The purpose of this page is to let other Wiki contributors know your plans and so we can more easily collaborate on interconnecting articles.

• It may not be a good idea to pluralize reference pages, can be linked in plural using VV1VV. For guides such as Movement Mechanics it should be fine.
• Remove prefix (T,F,E,U,A) like Interfaces In C++ the property system is discussed through out the page.

Project

• Templates - Perhaps tutorials expanding on these.
• Directory Structure - Also understanding redirects
  • Cleaning Your Project
• Game Framework explained
• Every project needs a version control system
• How Continuous Integration boosts development

API

When writing code for UE4 its not exactly the same as C++, there are alot of helpers and special types in the Engines API.

• Unreal Property System

  -   

    The C\# tool chain (Build Tools) in UE4 such as UHT & UBT needs mentioning. A list of common [Errors & Warnings](/Errors%20&%20Warnings) that arise when using UHT & UBT, help point people in the right direction.

• Modules (Anatomy of plugin)

  -   

    Including Editor Modules (tool plugins), Content Only Modules (blueprint plugins) etc - Not covered here [Creating C++ module](/Creating%20C++%20module)

• Memory Management

  -   

    Smart pointers, reference helpers and other T types. Reflection, referred to on this page as UObject System.

Basics

• Flow Control - If / Else If / Else, While, Return, For etc (Blueprint as well)

Member Types

• Numerical Types - Mainly in relation to Unreal Engine 4 uint32, byte. (could also contain float for completeness)
• Compound Types - Could also be known as Structures but could possibly include, classes.
  • Vectors - Can discuss some basics on using vectors, vector operations (including dot and cross) as well as more advanced topics such as normalizing vectors (unit vectors) and conversions to rotations.
  • Rotators - Topics such as conversions to different value types such a radians, degrees, etc. More advanced Quat.
  • Colors - Include other color types such as Linear Color.
• Container Types - Base page for all container types.
  • Arrays - All information on the different array types can be found here from TArray to Sparse.
  • Maps -How do we name Type pages Map (Container), specifies that its a container type in the title. Do we do this for all Containers?
  • Curves - Unreal Engine 4 contains many different types of curves used throughout the editor interface. (UCurveVector, UCurveFloat)
• Functions - We could include function pointers and references. Events - Delegates

Core Classes

• Basic Class Structure
• Game Framework explained

Gameplay

• Movement Mechanics - A guide to basic movement and physics in the Character Movement Component.
  • Components (CharacterMovement, FloatingPawnMovement, Movement, NavMovement, PawnMovement, ProjectileMovement, RotatingMovement)
• Multiplayer - Networking, Authoritative Server Model, Replication (GetLifetimeReplicatedProps), Travelling.

Technical Art

• Skeletal Meshes - Animation systems behind Skeletal Meshes as well perhaps.
  • Animation - Root motions, physics based animations.
• Static Meshes - Can contain information on HISM and HLODs
• Materials - Parameter Collections, Material Instancing, Layering.
  • Shaders - Expansion into deeper technical topics HLSL.
• Post Processing
• Particle Effects - Niagara is out of beta as of 4.25, can start pointing people towards using this as default. UParticleSystem vs UNiagaraSystem.
• Splines - Spline Component, Spline Meshes and other topics where they may also be relevant such as relating to Curves

Audio

• New Audio system vs old, HRTF and all the other cool things going on in Audio right now. Environmental Soundscapes using 3d audio etc.
