This is the Unreal Engine Developer course – it started as a runaway success on Kickstarter and has gone on to become one of the bestselling Unreal courses on the internet! Continually updated in response to student suggestions, you will benefit from the fact we have already taught over 360,336 students game development, many shipping commercial games as a result.

You're welcome to download, fork or do whatever else legal with all the files! The real value is in our huge, high-quality online tutorials that accompany this repo. You can check out the course here: Unreal Engine Developer

1 Intro, Notes & Section 4 Assets Battle Tank is an open world tank fight This will be a head to head battle Other player can be human or simple AI Heavy focus on control systems Also learning terrains, UI, terrain sculpting & more Dive right in and enjoy yourself!

1b Battle Tank Overview An overview of the finished Battle Tank project.

2 S04 Game Design Document (GDD) The Concept, Rules and (initial) requirements We’ll iterate around a loop while making this game Constantly asking “what’s least fun” Remember we’re not AAA studios Let’s find the essence of fun of this game.

3 Setting Up a GitHub “Repo” Creating an online repository for your project GitHub provides public hosting for free We will use their default UnrealEngine .gitignore We’ll then “clone” this repository to our machine How to use a readme.md with markdown*

4 Creating & Deleting Landscapes Creating an Unreal project in an existing “repo” What’s good about Landscapes in Unreal Engine How to add a Landscape in Unreal How to delete a Landscape in Unreal.

5 Landscape Setup & Scaling You can change position & rotation later Scale will impact terrain size, so set on creation How to choose your “Section Size” The effect of the “Number of Components” Creating a landscape of a specific scale.

6 A Landscaping Process Sculpt: hills, valleys & flat areas Smooth, flatten & ramp: create useful features Erosion & noise: make it more organic Paint: use layered materials Details: add details (foliage, trees, etc)

7 Upgrading Engine Version Epic games launcher helps manage versions Remember to commit your project first You can then “Convert in-place” Check your project runs OK in new version Close everything and re-commit How to tag a commit in GitHub.

8 Using Landscape Layers Create a material for your landscape Set Usage > Used with Landscape LandscapeLayerBlend node & Vector Parameters Add at at least two layers & create LayerInfo Paint the landscape from the Modes tab Screenshot and share with us

9 Flat Shading Low Poly Landscapes Unreal’s tools are setup for photoreal landscapes Once you set the bar high, the rest must match An alternative is to opt for a low-poly look... ...then you can focus on gameplay, story, sound Can be a good choice for smaller teams How to make low-poly, flat-shaded landscapes.

10 More Landscaping Tools How to make flat shading optional Importing and exporting landscape heightmaps Reducing the resolution of a landscape Using a texture in a landscape material.

11 Tank Control System Support keyboard, mouse & gamepad controller Mapping player intentions to control inputs Mapping control inputs to actor actuators Introducing the concept of “fly by wire”.

12 Actors from Multiple Meshes Import the tank in 4 static mesh parts Assemble the parts using sockets Create our Tank_BP and test.

13 Configuring a Tank Add mass to the tank Fine-tune track position Replace root component in Tank_BP Enable physics and assign a mass Set the tank as the Default Pawn Setup PlayerStart and debug start collisions.

14 3rd Person Camera Control Horizontal Coordinate System Setup a Camera Spring Arm Why the Spring Arm alone isn’t enough How rotations don’t “commute” Binding mouse and gamepad to camera control.

15 Fixing 3rd Person Camera Rotation Use a Scene Root as azimuth gimbal Use the Spring Arm for elevation control Adjust the Spring Arm length Set the camera rotation to 0 (down the arm) Decide if you want the camera to roll or not.
