Unreal Engine Diaries #8


  • When adding new input parameters to a function that's already being called multiple times throughout the project, it's always better to immediately check every instance of the function call to make sure that the new input parameter is connected as required.

  • Drag & drop a variable from the variables list onto a get/set node of another variable to automatically replace the second variable with the first.

  • When attaching moving physics actors to the player character without physics handles, disable it's gravity & set the linear/angular velocities of all of it's components to zero in order to have it simulate physics & collision on the move.

  • Under default conditions, when a character changes it's direction of movement, it instantaneously turns to face the new direction. To change this behavior and enable smooth rotation based on direction changes, first go to the AI character blueprint >> Character Movement Component >> Enable "Orient Rotation to Movement" & set "Yaw" of the "Rotation Rate" based on how smooth the bot turning movement has to be. Then under the default attributes of the blueprint, disable "Use Controller Rotation Yaw" and it should now start having smoother turning movements.

  • If you're experiencing automatic brightness changes in your game, you can disable this effect by going to your viewing camera component >> Post process settings >> Auto Exposure >> Set min and max brightness to the same value.

Unreal Engine 4 Tutorial: Smooth Zoom using Mouse Wheel for Top Down Template

Well, I had already written a tutorial for implementing Smooth Zoom functionality for Top Down Template. But it was based on keyboard inputs. Since most Top Down PC games use mouse wheel for zoom, I decided to make a tutorial for the same. The core logic here is the same as the one implemented by Ryan Jon for the custom camera in his RTS Community Project. If anyone's interested, they can get the code for the RTS Community Project here:

Anyways, he has replaced the default camera for the characters with a general camera since that's more ideal for developing an RTS game. Since a basic Top Down game with a single playable character does not need a separate custom camera, I decided to implement the same functionality for the default player camera in UE4's Top Down Template. So let's get down to it.

First of all we need to make a custom curve from the content browser. We will be using this curve to define the smooth camera movement while zooming …

Unreal Engine 4 Tutorial #4: Basic HUD Based Command UI for Top Down Turn Based Games

Hi, welcome back for the next tutorial. And in this tutorial, I'll be explaining how to create a basic Command UI for top down turn based games using HUD blueprints. By the time we reach the end of the tutorial, we'll have a Command UI with movement and fire action commands, and a player character that responds to the commands. Here's a screenshot showing the end product: 


Oh, and this tutorial is gonna be quite big, compared to earlier ones. So I advise everyone to go through the screenshots, before reading through. If it's clear, there's no need to read through the whole thing, partly because I've written this with a beginner audience target in mind. Ofcourse, if you have doubts, I hope they will be clarified in the written description. If not, feel free to ask me in the comments.
So let's get started. Again, I'll be starting with the top down template. First of all, we need to create a new HUD blueprint. If you're a beginner, you can find this by f…

Unreal Engine 4 Tutorial #3: Unit Selection Decals for RTS Games

Hi, welcome back for another UE4 Tutorial. This time, I'll be walking you through how to set up unit selection decals for RTS games. So the decals need to be visible, when a particular unit is selected, and set to hidden as soon as the unit is deselected. For this tutorial, I'm gonna start off from the Unreal Top Down Template.

First of all, I'll be changing the default controls a bit. Instead of using left mouse button to move the units, I'll be using right mouse button for character movement. I already have a decal texture, that I created in GIMP. If you don't have one, you could get my decal texture from the link below:
DropBox: Character Selection Decal Texture
So once you have the texture ready, next step is to set up your decal material. For creating a decal material, we need to set the 'Material Domain' in the details panel to 'Deferred Decal'. I'm also setting the blend mode to 'Emissive' in my case. Then we multiply the texture wit…
