Today we are going to implement a gameplay ability to lock on and lock off on nearest enemy character. When the player is locked onto a certain enemy, player character will keep looking at the locked enemy regardless of the direction player is moving. This is where we will need the 8 ways movement blendspace we implemented in previous episode.

Today we are going to work on an 8 way movement blendspace to be used when the character is armed with a sword for a melee combat system in unreal. What I meant by 8 way movement blend space is a 2D animation blendspace which allows character to play animations accordingly when character moves forward, forward right diagonaily , forward left diagonally, backward, backward right diagonally, backward left diagonally. Instead of orienting character to the movement, we nee...
Today we are going to work on how to add multiple different light attack animations to our sword attack system. At the moment, we have only 2 types of animations that will be selected based on the attacker and target enemy placement. Today we will add a couple more animations so we don't feel the attacking as same repetitive action.

Today we are going to implement a mechanism lunge towards enemy and close the gap when a melee attack is performed to ensure the attack makes contact with the target enemy. This will be done by calculating the distance between target and the attacker and if the distance is a bit larger to make contact, the location will be adjusted. But this will be masked by the attack animation so it doesn't look obvious. Everything will be properly replicated in a multiplayer environmen...

Today we are going to work on how to focus on the closest enemy when the character do an attack. Player may be facing another direction when the attack starts depending on the gameplay situation. Here, we will see how to make the character rotate and place in a proper distance as the attack is performed without making in obvious to the player. We will be masking the location and rotation adjustment with the attack animation. Everything will be properly replicated acros...
Today we are going to work on Death gameplay ability. When the character's health is fully depleted, death gameplay ability will be activated and this ability will take care of tag modifications and collision disabling of capsule so that it doesn't further interfere with other live characters. As we are working on a multiplayer environment, When a player character is killed by another character, inputs will also be disabled for the character.
Today we are going to work on how to add a blood trail along the sword path when a character is attacked with a sword. This blood trail/streak will be replicated into all the instances of the game.

This is the 16th episode of my new tutorial series on Action RPG game using Gameplay Ability System. Gameplay ability system (GAS) is a framework introduced by epic games that is designed to support a data driven gameplay programming architecture. Today we are going to fix following issues in the action RPG project. - Sword duplication bug on owning client. - Prevent collecting weapons when character already owns the weapon. - Sword trail fixes.
In this unreal engine tutorial, I am going to continue with replicating the character interactions system I have worked on previously. Here we have implemented ways for player to interact with objects in the world. Such as, sit on a chair, sleep on a bed, exercise using a barbell etc. Last time we implemented necessary changes to properly replicate animations and interaction montages across clients and server. Today, we are going to look into how to make the interactable o...

Here is a free playable demo of the unreal engine portal gun system I have implemented. This is inspired by the portal game you all are familiar with. You can watch the full series where I explain in detail about the way I have implemented this system. Here you can jump through portal and shoot projectiles through portals. Also you can place portals in any supported surface.
Today we are going to add a sword trail to the attack ability we have already implemented. When the character do an attack with the sword, a trail will appear along the movement of the sword and this trail effect will be replicated across server, client and all the instances of the game.

In this episode of Unreal Engine Space Toolkit system tutorial series, I am going to implement a local gravity system for the space ship. That means, when the player enters spaceship, A localized gravity force will be applied to the character so that the character can walk inside the spaceship in a natural way. You can think of this as a sort of magnetic boot mechanism if you like. Once the character exit the spaceship, there will be no gravity if the character is outside ...

In this episode of the unreal engine planet generation system, we are going to work on how to spawn multiple foliage types. We can define rules such as what elevation range on a planetary landscape that a certain foliage type grows and based on that we can automatically place different types of foliage in a planetary landscape.

In this episode of the unreal engine planet generation system, we are going to work on how to spawn trees in a cluster. That means, instead of spawning 1 tree instance i various places on the planet surface, There will be a cluster of trees. This would simulate an organic growth and spreading of trees and it will give a more natural look to the foliage placement.
In this episode of the unreal engine planet generation system, we are going to work on a how to define a height or ground elevation region that the given foliage type grows. In a flat landscape, we can simply check the Z component of the landscape location and see of that is within the height range of the foliage type. But on a planet, we need to consider the distance from the center of the planet when we check the landscape height or elevation. We will see how to do that ...

In this episode of the unreal engine planet generation system, we are going to work on a foliage spawner for a planetary landscape. Here, we will be using vertex positions and place trees with a random probability on planet mesh. The tree will be aligned to the center of the planet. So it will stay normal to the planet surface no matter where it is placed. We will look into how to do the required calculations to determine the location and rotation of mesh instances of tree...

In this episode of the unreal engine planet generation system, we are going to work on a LOD system for the planet. Initially the planet will be rendered with a relatively low polygon count and when the player go closer to the planet surface, based on player's location, the level of detail on the planet surface will be increased by increasing polycount and applying height details. Everything will happen dynamically through geometry script and dynamic mesh system.
In this episode of the unreal engine planet generation system, we are going to work on a cubic grid system for the planetary landscape. The reason we need a grid system is because unlike a flat landscape, a planet landscape has a spherical shape and it is hard to divide the planet surface into tiles. So, we are going to implement a cubic grid and we will divide the surface area of the planet based on which cube a particular section of the landscape mesh is contained on...
In this tutorial, I am going to show you how to add details to the auto material. When we look at the planet from a distance, we will see the mail colors of the planet which have been automatically painted based on the landscape features. When we go closer, that means when the player actually land on the planet and walk on it, we will see the actual micro level texture detail of the planet. So, we will be working on how to blend macro and micro level details for the planet...

Today I am going to show you how to bake a dynamically generated planet as a static mesh. A new static mesh asset will be created and saved into the project and the created static mesh will look same as the generated planet. Here, we will have to use some C++ part for the asset creation part and register it with the asset registry.

Last time we implemented a gameplay ability to react to sword attacks and we triggered it using "Send Gameplay Event' function. But the SendGameplayEvent functions are not replicated by default. Today, we are going to implement a remote procedural call (RPC) to replicated SendGameplayEvent function. So that the reactions will be shown on characters across all the instances of the multiplayer game and we would be able to damage client to client and client to server and all ...

Here we are going to look into how to use "Activate Ability From Event' feature in gameplay abilities. The importance of this event is, we can access event data which contains instigator and some other useful data that comes as a parameter in this event. In this example we are working on, we will use the instigator value to rotate the character towards the attacker when it get hit. We will use ability triggers and send gameplay event to actor to activate the abilitie...

Today I am going to research on how to create a grid system on the surface of a sphere. I am planning to implement a LOD system for the planet generation system we have worked on and as for the first step of that, we need a way to divide the surface area of the planet mesh into a grid. So, here we are going to figure out how to do that.

Here we are going to implement a gameplay ability which allows player to damage and kill other players in the game. As this is a multiplayer game, everything is replicated. So, when the player equip sword and attack other characters in the world, they will receive damage and then when the health drops to 0, they will die. Health is implemented as a attribute in a gameplay attribute set. So we will implement a way to listed to attribute changes in the character blueprint us...

Today, we are going to look into how to add a gameplay attribute set into our character. Gameplay attribute sets contains attributes such as health, stamina, etc. and we can use them to store, update and the status of character in game and replicate it over the network. We can modify these attributes through gameplay effects. For example, if we apply a damage gameplay effect to a character, the health attribute will be reduced by a given number of points. In this episode, ...
