Unreal Engine Helicopter Flying #15 - Object Pool Pattern - Bullet Pooling

In this episode of the Unreal engine helicopter flying system, I am going to implement a bullet pooling mechanism based on the object pooling pattern. The idea is, instead of spawning and destroying bullets when we shoot from the helicopter, we hide and keep the bullet in an array after moving to the hit surface and when we need to shoot again, an already available bullet object is re-used. This approach is good for performance because we avoid unnecessary spawning and destroying of actors.&n...

Unreal Animal herd System - Escape From Threats II

In this episode of the Unreal engine animal herd system, I am going to make some improvements related to the detecting threats and run away system we have already worked on. Previously, even after the threat is registered, the deer characters sometimes can take about 10 seconds to react. That is because they are waiting to finish the current task executed in the deer AI system. Today, we will see how to interrupt that task and make them run away as soon as the threat is registered through the...

Unreal Engine Helicopter Flying #14 - Projectile Hits and Damage

In this episode of the Unreal engine helicopter flying system, I am going to work on how to damage other actors when shot from the helicopter. So, we will be able to shoot other enemy characters and kill them.
