Unreal Engine Blueprint: Developing Hack and Slash Using Spawn Projectile Method

Abstract

Spawn projectile method is an algorithm where projectiles are created and it generates output on the basis of the collision of those projectiles. Spawn projectile methods are widely used in any shooting game in the Unreal engine blueprint framework with a ray-tracing feature or other features. Hack and Slash games are mainly close combat action games where Socket collider methods are used for core features and projectile-based weapons may be used as secondary options or other unique methods which are not widely used in a game. Firing system of first and third-person shooting games, selected assets with a skeletal mesh, secondary attack, or special abilities of a player were successfully implemented by using the spawn projectile method as a central algorithm. This research found that Hack and Slash games also can be designed based on the basic algorithm of spawn projectile method, which is mainly an enhanced domain of the current features of Unreal Engine 4.
