Antistasis - VR Multiplayer Shooter Game

About

Antistasis is a multiplayer virtual reality shooter game being developed by me and a friend at RIT. The game uses zero-gravity physics, using the Floating Pawn Movement system in Unreal Engine 5.

As the main C++ programmer for the project, I develop the base classes that are critical for gameplay, including replicating properties and RPCs for multiplayer compatibility.

Recent Development

Steam Dedicated Servers

The project was recently configured for the use of dedicated game servers managed by Steam's master server network. A testing app ID is used, as the Steamworks app page for this game will not be set up until the project is closer to completion. Building the game for dedicated servers required switching to a source build of Unreal Engine 5.3.2, which was a significant change.

We are now working on managing players within a "match," which involves a number of gameplay implementation like setting up the game mode, handling player spawn behavior, a server-side points system, and more.

Core Mechanics

Grab-pull

Demo: grabbing a cube

Pull an object toward your hand from afar; holding the grab button until it reaches the hand snaps the object in that hand.

Grabbing a Weapon

Demo: grabbing a weapon

When you grab a weapon, it snaps into your hand, replacing the weapon currently equipped.

Grabbing From a Distance

Demo: grabbing a weapon

Grab-pulling an object for any amount of time will alter its motion gradually.

Grapple Behavior 1: Pull

Demo: grappling with a weapon

When a hand has an active weapon in it, pressing the grab button grapples instead. The "Pull" behavior applies a constant force to the player towards the grapple point.

Grapple Behavior 2: Anchor

Demo: grappling with a weapon

When a hand has an active weapon in it, pressing the grab button grapples instead. The "Anchor" behavior keeps the player at a constant distance from the grapple point, resulting in a circular path of motion.

Wall-grab

Demo: grabbing a wall

Projects the current velocity of the player onto the wall that was grabbed. While the button is held, the speed of the player is maintained, and can transfer to walls with different angles and complex shapes like spheres.
