Multiplayer Sword Physics Game

What it does

• It's just a simple game
• Anyone can go to this link and join

How I built it

• Node and Express JS - Web framework boilerplate
• P5 JS - graphics framework
• Socket io - To implement multiplayer

Challenges I ran into

• Handling collisions between two separate clients
• The sword swing mechanics needed lots of tweaking to get just right

Features:

• Homebuilt physics (no engine used)
• Homebuilt collision detection/handling
• Navigable world (with moving camera)
• Multiplayer
• Client predicts what other players' next actions will be (decresing sutter)
• Arrow which points to nearest enemy
• Bar for both health and your sword's velocity
• Sounds
• Environment (simple trees)
• Damage is proportional to velocity of sword upon contact

Accomplishments that I'm proud of

• The multiplayer is functional (but not perfect)
• The client predicts what other players' next actions will be (decresing sutter)
• Collision detection across multiple clients functions
• Implementing my own physics, no engine used
• Everything interaction in the world is physics based

What I learned

• The issues and nuances of real-time multiplayer games

Controls / Instructions

• W, A, S, and D controls player movement
• Mouse cursor controls sword
  • your sword tries to line up with your cursor, use this to swing!
• Health Bar (in green)
• Sword Velocity bar (in blue)
