Tower Defense

Simple tower defense game.

Graphics assets

Graphics and sounds by Matt. Nathan created the Lego builds that were used for the assets. I took pictures of the ships and used the iPhone foreground cutting tool and some recoloration to create the spites. Then I shrunk them down to appropriate size.

Creeps

SuperCreep (Multiplayer)

Towers

Base

Rules

• Towers can shoot and have health equal to their ammo.
  • When ammo or health runs out it disappears.
  • Players have a budget and can place towers with a mouse click
  • Players can select different kinds of towers with different effects (melee, ranged, AOE)
• Creeps spawn and move down the lane towards the base.
  • When a creep runs into a tower it lowers tower health by some ammount.
  • Or ranged creeps can fire from a distance
  • When a tower shoots a creep it lowers creep health
  • When creep health runs out it disappers
• Base is at end of lane and has health
• Single player to see how long you can go

• Multi-player
  • Against computer to see who lasts longer

Remote viewer

• Make the current game update and draw into scenes
  • Start scene
  • Game scene
  • Game viewer
    • Try sending events out and have them represented in the game viewer
    • Make side by side view in single window before breaking out into separate running app
    • It could share draw logic with the main game scene but need it's own update which will just read the state off the event system
    • Once we have events populating the viewer we can add networking and everything will just work

Network play

Things to send over network: Position, Health, Creep, Player, Tower, Bullet (and render), Game.highScore, Attack (mainly for cooldown, also debug info), Sprite renders (maybe just image name), gameover/paused status
