Control

A competitive carnival arcade game

Control is a tug-of-war-inspired competitive shooting game for two players, implemented with three PIC32 controllers. Each player uses a joystick and trigger to rotate and shoot a turret. The players’ turrets are located on opposite ends of the “arena” and face each other; one player is on the “blue” side, and the other is on the “red” side.

Gameplay

A player can fire the turret at one of the five targets in the centre of the arena. Hitting a target will change the state of the target to be more controlled by the color of the player who hit it. Each target has seven states, which are as follows: deep red, medium red, mild red, neutral, mild blue, medium blue, deep blue. The target’s LED indicator will change to show the color corresponding to the target's state, where the LED brightness indicates how deep into one color the target is. Every time a player hits the target, the state of the target increments by one in the direction of the colour of the player who shot it.

Once the game commences (through the starting mechanism), a game timer starts counting down to zero (the time is shown on the LED display matrix). When the timer hits zero, the game ends, and the player with the most control of the targets wins. Alternatively, the game ends if the same color controls all targets. When the game ends, the winning player receives a gear as a prize.

During gameplay, each player earns one ammunition per second up to a maximum of five, and loses one ammunition every time the firing trigger is pressed. The amount of ammo for each player is shown by the number of lit LEDs next to the respective turret.
