asterisks

Asterisks example

A clone of the venerable arcade game. Control a spaceship hunting for Asterisks - try catching them all, but avoid collisions!

Game controls:

• SPACEBAR: shoot
• CURSOR LEFT/RIGHT: steer
• CURSOR UP: accelerate

Gamepad game controls:

• Button 'A': shoot
• Left Axis X: left/right
• Right Trigger: accelerate

Techniques used / highlights:

Note that the implementation follows the ECS (entity-component-system) paradigm instead of an object-oriented approach.

• le_ecs - Island's rudimentary Entitiy-Component-System module
• instanced drawing to simulate torus-shaped universe (see resources/shaders/line_art.vert)
• batched line drawing
• simple state machine for game state
• simple animation (explosions)
• Hershey vector font drawing (score, game over message)
• Gamepad input enabled
