Starbreaker

A neon vector take on the arcade classic Asteroids, built with Fyne. Drift through a glowing nebula, blast the rocks into ever-smaller pieces, dodge the hunting saucer, and clear wave after escalating wave.

Showcase

Starbreaker is a demo of two new Fyne canvas primitives:

• canvas.ArbitraryPolygon — the ship, rocks, saucer, life icons and shots are all stroked vector polygons with per-corner geometry, drawn straight from the model each frame and wrapped seamlessly across the screen edges.
• canvas.Shader — the animated backdrop is a GLSL fragment shader (a drifting magenta/cyan nebula, a twinkling starfield and a soft vignette), driven by canvas.NewShaderAnimation. Desktop OpenGL and OpenGL ES/mobile/web sources are both supplied.

Screenshot

Play

go run .

To build a standalone binary:

go build -o starbreaker .
./starbreaker

Controls

Input	Action
← → / A D	Rotate the ship
↑ / W	Thrust (momentum carries you)
Space	Fire · start · play again
H / ↓	Hyperspace — jump to a random spot (no protection!)
P	Pause / resume
R	Restart
M	Mute / unmute (remembered between runs)

A tap or click also starts the game and fires.

How it plays

• Three ships. Lose one whenever a rock, the saucer or a saucer shot catches you. A fresh ship blinks while it's briefly invulnerable. Out of ships, it's game over.
• Split the rocks. A large rock breaks into two mediums, a medium into two smalls, and a small shatters for good. Smaller rocks are worth more (20 / 50 / 100) and move faster — clearing the field is a race against the chaos you create.
• The saucer. A hunter crosses the field now and then. The big one sprays wildly (200 pts); the rare small one aims true (1000 pts).
• Bonus ship every 10,000 points.
• Rising waves. Each cleared field spawns a larger, faster one.

The whole world wraps: fly off any edge and you reappear on the opposite side, and so do your shots and the rocks.

Overview

Starbreaker — a neon vector take on the arcade classic Asteroids, built with Fyne. Drift through a glowing nebula, blast the rocks into ever-smaller pieces, dodge the hunting saucer, and clear wave after escalating wave.

The ship, rocks, saucer and shots are drawn with the canvas.ArbitraryPolygon vector primitive; the animated backdrop is a GLSL canvas.Shader.

Controls:

← →  / A D     rotate
↑    / W       thrust
Space          fire · start · play again
H / ↓          hyperspace (random jump)
P              pause / resume
R              restart
M              mute / unmute (remembered between runs)

Play also pauses automatically whenever the app leaves the foreground.
