Add particle systems and visual effects to an FXGL game — configure ParticleEmitter with function-based setters (setVelocityFunction, setAccelerationFunction, setExpireFunction, setScaleFunction, setSpawnPointFunction); use built-in factory emitters (fire,…
Start a new FXGL project through a bounded Socratic discovery flow, then turn the answers into a docs-first starter specification with ADRs, an arc42-lite architecture summary, and Mermaid use-case diagrams before scaffolding the project itself. Continue…
Build a Breakout or Arkanoid style game in FXGL — control a paddle horizontally, keep a ball at constant speed, bounce it off walls, paddle, and bricks, load brick layouts from level data, angle the reflection based on paddle hit position, handle lives and…
Build a first-person 3D game in FXGL — set up a player-driven Camera3D, implement mouse look, move relative to the camera facing direction, add a crosshair HUD, raycast or pick 3D targets, simulate gravity and jumping, and manage a first-person weapon or…
Build an incremental idle or clicker game in FXGL — click for resources, buy auto-producers, scale costs exponentially, show passive income in the HUD, unlock upgrades by milestones, calculate capped offline progress on load, format very large numbers, and…

Build a rhythm game in FXGL — parse a beatmap, spawn notes early enough to scroll into a hit zone on time, score inputs by timing window, handle combo and grades, support hold notes, and keep chart timing aligned with audio as closely as FXGL's current audio…
Build a Snake game in FXGL — move on a discrete grid by timer steps, store the body as a deque of grid cells, grow when food is eaten, buffer direction changes, detect self-collision and wall rules, increase speed as the snake grows, and support multiple food…
