fxgl-placeholder-art-prompts

Generate AI-image prompts for temporary placeholder art in FXGL games. Optimize for gameplay readability, exact dimensions, consistent perspective, transparent backgrounds, and FXGL spritesheet compatibility rather than final production polish. Use this skill when a prototype needs usable stand-in art for sprites, portraits, UI icons, or environment tiles while real art is pending.

fxgl-particles-effects

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, explosion, smoke, rain); apply image-textured particles with multiplyColor / toColor; write custom per-particle physics via setControl; attach TrailParticleComponent for motion trails; apply SlowTimeEffect for bullet-time; apply WobbleEffect for screen-shake; stack multiple effects with EffectComponent; build fireworks displays. Use this skill when adding explosions, fire, smoke, rain, motion trails, impact bursts, bullet-time slow-motion, screen shake, or any particle-based visual polish.

fxgl-project-starter

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 using the same questioning approach for initialization choices, and require documentation updates plus automated tests for every implemented step.

fxgl-breakout

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 bottom-drain loss, spawn falling power-ups, and finish the level when all breakable bricks are destroyed.
