pixel-perfect

Phaser v4 destructible terrain & pixel-perfect collision. Demo sandbox — open one to verify the library does what it says, or pull a demo apart to learn the API.

• 01basic rendering live
  Procedural terrain painted from a `ChunkedBitmap` into canvas-backed Phaser textures. No interaction, no physics — just verifies the rendering pipeline.
• 02click to carve live
  Left-click to carve, right-click to deposit, wheel to resize the brush, R to regenerate the terrain. Watch the chunk repaint counter rise on each edit.
• 03physics colliders live
  Same as 02 plus a Box2D world. Space to spawn balls, D to toggle a green-line collider debug overlay, watch balls land on the carved shape in real time.
• 04falling debris live
  Three shelves on thin necks. Carve the neck and the shelf detaches — DebrisDetector finds the new island, the queue bodies it, and gravity does the rest.
• 05pixel-perfect sprite live
  Drag a circle sprite onto a ring sprite; AABBs overlap (yellow) but solid pixels only collide when the inner edges touch (green). Same test runs against a small destructible terrain patch in the bottom-left.
• 06worms-style live
  Trailer piece. Walk a small circle character across a wide hilly bitmap with arrows / WASD; F throws fused grenades that carve craters and detach cliff slabs as falling debris. End-to-end exercise of the per-chunk collider model under continuous interaction.
• 07image-based terrain live
  Stamp an alpha mask onto the bitmap to build terrain from any PNG / canvas. Two materials extracted from the same image at different alpha thresholds — sand outline, dirt core. Click to carve the result.
• 08sprite playground live
  Drag-and-test sandbox for `PixelPerfectSprite`. Drop your own PNG to swap the sprite's texture; cyan outline traces the alpha mask the collision math actually uses. AABB / pixel-perfect overlap colored against another sprite + a terrain patch.
• 09falling sand sandbox live
  Five fluid kinds (sand · water · oil · gas · fire) with density-ranked swaps and multi-cell flow. Oil floats on water; gas bubbles up; fire walks a wooden plank and burns it to air. Sand still settles to a static variant after ~½ s — press B to drop a Box2D ball onto the resulting pile.
