The collision box the physics uses (red outline). When this sprite is the player, this is its hitbox. Set it here or with the set hitbox brick; read it with hitbox width/height….

Sounds

This sprite’s own sounds — pick from the sampler’s library or drag a sound from the Audio tab’s Sounds browser onto a row. — = no sound (jump/hurt/attack keep their default beeps; land & footsteps stay silent). Tip: in the sampler’s Sample editor, Save as Sound keeps a trimmed edit as a new sound you can pair here.

Frames live in animation rows — idle, run, jump, throw, plus one row per boss-fight move (strike, power, rising, sweep, airstrike, grab, guard, roll, taunt). Use each row's + to add a frame to that animation (up to 24 each). Click a frame to edit it; the Preview loops just that row. In game the player shows idle when still, run when moving, jump when airborne, and throw for a moment when shooting a fireball — enemies too. In a boss fight each move plays its own row; empty move rows borrow the throw pose.

Tiles are single 16×16 images — pick one under "Tile Atlas" to paint it directly; levels update instantly. You can also send any 16×16 sprite over with "add / update in tile atlas" (matching name = update).

Collision Paint

Overrides how blocks collide without changing their art — works on empty cells too (invisible walls). Brush = single blocks, ▭ = zones, right-click = reset. White outline marks overridden cells. ⌫ erases painted overrides back to each tile's default. 🧭 Nav mesh is a separate layer, not a collision type: painting it adds enemy territory to a cell and leaves its blocks and physics exactly as they are (so paint it right over your floor and platforms). Purple cells show it at all times. Enemies with use navigation mesh ticked stay inside it; enemies with the follow painted trail brick ride along it, and patrol normally when none is within sight range. The ⌫ eraser clears mesh and collision together.

Layers

🌿 foreground

🧱 ground (play layer) ×1.0

🏔 background

Click a row to make it the active layer — that's what you paint on. 👁 hides a layer while editing. Rows are front-to-back: foreground draws in front of the player, background behind. In play both repeat sideways as endless strips — paint one screenful and it fills the horizon — and each scrolls at its own speed, so they drift opposite ways: the background (0.9) lags a little behind you while the foreground (1.1) creeps past in front. Only the ground layer is real: collision, coins, hazards and entities all live there. Foreground and background are pure decoration — no physics, no collision, ever.

Entities

Left-drag paints · right-click erases tiles or removes entities · hover an entity and click its ✕ to delete it · the ⌫ eraser clears tiles and entities · ✋ drags blocks and entities around.

Code lives on…

Each target keeps its own scripts. Select an enemy to edit its settings and code its behavior.

An enemy with an "every frame" script drives itself — patrol speed and ledge-turning switch off, and your bricks take over ("turn around", "touching wall?", "distance to player"…). Enemies without code walk back and forth on their own.

Level scripts are great for timers, spawning enemies, and changing blocks or collision while playing.

Songs

A song is the sampler’s current pattern, rendered by its own engine into a seamless loop. Build a beat, press + song from pattern, then pick it for a level under Level Music below (or from code with the play song brick). ↻ re-renders a song from whatever the pattern is now.

Level Music

Every level, and the song that loops while playing it. Same setting as the music dropdown in Level Design — change it in either place.

Game Sounds

Pair any built-in game sound with a sound from the sampler’s library — pick from the dropdown (grouped by category, ● = your recordings/imports) or drag a sound from the sampler’s Sounds browser onto a row. — keeps the original beep. Pads stay your song workspace — remapping pads never changes these.

Saving stores the whole sampler session — pads, samples, pattern, fx, tempo — in the project (it also happens when you leave this tab), and it restores into the sampler when you come back. The sampler itself is your WS Sampler; edit it in the website repo and run push_to_engine.sh there to bring the latest over.

Loading the sound sampler…

It carries a large sound kit. Leaving now would save an incomplete copy of your sampler session over the good one, so hang tight for a moment.
