Arcmelt

The assembly bench for Anodized.

Anodized designs one mechanism at a time. Arcmelt takes those mechanisms and puts them on a robot: import an Anodized design, drag its mechanisms onto a swerve chassis, size and rotate them, and drive the robot's states and triggers — all in one view.

Run it

npm install
npm run dev

What it does

• Import an Anodized .json file. Each mechanism box inside it becomes something you can mount.
• Place mechanisms on the robot in a side (or front) view. Drag to move, drag the handles to resize, hold Shift while resizing to keep the original proportions.
• Draw rectangles, circles, and curves on the same canvas for reference — a bumper, a belly pan, a game piece — with the same move/resize/rotate controls. These are for looks only: they never affect collision checks or mass.
• Drive it. Click a state button to move a mechanism, or flip a trigger switch to run the design's real rules — the same triggers and transitions you set up in Anodized, now live on the assembled robot.
• Check fit. A second Deck tab shows the robot from above, flags parts that overlap or hang too far off the frame, and reports total mass and center of gravity.
• Save / Open an Arcmelt file (.json) to keep your layout. It stores where each mechanism came from, not a copy of it — so if you edit the mechanism in Anodized, re-import it and the robot picks up the change.

Project layout

src/anodized/       copied from Anodized unchanged — do not edit
src/import/         reads an Anodized file, finds its mountable mechanisms
src/assembly/       chassis, placement, collision/mass checks, shapes
src/render/         the two views (side/front canvas, top-down deck)
src/triggers/       runs the states and triggers on the assembled robot

Known gaps

• No 3D view yet — side, front, and top only.
• A collision check compares mechanisms at their current state, not every position they pass through on the way there.
• Unequally-rigged cascade elevators are drawn as if evenly rigged.
