RexBoard MiniBoard And Composite

Use this skill for grouped chess pieces that should move, rotate, mirror, drag, or place as one composite object.

Use This First

Choose MiniBoard when:

Need	Use
Several chess pieces act as one shape	`MiniBoard`
Drag/drop a composite onto a board	`pullOutFromMainBoard`, `canPutOnMainBoard`, `putOnMainBoard`, `putBack`
Rotate or mirror a composite	`rotate`, `rotateTo`, `mirror`
Validate placement per child	`putTestCallback`

For a single chess piece, use rexboard-board-and-chess or rexboard-movement-and-pathfinding instead.

Required Setup

This skill assumes RexBoard setup, a main board, and a compatible grid. If not, use setup, grid, and board skills first.

Core Rules

A MiniBoard has local tile coordinates for child chess.
putOnMainBoard maps local coordinates onto the main board.
Use canPutOnMainBoard before committing placement when placement can fail.
Use pullOutFromMainBoard and putBack for reversible drag/drop flows.
Keep MiniBoard and main board grids compatible unless implementing a deliberate conversion.

Gotchas

Mini-board rotation and mirror operations are not the same as moving one chess piece.
MiniBoard child chess are Phaser game objects; use a normal board if the workflow needs plain data pieces.
