Usage

Add

Action:Add chess adds this chess instance to a board object.

Remove

Action:Remove chess removes chess instance from current board.

Move

These actions change the logical position only, physical position won't be changed.

• Action:Move chess, or Action:Move chess by UID : move this chess to target tile, the logical z index will not be changed.
• Action:Move chess to xyz : moves chess to specific logical position.
• Action:Swap chess by UID : swaps the logical position with another chess by UID.

Get logical position

Get the logical position of this chess by (Expression:LX, Expression:LY, Expression:LZ).

Get the board UID by Expression:BoardUID, return (-1) if chess instance is not on any board.

Get other chess's UID

• Expression:LZ2UID : get other chess's UID which stands on the same logical XY position with specific z-index.

• Expression:DIR2UID : get UID of neighbor chess, return (-1) if no chess picked.

  • The direction code could be presented by expressions of layout plugin (rex_board_squareTx, or rex_board_hexTx).
  • Add 2nd parameter to indicate the z-index.

Test conditions

These test condition would return true if testing pass, these condition will also affect the current SOL.

• Logical position

  • Condition:Compare LX
  • Condition:Compare LY
  • Condition:Compare LZ,

• Is empty above

  • Condition:No chess above, returns true if no chess is put above this chess. i.e. the count of z-index is 1.
  • Condition:No chess at LZ, returns true if no other chess at the specific z-index.

• On the board

  • Condition:On the board, returns true if this chess instance is at the specific board.

• Are neighbors

  • Condition:Are neighbors (UID) , returns true if this chess and another chess are neighbors.

• Is a tile

  • Condition:Is a tile, returns true if this chess is a tile (z=0).

More samples

• Pick an empty cell randomly -- Sample capx

  • Mix Condition:No chess at LZ with other test conditions and finally pick a chess instance randomly by system action: pick random instance.

• Drag tile/chess on an isometric board -- Sample capx

• Swap chess from two different board -- Sample capx
