How Interactions (should) work

• user clicks on pixel
• retrieve function signature
• if just DefaultParams : prep action function -> return
• prep Param objects for each
  • has transformer? (prefix with "crc","crv", "crs")

Function signature fields

Example from RPS:

• first_move(crc_move_Move)
• second_move(move)
• finish(crv_move, crs_move)

"Param.transformer()"

Param Transformers

• "crc_VARNAME_VARTYPE": CommitReveal: Commit

  • collect variable value from UI
  • create salt
  • Hash variable with salt
  • submit the hash as felt252
  • store VARNAME+SALT in KVstore for later retrieval

• "crv_VARNAME": CommitReveal: Value

  • retrieve value of VARNAME from storage
  • submit value

• "crs_VARNAME": CommitReveal: Salt

  • retrieve value of SALT from storage
  • submit value

• ContractCall

• Params

  • StringParam
  • NumberParam
  • EnumParam
