Opcodes

Note

Opcodes are used in .eff (effect) files - and in embedded versions in .itm (item) and .spl (spell) files - and provide additional features and functionality in all the Infinity Engine games. The effect type field of the EFF V1.0 files and the Opcode number field of the EFF v2.0 files indicates the opcode in use for a particular .eff file. Modifying existing .eff files to change opcodes used, or creating new effects is usually done with modding tools such as WeiDU or NearInfinity. For details on the different opcodes (effects) available in the Infinity Engine games, see the Infinity Engine Structures Description Project
