ftslicei

ftslicei — Copy a slice from an f-table to another f-table at init

Description

Plugin opcode in emugens.

The ftslicei opcode takes an f-table and copies a slice to a second f-table (similar to tab2array, but between tables). This action is done at init time. For a performance-time version, see ftslice

Syntax

ftslicei ifnsource, ifndest [, istart, iend, istep ]

Initialization

ifnsource -- The table number to copy data from

ifndest -- The table number to copy data to

istart -- The index to start copying from. Defaults to 0

iend -- The end index to stop copying. This is NOT inclusive. 0 means copy to the end of the table. Defaults to end of table

istep -- How many elements to skip. Defaults to 1

Performance
